Water Supply

Water Supply.


The plan to expand our water supply was approved in 2002.  The 2002 plan recommends three phases which are:


·         Phase 1 is the Stoney Mountain Transmission upgrade and springs exploration. 

·         Phase 2 is the Stoney Mountain Source Expansion, which is the construction of additional storage, transmission, and treatment facilities.

·         Phase 3 is the Willamina Creek Source Development which is the acquisition of additional water supply and treatment expansion.


Phase 1 was completed in 2000 at a cost of about $1.1 million.


Phase 2 is ongoing.  We built a 60 million gallon storage facility on Stoney Mountain using a 4 million dollar loan from OECDD for the project.  The next step in Phase 2 is the construction of a water treatment plant (estimated at a 2mgd capacity) along with transmission lines.  The estimated amount we can borrow for the entire phase is about $7.1 million.  Completion of Phase 2 would meet the estimated supply needs until 2030.  


Phase 3 is the acquisition of additional water supply from the Upper Willamina Creek.  In 2001 the City of Sheridan and the Confederated Tribes of the Grand Ronde Community of Oregon, with grant assistance from the Mid-Willamette Valley Council of Governments, commissioned a feasibility study for the development of the Upper Willamina Creek Reservoir study.  The final draft was presented in February 2004.
