  • Frequently Asked Septic Tank Questions

    1. Can I install a septic tank under a driveway?
  • No, installing the plastic septic tank under a driveway is not permitted and will void the warranty. Do not locate tanks beneath driveways or in the pathway of heavy or vehicular traffic areas.

  • 2. Is there a sand/gravel mixture recommended for bedding/backfill?
  • Yes, the sand/gravel mixture, commonly called “pea gravel” mixture is recommended. (See Installation Instructions Above)

  • 3. Can I use a septic tank above ground?
  • Underground plastic septic tanks are designed for below ground use only. Using the tanks above ground can result in deformation of the tank. It is far more cost-effective to utilize an above ground storage tank that is specifically designed for above ground use and applications.

  • 4. Can hot water be stored in plastic septic tanks?
  • Do not subject the tank to water temperature higher than 100° F. Polyethylene storage tanks have a maximum storage temperature of 120° F. Contents with a temperature in excess of 120° F, even for a short period of time, can weaken the tank’s structural integrity and make it susceptible to deformation and failure.

  • 5. How do you access underground plastic septic tanks?
  • Each plastic septic tank comes equipped with manhole access hatches (1 or 2 depending on tank). In addition, risers can be added to the top of the tank providing ground level access. Without a riser you would need to dig up the soil above the manway to gain accessibility.

  • 6. Can I pick up a plastic septic tank nearby?
  • In many cases yes. To pick up a plastic septic tank and save on freight, requires you placing your order. Upon being notified that the tank is ready for pick-up, we will provide you with a 6 digit trip # which allows you go and pick up your tank M-F 8:30 am - 2:00 pm.
