SMART IRRIGATION
That was their main goal per their company-wide green initiative.”
– Andrew Moberly, Yellowstone Landscape “It’s really the only way to have your schedule adjust
daily without going to that site, doing your 10-step equa- tion and then adjusting for the evapotranspiration loss,” Moberly says. For him, there’s no better way to conserve water and save a client money than going to a weather- based controller right off the bat. He and his team provided the client with all of the dif-
ferent manufacturers they could think of to present multi- ple options. In the end, they chose a brand that Moberly had worked with in the past, as Moberly felt comfortable that it would fit his client’s needs best.
Controller installation
With the plan of installing weather-based timers set, Moberly, his team and the client looked at the project area’s portfolio to determine where the larger solid blocks of turf by square foot were, and thus where they’d start. “Whatever had the larger square footage of turf, we
would start there for a better return on investment,” Moberly says. “Tere’s tons of fescue turf out there that is watered during the growing season.” But when taking inventory of the existing system, the initial plan came to a slight roadblock. Initially, Moberly wanted to put master valves and flow sensors on every- thing. For about half a dozen of them, this plan didn’t work due to a 20-foot driveway in between the backflow and the timer. Te biggest issue was that he couldn’t get the wire path he wanted in some instances, so he had to get creative. Nonetheless, installation of the weather-based timers was able to commence. Employees from the controller manufacturer came out to the project area and provided training to Moberly’s staff, where technicians from his team learned how to use and program smart controllers. Together, the installation team became comfortable
with weather-based timers, learned how to program them and how to input the data they needed.

“They want to be on the forefront of this national market of water conservation.
The hard part
With the weather-based timers installed and data obtained, next came what Moberly described as the “hard part” of the project: finding out how to manage the system and get the most effective water conservation results possible. Tis is done, Moberly says, by carefully and individually auditing the entire system. “We’re going a little bit deeper into it and finding out
why exactly is this system using these gallons per minute, what is our precipitation rate, what is our distribution uni- formity, and then how can we better that?” Moberly says. “It’s a long process with a lot of math involved, but it’s an exciting one that’s just an ongoing process we’ve been deal- ing with.”
Moberly checks the pressure of a sprinkler as a coworker looks on. The auditing process, Moberly says, is what separates this irrigation project from others in the Nashville market.
