(A) Where required by the city, the owner of a property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters and other appurtenances to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with approved plans. The plans detail the location and type of manhole, meter, flume and other appurtenances deemed necessary by the city shall be submitted for review to the city. The manhole shall be installed by the owner at his or her expense, and shall be maintained by him or her so as to be safe and accessible at all times.
(B) The preferred location of the control manhole shall be outside of any building structure so as to be more accessible. If locks are place on the entrance to the manhole structure, the owner shall provide the city with a key.
(1) Where required by the city, other users who discharge or could potentially discharge greater than normal domestic strength wastewater to the public sewer shall provide a monitoring location, sampling equipment or other appurtenances that are deemed necessary by the city to characterize the quantity and strength of the wastewater discharged to the public sewers. The required flow monitoring equipment and other appurtenances specified by the city shall be installed by the owner at his or her expense, and shall be maintained by the owner so as to be safe and accessible at all times.
(2) A maintenance schedule of flow monitoring and sampling equipment must be accepted by the city. All maintenance and equipment repair shall be performed within a reasonable time as determined by the city. Failure to perform maintenance within a reasonable time shall be subject to the same forfeiture and procedural provisions as applied to violations under the sewer use ordinance. Prior to completion of satisfactory repairs, and for any preceding period during which the city determines there existed a malfunction, error or bias in the metering and sampling, the volume and strength of the wastewater for that period of discharge shall be based on historical data and a reasonable engineering estimate of flow and strength, taking into account materials and known production variations and the like. All such factors shall be determined by the city in consultation with the discharger. If prolonged periods of breakdown are anticipated, approved interim measuring and sampling needs shall be provided, and used to determine the volume and strength of wastewater.
(C) Following approval and installation of permanent or temporary metering or sampling equipment, such equipment shall not be removed without the consent of the city.
