This 200 gallon underground septic pump tank is built for residential and light commercial wastewater systems that require a dedicated pump chamber. Designed for below-grade installation, it gives contractors and property owners a reliable holding point between the septic system and the drain field, allowing a pump to distribute effluent at controlled intervals rather than relying on gravity flow alone. The single-compartment polyethylene construction resists corrosion and ground pressure, while the ANSI/NSF 61 approval confirms the tank meets recognized standards for contact with potable and wastewater liquids.

At 47'' W x 47'' D x 56'' H, this tank fits a compact burial footprint while delivering a full 200 gallon working capacity. The single 20'' gasketed manway provides the access needed for pump installation, inspection, and routine service without requiring excavation of the entire tank.

This pump tank is intended for underground installation as part of a septic system where effluent must be pumped to a leach field, mound system, or other secondary treatment area. Because it is not preplumbed, the installer connects the inlet, outlet, and pump fittings to match the specific system design. The black polyethylene body is UV-stable for above-grade staging during installation and resists the soil chemistry and moisture conditions typical of buried applications. Contractors specifying a pump chamber for a new build or a system upgrade will find the compact square footprint useful where burial space is limited.

Key Features:

• 200 Gallon Capacity: Provides a full 200 gallon single-compartment pump chamber, sized for residential and light commercial septic pump applications.
• Polyethylene Construction: Molded from polyethylene for corrosion resistance and durability in underground soil and moisture conditions.
• ANSI/NSF 61 Approved: Meets ANSI/NSF 61 standards for contact with wastewater liquids, supporting code-compliant installations.
• 20'' Gasketed Manway: The single gasketed manway lid provides a secure, sealed access point for pump installation, inspection, and maintenance.
• Underground Environment Rating: Engineered specifically for below-grade burial, making it suitable for standard septic system pump chamber applications.
• Not Preplumbed: Arrives without pre-installed fittings, giving installers the flexibility to configure inlet, outlet, and pump connections to match the system layout.

This 200 gallon polyethylene pump tank offers a compact, code-supportable solution for septic systems that require a dedicated pump chamber. Its underground-rated construction, gasketed manway access, and ANSI/NSF 61 approval make it a practical choice for contractors and property owners planning a new installation or replacing an existing pump tank.
