This 300 gallon septic pump tank is built for underground installation and designed to handle the demands of residential and light commercial wastewater systems. Constructed from polyethylene using ANSI/NSF 61 approved resin, it provides a reliable holding chamber for pump-assisted septic applications where gravity drainage alone is not sufficient.

At 54'' W x 54'' D x 54'' H, the tank offers a compact footprint relative to its 300 gallon capacity, making it a practical fit for sites with limited excavation space. A single 20'' gasketed manway provides the access point needed for inspection, pump installation, and routine service, keeping maintenance straightforward once the tank is in place.

This pump tank is intended for underground burial and works within a septic system where a pump chamber is required to move effluent to a drain field or secondary treatment area. The tank arrives not preplumbed, giving installers the flexibility to configure inlet, outlet, and pump connections to match the specific system design. Its single-compartment construction keeps the layout simple, and the black polyethylene body is suited to below-grade conditions. Contractors and property owners planning a new septic system or replacing an existing pump chamber will find this tank sized and configured for that purpose.

Key Features:

• 300 Gallon Capacity: Provides sufficient holding volume for pump-assisted septic applications in residential and light commercial settings.
• ANSI/NSF 61 Approved Resin: Polyethylene construction uses resin that meets ANSI/NSF 61 standards, supporting use in wastewater system applications.
• Underground Installation: Engineered specifically for below-grade burial, keeping the system out of sight and protected from surface conditions.
• 20'' Gasketed Manway: A single gasketed manway lid provides a secure, accessible entry point for pump installation, inspection, and ongoing maintenance.
• Not Preplumbed: Arrives without preset plumbing connections, allowing installers to configure inlet, outlet, and pump fittings to suit the specific system layout.
• Single-Compartment Design: One undivided chamber simplifies pump chamber function and keeps the internal layout straightforward for installers.

This 300 gallon polyethylene pump tank is a purpose-built underground septic component for systems that require a dedicated pump chamber. Its ANSI/NSF 61 approved resin, gasketed manway access, and flexible non-preplumbed configuration make it a practical choice for new installations and replacement projects alike.
