This document contains construction drawings and specifications from the West Tennessee River Basin Authority for restroom facilities at Middle Fork Bottoms in Madison County, Tennessee. The drawings detail plans for public restroom facilities including 2 sinks, 3 toilets, and 1 urinal, with associated septic system infrastructure. The project includes installation of a CXT Montrose restroom building with ADA-accessible sidewalk access, a 1,000-gallon septic tank, 1,000-gallon pump tank, and field lines consisting of five 85-foot trenches with 4" perforated HDPE pipe.

The technical specifications call for a 500 GPD flow rate system utilizing Vicksburg soil type conditions, requiring 1,000 square feet of absorption area via 333.3 feet of 3-foot wide trenches. The pump system uses a Zoeller Model 152 4/10 HP pump operating at 20 GPM with 17 feet of total dynamic head. The field lines require specific gravel bedding and covering requirements, with 6 feet of undisturbed material between trench locations. The drawings include detailed tank and piping specifications as well as elevation requirements for proper system operation.
