State to Help Fund Water Line Replacement

Map of the water line on Mercer Island

The City of Mercer Island has secured $1.2 million in funding for a new water supply line in the State of Washington’s Capital Budget that was recently adopted during the 2025 legislative session. The pipeline’s replacement became necessary after a leak in a segment was discovered in April of 2024, which required emergency repairs that reduced its overall capacity.

Given the importance of this water supply line, the City explored options for a stronger, earthquake resistant replacement that will improve overall resiliency of the water system. The City Council authorized staff to include design and construction of a new water supply line in the 2025-2030 Capital Improvement Plan (AB 6530). 

At its meeting on July 15, the Council formally expressed its appreciation for the efforts of the 41st Legislative District’s elected officials – Senator Lisa Wellman and Representatives Janice Zahn and My-Linh Thai – who applied for this funding on behalf of the City and voted for its inclusion in the Capital Budget.
