2000 Gallon Concrete Septic Tank Overview

Our 2000 gallon septic tank is a mid-seam style precast concrete tank designed to hold 2000 liquid gallons. Plumbers can install it by running pipes from the home drains to either of the tank’s side or middle inlets.

Pipes can also extend from areas such as the side outlet or center outlet of the tank to the leach field.

Plumber tools such as Polylok IV closed end plumbing boots are used to create tank penetrations.  This achieves water tightness with flexible connection to pipes as they enter or exit the precast structure.

The A.J. Foss team manufactures and services waste water septic system tanks for home or commercial use that meet all best practice requirements of ASTM C 1227 & NPCA.
