About this file
These are design-build concept plans for a Firing Range Building for the Clarendon County Sheriff's Office, located at 1 Wastewater Lane in Manning, South Carolina. The project involves constructing a 32'x52' building with a firing range, planned initially on April 7, 2025, and revised for rebidding on May 27, 2025. The facility will be a joint training facility situated adjacent to the Manning Wastewater Treatment Facility, with the building design including specific features such as double metal doors, an electrical panel, a future restroom, a service sink, and concrete pads at the front and rear entrances.
The project specifications detail technical requirements for the building and associated infrastructure, including a grinder sewage pump station designed to handle domestic wastewater. The pump system will utilize duplex submersible grinder pumps with 1-horsepower motors, operating at 230 volts and capable of maintaining a minimum flow rate of 30 gallons per minute. The wet well will be constructed from fiberglass-reinforced plastic, with a minimum sump diameter of 36 inches. The project also includes detailed erosion control plans, specifying construction sequencing, silt fence installation, and seeding requirements for the 0.4-acre disturbed area surrounding the construction site.

PART 1 - GENERAL
1.1 Provide all materials and installation for a complete and proper installation.
Coordinate work with City of Manning to avoid any existing utilities and make connection to manhole as required.
1.2 The grinder sewage pump station shall be designed to efficiently handle domestic wastewater and solids, utilizing duplex submersible grinder pumps with a 1-horsepower motor, operating at 230 volts, single-phase. This pump maintains a minimum flow rate of 30 gallons per minute (GPM), grinding solid waste into a fine slurry for easy transport through the force main. The semi-open impeller prevents clogging, while a stainless-steel cutting mechanism ensures reliable shredding of debris before entering the system.
1.3 The wet well shall be constructed from fiberglass-reinforced plastic (FRP), offering high corrosion resistance, structural durability, and a lightweight design for ease of installation. Fiberglass provides superior resistance to environmental degradation, making it well-suited for wastewater applications. The wet well typically includes a minimum sump diameter of 36 inches, allowing ample space for pump operation, maintenance, and solids retention.
1.4 For automated operation, the system is equipped with float switches or level sensors, ensuring seamless activation based on fluid levels. A 2-inch female pipe-thread (FPT) discharge port enables direct connection to the force main.
1.5 The 2-inch PVC force main, responsible for conveying wastewater from the pump station to the designated discharge point, is to be constructed from rigid PVC pipe, conforming to ASTM D2241 standards. The pipe shall have a minimum pressure rating of 160 PSI, ensuring durability under varying flow and pressure conditions.
Solvent-welded or gasketed joints provide flexibility, accommodating thermal expansion and contraction while maintaining a secure seal.
1.6 To facilitate identification and tracing, the PVC force main is green and clearly labeled “Sewer.” Additionally, trace wire and metallic detection tape are installed alongside the pipe, allowing maintenance personnel to accurately locate the force main when needed. Thrust restraints, such as concrete thrust blocks or restrained joints, are strategically positioned at bends and directional changes to prevent movement due to hydraulic pressure.
1.7 Pump system shall be manufactured by Franklin Electric, Liberty Pump or approved equal.
