Municipal Water Law
In 2003, the Washington State Legislature passed what is known as the Municipal Water Law. The law requires municipal water suppliers to use water more efficiently in exchange for water right certainty and flexibility to meet future demands. In response to the Municipal Water Law, the Washington State Department of Health requires municipal water suppliers to develop and implement a Water Use Efficiency Program meeting the requirements of WAC 246-290-810.
