WEST SEATTLE FLUSH, PHASE 2: Where SPU is going next

(Click map for full-size PDF version)

The second phase of Seattle Public Utilities‘ West Seattle water-main flushing is about to start; the map above shows where the water pipes already have been flushed, and where the utility is going to be flushing starting this Sunday night.

If you missed the run-up to phase 1, SPU reminds you that it “is performing this work to help maintain water quality and reduce the occurrence of discolored water that some West Seattle customers have been experiencing. Flushing won’t eliminate discolored water, but it will help decrease it.” The “sediment” that leads to discolored water, SPU explains, comes from a rust buildup. (We had first word of the flushing plan back in March; the work began in April.)

Phase 2, according to the SPU notice sent to residents in the work zone (see the entire notice here), will involve work Sundays through Thursdays, 10 pm-5 am, over the next four to six weeks. Signs will go up in advance at hydrants that will be opened as part of the flushing. (This WSB story shows how the process works and what’s done at the work zones.)

SPU also notes, “When crews are flushing nearby, customers will experience discolored water, which should clear quickly once crews are done flushing the water main. Running the cold water for a few minutes can also help clear the discoloration.” If you have discolored water that doesn’t clear quickly, or any other water-quality problem, SPU’s 24-hour emergency line is 206-386-1800.

P.S. Here’s a deeper dive into your water’s backstory.

    Thanks for the update.   That reminded me to also flush my water heater and I keep getting a quarter teaspoon of sand out every time I draw off a big bucket.

Sorry, comment time is over.
