Water Use Efficiency

Water Use Efficiency Rule

In September 2003, the Washington State Legislature passed the Municipal Water Supply – Efficiency Requirements Act, also known as the Municipal Water Law. The Municipal Water Law required the State to implement the Water Use Efficiency Rule. The intent of this new rule is to help reduce the demand that growing communities, agriculture and industry have placed on our State’s water resources, and to better manage these resources for fish and other wildlife. Municipal water suppliers are obligated under the Water Use Efficiency Rule to enhance the efficient use of water by the system and/or its consumers. Union Hill Water Association is considered a municipal water supplier under the Municipal Water Law.
