Norwesco Legacy (ribbed) septic tanks are molded in one piece, requiring no additional assembly, reducing installation time and effort. Other features include:

• 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).
• Acccessories available to bring tank access to grande and to meet code specifications. Please note:

These tanks cannot be used as pump tanks and must be kept full at all times.
Across the United States and Canada there are a number of health code requirements that our tanks must meet. These codes are regulated by the state, county or province where you are located. To aid you in determining which tank you need, please consult with your local health department.
