Applications & Benefits


It is estimated that approximately 25 percent of the U.S. population lives without access to public sanitary sewer systems. Properly performing on-site septic systems provide a critical health and safety function in these American homes. On-site septic systems depend on properly designed soil absorption systems that allow for the flow of effluent and a leach field that can function with little maintenance. ADS provides a wide range of gravel-less products to offer the right solution for your on-site needs. For homeowners, contact your local Health Department or County Sanitarian for information on which products or sizes meet your state and local requirements.


Our on-site leach chambers and septic stacks offer bigger time savings, reduced footprints and reduced overall cost than conventional systems like crushed rock and forest pipe. Our products are easily transportable for installation and offer configuration options to fit your unique project. All of our high-density polyethylene septic products are inert and corrosion resistant to household effluents and are IAPMO certified. 

Our on-site leach chambers include  ARC™ Chambers and BioDiffuser® Chambers. ARC™ Chambers are the preferred product to accommodate both gravity-fed and pressure-dose systems with quick installation into trench or bed applications. It is injection-molded from High-Density Polyethylene (HDPE) for a lightweight and sturdy design. BioDiffuser® Chambers are uniquely designed for trenches varying in width and length. For easy installation, this product’s post and dome joint configuration require no screws. 

Septic Stack units allow for exceptional soil contact without the use of gravel. Our Septic Stack™ Pipe System is designed for both residential & commercial trench, mound, bed and other configurations. Available in configurations of 9, 11, and 13 pipes, this system functions as a trickle filter, dispersing effluent into the voids in and around the specially-banded ADS 4” (100 mm) pipe. This pipe is engineered with holes and slots, allowing it to collect and disperse the effluent as it passes over the pipe’s configurations.
