From Simple to Sophisticated, This Year’s
Trade Shows Have Gone Virtual
You log on to the trade show website at the designated time, where you’re greeted by Tony, a three-dimensional, fully animated avatar.
Tony provides you with a guided tour of the entire exposition center, including the auditorium, break-out discussion rooms, exhibit hall, virtual lounge, and information booth.
Welcome to the world of virtual trade shows, where real-time demonstrations and interactions are commonplace. While the COVID-19 pandemic has put the kibosh on in-person trade shows this year (including the 2020 Irrigation Show), virtual shows have stepped up to fill in the gap.
These shows offer numerous benefits: they can save both time and money, and they can extend a company’s global reach. But virtual events are not without their own challenges. For instance, they must present compelling content that will keep their audience continually engaged.
Here are a few things to keep in mind when sponsoring, exhibiting at, or attending a virtual show…
Sponsoring a Virtual Trade Show
The first question you need to ask yourself as a virtual trade show sponsor is: How sophisticated do I want my show to be? Virtual shows run the gamut from simple online interviews and basic webinars to second-generation avatars like Tony, who can move from booth to booth and event to event.
If you choose to go with the basic approach requiring no special technical platform, make sure your presentation materials are concise, engaging and memorable. Unlike in-person shows, virtual attendees can move on at the click of a button, so keep it short and sweet. Trim down your keynote speeches and webinars to make them more sharp and focused. Interaction is key, so be sure there’s some sort of online chat or Q and A function.

At the other end of the spectrum, there’s a plethora of virtual event vendors who offer a wide range of capabilities. The most sophisticated platforms help create the same energy as a physical show, with 360-degree imaging and attendee-controlled avatars that move around the exhibit hall.
When selecting a platform, choose one that can be tailored to your specific needs. For example, is your primary goal to educate your attendees? Then you may want to focus on the “auditorium” section of the platform, where online classes and demonstrations are presented. If, on the other hand, product exhibition is your focus, try to provide multiple capabilities to the vendors—such as live chats with company reps and other attendees, guest speaker-hosted sessions, contact forms for lead capture and reporting, downloadable brochures and videos.
Networking is a key component of any trade show — virtual or otherwise. Which is why many vendors offer a virtual lounge for both standard and video chats.
As a sponsor or exhibitor, you can help facilitate networking by scheduling group chats or posting discussion topics.
Regardless of your approach, it’s best to combine both pre-recorded and live elements for your virtual show. For instance, you can string together pre-recorded clips with live introductions, or provide live break-out sessions following pre-recorded classes.
One final tip: Whichever format you choose, make sure the navigation is simple and easy to follow, to keep from losing your audience.
For Exhibitors and Attendees
Before you participate in a virtual trade show—especially as an exhibitor—you may wish to ask the show’s organizers a few questions, such as:
When was the show first launched? If it’s has been around for several years, it should already have established a following. On the other hand, if the virtual show is fresh out the gates, there would be no data to ascertain its success. But you’ll want to make sure these measures are put into place. (See Question 7, below.)
What is the cost to participate, and what does that include? Most trade show organizers offer exhibitors an online booth for posting videos, white papers and demos. They may also have live chat capability. Above all, make sure there’s a way to capture leads.
What are the show’s beginning and end dates? Typically a virtual show remains open for the same duration as the physical trade show, and then extends 30 to 60 days after the show. So it’s important to know if your participation fee is buying you 10 days or 60 days. Also, check into how long attendees will have access to your online exhibit. You’ll want to be able to update it to keep the information fresh.
How will the show be promoted? Both in-person and virtual shows require a strong promotional strategy in order to be successful. Show producers should use multiple promotional methods to reach previous in-person trade show attendees as well as other members of your target audience.
Is a demo available? Ask the show sponsors for a demo, so you can experience the look and feel of the virtual show just like the attendees and other exhibitors will. Also, if your staff is not familiar with the various virtual show features, will they have access to a tutorial?
Is there an emergency contact? Virtual trade shows require adequate technical support. Make sure you’re provided with contact information in the event of any problem, technical or otherwise.
What tracking and reporting mechanisms will be used? You’ll want detailed information about who attended the show, which booths they visited and for how long, which documents they downloaded, and what questions they asked.
Some Final Tips
When staffing your virtual booth, it’s important to select reps with strong digital communication skills, as well as product knowledge and relationship-building skills. Make sure the reps you choose can express themselves well in electronic communications and are comfortable with video conferencing.
Prospects love to hear from people like them. So make sure your virtual booth allows reps to share testimonials, unique facts and compelling statistics. Your message should cut through the clutter and prompt attendees to stay engaged.

With temperatures dropping across the state, it’s time for irrigation contractors to start making their “winter money” – the cold, hard cash that comes from kicking their winterization programs into high gear.
We’ve compiled a list of best practices to streamline the process and help avoid potential problems.
When to Winterize: Start Early
Ohio First-Freeze
Dates
When does the first freeze of the fall season normally occur in Ohio? Here are the earliest, latest, and average freeze dates:
Plan for winterizations well in advance. Otherwise, you may not have ready access to the equipment you need, such as a commercial-grade air compressor. Remember: Every landscaper in town will be striving to winterize irrigation systems at the same time.
So don’t be left out in the cold. Start scheduling shutdowns with customers and your irrigation technicians as soon as possible. Highest priority should be given to those systems with exposed pumps, piping or backflow devices.
You don’t want to risk potential damage to your customers’ systems by waiting too long. Once December hits, you can expect frozen backflow preventers and exposed pipes. By then, it’s often too cold to do a good job.
The Right Tools to Winterize
Make sure your crews are equipped with the right tools to winterize. Of course, you’ll want to have plenty of standard parts available to make any necessary repairs to the systems. But technicians will also need a commercial air compressor, an air hose, and fittings that properly affix to the backflow device.
The air compressor should provide a minimum of 100 cubic feet per minute, but preferably more, depending on the size of the irrigation system. Smaller compressors, even at 100 psi, cannot deliver the air volume needed to winterize an irrigation system. In fact, 80% of the portable air compressors in use today provide 185 cfm.
If the main shut-off valve is outdoors, you’ll want to use foam insulation tape to protect it (as well as any other above-ground piping) from freezing.
