Underground Fiberglass Septic Tanks                                  back to underground tanks

• Septic tanks are 100% water tight when installed to the manufacturers’ installation instructions.
• Septic tanks’ water tight connection is ensured by the fiberglassed inlet and outlet PVC fittings.

• Septic tanks offer flexible design options including configuration for:
• • Slide rails.
  • Pump quick-disconnect systems.
  • Pump platforms (used for submersible centrifugal pumps).
  • Riser openings with internal flanges (used to hang pump vaults for turbine pump applications); riser openings can be designed anywhere on the tank top.

• Septic tanks can withstand an H-20 traffic load.
