Tolt II Pipeline

In order to improve our ability to continue to meet the needs of an ever-growing eastside community, Seattle Public Utilities constructed a second, larger pipeline from the South Fork Tolt River  Watershed to the SPU supply distribution system.

This pipeline allows SPU to more dynamically manage the balance of supply provided by the Cedar and the Tolt Watersheds, improving our capacity to react to storms or droughts, and making maintenance or repair of system components more effective.

It is just a piece of the puzzle of water supply, and along with the Tolt Filtration Plant, increases our ability to meet the long-term water supply needs of the greater Seattle area with the resources of the South Fork Tolt River Municipal Watershed supply system.