Proper Winterization Techniques
Create a winterization checklist for your technicians to use at each job site. This will prevent them from missing steps and ensure uniformity of service.
The checklist should include the following:
Locate the shut-off valve and turn off the property’s water supply. Check the property’s data sheet for the valve’s location and other specific information, such as faucet zones and pumps.
Turn off any pumps to prevent damage.
Set the compressor for 50-80 psi, to avoid damaging the system. (For drip irrigation systems, set the pressure for 20 or 30 psi.)
Connect to a blowout port, open a zone and then open the air compressor valve. Move most of the water out of the main lines by blowing out the farthest zone first.
Move through the entire system, one zone at a time. Continue blowing air through the lines until only fog is emitted from the sprinkler heads. Do not allow the rotating nozzles to spin too quickly – this can damage the gears. (When they start to spurt, turn them off.)
CAUTION!
The expanding air coming from the air compressor into the irrigation system will get hot and may melt the plastic pipe. Carefully check the temperature of the air hose connection at the blow-out point. Slow down or stop momentarily if it feels too hot! Cycling through each zone two or three times for short intervals will prevent too much heat buildup.
Partially close the ball valves on the backflow preventer, and complete blowing out the last zone.
Turn off the air compressor and allow all the air to exit the system.
Drain the backflow preventer.
Remove submersible pumps from the water. For centrifugal pumps, remove the drain valve and check valve, and disconnect the power supply.
Turn off the irrigation system controller, but leave it plugged in to retain schedules and memory.
Good for Your Business, Good for Your Customers
Proper winterization is not only a lucrative proposition for contractors, it can be a terrific cost savings to customers. Failure to professionally winterize irrigation systems can result in costly issues, such as cracked plumbing, sprinkler heads and backflow devices. Even flexible polyethylene pipe can begin to have random splits if a system is neglected, creating the need for multiple in-ground repairs.
Proper shutdown techniques not only prevent freezing issues in the winter, they also forestall potential water damage once the system is activated in the spring. It’s a win-win for your business and your customers!
Predicted Water Shortages Driving Demand for Greywater Irrigation
Water scarcity is an issue we normally associate with the western United States. But a recent U.S. Forest Service study predicts that Ohio and the rest of the Midwest also will be threatened by significant water shortages in the next few decades.
And the U.S. Government Accountability Office (GAO) expects that all but 10 states will experience shortages as early as 2024.
In such an environment, greywater irrigation systems will become increasingly popular, and perhaps even mandatory for commercial properties.
What Exactly Is Greywater?
Greywater (also spelled “gray water” or “graywater”) is gently used water from washing machines, bathroom sinks, tubs and showers.
The city of San Antonio, Texas, has the nation’s largest direct recycled water system, with a capacity to deliver about 29 million gallons per day of treated recycled water, using more than 130 miles of pipeline.
The name comes from its rather murky appearance, caused by traces of dirt, hair, grease, food and some household cleaning products.
Unlike “blackwater,” greywater has had no contact with any human waste from the toilet, sewer system, or from washing diapers. So while it may look dirty, greywater is a safe – and even beneficial – irrigation source. The same greywater that currently pollutes our lakes and rivers with its trace biomaterials becomes valuable fertilizer to plants.
(Greywater is not potable, however, and should never be consumed by humans or animals.)
Greywater vs. Recycled Water
Greywater is often confused with reclaimed (or recycled) water. And the terms are often used interchangeably. But they are not the same.
Recycled water is sewer water that has been cleaned with chemicals at a sewage treatment plant. It is then delivered to an entire community via purple-colored pipes, and is used primarily to irrigate parks, golf courses and other public areas.
Components of a Greywater System
Greywater irrigation is comprised of three primary stages: collection, storage and use. This can be as simple as a single diverting valve on a home’s washing machine, or a complex system of pumps, filters, storage tanks and pipes. The result is filtered greywater delivered directly to lawns, gardens and other landscaped areas via the property’s irrigation system.
–Article Continues Below–
The most basic greywater system uses a three-way valve to connect a clothes washer with a home’s irrigation system. Another excellent source of greywater is condensate from an air conditioning system, which can produce as much as 20 gallons of water per day. Integrating with a smart irrigation controller ensures water efficiency.
The water may be delivered via driplines or spray heads, but all pipes and fixtures must be purple and designated as greywater conveyors of non-potable water. The water may be used to irrigate ornamental plants, fruit trees and vegetable plants other than root vegetables, but it must not touch any edible portion of the plant.
Benefits of a Greywater System
Greywater
in Ohio
Greywater can be reused and recycled in Ohio with a permit from the local health department (Ohio Code 3701-29-17).
All pipes and fixtures conveying greywater must be purple or marked with a purple stripe and be labeled “Non-potable water, do not drink.”
There are four types of greywater systems permitted in Ohio:
TYPE 1 recycles less than 60 gallons per day. Used for subsurface irrigation of gardens, lawns and landscape plants during the growing season.
TYPE 2 recycles more than 60 gallons per day but less than 1,000 gallons per day. Also used for subsurface irrigation of gardens, lawns and landscape plants during the growing season
TYPE 3 recycles hand-carried gray water that is poured through a screen into a disposal sump tank before discharging into leach field trenches. Commonly used in campgrounds, Amish homes and remote vacation homes.
TYPE 4 recycles treated greywater to be reused year-round outside or inside buildings. Water is stored for no longer than 24 hours before reuse. Outdoors, used for green roofs, living walls, surface and subsurface irrigation of lawns, gardens, and landscape plants. Indoors, used to irrigate houseplants or living walls.
Greywater systems save water and money. Manufacturers of greywater systems state that greywater irrigation can save as homeowners much as 40,000 gallons of water per year. The result is a dramatic decrease in water bills, especially during the summer months. According to Saniflo spokesman Chris Peterson, “Homeowners who begin recycling greywater now could be well ahead of the curve if and when their states begin requiring water conservation measures.”
Greywater systems prolong the lives of septic tanksbecause the amount of water being deposited into the system is greatly reduced.
Most ornamental plants find greywater to be more beneficial than tap water.Greywater contains residues, such as nitrogen, which many plants can use for food. Roses, bougainvilleas and honeysuckle particularly benefit from greywater irrigation. In addition, slightly soapy water will percolate more deeply into the soil, preventing runoff.
