This 1,500 gallon underground septic tank is built for residential and light commercial wastewater management applications where a reliable, below-grade containment solution is needed. Designed to be installed underground, it keeps the system out of sight while providing a 1,500 gallon capacity that suits a wide range of household and site requirements. The two-compartment design supports the natural separation process that is central to effective septic treatment, and two 20'' gasketed manways give service technicians clear, accessible entry points for inspection and maintenance without disrupting the surrounding area.

The tank ships at 474 lbs. and is not preplumbed, so plumbing connections are completed on-site to match the specific layout of each installation. Liquid access includes one inlet and one outlet, each fitted with a 4'' gasketed PVC tee assembly, and the gasket-and-tee plumbing type provides a secure, leak-resistant connection method suited to underground use.

When planning a septic installation, this tank fits situations where a single-unit, two-compartment underground solution is preferred over multi-tank configurations. The 55'' W x 135'' D x 70'' H footprint should be confirmed against the excavation plan and local setback requirements before ordering. Because the tank is not preplumbed, the installer selects and connects the appropriate site plumbing during installation, giving flexibility to meet local code requirements. Confirm local permitting, soil conditions, and installation depth requirements with a licensed contractor before purchase.
