Your Reliable Drinking Water Future
Moving Forward To Provide A Reliable Water Supply
Based on projected population growth and to help sustain Washington County's expanding economy, TVWD will require an additional source of supply around the year 2025. The District is moving forward on developing the mid-Willamette water supply option to provide quality water along with the Portland Water Bureau and Joint Water Commission.
Once the mid-Willamette supply is online, TVWD will receive water from three quality water sources.
Current Projects and Planning
This proposal is to design a water transmission pipeline that will be included as part of Washington County's 124th Avenue project. The pipeline design work includes a segment of the water transmission pipeline that will eventually become part of the Willamette River Water Supply System. TVWD estimates building this pipeline segment to coincide with highway construction will save $30 to $75 million.
For more information, look at TVWD's proposal to design a water transmission pipeline as part of Washington County's 124th Avenue project (PDF).
Work begins soon on a Willamette Supply System Preliminary Design:
- Preparing a preliminary design and establishing guidelines for the Willamette system to supply water to participating utilities
- Refining system hydraulics
- Establishing criteria for a new reservoir
- Identifying permitting requirements
- Preparing the overall schedule and cost estimates for required improvements

At the May 15 Board of Commissioners meeting, TVWD staff presented a resolution endorsing seismic upgrades to Scoggins Dam. Resolution 05-13 Endorsing Seismic Upgrades Of Scoggins Dam As Part Of A Regional Water Supply Strategy
TVWD has a variety of projects in motion to maintain and improve the water system now and in the future. Our Capital Improvement Projects Web page has more details about current projects.
How did you arrive at this decision?
TVWD identified and carefully evaluated a variety of water supply options. These options were shared with customers at a number of community briefings, and customer input was considered in decisions by the TVWD Board. A Technical Memorandum summarizes TVWD's water supply evaluation process.

On April 24, 2013, the District's Board of Commissioners voted to take steps to secure an additional water supply from the mid-Willamette River at Wilsonville. This option provides for high quality tap water at a lower cost, with less implementation risk than the other viable alternatives. This will be in addition to the other sources the District currently uses.
The Willamette River is a proven, abundant and reliable water source. The City of Wilsonville has been providing satisfied residents and businesses with water from the Willamette River for more than 11 years. Sherwood also draws on the Willamette as a source.
