Primary and secondary effluent can be reused for irrigation by a drip system. When a proper lateral line with an emitter size of 0.75 mm is selected, the plugging can be maintained at about 25% in which only 1% in contiguous plugging with 4 or 5 emitters plugged together. The plugging problem can be alleviated by periodical flushing and a closer emitter spacing design.
