GUIDELINES FOR PREPARING & ADOPTING YOUR ORDINANCE OR STANDARDS
Interactive Online Book Version | PDF Version

Water and waste water purveyors from Idaho and Washington have teamed up to develop efficient irrigation and landscape design standards. A menu of options 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 to reduce runoff and keep pesticides, fertilizers, herbicides and automotive fluids out of storm drains, drywells, the aquifer and river.
