Chambered Systems

The chambered system is a replacement for the conventional stone and pipe leaching bed. The chambers containing the distribution pipes are installed in 0.5 - 0.9 metre wide trenches. The pipes are not pressurized. Approximately the same length of trench is used as with the pipe system, only there is no crushed stone layer. 

Intended Use: 

  • Sites where access is a problem

  • Alternative to gravel-filled trench


  • Light-weight chambers can be hand-carried into position

  • No imported sand or gravel needed. Made of high-density polyethylene

  • Provides more infiltration surface area than a trench
