152nd Ave S Watermain Project

Project Overview

Construction of approximately 1,700 feet of 12-inch ductile iron watermain on S 152nd Street along with hydrants, valves, services, and other appurtenances. The work also includes replacement of one 12-inch check valve vault assembly, one 3-inch commercial meter assembly, connections to the existing water system, trench repair, new ADA ramp and sidewalk improvements, and full street paving.

 

Project Status

Finalizing Construction: The existing water main was an undersized, dead end 6” caste iron pipe from the 1960s that needed a lot of maintenance, including regular flushing. Using funds from the water enterprise fund, 2,000 feet of the water main was replaced with a 12” ductile iron water main and extended through Ladera and Sunwood to tie into the existing water main along Sunwood Blvd, thus improving water quality for residents and reducing maintenance for City staff. Various improvements also took place as part of the project, such as new signs, ADA ramps, repaired sidewalk panels, new meter boxes, and a full width overlay and striping of 152nd Street in its entirety. The current construction is expected to be completed and accepted by the City in Q2 of 2024.
