The EZflow septic system from Infiltrator Water Technologies is an environmentally friendly replacement to traditional stone and pipe drainfields. The lightweight, easy-to-transport and quick-to-install engineered geosynthetic aggregate modular units improve drainfield performance by eliminating the fines and reducing compaction and embedment associated with stone, according to the maker. Preassembled units include a 3- or 4-inch perforated pipe surrounded by aggregate held in place with durable, high-strength netting. Engineered flow-channels increase void space, creating improved water flow and greater storage. They are available in a range of easy-to-contour bundle configurations and diameters including 5- and 10-foot lengths and diameters of 7, 8, 9, 10, 12, 13 or 14 inches with simple snap internal couplers. The system is suitable for shallow applications, septic system repairs, and constricted or sloping sites. Frequently specified for commercial, community or cluster systems, additional applications include use with aerobic treatment units and in serial distribution, at-grade and pressure distribution systems. 800-221-4436; www.infiltratorwater.com.
