installing a pressure distribution drainfield

This pressure drainfield is 120 ft. A 30 ft, 40 ft, and 50 ft lateral. It was a tight spot to get that much drainfield into due to the fact the property line was close and it has to be a minimum of 5 ft off the property line.          

This is the squirt test to check the pressure head. 

Finished Drainfield

The design called for shallow trenches in order to maintain vertical separation. So in order to get enough cover over the infiltrator chambers some extra soil had to be brought in.
