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

Details:

• 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
