1,000 Gallon Concrete Septic Tank Overview
Our 1000 gallon septic tank, made of quality precast concrete, is designed to hold 1000 gallons of liquid. A plumbing team can extend pipes from home drains to either the side or center inlets of this mid-seam style concrete septic tank.
Plumbers in the New England area appreciate that this same option is available on the tank outlet. Pipes can carry waste water effluent from the tank to the leach field from either of the tank’s well-placed side or center outlets.
Closed-end Polylok IV plumbing boots are used for the job of installing the tank’s penetrations. This provides flexible, water tight connection for pipes as they enter and exit the precast tank structure.
Our team produces and services this commonly-used style of tank to meet all best-practice requirements of ASTM C 1227 & NPCA. A.J. Foss serves home and business waste water service needs by partnering with area septic system designers, plumbers, and excavation professionals throughout New Hampshire, Maine, and Northern Massachusetts.
This smaller-sized tank is mostly used as a pump station, holding tank, or for adding capacity to an existing septic system. That’s because the NH Department of Environmental Services (DES) Subsurface Systems Bureau revised state rules in 2012. This obsoleted specification of this tank for jobs in NH involving home waste water tank system installation.

My father started the Andrew J. Foss, Inc. precast concrete company in 1963 at the age of 19. My precast education started at a very young age. He taught me everything I know about creating quality precast concrete products, from septic tanks to concrete headwalls. He also taught me to succeed in business you need to offer an exceptional product and treat your customers as you would expect to be treated. Now, as an owner of the company along with my brother Matthew, we've taken everything we've learned from our father to start the next generation of our family-owned precast concrete company.
