In April 2016, Seattle Public Utilities (SPU) began a comprehensive program to flush water mains throughout West Seattle neighborhoods.
SPU is performing this major water main flush 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.
SPU completed flushing water mains in the North Admiral area of West Seattle in the summer of 2016. Beginning October 9, crews will move south to continue flushing. They will work Sunday through Thursday at night starting around 10 p.m. and ending at 5 a.m.
Yes. Seattle’s water is tested daily and is safe to drink. If your water is temporarily discolored, wait until it clears before drinking it.
Residents and businesses don’t need to take any action to prepare for this work. Customers will be able to use their water as usual. When crews are working nearby, customers may notice a slight reduction in their water pressure. They may also see temporary discolored water, which should clear quickly once crews are done flushing the water main. Running cold water for a few minutes can also help clear the discoloration.
If you experience any problems with your water or cannot get it to run clear, contact SPU’s 24-hour emergency line at (206) 386-1800.
Flushing the water mains will remove some of the sediment and rust that has been resting in the pipes. This will help reduce the level of discoloration and the time it takes for the water to clear when there’s a disturbance in the pipes.
