These construction drawings are for the Middle Fork Bottoms Restrooms project by the West Tennessee River Basin Authority in Madison County, Tennessee. The project involves constructing public restroom facilities with specific infrastructure requirements, including a septic system designed for a public restroom with 2 sinks, 3 toilets, and 1 urinal. The facility is designed to handle 500 gallons per day (GPD) and will utilize a 1,000-gallon precast concrete septic tank and pump tank. The site plans include a 6-wide sidewalk for ADA accessibility, a Montrose restroom entrance facing the parking lot, and detailed specifications for field lines, pipe installations, and trench configurations.

The technical specifications outline precise engineering calculations for soil type (Vicksburg, 30 MPI), absorption area, trench length, and pump requirements. The project will use 1.5" SCH 40 PVC force main with specific friction loss calculations, and recommends a Zoeller Model 152 pump (4/10 HP, 115V, single phase). The construction drawings provide detailed elevation views, tank and pipe configurations, and precise grading and excavation instructions, ensuring comprehensive technical guidance for the restroom facility's infrastructure implementation.