What It Means for Irrigation Contractors
The experts at Rain Bird believe that many (if not most) of new commercial building projects will soon require greywater or some other water-harvesting system be integrated into their landscape irrigation designs. (Hunter Industries currently uses greywater irrigation at all of its operational sites.)
In other words, irrigation professionals who haven’t yet designed and installed these systems will do so in the near future.
Are Your Customers Still Using Standard Irrigation Timers?
Smart technology may be everywhere, but irrigation contractors know that standard, old-school irrigation timers are still very much out there.
These basic clock timers are still being manufactured, installed and maintained—so they’re not going anywhere soon. According to Rick Arena, a training manager at SiteOne in North Carolina, “Probably 75% or more of all controllers sold right now are still the old style.”
And while they’re not capable of making any complicated decisions, for certain applications, these “old timers” are actually better suited.
How to Get Smarter
Just about every “dumb” irrigation controller made in the last decade or two includes sensor terminals for connecting to a rain or soil-moisture sensor.
Numerous add-on devices are available, such as:
Hunter’s Rain-Clik, Mini-Clik, Freeze-Clik, Soil-Clik and Mini-Weather Station devices, which will work with virtually any controller.
Rain Bird offers a LNK Wi-Fi module for weather-based water management, which can be plugged into any of their ESP-TM2 and ESP-Me Series controllers that were manufactured after Nov. 2, 2016. For Rain Bird controllers made before that date, a Wi-Fi-compatible replacement panel can be installed.
ETwater from Jain offers a retrofit smart controller which can be attached in less than 10 minutes and is compatible with all irrigation controller brands.
Keep It Coming
A perfect example is a new lawn, whether sod or seed. With standard irrigation timers, the water is applied at regular intervals with no exceptions. Which is what you want with new turf: frequent, short bursts of water for at least 30 days, until the grass takes root.
In fact, standard timers are often installed (at least temporarily) to maintain curb appeal for newly built homes.
Paradign Shift
Another reason standard timers are still in demand is their simplicity. As it turns out, not every homeowner wants an irrigation controller that uses ET data, local weather forecasts or various sensors for its watering schedule.
Rain Bird product manager James Harris explains it this way: “New technology like smart controllers always has an adoption curve, and not everyone is ready to adopt it at the same time.”
Particularly for some older homeowners, a smart controller may as well be speaking a foreign language. They can be baffled by all the settings. And they’re not interested in investing their time learning to set up and use the latest technology. Millennials, on the other hand, naturally gravitate toward and embrace technological advances. As this younger demographic continue to purchase homes, the demand for smart controllers will likely increase.
–Article Continues Below–
This required paradigm shift applies to contractors, as well. Ramzi White is a SiteOne key account manager in Texas. He says the standard Hunter or Rain Bird clock timers are still his best sellers. In fact, many contractors in his area don’t really even know what a smart controller is.
Know Your Customer
As an irrigation contractor, the decision to offer smart technology to your clientele often comes down to knowing the customer. A 70-year-old who’s just learning how to email and text is probably not a good prospect for a smart controller. Some younger people may also prefer to have fewer bells and whistles.
But generally speaking, homeowners in their mid-40s or younger, who’ve essentially grown up with technology, enjoy integrating new gadgets into their homes. For them, smart controllers can be a very easy sell.
Since July is Smart Irrigation Month, let’s explore one of the most effective means of conserving water in a landscape: drip irrigation.
A drip system may not be the first thing most people envision when they think of landscape irrigation. But these highly efficient systems not only conserve water, they also can irrigate slopes and oddly shaped areas with precision.
Drip Irrigation Basics
Drought in Ohio
Since 2000, the longest duration of drought in Ohio lasted 44 weeks beginning on July 23, 2002, and ending on May 20, 2003. Drought conditions ranged from “moderate” to “exceptional” during this period.
On the other hand, the most intense period of drought occurred during the week of September 4, 2007, when “extreme” drought affected more than 11 percent of the state’s land.
Drip irrigation slowly and steadily delivers gallons of water per hour, as opposed to gallons of water per minute like sprinkler systems. And because the water is directed to the plants’ roots, runoff and evaporation are minimized. So less water is required.
A drip irrigation system consists of the following basic components:
Water valve
Backflow preventer
Pressure regulator
Filter
Tubing adapter
Dripline (PVC or polyethylene tubing)
Emitters
Electronic controller
Once the basic system is installed, any number of lateral lines can then be attached through various headers. Each line is fitted with water-dispersing emitters, and then can either be buried or covered with mulch.

When it comes to the dripline, contractors have two options: Insert the emitters anywhere you wish along the line, or purchase lines with pre-inserted emitters at regular intervals.
However, choosing the correct emitter is important. Output rates for emitters vary from a half gallon to two gallons per hour. Emitters with different output rates may be installed on a single dripline. This comes in handy if you need to irrigate plants with distinct watering needs that are located close together.
Adjustable emitters are also available. These allow you to regulate the water flow rate, from a steady drip to a slow stream.
Drip System Applications
Drip systems are primarily used to water flower beds, gardens and particularly small or unique landscape areas. They’re perfect for xeriscape-type gardening which requires limited irrigation.
Adobe Image, License Granted
But they can also be used to provide supplemental irrigation. For instance, drip irrigation can be added to bedding areas that are already incorporated into sprinkler zones.
In addition, drip systems can be used to irrigate larger areas, such as both new and already-established lawns. For a new lawn, simply install the dripline before sodding or planting grass seed. With an established lawn, the drip line is trenched into the turf.
Maintenance
Typically, drip systems are easier to maintain than sprinkler systems, because the emitters and dripline aren’t deeply buried. The trick is in determining when a repair is needed. Whereas a broken sprinkler head is easily identified, with a drip system, you must look for browning or wilting vegetation.
Which is why you’ll want to incorporate a flow meter in the system. This sensor will notify the controller of any flow irregularities. An alert is then sent to the home owner’s smartphone. Wireless flow meters are both affordable and easy to install.
Selling Points
Drip irrigation systems offer numerous benefits your customers should know about:
Better plant health. Water penetrates slowly and deeply into the soil, placing moisture exactly where it’s needed – at the roots. Plants grow quickly when they are watered uniformly without stress created by lack of water.
Less waste. A good drip irrigation directs 90 percent of the water into the soil, with very little lost to evaporation.
