Can I use a macerator to dispose of food waste to a drain or sewer?

Food waste disposers (i.e. macerators) cannot be used to discharge food waste to a drain or sewer in a non-rural area where a separate food waste collection service is available.

Systems which dewater food waste at source and store the solid material for collection and treatment are an acceptable form of management, but only if the loss of solid matter to sewers is minimal. Systems like enzymatic digesters which do not recover any organic waste prior to it going to sewer are banned under the Regulations as the food waste is all going into the sewer.
