Central Broadway Water Main Upgrades

Beginning in mid-July 2023 or soon after, City contractors Tim Zanelli Excavating will upgrade the water main beneath Broadway between Temple St. and Boston Ave.

The water main in this area dates as far back as the late 19th/early 20th century. Old pipes suffer from tuberculation, a form of corrosion, which reduces the amount of water that the pipe can supply. 

Through this project, water mains in the neighborhood will be upgraded through a combination of replacement and rehabilitation (including processes such as cured-in-place pipe lining). Some water services (lines connecting individual properties to the water main) will also be replace through this project.
