The City of Los Altos sewer main repairs consist of lining the underground sanitary sewer pipes at locations noted below to mitigate corrosion. The project will also include sewer manhole rehabilitation at a couple of locations in the street on Bayshore Parkway.  The City of Los Altos awarded the construction contract to Insituform Technologies, LLC for this work.

The contractor will install “no parking” barricades as necessary in the area and will provide notices to the residents and/or businesses when work commences. This pipeline work and the manhole rehabilitation will not require digging.   All work will take place within the public right-of-way and no access to private property will be necessary.

The pipeline work cannot be accomplished when there is wastewater flowing in the pipe. Therefore, there will be an aboveground bypass piping system installed in the street or in the street shoulder area between each of the pipeline segments that will be lined.

The sanitary sewer pipes at the following locations will be repaired:

  1. San Antonio Frontage Road - 996 San Antonio Road to 998 San Antonio Road
  2. San Antonio Frontage Road/Easement - 998 San Antonio Road to 4007 Transport Street
  3. Easement at 4007 Transport Street/under State Highway 101 - 4007 Transport Street, under State Highway 101, to 2634 Bayshore Parkway
    The bypass piping for the sewer segments 1 through 3 (listed above) will be installed between the manhole on northbound San Antonio Road, located across from 870 San Antonio Road, north of E. Charleston Road, to the manhole at 1120 San Antonio Road, across from 1157 San Antonio Road and north of Bayshore Driveway.  The bypass piping will need to be in place until all three sewer segments have been lined and until the two manholes on Bayshore Parkway have been rehabilitated.
  4. El Monte Avenue – Intersection of El Monte Avenue and Hollingsworth Drive to the intersection of El Monte Avenue and Pilgrim Avenue
  5. El Monte Avenue - Intersection of El Monte Avenue and Pilgrim Avenue to intersection of El Monte Avenue and Marich Way
