Utilities submit water system and wastewater comprehensive plans to the King County UTRC. The UTRC reviews these plans for consistency with the King County Code (KCC) and Comprehensive Plan, and makes a recommendation on plan consistency to the King County Council.

Water Plan Process

King County’s authority for water system plan review is based on KCC 13.24 for those utilities that desire to obtain and/or distribute water in unincorporated King County and/or Title 57 Revised Code of Washington (RCW) for special purpose districts.

The King County UTRC Water System Plan Review Guidance Document (see link below) assists utility service providers and the UTRC in verifying that the plan is consistent with the KCC. The issues in the Guidance Document are the focus of King County's plan review.

The process for approval of a water system plan includes three phases:

  1. The UTRC works with the utility,
  2. Executive transmittal of an ordinance recommending approval of a plan, and
  3. King County Council ordinance review and approval.

In partnership with utilities, the UTRC strives to do timely and predictable reviews and make recommendations on plans. To that end, King County will attend Washington State Department of Health pre-planning meetings to ensure the County’s interests in water plan review are conveyed to the public water system utility early in plan development, and also to gain a current understanding of issues facing the public water system.

KCC 13.24 and the King County Comprehensive Plan provide the criteria for plan approval. The King County UTRC Guidance Document outlines the code or comprehensive plan subject and/or issues that members of the UTRC look for in a water system plan. Once the plan is received, it is reviewed by the UTRC. Within 90 days of plan receipt, a letter will be sent to the utility outlining the UTRC's comments and/or questions regarding the plan.

After the utility has had an opportunity to consider and respond to the UTRC comment letter, the utility representative will be invited to the next UTRC meeting where the plan will be discussed and recommended for approval by the King County Council. After the UTRC recommends the Council approve the plan, the UTRC prepares a legislation package containing an ordinance for the King County Council to consider. Once the Council approves the ordinance, and the Executive has signed it, a copy of the final ordinance will be sent to the utility.

Wastewater Plan Process

King County's authority for wastewater or sewer system plan review is based on KCC 13.24, KCC 28.84.050.E, and/or Title 57 RCW for special purpose districts. Wastewater system plans are approved by King County if the utility:

  • provides wastewater collection or treatment in unincorporated areas of King County;
  • is a component agency of the regional wastewater system; or
  • is a district organized under Title 57 RCW

The Guidance Document for King County's review of Wastewater System Plans (see link below) assists utility service providers and the UTRC in verifying that the plan is consistent with the KCC. The issues in the Guidance Document are the focus of King County's plan review.

Working with the utility and the draft plan, the utilities Technical Review Committee (UTRC) reviews the plan to assure that wastewater management in King County meet the requirements of the King County Code (KCC), other applicable statutory requirements, and is consistent with the King County Comprehensive Plan. The Director of the King County Department of natural Resources and Parks (DNRP) approves plans for component agencies that do not provide service in unincorporated King County. All other plans are approved by a King County Council ordinance.

Once the plan has been received, it is reviewed by the UTRC. Within 90 days of plan receipt, a letter will be sent to the utility outlining the UTRC's comments and/or questions regarding the plan.

After the utility has had an opportunity to consider and respond to the UTRC comment letter, the utility representatives will be invited to the next UTRC meeting where the plan will be discussed and be recommended for approval. For the Council approval of the plan, the UTRC prepares and the Executive transmits an ordinance package for the King County Council to consider. Once the Council approves the legislation, and the Executive has signed it, a copy of the final ordinance will be sent to the utility. For DNRP Director approval, the Utility will be sent a letter approving the plan.
