Oct. 11, 2009 Crews respond quickly to wastewater overflow at temporary pump station in Bellevue
Sewer utility employees quickly stopped a wastewater overflow discovered Sunday morning at a temporary pump station in Bellevue.
The Wastewater Treatment Division is investigating why pumps didn’t automatically activate at the temporary King County facility. After receiving an alarm at the South Treatment Plant in Renton at 10:43 a.m., crews were able to switch the pumps on manually within an hour. It’s estimated that about 36,000 gallons of wastewater overflowed, some of it into Meydenbauer Slough which feeds into Lake Washington.
County staff took water quality samples and notified health and regulatory agencies about the overflow. Crews cleaned up debris and used a Vactor truck at the site and will clean up additional material with a Vactor truck on Monday. The King County Wastewater Treatment Division is deploying the temporary facility while its permanent Bellevue Pump Station facilities at Southeast Sixth Street and 102nd Avenue Southeast are upgraded. The upgrades are expected to be complete in the Fall of 2010. Information about the construction project is available at: http://www.kingcounty.gov/environment/wtd/Construction/East/Bellevue.aspx.
