The ADS ARC 36 Septic Leaching Chamber (ADS 3613BD2) is designed to replace the cumbersome and manually intensive gravel and leach systems commonly found in most septic waste water installations. Each 63" (60" repeat length) corrugated section is 34.5" wide and is made of high-density polyethylene. The Arc 36 by ADS features an open bottom for leach capabilities, a solid top for quick and easy burying, and louvered sidewalls to minimize soil intrusion and add strength. These sections conveniently interlock using an integral modified post and dome joint that allows for both straight line installation and slightly radial applications as well. Universal inlet/outlet end caps are available for professional and long-lasting connections to both gravity-fed and pressure-dosed septic systems.
