Draft Water System Plan

Review and Comment on the City of Chehalis Draft Water System Plan

The City of Chehalis Water System Plan (WSP) uses previous data between the years of 2017 and 2020 to analyze the City’s water system and document the current level of compliance with State policies and requirements in regard to items such as: source water protection; water quality; water system capacity; and water use efficiency. The WSP then projects estimated water use over a 20-year period (through 2040), identifies projected water system deficiencies and identifies Capital Improvement Projects (CIPs) to address the projected deficiencies over this 20-year period, and includes a financial program to fund CIPs over a 10-year period (through 2030).

The Draft WSP was submitted to the State of Washington Department of Health (DOH) on June 20, 2022. DOH issued comments on the Draft WSP on September 8, 2023, and the State of Washington Department of Ecology issued comments on the Draft WSP on September 21, 2023. A copy of the draft WSP is available at the following link:

Water Use Efficiency Goal Setting

DOH requires water systems to develop a Water Use Efficiency (WUE) Program which involves setting public water use goals for WUE. See Chapter 4 of the Draft WSP for a history on the development of the WUE Rule.

The City of Chehalis’ previous WUE goals were formally adopted in 2009. Chapter 4 of the Draft WSP documents current progress towards these previously developed WUE goals. Proposed revised WUE goals were developed as a part of this WSP and are shown in Chapter 4 of the Draft WSP. In developing these goals, public input was requested in a Public Hearing held on June 24, 2019, for which there was no public comment. Projected water use/demands with and without these proposed goals are shown in Chapter 2, Tables 2-7 and 2-8 of the Draft WSP.
