About the Norwesco Fluid 41721

The Norwesco 41721 is a 1000 Gallon Two-Compartment Yellow Septic Tank designed for durability and quick, easy installation. Backed by a full three-year warranty from date of manufacture, this 2-compartment septic tank features a corrugated ribbed design for superior structural integrity. The Norwesco 41721 is manufactured by means of the rotational molding process. This process produces a one-piece watertight tank with no seams to have to seal or stress over, and because it is made from Heavy Duty Polyethylene (HDPE), it is unaffected by sewage on the inside or soil chemicals on the outside. The Norwesco 41721 is a 1000 Gallon Two-Compartment Yellow Septic Tank comes with a water tight lid that is stronger than other lid designs and also includes a gasket between the tank and the lid to provide a watertight seal there too. To meet specific code specifications, and/or to bring tank access to grade, manhole extensions and lid riser combinations are available.
