Los Alamos Sewer Project

The City of Santa Rosa is set to replace large portions of the existing Los Alamos trunk sewer to serve future demand.

Construction will begin at Streamside Drive and progress eastward to Elaine Drive

Project Background

This project will replace approximately 5,300 feet of the existing Los Alamos Trunk sewer pipeline that was installed in the 1950's. To improve performance, the new pipe will be 24 inches in diameter. It will be installed adjacent to the existing pipeline alignment, however, in certain locations it will be necessary to relocate small portions of the water main to create adequate separation from the proposed sewer line. Construction will begin at Streamside Drive and progress eastward to Elaine Dr.

 

Completing this project is crucial for the integrity of our community's infrastructure. Upgraded pipe materials will improve the performance of the sewer and water system. New sewer lines will reduce blockages caused by tree roots and minimize the need for repairs. They will also decrease groundwater infiltration into the sewer system, maintaining the effectiveness of our Wastewater Treatment Plant. New water lines will improve water flows and pressure to fire hydrants, protecting your home and property. Once the sewer and water improvements are installed, the streets will be re-paved, and pedestrian ramps will be improved where necessary.
