No, installing the plastic bruiser 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. 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) 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. Can hot water be stored in plastic septic tanks? Do not subject the tank to water temperature higher than 100 deg F. Polyethylene storage tanks have a maximum storage temperature of 120 deg F. Contents with a temperature in excess of 120 def F, even for a short period of time, can weaken the tank’s structural integrity and make it susceptible to deformation and failure. 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. 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. We and the local manufacturers appreciate the opportunity to provide local pick up and the cooperation required for the process to be efficient.

Sustainability Score

42%
While Tank-Depot offers products that support sustainable water management, their corporate sustainability practices lack transparency. Limited information is available about their supply chain ethics, manufacturing processes, and environmental impact mitigation efforts. The company shows minimal public commitment to renewable energy or carbon reduction initiatives. Their recycling programs and end-of-life product management policies need significant improvement.
