Any person discharging or desiring to discharge an industrial waste mixture into the sewerage works of the city, or any sewer connected therewith, shall provide and maintain in a suitable accessible position on his or her premises, or such premises occupied by him or her, an inspection chamber or manhole near the outlet of each sewer, drain, pipe, channel or connection which communicates with any sewer or sewerage works of the city or any sewer connected therewith. Each such manhole or inspection chamber shall be of such design and construction as to prevent infiltration by ground and/or surface waters and to prevent the entrance of objectionable slugs or solids (greater than one-half inch in size) into the sanitary wastewater system. The inspection chamber shall be maintained by persons discharging waste so that any authorized representative or employee of the city may readily and safely measure the rate of flow and obtain samples of the flow at all times. Plans for the construction of control manholes or inspection chambers, including such flow measuring devices as may be required, shall be approved by the approving authority prior to the beginning of construction. Such structures and equipment (including a valve on the effluent line) shall be installed by the person at his or her expense.
