Your Reliable Drinking Water Future

A Clean And Reliable Drinking Water Supply Is Essential To Public Health And A Vibrant Economy

TVWD recently completed an important planning and decision process to determine the best mix of options for the District's future water supply portfolio. TVWD has enough water for today-but needs to take steps to have enough water to meet future demands. Projections show the population served will increase by 82,000 people by 2042.

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.

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. It will take more than a decade to plan, design and construct the new supply so the District must start now to make sure the required improvements are in place when needed.

How did you arrive at this decision?

TVWD identified and carefully evaluated a variety of water supply options. Options were shared with customers at a number of community briefings and customer input was considered. The Technical Memorandum is a summary of our current water supply evaluation efforts.

• Other documents and presentations

What are the next steps?

This decision provides the direction needed for the Board and staff to implement the mid-Willamette Option. TVWD's Board of Commissioners will hold a variety of meetings and work sessions to help guide staff with implementation. Visit the Board of Commissioners Meetings and Minutes Web site for more information.

Please check back soon for more information about the next steps. At this point in the process, we have received direction on pursuing the new water source and there will be future details on the various steps, tasks and outreach to complete this project.

What are the water sources?

Current Water Sources

TVWD's current water supply portfolio includes:

All of these supplies will continue to provide water for TVWD in the forseeable future. For more information about our current water supplies, visit our Water Supplies Web page.

Water Projects Underway

Aquifer Storage and Recovery - Miller Road

We are currently in the design phase of our new Miller Hill Road ASR. This will also be located in the Cooper Mountain area and will have the capacity to serve 2 million gallons per day for approximately 90-100 days. This facility is scheduled to begin construction in 2013 and be operational by the fall of 2014. This facility will have a residential appearance which will help it blend into the surrounding area. Check back for more project updates as this project begins construction.