Environmental benefits. Because drip irrigations are so effective, there is less chance of erosion, with very little runoff ending up in area streams and rivers.
Reduced risk of disease. Drip irrigation keeps the foliage dry, thus reducing the incidence of powdery mildew and other diseases that occur in damp conditions.
Weed control. Drip irrigation systems place water directly around the plant. As a result, weed seeds are water starved and germination is limited.
Like sprinkler systems, drip irrigation requires winterization. Be careful, however, that you don’t use too much air pressure when blowing out the lines. (You don’t want the emitters to pop off.) It’s also a good idea to store the backflow preventer and irrigation controller indoors for the winter.
For spring start-ups, be sure to inspect all components for cracks and splits that can occur in very cold weather.
Expanding Market
If climate experts are correct, drier days are ahead for most of the country. Which is one reason drip irrigation has become increasingly popular over the last decade.
At times of severe water restrictions, homeowners with drip systems are often allowed to irrigate several more days per week because of the greater efficiency of these systems. (In fact, these customers may be exempt from watering restrictions altogether.)
And although properly installed drip systems are typically more expensive that sprinkler systems, that initial expense is offset by the cost of water savings over time.
Drip irrigation may not represent a total change of direction for landscape irrigation contractors. But it does nevertheless represent an expanding market and is well worth adding to your menu of services.
Market Your Business as a Leader During Smart Irrigation Month
July is Smart Irrigation Month. Are you geared up to market your company as a leader in water-saving practices?
It was 16 years ago that the national Irrigation Association (IA) first utilized the month of July to promote the social, economic and environmental benefits of efficient landscape irrigation. And every year, Smart Irrigation Month has gotten bigger and better.
New Tools
Again this year, the IA has added some new tools to help irrigation contractors market smart irrigation throughout the month of July. Such as:
Encourage sales and marketing staff to participate in dealer and distributor Smart Irrigation Month activities.
Host a live demonstration of water-saving irrigation technologies in the field or at your location.
Feature water-efficient products and services in displays, ads, promotions and product demos with the Smart Irrigation Month logo.
Make smart irrigation the theme of sales calls.
Distribute awards to customers and/or business partners who promote water-efficient practices.
2019 Video Contest Winner
Also included in IA’s July promotion is the smart irrigation video contest. Last year’s contest winner was Florida-based NatureScape Irrigation Service. Take a look:
Residential areas, farms, forests, small towns, big cities …They’re all part of a massive watershed network. Watersheds cross municipal, county, state and even international borders.

They come in all shapes and sizes, encompassing millions of square miles or just a few acres. And like creeks that drain into rivers, small watersheds are almost always part of a larger watershed.
For instance, Ohio’s 23 major watersheds consist of 254 principal streams and rivers. But they all drain into either Lake Erie or the Ohio River. (See “Ohio’s Two Primary Watersheds,” below.)
Our landscape and all its activities interconnect with streams, lakes and rivers through their watersheds. Naturally varying lake levels, water movement to and from groundwater, and amount of stream flow influences them as well. The health of our waterways is largely determined by these dynamics between the land and the water.
Ohio’s Two Primary Watersheds
In Ohio, rivers north of the Continental Divide flow to Lake Erie and the St. Lawrence Seaway. Rivers south of the Divide flow to the Ohio River and, eventually, the Gulf of Mexico.

Becoming Watershed Wise
Watersheds must be protected if they are to sustain life. When human activities alter the natural function of the watershed, residents can be adversely affected by frequent flooding and routine periods of drought.
The three leading causes of polluted waterways are:
Sediments
Bacteria (such as E. coli), and
Excess nutrients (such as nitrogen- and phosphate-based fertilizers).
Watershed-wise practices help create a balance and allow nature to work in our favor. When properly employed, residential landscapes can function as healthy mini-watersheds. The Green Gardens Group (G3) provides training and certification for its Watershed Approach to landscaping. This approach includes four key elements:
Build Healthy Soil
Capture Rainwater
Select Native, Climate-Appropriate Plants
Use Highly Efficient Irrigation
Smart irrigation technology (smart controllers, rain and soil-moisture sensors, and pressure regulators) is a key component of this approach and ensures optimal irrigation system performance.
Best Practices
As an irrigation and landscape professional, are you practicing watershed-wise principles, or are you contributing to the problem? Here are a few tips:
Promote smart irrigation controllers and other technology with your customers, to ensure that runoff is reduced or even eliminated.
Utilize matched precipitation rate (MPR) nozzles.
Suggest that your customers create hydrozones (groups of plants with similar water needs) to conserve water.
Offer your customers natural alternatives to nitrogen- or phosphate-based fertilizers? And suggest integrated pest management instead of pesticides.
Make sure that roof runoff is directed onto a grassy area, not a sanitary or storm sewer system.
Suggest porous surfaces for landscaping (such as flagstone, gravel or interlocking pavers), rather than impervious surfaces like concrete.
Consider installing irrigation systems that draw from rainwater or gray water, whenever possible.
Remind your customers that irrigation system management is critical! Systems must be actively and constantly managed in order to be watershed wise.
Take a Virtual Tour of
Ohio Watersheds
The Ohio Watershed Network offers a virtual tour of Ohio’s watersheds, beginning with the smallest streams in the watershed, the Headwaters.
From there, they move through the wider, slower-moving creeks and floodplains of the Middle Reaches. Then to the lakes, ponds and reservoirs, where sediments and many contaminants can collect.
The next stop is the precious Wetlands, with its large variety of plant and animal life. Finally, the last stop on the watershed tour is the Mighty River, where sediments, debris, or contaminants empty into the receiving waters.
We all affect the watershed, one way or another. Whether our individual influence is positive or negative is up to us.
A Discussion of How Ohio’s Irrigation Contractors are Responding to the Coronavirus
Jerrad Lee, President of the Ohio Irrigation Association, conducts a round table discussion of landscape irrigation contractors’ response and experience with the coronavirus pandemic. Jerrad reviews the current best practices for shelter-in-place, essential business services, and the CARES Act.
