In our drain field the excavator used an infiltration system. The trench is still dug but they insert what looks like a fifty-five gallon drum cut in half long ways.
The infiltration sections are about three to four feet long and hook together in the trench. Both the entry end and the termination end have a capped off section. The pipe coming out of the distribution box is connected to the entry end and then the fluid then infiltrates through the length and distributes out into the soil.
No gravel need in the trench means it saves time to install and the overall cost is cheaper.
