How Does it Work?

The 4 foot vaulted Infiltrator chambers replace traditional PVC pipe and crushed stone. The chambers are buried, locked end-to-end and capped with dome-shaped end plates to create a large half-tube structure. Effluent from a septic tank flows freely into the chambers and is filtered efficiently into the soil absorption area. In addition, septic outflow can be split with a distribution box so the chambers can run parallel to each other in order to minimize the footprint of the leach field. Please comply with your state and local septic regulations.

Additional Information

  • The Infiltrator is the original plastic leach field chamber developed over 25 years ago.
  • More than 1 Million systems installed with over 27 Million units in the ground in all 50 states and 13 countries.
  • It takes the place of old-fashioned rock and perforated pipe leach fields-no rock is required!
  • Simply dig your trench, place chambers into the ground, snap together end-to-end, and backfill with the original soil.
  • The Quick4 model allows a 10-degree left or right turn between chambers, providing flexibility to accommodate natural terrain features and to avoid obstacles.
  • Chambers are made from chemical-resistant polyethylene, so they won't deteriorate or corrode.
  • Manufactured from recycled materials. Infiltrator is one of the top ten recyclers in the U.S.
  • Powerful arch design supports wheel loads of 16,000 pounds per axle, equivalent to an AASHTO rating of H-10. H-20 units also available.
  • ISO 9002 Registered and I.A.P.M.O. and UPC-approved.
  • All Infiltrator products carry a limited warranty.

Infiltrator Systems VS Traditional Stone & Pipe Systems

A 12-foot length of Infiltrator chamber trench has a more effective infiltrative area than a 25-foot length of stone and pipe trench.


Infiltrator Systems
Traditional Stone & Pipe System
  • Easy assembly and installation by two people
  • Only a backhoe and pickup truck needed.
  • Lightweight chambers can be delivered in one pickup truck load and hand-carried into position.
  • Entire trench bottom is open for effluent infiltration with 100% efficiency.
  • There is less regrading, tree damage, and no stone cleanup.
  • Inspection port is available for easy access to leach field with no site disruption.
  • Solid-topped chambers need no geotextile.
  • Overall lower cost.
  • Labor-intensive, lengthy installation.
  • Dump truck needed for stone delivery.
  • Stone hauling adds expense and time and increases soil compaction.
  • Stone in trench reduces Long-Term Acceptance Rate by more than 50%
  • Heavy traffic across yard and spilled stone mean more site repair needed after installation.
  • System lacks easy inspection and monitoring of leach field without digging up the yard.
  • Geotextile required on top of stone.
  • Overall increased cost.
