I called them to buy a septic tank and distribution box and they were very helpful and reasonably priced. I would buy from them again!!!!!!

I have had the opportunity to cross paths with AJ Foss many times over the past 10 years, and I have been consistently impressed with the quality of this organization. The number of contractors that trust AJ Foss for their precast concrete needs tells the story. Contractors don't want to insecurity, and the trust they put in AJ Foss speaks volumns. A quality family-run operation that has served southern NH for decades. If you are a contractor and you are NOT using AJ Foss, you owe it to yourself to check them out.

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.

About the Author:

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.
