WHAT ARE THE DIFFERENCES BETWEEN A TRENCH SYSTEM AND A CHAMBER SYSTEM?
Trenches and chambers refer to the distribution lines section of a septic system. A trench system involves using 3″ or 4″ diameter, perforated, PVC pipe to distribute the liquid effluent to the soil for treatment. This option requires the use of clean, specifically-sized aggregate to specified depths above and below the pipe. A chamber system uses larger, half-pipe plastic sections linked end-to-end resulting in the system design length. No aggregate is needed in a chamber installation.
