Landscape Irrigation Sprinklers
Outdoor water use accounts for about 30 percent of average household water use nationwide. Current estimates are that residential outdoor water use accounts for nearly 9 billion gallons of water each day, mainly for landscape irrigation. This number rises dramatically in hotter and drier parts of the country.
To help increase outdoor water efficiency, EPA issued a Notice of Intent (NOI) (11 pg, 321K, About PDF) to develop a specification for landscape irrigation sprinklers in July 2014. Water-efficient irrigation sprinklers deliver water more evenly to the landscape than traditional sprinklers and also regulate pressure to help ensure a constant flow rate. Developing a specification that allows sprinklers to earn the WaterSense label will help provide consumers and irrigation professionals with additional water-efficient irrigation equipment options. The NOI outlined the performance criteria WaterSense proposed for both high-efficency nozzles and pressure-regulating sprinkler bodies, and identified issues that still need to be resolved.
Between July and September 2014, WaterSense solicited public comment on the NOI and specification development:
WaterSense analyzed the public comments, conducted additional research, and determined a path forward for this product category. To brief stakeholders on these developments, WaterSense is issuing Landscape Irrigation Sprinklers: WaterSense Specification Update (9 pg, 0.5MB, About PDF).
As of November 2015, WaterSense is moving forward with developing a specification for pressure-regulating bodies but has put developing a specification for high-efficiency nozzles on hold.
