    1250/350 Gallon Concrete Monolithic Septic Tank Overview

    Designed to hold 1600 gallons of liquid, this top-seam style concrete septic tank is a popular choice. Septic system plumbing designers and contractors appreciate this tank’s functionality. It provides home and property owners the ability to run pipes from the house to either of the tank’s side or center inlets.

    The same option is available on the outlet of the tank, extending to the leach field from the tank’s side outlet or from its middle outlet. Polylok IV closed end boots used on tank penetrations provide flexible, water tight connection to the pipe entering and leaving the precast structure.

    Our team of A.J. Foss experts manufacture precast concrete tanks that meet all best-practice requirements of ASTM C 1227 & NPCA.   Our service area includes customers in New Hampshire, Maine and northern Massachusetts.  Every job we support reflects the excellence that the A.J. Foss team is known for providing.
