Please consider the following features when you are looking to purchase a septic tank and you’ll find that Norwesco tanks will exceed your expectations when it comes to performance and longevity.

Rotationally Molded, One-Piece Construction
Norwesco septic tanks are manufactured by means of the rotational molding process which produces a one-piece, seamless, watertight tank.

Superior Strength Design
The rib design and rib placement provide superior structural integrity to the tank.

Excellent Chemical Resistance
Polyethylene is unaffected by soil chemicals and by the chemicals and gases present in sewage, so Norwesco septic tanks will not rust or corrode and require no additional coatings as other tanks do. Norwesco’s strict quality guidelines ensure an environmentally safe septic tank.

Single or Double Compartment
Our 750, 1000, 1250 and 1500 gallon tanks are available as single compartment or double compartment tanks (2/3 - 1/3). Prior to installing any septic tank, you should check with your local health department for specific requirements that your county or state may enforce.

Pre-Plumbed / Ready for Installation
Norwesco septic tanks (750 gallons and larger) are shipped to you ready for installation. Our pre-plumbed tanks include tee assemblies installed at the inlet and outlet. Tees are sized/cut according to each state code so the tank that you receive will be ready for installation.

Watertight Lid
Norwesco septic tanks come outfitted with a domed lid. This improved design is significantly stronger than other lid designs. When leaving our factory the lid is attached to the tank with four stainless steel screws and comes standard with a foamed, polyethylene gasket between the lid and the tank. The gasket provides a watertight seal at the lid area.

Accessories Available
Manhole extensions and lid-riser combinations are available to bring tank access to grade and to meet code specifications.
