Model Bylaw for Local Authorities (The Discharge of Industrial Wastes into the Sewage System), 1981.

This Bylaw is centred on the basic prohibition to discharge industrial waste into sewage systems, unless with a permit or in a manner which does not cause damage to the sewage system, or which does not constitute a public nuisance. Permits are granted if the conditions set out in the Annex are satisfied. The latter lists the substances which are not considered industrial waste. An occupier of a plant requiring a permit shall pay the local authority a fee.
