Water

The City of Tualatin delivers water to nearly 60,000 people (27,000+ residents and 30,000+ employees) who live, work, and play in Tualatin every day! 

The City of Tualatin buys treated, ready to drink water from the City of Portland. Our water travels to us through about 50 miles of pipe, all the way from the Bull Run Watershed, a protected surface water supply in the Mount Hood National Forest. The Portland Water Bureau and the US Forest Service carefully manage the watershed to sustain and supply clean drinking water for nearly one million people (Tualatin included!). 

Our Work

Our Water Division is responsible for the operation and maintenance of the city’s water system. In other words, once the water gets to Tualatin, we inspect, maintain, and test our system so we make sure the water reliably gets to you.  Our water system includes:

What is a Water Master Plan?

Water is the most valuable resource we manage and we take that very seriously! Our Water Master Plan was last adopted in 2023 and ensures a long-term, reliable, and high quality water supply for Tualatin. 

A water master plan is 20-year planning document.  We use this plan to understand the current and future needs of the water system, which helps us to strategically invest resources and set rates. Going through the process of developing a “master plan” helps ensure that we’re investing wisely in the future of our water system. This plan considers: 

  1. Our Current Situation – Planning for the future requires that we understand the details of where we get our water, how much water we use right now, and a review of our existing infrastructure.
  2. Strategic Planning – This helps guide the City in its response to emergencies, water conservation efforts, and investments in our water system over time.
  3. Future Needs – Planning for the future includes lots of pieces, including population growth, impacts of climate change, and the age of our water infrastructure.
  4. Funding and Rates – Improvement and repairs cost money, so the plan also reviews water rates, costs, and fees.
