Common uses for our Liquid Storage Tanks include the storage of fertilizer solutions, agricultural chemicals, water, liquid feeds and plant foods. All of our tanks are rugged, corrosion resistant and lightweight with no seams, welds or joints to leak or rust.

Norwesco‘s polyethylene septic tanks are designed for durability and quick, easy installation. The septic tanks are manufactured by means of the rotational molding process, which produces a one-piece, seamless, watertight tank. 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 septic tanks come equipped with manhole covers and detailed installation procedures. The 750, 1000, 1250 and 1500 gallon sizes are available in both one and two compartment configurations.
