We offer standard and low profile below ground septic tanks in both single and two-compartment configurations, all produced from three different manufacturers, including Norwesco, Snyder and Den Hartog Industries. Plastic septic tanks are manufactured by means of the rotational molding process which produces a one-piece, seamless, watertight tank. All plastic septic tanks feature a rib design which provides superior structural integrity to the tank and are designed and manufactured to meet wastewater treatment system standards. All of our plastic septic tanks are made from Polyethylene which is unaffected by soil chemicals and by the chemicals and gases present in sewage. Plastic septic tanks will not rust or corrode and require no additional coatings as other tanks do. All of our three septic tank manufacturers follow strict quality guidelines to ensure an environmentally safe septic tank. Prior to installing any septic tank, you should check with your local health department for specific requirements that your county or state may enforce.
