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 for underground installation, it holds 1,500 gallons across two compartments, allowing for the natural separation of solids and effluent that is central to effective septic system performance. The tank includes a gasketed PVC tee assembly on both the inlet and outlet, along with two 20'' gasketed manways that provide access for inspection and maintenance without requiring excavation of the entire tank footprint.

At 55'' W x 135'' D x 70'' H and weighing 579 lbs., this tank is sized for standard residential septic installations. The gasket-and-tee plumbing type supports a secure, leak-resistant connection to your incoming and outgoing lines, and the dual manway design means both compartments remain accessible after installation.

This tank fits into a conventional septic system workflow where a primary treatment vessel is buried below grade and connected to a drain field or secondary treatment stage. The two-compartment layout supports the settling process by allowing heavier solids to remain in the first chamber while clarified effluent moves to the second before exiting through the outlet. Contractors and property owners planning a new septic installation or replacing an existing tank will find the pre-specified liquid access points and gasketed fittings useful for straightforward connection to standard 4'' PVC plumbing. Note that this tank is not preplumbed and does not carry IAPMO certification; confirm local code requirements before installation.

Key Features:

• 1,500-Gallon Capacity: Sized for residential and light commercial septic applications, providing substantial holding volume in a single underground vessel.
• 2-Compartment Design: Dual chambers support the natural separation of solids and effluent, a key function of effective septic treatment.
• Gasketed PVC Tee Inlet and Outlet: Both the 4'' inlet and 4'' outlet use gasketed PVC tee assemblies for a secure, leak-resistant connection to standard plumbing lines.
• Two 20'' Gasketed Manways: One manway per compartment allows for inspection and maintenance access after installation without full excavation.
• Underground Installation: Engineered for below-grade placement, keeping the system out of sight and protected from surface conditions.

This 1,500-gallon two-compartment underground septic tank is a practical choice for new septic system installations or direct replacements where a below-grade, gasketed-plumbing solution is required. Review all local permitting and installation requirements before purchase, as this tank is not preplumbed and does not include IAPMO certification.
