• Rotating Nozzles for Pop-up Spray Heads. Using mechanical spray heads can save up to 1,350 gallons of water per nozzle annually. Additional advantages include: reduced run-off, convenient pattern adjustment to reduce overspray, uniformity of water application and wind resistance.
	• Waterbrooms. Using a waterbroom instead of a nozzle to clean sidewalks and hardscapes can save up to 50,000 gallons of water per year. Studies have shown that a waterbroom requires up to 75 percent less labor to operate than a traditional garden hose with nozzle. An additional benefit is improved safety by using approximately 3 gallons per minute (gpm) versus 18 gpm on potentially slippery surfaces.
	• Cooling Tower Conductivity Controllers. Annual water savings with a new cooling tower conductivity controller can be as much as 800,000 gallons. Installing a state-of-the-art integrated pH Conductivity Controller will allow you to upgrade your cooling tower water treatment by adding chemicals that control the pH in the system. This may help prevent scaling in your cooling tower, even as you increase its water efficiency.
	• X-Ray Film Processor Recirculation System. The amount of water required to operate a non-digital x-ray film processor can be reduced by up to 98 percent. In one year, a typical film processing system needlessly sends hundreds of thousands of gallons of water down the drain. The average processor uses 788,400 gallons of water per year. With a recirculation system, you can reduce wash-water effluent to 13,530 gallons per year, which lowers water and sewage costs.
