This 1,250 gallon underground septic tank is built for residential and light commercial wastewater management where a reliable, code-recognized buried solution is needed. Designed for below-grade installation, it handles the separation and initial treatment of household sewage, keeping the process out of sight and out of the way. IAPMO certification means the tank meets recognized plumbing and sanitation standards, giving installers and inspectors a clear compliance reference.

The two-compartment design supports proper solids settling and effluent separation in a single unit, reducing the need for additional tanks in many standard installations. Two 20'' gasketed manways provide access for inspection and maintenance without requiring excavation of the entire tank, and the gasket-and-tee plumbing system at both the inlet and outlet simplifies connection to standard drain lines.

At 55'' W x 116'' D x 70'' H, this tank fits a range of residential lot configurations where underground placement is required by code or preferred for site aesthetics. The gasketed PVC tee assemblies on both the 4'' inlet and 4'' outlet allow straightforward field connection to existing or new drain lines. Because the tank is not preplumbed from the factory, installers have flexibility to configure connections to match site-specific pipe runs and depths. The 379 lb. shipping weight reflects a substantial but manageable unit for standard septic installation crews working with appropriate equipment.

Key Features:

• 1,250 Gallon Capacity: Sized for typical residential wastewater loads, providing adequate holding volume for standard household septic system requirements.
• IAPMO Certified: Meets recognized plumbing and sanitation standards, supporting code compliance for permitted septic installations.
• 2-Compartment Design: Promotes proper solids settling and effluent separation within a single tank, a key function of effective septic treatment.

This 1,250 gallon two-compartment septic tank is a practical choice for underground wastewater management where IAPMO certification, accessible maintenance points, and straightforward field plumbing connections are priorities. Review local code requirements and site conditions with a licensed installer before purchase to confirm this tank meets the specific depth, capacity, and configuration needs of the installation.
