That sign was up this afternoon near the 63rd Avenue Pump Station south of Alki Point, following the 330,000-gallon combined-sewer overflow reported late last night by King County Wastewater Treatment. The overflow happened during Thursday afternoon’s less-than-one-hour power outage in western West Seattle, before a portable generator could be brought to and fired up at the pump station.
We followed up today with county spokesperson Doug Williams. For one, as commenter Schwaggy asked, why isn’t there already a generator at the pump station? He says there soon will be:
We are wrapping up a construction project at the 63rd Avenue Pump Station that, when finished, will include a new emergency power generator at the facility. While that construction project is underway, we have an emergency generator loaded on a trailer and stationed at the Alki CSO facility. Yesterday when our workers got the 63rd Ave pump station overflow alarm they went to the Alki facility and picked up the emergency generator for the short drive over to the pump station (about ¼ mile, I believe). However, power was restored before the emergency power was brought online.
As for how long the signs will stay up, Williams didn’t have information on water-quality-test results yet when we checked in, but he said the signs will not be taken down until results are “below thresholds for human contact.”
