This chapter establishes the terms and conditions of sewer service and pretreatment regulations to prevent the introduction of pollutants into the treatment facilities which interfere with the operation of the facilities or contaminate the sewage sludge; pass through the treatment works into receiving waters, the atmosphere; and improve the feasibility of recycling and reclaiming waste waters and sludge resulting from waste water treatment.

These regulations shall apply to the collection, treatment and disposal of wastes delivered through collector sewers, into the trunk sewers of the City; to the tapping of the connection to the trunk sewers to the issuance of permits and the collection of fees; to the imposition and collection of fees to pay the cost of checking plans, inspecting construction and providing "as-built" plans of the facilities; and to penalties for violation of these provisions.
