The EPA has had on their water sense website tools for outdoor water conservation for a long time. They have tips on Landscaping, Watering Wisely and Irrigation Professionals. They have tools like, the WaterSense Water Budget Tool, http://www.epa.gov/watersense/water_budget/index.html .
The news is they now have WaterSense Landscape Irrigation Controllers, http://www.epa.gov/watersense/products/controltech.html .
The EPA estimates Residential outdoor water use in the United States accounts for more than 7 billion gallons of water each day, mainly for landscape irrigation. Experts estimate that as much as 50% of this water is wasted due to overwatering caused by inefficiencies in irrigation methods and systems. Existing irrigation control technologies can significantly reduce overwatering by applying water only when plants need it.
To earn the WaterSense label, landscape irrigation controllers must be able to adequately meet the watering needs of a landscape without overwatering. As with all other WaterSense labeled products, WaterSense labeled controllers will be third party certified to ensure that they meet the WaterSense criteria for efficiency and performance.
So consider a WaterSense labeled Controller on your next project.
