(A) The admission into public sewers of any substances, materials, waters, or waste described in this chapter, or of water or waste having an average daily flow greater than 5% of the average daily sewage flow of the city shall be subject to the review and approval of the city. Where necessary in the judgement of the city, the owner shall provide at his or her expense any preliminary treatment necessary to reduce the objectionable characteristics or constituents to within the maximum limits provided for in § 50.019 or to control the quantities and rate of discharge of the waters or wastes. Plans, specifications, and other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the city and the state, and no construction of such facilities shall be commenced until approval is obtained in writing.
(B) Where preliminary treatment facilities required under this section are provided for any water or wastes, they shall be maintained continuously in satisfactory and efficient operation by the owner at his or her expense. When required by the city, the owners of any property served by a building sewer carrying industrial waste shall install suitable control manholes in the building sewer to facilitate observation, sampling, and measurement of the waste. The manholes, when required, shall be accessible and safely located and shall be constructed in accordance with plans approved by the city. The manholes shall be installed by the owner at his or her own expense and shall be maintained by him or her so as to be safe and accessible at all times.
