Planning and Engineering

NEW: Supreme Court Rules on Municipal Water Law - On October 28, 2010, the Washington State Supreme Court affirmed the constitutionality of the Municipal Water Law (MWL). The Court upheld the sections of the law that were invalidated on June 11, 2008 by the King County Superior Court.

These sections were the definitions of municipal water supplier and municipal water supply purposes, and the “in good standing” status of water rights based on system capacity rather than water use. The Supreme Court found that these sections do not violate separation of powers or facially violate the right to due process.

The decision means that municipal water suppliers are all Group A community water systems with 15 or more residential connections and Group A non-community systems that provide water for residential uses (such as bathing, cooking, and cleaning) to a non-residential population for 25 or more people for 60 or more days a year.

Water systems that meet the municipal water supplier definition will now have more water right flexibility and certainty, but they also need to include more information in their water system plan or small water system management program. 

The guidance documents and fact sheets below will help municipal water suppliers understand the benefits of MWL and comply with the additional requirements for their planning documents.  

NEW: Impact to privately owned water systems with a plan under review

If you are a privately owned system with a planning document currently under review, contact your ODW regional planner to discuss what additional information you need to submit before we can approve your document.

At a minimum, here is what must be included:

  • Documentation that your plan is consistent with local government plans (WAC 246-290-108).  This is required for water system plans only, unless you request to expand your water right place of use through your small water system management program.  See Local Government Consistency Review Checklist (PDF 35 KB)

  • Identified retail service area (WAC 246-290-100(4)(a)(iv)).  This is required for water system plans only.  The retail service area is where municipal water suppliers have a duty to serve.  See Municipal Water Law - Duty to Provide Service Requirement (PDF 120 KB)

  • Completed Water Use Efficiency Program (WAC 246-290-810).  This is required for water system plans and small water system management programs.  Additional information will be available in the Third Edition of the WUE Guidebook (DOH 331-375) coming in January.

NEW: Impact to privately owned systems with a plan approved between June 11, 2008 and October 28, 2010

If you are a privately owned system that received ODW approval of your water system plan or small water system management program between June 11, 2008 and October 28, 2010, your approval may have been impacted by the lower court’s 2008 ruling.  If you want to request an amended approval, contact your ODW regional planner to discuss what additional information you must submit in order for us to re-approve your planning document.

At a minimum, here is what must be included:

  • Documentation that your plan is consistent with local government plans (WAC 246-290-108).  This is required for water system plans only, unless you request to expand your water right place of use through your small water system management program.  See Local Government Consistency Review Checklist (PDF 35 KB)

  • Identified retail service area (WAC 246-290-100(4)(a)(iv)).  This is required for water system plans only.  The retail service area is where municipal water suppliers have a duty to serve.  See Municipal Water Law - Duty to Provide Service Requirement  (PDF 120 KB)

  • Completed Water Use Efficiency Program (WAC 246-290-810).  This is required for water system plans and small water system management programs.  Additional information will be available in the Third Edition of the WUE Guidebook (DOH 331-375) coming in January.

  • Additional information may be required depending on the situation. Contact your ODW regional planner to discuss before submitting additional material.

Note:  We will charge a review fee for all requests to amend a previous approval.
