Pipe Repair Complete, Water Supply Restored

Repairs and quality testing have been completed for the SPU water supply line and the line has been returned to service. This means Islanders can now resume normal water use.

Mercer Island’s water system received water from a smaller backup supply line for 120 days while emergency work was underway to repair a leak in the main pipe. During this time of reduced water supply, the community successfully curtailed water use to maintain adequate levels in the Island’s reservoirs. The City sincerely thanks our residents and businesses for their hard work throughout this emergency.

Water customers should not experience any change in water quality, safety, or pressure as part of the supply line transition. A small number of customers may experience cloudy water however this is temporary and water remains safe to use. Islanders with questions or concerns about their water service should contact the City’s Customer Service Team at 206-275-7600.
