New information today about Thursday’s sewer-pipe leak beneath Beach Drive, north of Lowman Beach. As noted in a late-night update added to our original coverage, it’s a King County Wastewater Treatment Division pipe, and right now, a crew is on scene using a video camera to get a closer look at the problem. We’ve talked with KCWTD spokesperson Marie Fiore, who says the pipe carries West Seattle sewage to the West Point treatment plant across Elliott Bay. It runs parallel to another pipe, so they had to “hand dig” to get to it for investigative purposes, so the other pipe isn’t damaged in the process, Fiore explained; that one is now carrying what would have been routed through the leaky pipe. She says they’re 70-year-old concrete pipes. Once the camera crew – whose work has traffic down to one lane, with flaggers, in the area right now – is done, they’ll know the timing and scope of repair work. Meantime, the Lowman Beach shore – affected by the seawall construction work right now anyway – will stay closed at least through the weekend, as Fiore says water-testing results aren’t expected back until Monday. They’re also working on an estimate of how much sewage spilled before the leak was stopped last night.
