Water and wastewater purveyors from Idaho and Washington have teamed up to provide efficient irrigation and landscape design standards. This will help you implement best practices to conserve water during summer months when demand for outdoor water use can be three to four times higher than the amount used for domestic needs during the winter.
Water quality can also be protected by proper installation and maintenance of irrigation systems and backflow devices to reduce runoff and keep pesticides, fertilizers, herbicides, and automotive fluids out of storm drains, dry wells, the aquifer, and river.
These efficient irrigation and landscape design standards will help support growth, provide confidence to withstand drought conditions and protect the quality of our sole source aquifer. They provide voluntary actions that can have big impacts on conserving and protecting our precious water resources.
