About this file

Written by GovTribe AI · Jul 28, 2026

This is a set of repair plans and technical drawings for a wastewater system at the Red River Work Center, a U.S. Department of Agriculture Forest Service facility located in the Nez Perce National Forest in Idaho County, Idaho.

The project involves comprehensive repairs to the sanitary sewer collection system, with a primary focus on manhole sealing. The repair plans include detailed technical drawings for sanitary sewer line installations, sewer profiles, and manhole construction details. The drawings specify the installation of 4-inch HDPE (High-Density Polyethylene) pipe at a 2% slope for all services, with multiple sewer lines designated as Lines A through E. The project includes provisions for removing existing manholes and abandoned sanitary sewer lines, installing new services with specific elevations and depths documented in cross-sectional profiles, and sealing leaking joints at precast concrete manhole barrel sections to prevent high groundwater infiltration. Manhole details specify the use of precast monolithic eccentric cone sections with concrete collar details and manhole steps set at 4-foot maximum intervals. The plans also reference flexible epoxy coating applications (Division 9950) for joint priming and sealing. The project was designed by William Griffith of Morrison Maierle, Inc., and was recommended by Susan Graves, District Ranger for the Nez Perce National Forest. The document set includes 24 sheets total, with the reviewed pages showing detailed sanitary sewer key plans, line-specific sewer plans and profiles, and manhole detail specifications.
