Information for Generators of Municipal Liquid Waste

Find out how to manage and dispose of liquid waste from municipal sources, including grit trap waste, grease trap waste, septic tank pumpings, domestic septage, chemical toilet waste, municipal wastewater treatment plant sludge, other types of domestic sewage treatment plant sludge, and water-supply treatment plant sludge.

If you generate liquid waste from a municipal source, the waste must be processed or disposed of at an authorized facility. The waste may be disposed of in a landfill if has been processed to eliminate free liquids, or it may be composted, recycled, or applied to land under certain conditions.
