These construction drawings detail the specifications for the Middle Fork Bottoms Restrooms project for the West Tennessee River Basin Authority in Madison County, Tennessee. The project involves constructing a public restroom facility with 2 sinks, 3 toilets, and 1 urinal, utilizing a septic system designed for 500 gallons per day. The site plans include a vicinity map, location map, and detailed technical specifications for the septic tank, pump tank, and field lines.

The technical calculations specify a Vicksburg (30 MPI) soil type with a required absorption area of 1,000 square feet of trench. The system will use a 1,000-gallon precast concrete septic tank and pump tank, with a 150' force main and specific piping requirements. The design includes a 6-wide sidewalk for ADA accessibility, a 21x20 restroom entrance, and field lines with specific installation instructions. The recommended pump is a Zoeller Model 152, 4/10 HP, 115V, single-phase unit, designed to handle the calculated total dynamic head and flow requirements of the facility.
