General

General. Subsurface Drip Irrigation is a system that utilizes three basic design principles: (1) uniform distribution of effluent, (2) dosing and resting cycles, and (3) shallow placement of tubing. This system uses small diameter pipe with emitters and must be preceded by a treatment system that conforms to the manufacturer’s specifications particular to that system. The effluent must be adequately filtered before distribution to the disposal field(s). Only Subsurface Drip Irrigation Systems that provide for timed dosing are acceptable. The term manufacturer, unless otherwise specified, is considered the manufacturer of the treatment device. [See Figure 15.]
