Water Master Plan

The Joint Water Commission (JWC) partners – including the Cities of Hillsboro, Forest Grove, and Beaverton, and the Tualatin Valley Water District – are in the process of updating the JWC Water Master Plan, previously revised in 2009.

The plan will detail strategies for continuing to provide safe, reliable, and sustainable water to customers over the next 30 years, and includes the following components:

  • JWC Water Treatment Plant inventory and evaluation of existing system conditions
  • Water demand study
  • Analysis of the JWC Water Treatment Plant’s facilities
  • JWC Water Treatment Plant seismic assessment
  • List of recommended capital improvement projects

Water Master Plans are required by the state to address future needs of the water system, which must follow all state and federal drinking water standards. 


  • Winter 2021: Plan development
  • Spring 2023: A draft is available for public comment
  • Summer 2023: Finalized plan ready
