    1250/500 Gallon Precast Concrete Septic Tank Overview

    This two-compartment area, mid-seam style concrete septic tank is designed for 1750 gallons of liquid. It offers plumbers the ability to run pipes from home drains to either the side or center inlet of the tank.

    The outlet area of this style of septic tank has the same available option. A plumber can run pipes out to a leach field from the tank’s side or middle outlet.

    Polylok IV closed end plumbing boots are used for the tank’s penetrations. This provides a flexible, water tight connection to pipes as they enter and exit the precast structure.

    This tank is appropriate for home septic tank installation jobs designed to support up to 6 bedrooms.  Plumbers, septic designers, and home owners can rest assured that our A.J. Foss team manufactures all precast tanks to meet the best-practice requirements of ASTM C 1227 & NPCA.


    • 1750 Gallon tank can service up to 4 bedroom systems where a larger pump chamber is needed to send waste water effluent to the leach field
    • Can also be used for up to 6 bedroom systems
    • Having two compartment areas helps separate the solids before the effluent leaves the tank
    • Is delivered pre-assembled for ease of installation service
