Wastewater Services

Wastewater treatment facilities

To understand where WES stands today, it is helpful to know how far we’ve come regarding wastewater treatment services.

It’s hard to imagine not being able to flush a toilet to carry wastewater away from our homes or businesses and yet 60% of the world – 4.5 billion people – don’t have a toilet at home.

Boring Water Pollution Control Plant (serves Boring)

Location: 13305 SE Richey Road, Boring
Startup: 1986
Original Capacity: 150 population people

The Boring plant was built at the request of DEQ to eliminate raw sewage discharges to deep creek in the commercial area of boring. The plant serves 57 equivalent dwelling units. Today, our treatment facilities clean more than seven billion gallons of wastewater each year.

Hoodland Water Pollution Control Plant (Hoodland and Welches)

Kids by Digester

Original Capacity: 10,000 people

The Hoodland plant and collection system was built to replace four failing wastewater plants and allow the Hoodland area to grow.

Tri-City Water Pollution Control Plant (serves Gladstone, Oregon City and West Linn)

Digester
Location: 15941 S. Agnes Ave., Oregon City
Startup: May 1986
Original Capacity: 95,000 people

The Tri-City Plant was constructed as part of a major program to eliminate 15 raw sewage overflows to the Willamette and Clackamas Rivers and was built in response to a building moratorium. The Tri-City Plant replaced three obsolete plants in West Linn and Oregon City. The local share of the project was funded by a $25 million general obligation bond. The program also included major interceptors, and combined sewer separation projects in all three cities. The Tri-City plant was the first municipal plant in Oregon designed to treat ammonia biologically.

Today, our treatment facilities clean more than seven billion gallons of wastewater each year.

Kellogg Creek Water Resource Recovery Facility (serves the North Clackamas Urban area, and the cities of Happy Valley, Johnson City and Milwaukie)

Kellogg Plant
Location: 11525 SE McLoughlin Blvd., Milwaukie
Startup: August 1974
Original Capacity: 90,000 people

The plant was constructed to provide service to the North Clackamas Area which was being served by septic systems. Building in many areas of the district was suppressed until sewer service was available because the septic systems could not be permitted under then "new" state septic system regulations.
