The M6-EV from Consolidated Treatment Systems is designed to offer a complete treatment system in a single excavation. The system’s three-in-one tank provides a 310-gallon pretreatment tank with sanitary tees, a 500 gpd Nayadic aerobic treatment unit, an 830-gallon pump tank with a control panel for dose or sprinkler applications, a compressor with optional internal or external housing, a mounted junction box for electrical connections, an effluent filter, and a high-head discharge pump. It is 8 feet 5 inches long, 6 feet 4 inches wide, and 82 inches tall, and weighs 1,220 pounds, making it usable in tight lots. Fiberglass construction eliminates the need for cranes or boom trucks to set the unit. 800/503-0163; www.consolidatedtreatment.com.
