This is a construction drawing set for a public restroom facility project at Middle Fork Bottoms in Madison County, Tennessee, managed by the West Tennessee River Basin Authority. The project involves constructing a CXT Montrose restroom building (21'x28') with 2 sinks, 3 toilets, and 1 urinal, along with associated septic system infrastructure. The design includes a 6' wide ADA-accessible sidewalk connecting to parking and walking trails, a 1,000-gallon septic tank, 1,000-gallon pump tank, and field lines consisting of five 85' trenches with 4" HDPE perforated pipe.

The technical specifications detail a 500 GPD flow system with 1,000 SF of absorption area using Vicksburg soil type (30 MPI). The pump system utilizes a Zoeller Model 152 pump (4/10 HP, 115V) with 150' of 1.5" SCH 40 PVC force main. The septic field design includes specific requirements for gravel bedding (minimum 6" below pipe and 2" above) and maintains 6' of undisturbed material between trench locations. The drawings include detailed elevation specifications and construction requirements for proper installation of the septic system components.
