On August 1, 2024, Mercer Island announced the completion of repairs and quality testing for the SPU water supply line, allowing residents to return to normal water usage. For 120 days, the community relied on a smaller backup supply line while emergency repairs were conducted due to a leak in the main pipe. The city's proactive measures, including encouraging reduced water consumption, helped maintain adequate levels in the reservoirs during this period. Officials expressed gratitude towards residents and businesses for their cooperation and understanding throughout the emergency. While most customers should not notice any changes in water quality, some may experience temporary cloudiness, which is expected to resolve quickly.

The City has reassured the community that the water remains safe for all uses. Residents with questions or concerns are encouraged to contact the City’s Customer Service Team at 206-275-7600 for assistance. This successful restoration of water services underscores the city's dedication to maintaining a reliable water supply for its residents.
