Why use pipe and gravel fields?
The pipe and gravel septic system is a time-tested and proven system. Pipe and gravel fields are gravel trenches with embedded perforated pipe. The pipe distributes the waste water over a specified area allowing for water discharge to evaporate and be effectively absorbed by the surrounding soil. Sometimes systems laid in clay or dense soil also require the assistance of a curtain drain around the septic area to divert groundwater from the septic area so as not to flood the system.
