§ 73-30. Preliminary treatment of certain sewage.

The admission into the public sewers of any waters or wastes having a five-day biochemical oxygen demand greater than 300 parts per million by weight or containing more than 350 parts per million by weight of suspended solids or containing more than 15 parts per million of chlorine demand or containing any quantity of substances having the characteristics above the previously described limits or having an average daily flow greater than 2% of the average daily sewage flow of the town shall be subject to the review and approval of the Town Engineer.
