Storm Drainage

The drainage plan says where the water goes. We put in the pipe and structures that get it there.

The Scope

RCP, HDPE, and CMP in whatever the drainage plan calls out. Catch basins, junction boxes, drop inlets, headwalls at the outfalls.

Culvert crossings, detention outlet structures, and the underdrains nobody thinks about until a parking lot starts pumping water up through the joints.

SHOT 16 Headwall poured at the outfall

What Acceptance Takes

  • Invert elevations shot against the drainage plan
