We sell the following types of Water & Waste Management tanks:

Norwesco Polyethylene Septic Tanks
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 and have been approved by state and local health departments from coast to coast. Where applicable, NORWESCO septic tanks have been approved 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, NORWESCO’s 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 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 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.