Webinar Transcript
Tom Barrett, Ohio Irrigation Association:
Good afternoon everyone. My name is Tom Barrett and we’re pleased to have you join us in this discussion of how the irrigation contractors are handling the coronavirus and the CARES Act. Presenting for us today is Jerrad Lee, president of the Ohio Irrigation Association. He has 10 years of experience in the landscape industry. Currently, he’s the irrigation services manager for Environmental Management. We anticipate this to be a discussion because we’re all learning here. And so if you have a question, raise your hand and I’ll unmute you or you can type a question in the chat box down at the bottom. So please don’t hold back because, like I said, we’re all learning here. Jerrad.
Jerrad Lee, Ohio Irrigation Association:
Good afternoon, everybody. Can you hear me all right?
Tom Barrett, Ohio Irrigation Association:
You sound great.
Jerrad Lee, Ohio Irrigation Association:
Perfect. My video is not working, but it’s okay. So I wanted to start off by saying thank you to everybody for taking time off on your Friday to join us on this. My goal here, as Tom was saying, is for us to come together as an industry, both distributors and contractors, landscapers, irrigation guys all alike, to come together to figure out exactly the best way to keep our team safe, keep us safe, and keep our businesses rolling as usual. So some of the stuff that I am going to be talking through today, as you can see, is the Covid-19 stuff, obviously. But I really want to go into what you guys are seeing out there, what you’ve experienced, that people weren’t stopping you, that kind of stuff as well as talking about the CARES Act and how it can apply to us.
I’ve got several key points that I want to talk about today, as well as the emergency funds that we can use for our businesses, as well. Kind of the start off, if you’re not confused, you’re not paying attention. So everything that we are going to talk about today, it’s ever changing. It’s changed. About five minutes ago, Tom and I were on a another conference call to learn about some updates to what we’re going to talk about today. And it wouldn’t surprise me if tomorrow it changes again. There you go. Everything’s subject to change. It’s been changing on a daily basis. What I want to talk mostly about is making sure we’re following our shelter in place and we’re keeping ourselves safe, whether that’s with PPE and so on. But here in Ohio, we are not necessarily viewed as “essential.” It’s definitely on a local level as different requirements as to who can and can’t work.
In Pennsylvania , landscapers are not considered essential. So I want to make sure you were aware of that. Ohio, Michigan, Kentucky, West Virginia, we’re allowed to work. But again, it depends on where in the state you are. Some cities won’t let you work and some will. That being said, I’d kind of like to start off with just some input of around the state. So I’m in Columbus. I’d love to get someone from Columbus, someone from Cleveland and someone from Cincinnati to kind of tell us what you guys are seeing out there. Okay? So I’ve heard stories… I believe I was told just today that people in Knox county are getting fines for working. In Columbus, we are working as usual.
Tom Barrett, Ohio Irrigation Association:
Jerrad?
Jerrad Lee, Ohio Irrigation Association:
Yes, sir.
Tom Barrett, Ohio Irrigation Association:
Greg wants to say something. Greg, you’re permitted to talk. I think if you push the space bar, you can talk.
Greg Davis, Environmental Management:
So one thing that we did, we’ve installed a Covid plan pretty early, but we were subject to a a health inspection just last week. There was a random observation of maybe too many folks in a truck. They did stop in and we had our plan together. We showed him everything that we were doing and it was a pretty quick and painless investigation. He liked everything we were doing. But the point is, we had something, we had a plan. We showed them everything we were doing. That causes him to see that we were doing everything we could to stick to the local requirements at that time. Like you were saying, Jerrad, it’s just changing. It seems like hourly. So I mean that’s kind of what we’re doing here. And he reacted to one complaint, so anyone can get a complaint at any time. And he said it was just a random passer-by who just all saw some guys in the truck.
Tom Barrett, Ohio Irrigation Association:
So Greg, did you have something in writing with you?
Greg Davis, Environmental Management:
Oh yeah, he came to our office. And even the week prior, as soon as this started, we had a Covid plan in writing. It’s everything that the employees are supposed to do. It’s a contingency plan for every employee. Like every management play in case they get sick. It runs down who’s going to do what, who’s going to take over and what cross-training they need to get up to speed. We found a camp full of gaps there, especially in like billing and and AR and AP and things like that. But yeah, we had a written plan and we shared it with him. He wasn’t really interested in seeing the actual details. He was more interested in the fact that we had it. You know, when he came in, he was asked the three questions we had to ask every person because we don’t have thermometers yet. And so I think that set him at ease as well.
Nobody from Cleveland is on. This is Scott Knowles. It was in the papers up there, but Impullitti Landscaping had an unannounced stop-by from their local officials. Who I guess said that they were just doing that randomly, seeing who’s open and stopping in to see if they were taking all the precautions for social distancing. In Plenty did. And they had again, like a plan and they had all the stuff in place, you know, the wipes and sprays and people distancing. A couple of the folks, I guess in the office, working from home, and the officials gave them an “all clear,” and congratulated them on doing their job and thanking them for that. So that’s something that you hear more of now, our local officials stopping job sites or offices and questioning. In most cases, just questioning, are they doing what they need to do? So a little feedback there.
Tom Barrett, Ohio Irrigation Association:
Yeah. Thank you. I’ve also heard that in the state of Ohio, the fine could be up to $750 and 90 days in jail. And I’m not sure how true that is, but I have heard that.
Scott Knowles, Wolf Creek Company:
I have not heard the 90 days in jail, but various localities will have fines for second offenses up to, the highest I heard was $1500. And I think that might’ve been Pittsburgh.
Tom Barrett, Ohio Irrigation Association:
Yeah, I think that’s an interesting point. It can vary from locality and county, and it can be more stringent than the state of Ohio. And the state of Ohio appears to have left it a little bit vague, whereas other states have said specifically landscaping is permitted or not permitted. In Ohio it doesn’t specifically point out landscaping.
Joe Twardzik, Wolf Creek Company:
Yeah. Tom. This is Joe Twardzik. Yes. You’re absolutely right. The the local jurisdictions are interpreting as they see fit. The $1500 fine that Scott was referring to, I heard that was actually Montgomery County, which is Dayton. And Scott pointed out about Impullitti, that was actually at their office. So they can walk out and then a previous person talked about getting stopped out and about in the truck. But they can stop in your office, do the same thing. It really is about having a plan in place and actually following the guidelines. So if you do both those things, you’re actually doing, not just writing it down, but walking the walk and talking the talk, that means everything.
