We Need Your Feedback!

Willamette Water Supply Program staff are hosting three more open houses in late November and you are invited!  The open houses are an opportunity to learn more about the program, provide feedback on the potential pipeline routes and ask questions.  A virtual open house is also available online at through November 28.  
Recent open houses in Wilsonville, Beaverton and Aloha attracted community members, elected officials and others who provided valuable insight on potential routes.

Here’s the list of upcoming open houses:
Sherwood/ Tigard/ Tualatin
Saturday, Nov. 15

Wondering How the Potential Water Pipeline Routes Were Selected? 

The process to identify the preferred pipeline alignments began last year. When we started, we knew three things for certain: (1) the source of the water starts in Wilsonville; (2) water will be pumped from the water treatment plant in Wilsonville up to Cooper Mountain, where water storage tanks will be located (the mountain provides the ideal height for water delivery); and (3) from the tanks, water will flow by gravity using two pipelines that will connect to the existing system—one to the east and one to the west.
With that in mind, maps were studied, roads where driven and conversation with the various city and county staff began. After months of identifying possible routes, ruling out obviously bad ones and identifying where partnerships could occur with road improvements in Washington County and cities, the technical analysis began. 

Three important evaluation factors were then considered:
  1. Is the route acceptable / constructible?
  2. Will the route / pipe be resilient?
  3. How can we manage costs for ratepayers? 
More than 30 criteria in the following 8 categories were used to rank the routes:
  1. Social/Community Impacts
  2. Opportunities/Benefits
  3. Environmental Impacts/Permitting
  4. System Compatibility
  5. System Resiliency
  6. Constructibility
  7. Operation and Maintenance (O&M)
  8. Cost 
The public, at a series of open houses, is now reviewing the routes. Click here to learn more.  A preferred route will be selected in January 2015.  More outreach to pipeline route neighbors is planned in 2015. 
If you are unable to join us at one of the open houses listed above, please visit the online open house at OurReliableWater by November 28, 2014.
