The Panel System began primarily because of insufficient space for conventional systems. A Panel System should be considered when: a quality effluent may be needed, space is limited, usable soil is limited, or there are indications that at some future time space may be needed for other development. The T & J Panel offers a 50% reduction on total line lengths in the state of North Carolina. A Panel System can be installed in conjunction with any distribution method. The biggest difference between the Panel and Conventional systems is the aerial area needed and the quality of effluent being introduced into the ground.
