Enhancing the Environment with our Facilities

Unique Architecture

Unique architecture helps ensure our facilities are good neighbors that fit into the community and protect the quality of life for those who live or work nearby. Here are some examples of how design reflects community values and existing uses.

• Elliott West Combined Sewer Overflow Control Facility, Seattle
• Sweylocken Pump Station, Bellevue
• York Pump Station, Redmond

Elliott West Combined Sewer Overflow Control Facility, Seattle

The Elliott West CSO Control Facility at the Elliott Avenue and Mercer Street, which came online in summer 2005, helps manage heavy flows of combined wastewater and stormwater during rainy weather, protecting water quality in Puget Sound . King County involved community members in designing the facility to ensure it would fit into the neighborhood and preserve waterfront views.

Sweylocken Pump Station, Bellevue

The Sweyolocken Pump Station, located next to Bellevue Way and the Mercer Slough Nature Park (external link), sends wastewater from Bellevue and Mercer Island to King County's South Treatment Plant in Renton. A project to upgrade and modernize equipment in 2003 presented opportunities to improve design so the facility could fit into a small footprint and blend into the surrounding park.

York Pump Station, Redmond

The York Pump Station in Redmond was built in 1992 to send wastewater to South Treatment Plant in Renton. The pump station's red barn-like façade helps the facility fit into the rural character of the surrounding Sammamish Valley.
