information from King County

Beginning mid-September, repairs will begin on the County’s Alki Regulator Gate. This is a below- ground structure located at Southwest Spokane Street, near the corner of Beach Drive Southwest (see map above). This facility is part of the County’s regional wastewater system; it helps regulate flows going to the West Seattle tunnel and pump station. The repairs are important to help avoid wastewater overflows into Puget Sound during times of high flows in the system.

Details of the work
• Repairs include removing broken concrete, clearing obstructions, and cleaning the flow gate frame and guides.
• Work will be below-ground with support equipment on the surface, including a generator for the ventilation system.
• There will be traffic control in place to direct vehicles around the work area.
• Day and night work is planned (during times of low sewer flows).
• The work is expected to take up to two weeks to complete.

Future work: Later this summer, the County will install a flow meter near the corner of Southwest Spokane Street and 62nd Avenue Southwest. Future work at the 63rd Avenue Pump Station (Beach Drive Southwest near Southwest Spokane Street), will take place in 2015.
