This Water Is Just Right: HOAs Strive For Green Fields And Conservation
Jose Alvarez, a supervisor at R. H. Dupper Landscaping, stood up from changing a sprinkler nozzle on a large grassy field at a homeowner’s association in Chandler, Arizona. He surveyed the turf, a patchwork of green and brown.
“It looks terrible,” he said. “The sprinklers, they don’t have enough pressure, and they spray, like, a little bit.” He noted the rings, like miniature crop circles, created by uneven watering.
Josh Dupper said they get a lot of business fixing this kind of problem.
“Their water bills were through the roof because they were essentially flood irrigating,” Dupper said. “It still looked bad, even while they were spending a ton on water. And their landscaper just did not know what to do.”
Revamping the irrigation plan is the first step. Dupper’s company uses historical evapotranspiration data and homemade software to determine how much a field gets watered. He has crews come to each site monthly to take readings and adjust settings based on the forecast.
It’s a Goldilocks approach to landscape watering: not too much, not too little, but just right.
Lawns and landscaping are polarizing symbols when we talk about water use in the desert. Some communities are paying homeowners to rip out their grass. Others, like this Chandler HOA, are trying to save water on the green fields that residents adore.
In nearby Gilbert, Arizona Jeff Lee is trying to nudge HOAs to look at watering that way.
Lee, a water conservation specialist for the town, traces an HOA’s landscape area using Google Earth Pro, converts that to square footage, then uploads the HOA’s monthly water usage to a vendor. The vendor, Waterfluence, analyzes the data using that month’s actual weather — not the historical weather conditions Dupper uses. HOAs and landscapers can see the results on a web portal.
“We can actually show them the cost comparisons,” Lee said. “How many dollars they should’ve spent on water and how many dollars they actually did spend on water based on what the landscaper was doing.”
Lee doesn’t want HOAs to underwater their large fields, trees and shrubs. The point is to let them know if they’re hitting that Goldilocks volume of water that maintains lush grass with low levels of water waste.
The Gilbert program is free for HOAs and voluntary. Lee said about 30 percent of the town’s 205 HOAs are enrolled. He estimated Gilbert saves over 200 million gallons of water a year through the program.
If you’re using too much water, though, getting on track can be expensive.
Kayte Comes is a board member of her HOA in Peoria, northwest of Phoenix. When her community, the Village at Vistancia, chose a new landscaper, they hired a firm that prioritizes conservation. Upon that firm’s recommendation, the board decided to replace parts of their irrigation system.
“Not every HOA, unfortunately, has the funds to do that,” she said. “But it’s gonna save your HOA in the long run.”
She added that a lot of businesses are willing to work with customers to help them afford upfront costs.
Some HOAs and landscapers are turning to so-called “smart controllers,” devices that adjust watering levels automatically. But Lee, Dupper and others say the smart controller is only as smart as the landscaper who programs it. Landscapers in Arizona can get a license if they pass two exams and have four years of experience.
“Part of the problem with the industry is it’s not advancing as fast as it should in the technical aspect,” Dupper said. “Because there’s no accountability or requirement to have it.”
The state of Arizona puts a water limit on HOAs in so-called “active management areas” in the middle of the state. Even then, it only applies to those with ten acres of landscaping or more. But with an increasing awareness of tech tools and water scarcity, more HOAs may be looking for that Goldilocks volume.
