Waters or wastes having (A) five-day BOD greater than 300 parts per million by weight, or (B) containing more than 350 parts per million by weight of suspended solids, or (C) containing any quantity of substances that this title declares may not be discharged into any public sewer, or (D) having an average daily flow greater than two percent of the average daily sewage flow into the sewage treatment plant, shall not be admitted to the sewage works unless the city engineer determines that such waters or wastes will not damage or unduly burden the sewage works and will not constitute a hazard to life or property.
If waters or wastes are inadmissible to the sewage works, the owner shall, at his expense, (A) reduce BOD to 300 parts per million or less, (B) reduce suspended solids to 350 parts per million by weight or less, (C) reduce objectionable characteristics or constituents to within maximum limits provided for by this title, or (D) control the quantities and rates of discharge of such waters or wastes, as necessary. Plans, specifications, and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the city engineer, and no construction of such facilities shall be commenced until the approvals are obtained in writing.
