Central San Pleasant Hill Sewer Replacement Project


Central Contra Costa Sanitary District (Central San) will begin work in August on a major sewer replacement project within the Gregory Gardens neighborhood. Original sewers are being replaced, as they are near the end of their useful life. This work will benefit from two earlier projects where deeper large-diameter interceptor sewers were installed, allowing replacement with an increased slope for improved functionality. Open-cut construction methods will be used on streets, while work in easements will be completed using a horizontal directional drilling method (HDD), reducing construction impacts to properties during the project.

The work hours for the project are 8:00 a.m. to 5:30 p.m., Monday – Friday. Easement work will conclude at 4:30 p.m. During construction hours, Central San contractors will aim to minimize traffic delays and provide accessibility to resident driveways. Outside of work hours, all excavations will be filled or plated.
