About this file

This document contains engineering design drawings and details for a septic system upgrade project at the Buffalo Gap Campground located in the Dakota Prairie Grasslands. The key details include:

The project involves installing a new 2,000-gallon, H20 traffic-rated septic tank, replacing existing asphalt, and tying into the existing sewer line and lift station. The new tank will include access risers, a slide-in baffle wall, and an effluent filter. Detailed design drawings provide the tank dimensions, pipe connections, and asphalt repair specifications.

This project is associated with the federal contract opportunity 1240LU24Q0046 for the "GAOA Buffalo Gap Campground Septic System Dakota Prairie Grasslands", issued by the U.S. Department of Agriculture Forest Service. The contract opportunity provides the overall scope and requirements for the campground septic system upgrade.