Jerrad Lee, Ohio Irrigation Association:
Yeah. And what we did too, to build on what you guys are saying is, we make sure our guys have the key talking points. So my irrigation techs know that they’re protecting a natural resource of water. So that’s along with the landscaping side of things, of keeping a well-maintained landscape. Kind of like the broken glass theory where, if you see one broken window in a house, you’re going to eventually see more. The crime’s gonna start growing. So we’re making sure within this paperwork that they have those key talking points so they know exactly the why’s, they can explain it to themselves. And if you watch John Houston, the lieutenant governor, he will say even that it was all vague, and it’s up to interpretation to the contractor. And the authorities aren’t necessarily going to interpret it. It’s kind of goes back to the way we interpret it, and how we’re doing and how we can advertise what we’re doing and why. So that’s why those key points are essential to have.
Tom Barrett, Ohio Irrigation Association:
We just had several people join us. What we’re talking about here is anybody that’s seen restrictions or anybody that’s been cited with the shelter in place. And in order to participate just press the space bar on your computer and you can talk.
Jerrad Lee, Ohio Irrigation Association:
All right, so kind of moving on. Some of the things that I want to make sure we’re kind of doing. This is some of the best practices that I think we should be following, such as asking for permission. I know when it comes to my tax, we’re not just going to a site even it’s for an outdoor backflow. We want to make sure we’re allowed on that site and what their guidelines are. Maintaining a safe distance. So if we’re going inside of the building, we’re calling ahead. After we get the permission, but we’re still calling ahead, so we can get doors unlocked or a clear path from the outside of the building to where our back floor controller is.
The crew members are using personal vehicles. That’s a great one to keep an eye on. We keep the social distancing. I’m still seeing trucks with five or six guys in them driving down the road. Obviously, some people can’t drive. They may not have a driver’s license or what have you. But doing the best that you can. Kind of going back to what Tom was saying, the local ordinances may be more restrictive, depending on where you are. So even on the national level, out in California, there’s some towns where you can’t be working at all. You get fines, just like Joe and Scott were talking about, in some areas in California you’re fined. And that’s the same thing here. Any more information that you might need? Our website has some guidelines to follow. Feel free to take a look at it. But I know with PPE that I’m seeing guys use, it’s great to see that the people are out there with face mask and gloves and all that stuff.
But what I’m seeing a lot in my experience, watching crews work and different teams work, both within my organization and with another, are people wearing gloves. And that’s great, but they’re cross contaminating everything they touch. So they go out and they may shake someone’s hand or they touch something that could be infected. And then you’re watching them, they’re touching their phone, they’re scratching their face and touching their steering wheel, and then they’re not cleaning the steering wheel off afterwards. So it’s great that they’re having the gloves on, but if that stuff stays on it, then they’re just contaminating everything else as if they weren’t having it. So I’m always making sure my guys have what PP they have and hopefully give them some extra, so they can change their gloves.
Tom Barrett, Ohio Irrigation Association:
And I think it’s important to note this could change tomorrow. In New York, one of my clients is a contractor. On Saturday, a week ago, Cuomo announced that they would restrict all construction except for very essential construction. So the best place for current information is on the website. Anybody hears anything, let us know. We’ll put it up on the website. We want to keep the website as current as possible.
Jerrad Lee, Ohio Irrigation Association:
To kind of go into the CARES Act, is the $8.3 billion Economic Injury Disaster Loan, which we’ll go into in a second. The Paycheck Protection Plan is actually Phase Three. It’s HR bill 748. It’s a $2 trillion stimulus package, which is the biggest package that I think we’ve seen in our lifetimes. So as of a week and a half ago, I was on a conference call and some of the stuff that we learned then has already changed to now. So a week and a half ago, it started off at $349 billion is in this fund. It is now being increased by $250 billion, which makes it $600 billion all in. These funds will be disbursed basically over an eight-week period. So this is built on a 78 program through your SBA. So Tom, if I misspeak on anything, please don’t hesitate to interject.
Tom Barrett, Ohio Irrigation Association:
Yes. So what I’m hearing, there’s about 15 companies that I’ve worked with that have applied for this. The Paycheck Protection Program is designed to maintain your employees so that, when work becomes more normal, you don’t have to hire new employees. A lot of people have the misunderstanding that this is a way to help reduce the unemployment rate and unemployment benefits. But actually this is more expensive than the unemployment program that was passed. I think one of the most important things to note is, any employee whose primary residence is not in the United States does not get anything in this plan, nor do you have to include them in your payroll calculations.
The payroll calculations can be done in two different ways. And this just recently changed. I just learned of this less than an hour ago. You can use the 12-month prior number for your average monthly payroll, or you can use from 2/15 to 6/30 for seasonal workers. So there’s a couple of different ways to do it. I don’t think there’s one best way to do in the landscape industry. I would suggest you figure it out both ways. You can then receive two and a half months of your payroll, and 75% of that must be used for payroll. And if you do that over the eight-week period, which starts on the day you receive the funds, this is completely forgiven. So it becomes a grant. It’s a really nice program. It’s administered through the local banks and it’s all over the board what you may need in order to apply for the loans. So it’s up to the individual lending institution how they want to document the loans. I’ve had some people have to provide taxes, others just basically had to provide a P and L. And it’s really up to the bank because they are administering it.
Don’t give up if you haven’t seen the funds. I’ve just started to see the funds distributed this week. So I’ve had one account that applied at like 1:45 on Saturday morning; they received approval by 8:00 that morning. They received their funds on Tuesday. On the other accounts. I’m starting to see approvals come through and it feels like they’re going to get their funds all at once in about three days. Some of the banks I’ve heard are distributing the funds in a lump basis, and others are distributing it out in increments. So we’re really not sure where that is. Any of you have any experience with these funds?
Jerrad Lee, Ohio Irrigation Association:
So one thing to point out if nobody has anything is, as of today, independent contractors and self-employed individuals can apply for this. There’s a little bit of a caveat to that I learned just yesterday listening to Mike DeWine’s speech. As of right now, in the federal government or in the states there is not a way for an owner of a company to apply for this as of yet. What they need to do is, each state is working to develop their own program to get the owners and sole proprietors of a business to be able to apply for these kinds of loans or this kind of money. So there could be a delay here in Ohio. In fact, there’s going to be a delay because, like I said, they don’t have it set up yet. They’re working on it right now. And each state is going to be different. So for those of you who work in different states, just know it’ll be different depending on where you go and how they set it up. But that is coming. And just like anything else, be prepared. It could be inundated with phone calls, emails and everything else. And that’s pretty much what’s happening, especially in the unemployment offices and everything else.
