ARC Chambers

The Preferred Product in Leachfield Applications

The unique structural design of ARC Chambers makes it able to handle any conventional leachfield system challenge without sacrificing performance. The septic leaching chamber is a sturdy, lightweight polyethylene plastic unit that combines maximized infiltrative surface area and storage capacity. This combination allows for increased effluent dispersal performance and improved structural integrity.

  • Injection–molded from High Density Polyethylene (HDPE) for lightweight and sturdy design
  • 20–degree integral articulating joint that is ideal for either straight or contoured septic leachfield applications
  • True corrugated chamber design eliminates flat surfaces and provides increased load bearing capability in the trench
  • “Lock and Drop” joint provides a more positive connection during installation and backfill
  • A universal inlet/outlet end cap
  • Inspection vent ports on every unit with easy–to–remove knockouts for maximum job site flexibility
  • Convenient five–foot lengths are easy to handle
  • Diamond plate texture increases slip resistance and enhances ease of installation
  • Side Port Coupler snaps in place to allow side entry at any joint throughout the trench line
