Norwesco ® Septic Tank Overview

The world’s leading manufacturer of polyethylene tanks, Norwesco® has been producing polyethylene septic tanks since 1980. With that kind of experience, Norwesco® offers you proven products that you can count on for years of dependable, trouble-free service. Norwesco® septic tanks are backed by a full three-year warranty from date of manufacture and have been approved by state and local health departments from coast to coast. Where applicable, Norwesco® septic tanks have been certified by both IAPMO™ and CSA™.

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:

Ease of Installation:

For septic system replacement and new home construction, all Norwesco® polyethylene septic tanks are designed for durability and quick, easy installation. Any Norwesco® septic tank can be transported to the job site in a pickup truck and carried by just two people. This enables you to install the tank on your schedule.

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 placement in our Legacy tanks 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. Our strict quality guidelines ensure an environmentally safe septic tank.

Single or Double Compartment:

We offer tanks in both single and double compartment (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.

Watertight Lid:

Norwesco® septic tanks come outfitted with a watertight lid. This improved design is significantly stronger than other lid designs. When leaving our factory, the lid will be attached to the tank with stainless steel screws and comes standard with a 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 (Get more info on accessories at https://www.norwesco.com/products/waste-water-tanks/below-ground-accessories).