Tom Barrett, Ohio Irrigation Association:
So that’s a good point, Jerrad. There is starting to become available local, county and state funds. I know the city of Chicago has an emergency relief fund that they’ve established. A couple of counties in Colorado that I’m working with have established emergency relief funds. DeWine yesterday said they were going to establish an emergency relief fund in the state of Ohio. All of this is brand new. None of us really know for sure what’s going on. So as you hear things, let us know. And then the website down there we’ll continue to keep that updated as more information becomes available.
Does anybody have any questions or anything they can add to their experience with the Paycheck Protection Program? Doesn’t sound like it. So again, if you need to talk, press the space bar and you can talk. This is a really good program. I would encourage everybody to apply for it, if they haven’t already. And it looks like the $250 billion in additional funding has not been approved yet, but it feels like it will be approved by next week.
Jerrad Lee, Ohio Irrigation Association:
Before we move on. Just so we are aware of unemployment information, again watching Mike DeWine yesterday. So far as of yesterday, there’s been 696,519 Ohioans have lost their jobs over the past three weeks. That number is twice as many as all of 2019. So, and that’s just in three weeks. So as of right now, 207,000 of those people have that check sent to them, totalling about $132 million. So obviously, the unemployment offices are behind on things, as is everybody with this because nobody was prepared for it. Gov. DeWine is talking about expanding and adding a thousand people to help get these moved through, and they’re going to expedite the approval process to get this taken care of. That’s all I had left on that.
So kind of moving into the EDIL loan, the Economic Injury Disaster Loan. So this is a loan that is not forgivable. There will be a payment back to the government for these loans, but they are for less than 500 employees. I believe just today we learned that they are starting to add this to Main Street type companies. I’m not sure if that goes to anybody in here, possibly the distributors, but the Main Street. I’m trying to find my notes. Like I said, it’s brand new to me.
Tom Barrett, Ohio Irrigation Association:
So the Main Street or any company that has over 500 employees. And then there’s an affiliation rule that applies depending upon how your corporation is set up. So for the larger corporations that may have subsidiaries, you may or may not have to qualify all of the employees from all the subsidiaries. It just depends on who has controlling interest.
Jerrad Lee, Ohio Irrigation Association:
Thank you, Tom. So as we go through here, maximum loan is $2 million and the maximum term is 30 years. So the your term is going to fluctuate, depending on the size of your business and some other key factors there. I believe the interest rate was going to be about a half a percent and it’s now 1% payback.
Tom Barrett, Ohio Irrigation Association:
Jerrad, it’s a 1% maximum on the paycheck protection. That’s what we’re hearing. And this loan here is 3.75. So the EDIL loan is 3.75. The payback term and the amount of the loan is going to vary, based upon your financial statement and the SBAs rules. And the SBA is keeping it rather quiet, how much is going to be distributed. There is a $10,000 disbursement that could be used for payroll, but it can’t be used for payroll during the same time period as the paycheck protection. So that we just learned today. And like Jerrad said, this has to be paid back. There is no forgiveness on this at this point.
Jerrad Lee, Ohio Irrigation Association:
They are saying you could definitely apply for both. And they are encouraging you to apply for this, if you think you’re going to need it. But if you don’t need it, you won’t have to take it. But they’re saying to at least apply for it to get the process started, if you think you will need it. So again, more information on this can be found on our website, if you have questions. So again, just to kind of reiterate, everything’s up to change.
I think everybody in Ohio is doing an awesome job, and that’s kind of what I wanted to go into next is, what is happening in Ohio? And kind of why are we where we are, as far as what’s going to happen going forward? So if you if you watched DeWine’s speech yesterday here, there was a bunch of protesters outside the state house, and that’s all good and well. And there’s a lot of questions to the governor as to when is this going to end? The reason why I bring this up is, I believe it was Singapore that was starting to hit their peak, and they were starting to come down on things. So once the numbers started going down, they eased up and let social distancing come back and opening more things up. Once they did that, they noticed that they had a spike, and I believe it went higher than where they plateaued when they were fighting through it. So more of the story is, the reporters at yesterday’s conference were asking, when is this going to happen? Is going to be May 1st? And the governor said, it’s all up in the air right now.
Nobody truly knows when this could end. It could be four weeks, it could be eight. That being said, just make sure we keep working together to keep this going. That’s why I wanted to have this conference call, so we can work together as an industry and not individual companies aside, and we don’t make it anywhere. So as far as other things that are happening in Ohio, these are wins, if you ask me. There’s 19 manufacturers that are partnering with three hospital groups around the state. And what they are doing is manufacturing face shields that can be sanitized and reused at the hospital. The manufacturers they went to were manufacturers of toys, of car parts. They are plastic injectors or die-cast makers. These are people who have not manufactured any kind of health care stuff, but now they are.
So it kind of goes back to the world wars when they were transitioning manufacturing back then. But this is all happening in Ohio. The other thing is, obviously, Battelle is starting to sanitize the N95 masks. If you guys are using N95, obviously, we have a shortage of those. The governor is urging, please, please don’t throw those away. They can be sanitized up to 20 times at Battelle here in Columbus. I know their corporate is here in Columbus. I’m not sure when the drop-off location is. I’ll have to get back to you on that. But moral of that story is, don’t throw those away. Save them. Every one that’s thrown away is one less mask out there for somebody else to use. Again, they can be used 20 times.
That’s all I really have and all that good stuff. But if you guys have other stories, I’d love to hear them. I know we’re getting through this today. Please reach out to me. Here, let me get my contact information up. Here’s my phone number and my email address. So if you guys are seeing some things out there in different counties. The distributors especially, or people outside of Columbus. I’m in Columbus, so I kind of have an idea of what’s going on. But really anybody, I’d love to get your input of what you’re seeing.
