Grease, oil, and sand interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, watertight, and equipped with easily removable covers which when bolted into place shall be gastight and watertight.

(b) A chlorine demand of more than 15 mg/l;
(c) Having any average daily flow greater than 2% of the average daily flow to the village wastewater treatment facility; and
(d) Total phosphorous concentration greater than 12 mg/l.
(2) Preliminary treatment shall be provided, at no expense to the village as may be necessary to reduce the B.O.D. to 300 mg/l and suspended solids to 350 mg/l or to reduce objectionable characteristics of this effluent to within the maximum limits provided for in division (B) above or to control the quantity and rates of discharges of the waters or wastes. On direction of the village, a person may be required to remove, exclude, or require pretreatment of any industrial waste in whole or in part for any reasons deemed to be in the village's interest. Where preliminary treatment facilities are provided for any waters or wastes, they shall be maintained in satisfactory and effective operation at no expense to the village. Plans, specifications, and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for approval to the village and no construction of the facility shall be commenced until approvals are obtained in writing. The village may elect to treat industrial wastes, discharged in excess of normal domestic concentrations on a basis prescribed by written agreement and for an established charge to cover the added cost.
