City pushed as smart sprinkler test site

RALEIGH Mecklenburg lawmakers and leaders of North Carolina’s Green Industry Council are pushing for a half-million dollar pilot project that would help bring smart sprinklers to the county and potentially save thousands of gallons of water.
The key to lowering the water flow is for businesses with wide swaths of grass and landscaping to water their lawns based on satellites and high-tech weather gear, not a timer.
If successful in Charlotte, the Green Industry Council hopes to take the project statewide.
Time Warner Cable recently installed such a system at its offices on Crescent Executive Drive and anticipates saving buckets of water and money, $25,000 over three years.
Charlotte’s utility chiefs have asked state officials to fund the program with $500,000 of federal stimulus money, but Sen. Dan Clodfelter, a Charlotte Democrat, fears politics may be interfering.
Charlotte already received two water grants through stimulus money, and state officials may feel like they need to spread the money around more, he said.
“We need to gear up and talk to (stimulus czar) Dempsey Benton,” Clodfelter told fellow Mecklenburg lawmakers at a breakfast Tuesday, encouraging them to telephone Benton, who oversees the federal economic recovery money flowing into the state.
The water management program would identify Mecklenburg’s top 100 water users. Those customers would be invited to workshops on managing their outdoor sprinkler systems through new technology. Instead of arbitrarily turning on the sprinklers for 20 or 30 minutes at a set time, companies could install technology that uses satellite and ground-based measurements of factors such as temperature, humidity and wind.
“It can pinpoint the weather down to a one (square) kilometer area,” said Mark Peters, a leader of the Green Industry Council, who runs Piedmont Carolina Landscaping in Greensboro.
The grass might need only four minutes of watering one day instead of 20 because of clouds and low wind.
“How many times have you driven down the street and (automatic) sprinklers are on and it’s pouring down rain?” said Susie Glass, director of corporate facilities for Time Warner.
She said the water technology is one of several environmental conservation steps the company is taking.
Companies likely would pay around $4,000 to install the system on a 2- to 3-acre site but would quickly recoup that money in water bill savings, Peters said.
Charlotte officials can examine water bills and quickly identify the largest users, said Buddy Murrow, manager of Shepherd’s Supply nursery in Huntersville and a Green Industry Council leader who joined Peters in presenting details of the water management program at the Tuesday breakfast.
“The city could have this project rolling in 30 to 60 days,” Murrow said.
