Legacy Septic Tanks

Norwesco Legacy (ribbed) septic tanks are molded in one piece, requiring no additional assembly, reducing time and effort. These tanks cannot be used as pump tanks and must be kept full at all times. - The rib design and placement provide superior structural integrity to the tank. - Tanks 750 gallons and larger are available with PVC tees and gaskets supplied loose, or with installed PVC tees and septic adapters. - Lightweight - can be transported to the job site in a pickup truck and carried by just two people. - Available in both single and double compartment (2/3 - 1/3). - Accessories available to bring tank access to grade and to meet code specifications.
