Project Spotlight: Water Providers Collaborate on Washington County Supply Line Projects

A blog repost from the Regional Water Providers Consortium's website 

West side supply lineThree water providers - Tualatin Valley Water District (TVWD), City of Tualatin, and the Portland Water Bureau - worked together on two projects on the Washington County Supply Line (WCSL) which delivers 60 million gallons of water from the Portland Water Bureau to west side wholesale customers.

First, TVWD and the City of Tualatin partnered together on an emergency pump station for the supply line. The trailer-mounted portable pumps can now be used to redirect up to 10-million gallons of water a day via the supply line from TVWD’s Wolf Creek service area to TVWD’s Metzger service area and the City of Tualatin in the unlikely event water supply from Portland is disrupted due to an emergency or natural disaster.

Second, the Portland Water Bureau took advantage of the construction window and upgraded the meter that measures the amount of water that they sell to a portion of TVWD’s service area.


By working together, the water providers were able to develop an important back-up water supply using existing infrastructure, improve resiliency, and achieve cost savings by coordinating construction projects.
