Central Contra Costa Sanitary District - Grayson Creek Truck Line Project Main Page
Sewer Project General Background
Central Contra Costa Sanitary District - Grayson Creek Truck Line Project - This is a Central Contra Costa Sanitary District (CCCSD) major rehabilitation project and not a City funded project that will take place over the next 12 months.

The City is coordinating permit work activities with CCCSD which is expected to begin construction of the Grayson Creek Trunk Line Project on Wednesday, June 8, 2016. Mountain Cascade, Inc. (CCCSD hired contractor) will begin the installation of a new sewer main at the Contra Costa Canal on Westover Drive, between Westover Lane and Maureen Lane.

The work will be performed via the tunneling method and is expected to be completed in late June 2016. Construction activities will include traffic control, excavation, shoring, installation of the new pipe, and backfill. In order to complete this work, the southern lane/shoulder along Westover Drive at the trail will be closed during this phase of work. Traffic delays are anticipated during peak commute hours.

Traffic Alert

  • Westover Drive will continue to have one lane of traffic in each direction, and construction hours on Westover Drive will be from 8:30 a.m. to 6:00 pm. Informational signs as well as changeable message boards are installed strategically around the work area.

Motorists are encouraged to drive slowly through the work zones, and obey all detour signs.

For any questions, please contact the Chris Carpenter, CCCSD at (925) 229-7200.  For project information visit www.centralsan.org/construction.
