What is a drip irrigation system and what are its advantages?
Drip irrigation systems use a method of adding septic tank effluent to the soil that’s different than conventional trench systems. Drip irrigation systems use 1-inch diameter, flexible plastic tubing with small effluent dispensers every two feet. Tubes are buried two feet apart and 10-12 inches deep. The advantage of this type of system is that wastewater is added to the root zone, the most biologically active soil zone. The disadvantage is that wastewater must undergo a fairly expensive and separate pretreatment process to remove larger solids before entering the drip irrigation system. <