The Ohio IA is also working with the national IA on different things. And the more input we get, the better off we are, to go to the state house to help defend us. So obviously with the 600,000 people now out of work here in Ohio, I think our work is not necessarily a right right now. It’s a privilege. We’re not part of the statistic, but it could happen at any day as the economy turns downwards. So I would just encourage everybody to stay safe. As I’ve said in my emails and on LinkedIn, we’re in this together and we need to get through this together, and I know we will get through it together. It’s just going to take time. We’re not at the end yet, and the governor is saying that every day.
Tom Barrett, Ohio Irrigation Association:
Anybody have any other questions? Again, push down on your space bar. You can speak or you can type a question into the chat window.
Joe Twardzik, Wolf Creek Company:
Tom and Jerrad. This is Joe from Wolf Creek. I just want to know if there’s anybody having any instances where they’ve run into problems, or they have solutions. Just something they can share with everybody because we are as, as you guys said, we’re in this together. So just reasons to keep working. Just any challenges you see out there.
Eric Klopfer, Environmental Management:
This is Eric with EMI. We’ve run into a couple of challenges if you don’t mind me sharing. Not really challenges, I guess, per se, but “what if” situations. If an employee comes to you and says they’ve been around someone, what do you do? And I know we’ve got all the paperwork that tells everything, but a lot of times it’s hard to make that decision, right? Whether they could be infected or not, or should they be working or not. So there’s been a lot. And really the best thing I can say is, don’t take anything lightly.
We had an employee at one point that had strep throat, got tested positive for strep throat, went home, stayed home for six days or whatever. Then went back in to the doctor because he wasn’t feeling well, got tested and tested positive. So what is one thing could turn into another thing. I would say just don’t take anything lightly. We’ve had a lot of instances where people are just hey man, they’re just afraid to come to work for a while. We’ve got to be real on that, right? We’ve got to be sympathetic to it. And you’re going to have people that probably are going to try to take advantage of this, and stay home and do other things and just take it as a vacation. That’s difficult too. But at the end of the day, if somebody’s coming to you with something, you’ve got to respond the right way. It’s got to be, “Hey, employees first at this point,” and you’ve got to take everything seriously. Like they could be infected. So that’s the only piece I had. I just wanted to say we do have to take it seriously anytime anybody comes to us with any type of complaint.
Tom Barrett, Ohio Irrigation Association:
Yeah, that’s a really good point. We have a responsibility for our employees, and every one of us has a different perspective on this. It’s important to be understanding and additionally not to have others infect others. The face mask is the best thing that we can use right now. So good. Thank you so much.
Anybody else want to add anything? Jerrad, thank you very much for your time and all the work that’s going into this. Everybody on the call, thank you so much for your participation. We will have another webinar as information becomes available. We hope you found this informative. Again, check the website for current information or call Jerrad or myself, if you have any additional information. Have a great day and a great weekend.
Matched Precipitation Rates Prevent
Runoff and Dry Spots
As an irrigation professional, you know how important water efficiency has become to the industry.
Gone are the days of sprinkler run-off overflowing into the street. With today’s technology — smart controllers, rotary nozzles, soil moisture sensors, etc. — the irrigation industry is using water much more efficiently than ever before.
And one key to that water efficiency is matched precipitation.
The Basics
When designing sprinkler systems, matching precipitation rates can help to avoid wet and dry spots, as well as excessive run times. Which is why irrigation system designers must consider flow rates and arcs of coverage to ensure even precipitation for each coverage area or zone.
Pixabay Image
Flow rates are proportional to the degree of arc covered. For example, the flow rate of a quarter-circle (90⁰) sprinkler head is equal to one-quarter that of a full-circle (360⁰) head. Likewise, the flow rate of a half-circle (180⁰) spray is equal to one-half that of a full circle.
Matched precipitation rate can be achieved two ways:
By zoning together sprinklers with the same precipitation rate (Gallons Per Minute x 96.3 ÷ area), or
By selecting the appropriate Matched Precipitation Rate (MPR) nozzles.
When heads without matched precipitation rates are used in the same zone, dry spots often develop. This can lead to the extension of sprinkler run times, as the entire area is watered longer to keep the dry spot alive. That’s why it’s important to always zone together sprinkler heads with the same precipitation rate.
This can be achieved by matching the gallons per minute (GPM) of a standard rotor to its arc and reducing the range accordingly. For example, two GPM at 90⁰ would equal four GPM at 180⁰, or eight GPM if the sprinkler head covers a full circle.
An Illustration
The Hunter Industries website offers the following illustration of three different sprinkler heads with matched precipitation rates:
Hunter Industries Image
For each of these sprinkler heads, one GPM is applied to each quarter circle (assuming the throw radius is the same for each head). As a result, precipitation is matched.
On the other hand, if you were to install nozzles with the same flow rate on all three heads, areas covered by the 90⁰ head would receive four times as much water as the area covered by the full-circle head. So the quarter-circle area would flood long before areas covered by the 360⁰ head received sufficient water.
(For detailed examples of how this works, click here.)
MPR Nozzles

Matched Precipitation Rate (MPR) nozzles provide a much simpler way to match precipitation rates within the respective irrigation zones. These nozzles allow sprinklers with various arcs and radii to be mixed on the same circuit. They work well, for example, with beds or turf areas that are irregularly shaped and therefore require varying radii of sprinkler heads within the same zone.
MPR nozzles offer irrigation contractors and technicians greater flexibility when working on the system. Different nozzles can be used for precise watering, while still maintaining matched precipitation rates across the irrigation zone.
Can You Mix and Still Match?
So can different types of sprinklers be used within the same zones? According to Brent Barkley, product manager for Rain Bird in Azusa, Calif., the answer is “Yes, but cautiously.”
“With careful design, and the right products, it is possible to match the precipitation rates of rotors and rotary nozzles, allowing them to be zoned together while irrigating different sections of an irregularly shaped lawn,” said Barkley. An example would be if rotors are being used on a fairly large area of turf in a front lawn, you could probably utilize some rotary nozzles to irrigate a narrow strip of side yard.
What you want to avoid, however, is a hodgepodge (“crazy quilt”) of sprinkler types with no apparent rhyme or reason. A situation like that can result when numerous repairs and alterations are performed by various contractors over the years.
Particularly on older systems, you may see the crazy quilt layout, with a combination of spray heads and rotors delivering water at much different precipitation rates. In such a situation, replacing the spray heads with rotary nozzles can help come very close to achieving matched precipitation rates without replacing the whole system.
