LOCATION AND DESCRIPTION OF MAJOR COMPONENTS
Tank Assembly 9-1-0150-1 (Laundry SEP) and 9-1-0150-2 (General Purpose SEP)
NOTE
Not all production tank assemblies are fitted with manual drains.
The tank (1) has a holding capacity of 230-gallons. The inlet ports (2) are located on both sides and the
rear of the tank. The discharge port (3) and a drain port are located on the front of the tank, as is the
circuit breaker box. The discharge port is connected to the ejection pump installed in the tank via a check
valve that prevents back flow. A PVC ball valve (4) is installed onto the drain port and allows manual
drainage of the tank. A lid (5) secured with bolts and wing nuts is normally installed during operation. The
tank assembly is normally mounted on a wooden pallet (6) to facilitate movement with a forklift.
Tank Assembly 9-1-0527 (Waste Water Evacuation SEP)
The tank (1) on the Waste Water Evacuation SEP (9-1-0527) has a holding capacity of 220-gallons. The
inlet ports (2) are located on either side of the tank: two 3-inch inlets to accommodate graywater from the
Containerized Batch Laundry (CBL) and three 2-inch inlets to accommodate kitchen and shower
graywater discharge. The discharge port (3) is connected to the ejection pump and incorporates a check
valve to prevent sewage backflow into the tank. An access panel (7) on top of the tank is secured with
quick acting fasteners. The tank design of the Waste Water Evacuation SEP allows the unit to be
stacked two high, and incorporates an integral pallet to facilitate movement by forklift.
