A grinder pump is placed in a tank (or well) that is buried in a convenient outdoor location on a homeownerâs property (grinder pump units also can be purchased for inside installation). The tank provides wastewater holding storage capacity. When water is used in the house, wastewater flows into the tank. When the wastewater in the tank reaches a pre-set level, the grinder pump automatically turns on, grinds the waste, and pumps it out of the tank via the homeownerâs on-site sewer service line and into the public sewer system.

The US EPA finalized the Universal Waste Rule (UWR) in the May 11, 1995 Federal Register. Many states have since adopted it. Universal Waste (UW) is a general descriptive term used to describe wastes that are generated by a large, diverse population.Businesses as well as unregulated households generate UW.arge Quantity Handler of Universal Waste (LQHUW)- This handler manages any of the three types of UW. A LQHUW collects greater than or equal to 5,000 kg. of the total accumulation of UW at any one given time, not by each type. A LQHUW may receive UW from other handlers and foreign destinations.
