Grass Valley Sewer Mains and Manholes Repairs

Pipeline Replacement Design Addresses Steep Terrain, Creekside Alignment, and Private Property Crossings

Bennett Engineering Services was selected to prepare plans, specifications, engineering cost estimates, and schedules for the lining and repair of sewer main lines and manholes throughout the City of Grass Valley.

The evaluation included approximately 10,000 linear feet of 6-inch, 3,000 linear feet of 8-inch, and 3,000 linear feet of 10 to 24-inch sewer main. The plans for this gravity-fed system included trenchless repairs for areas of cracking and infiltration and open trench construction where required for pipeline sagging or severe joint offsets.

Project challenges included steep terrain, main lines and manholes along creeks, and large segments of the system running through private property.
