Processing Before Disposal in a Landfill

Sludges, grease trap waste, grit trap waste, and other liquid wastes from municipal sources generally must be processed before disposal.

Disposing of Processed Liquid Waste in a Landfill

Waste solids produced by a municipal liquid waste processing facility can be accepted for disposal at a Type I municipal solid waste landfill if the material has been tested and certified to contain no free liquids.

Alternatives to Disposal in a Landfill

Some municipal liquid wastes may be composted, recycled, or applied to the land for beneficial use.
