The Tri-City Service District is planning for the future

Wastewater and sewage treatment for Gladstone, Oregon City, and West Linn

The easiest way to understand the term “capacity” in regards to wastewater is to think of a unit of measurement called Equivalent Dwelling Unit (EDU). One EDU is roughly the amount of waste produced by an average household per day.

The second largest treatment plant operated by Clackamas County Water Environment Services (WES) on behalf of the Tri-City Service District is the Tri-City Water Pollution Control Plant, located in Oregon City. The Tri-City Plant currently treats the wastewater produced by 38,000  homes and businesses each day. 
 
Currently, the Tri-City Plant is leasing capacity to Clackamas County Service District No.1 (CCSD #1).   CCSD #1 is financing and building capacity at the Tri-City plant as part of larger efforts mandated by the Oregon Department of Environmental Quality (DEQ), known as the RiverHealth Capacity Management Program (CMP). The intent of the CMP is to relieve the over-capacity Kellogg Creek Water Pollution Control Plant, located in Milwaukie and ultimately protect public health and the Willamette River.
 
The CCSD #1-funded RiverHealth CMP, when complete in 2010, will return the 5500 EDUs of leased capacity to the Tri-City Service District. This project will provide enough capacity for both Districts until 2015.
