This 1,000-gallon underground septic tank is built for residential and light commercial wastewater management where a reliable, below-grade containment solution is needed. Sized at 52'' W x 101'' D x 71'' H, it provides substantial holding capacity in a single-compartment design that fits standard septic system layouts.

The tank ships not pre-plumbed, so installers connect site-specific piping to the included gasketed PVC tee assemblies at both the inlet and outlet. A 20'' gasketed manway provides access for inspection and service after installation. Proper backfill is required during installation: the source specifications call for 25% backfill to support the tank structure underground.

This tank is intended for underground installation only and uses a gasket-and-tee plumbing configuration, making it compatible with standard 4'' PVC septic system piping. The single-compartment layout suits straightforward septic applications where a two-compartment or multi-stage system is not required. Because the tank is not pre-plumbed, installers have flexibility to route inlet and outlet lines to match the site plan. Buyers should confirm local code requirements, setback rules, and any required permits before installation, as septic system regulations vary by jurisdiction.

Key Features:

• 1,000-Gallon Capacity: Provides substantial underground wastewater holding volume suited to residential and light commercial septic applications.
• Gasketed PVC Tee Plumbing: Both the 4'' inlet and 4'' outlet use gasketed PVC tee assemblies, supporting a secure, leak-resistant connection to standard septic piping without special fittings.
• 20'' Gasketed Manway: The single manway lid allows access for inspection, pumping, and routine maintenance after the tank is buried.
• Underground Installation Design: Engineered specifically for below-grade placement; 25% backfill is required during installation to properly support the tank.
• Not Pre-Plumbed: Inlet and outlet connections are not factory-installed, giving installers the flexibility to route piping to match the specific site layout.
• Single-Compartment Configuration: One-compartment design simplifies installation and suits standard single-stage septic system requirements.

This 1,000-gallon underground septic tank offers a practical, single-compartment solution for below-grade wastewater containment. With gasketed tee connections at both the inlet and outlet and a serviceable 20'' manway, it supports straightforward installation and long-term access. Confirm local permitting and installation requirements before ordering.
