CHAPTER 36. INDUSTRIAL WASTE, WASTEWATER COLLECTION AND DISCHARGE.

Sec. 36-23. Measuring devices required.

The owner of any premises serviced by a building sewer carrying industrial waste may be required by the director to install a suitable device for continuously recording the flow discharged to the city's industrial waste sewer, together with a suitable control manhole to facilitate observation and sampling of the wastewater. This installation may be required at any time when, in the opinion of the director or the industrial waste inspector, such installation is warranted. Such manhole and measuring device when required, shall be accessible and safely located and shall be constructed in accordance with plans approved by the director. It shall be of such design and construction as to prevent infiltration by ground and surface waters or introduction of slugs of solids to the industrial waste sewer. The facilities shall be so maintained by the person discharging industrial waste that any authorized representative, or employee, of the person discharging industrial waste that any authorized representative, or employee of the city may readily and safely measure the volume or obtain samples of the flow at all times. The manhole and measuring device shall be installed by the applicant at his expense before discharging industrial waste.

The measuring device may be installed on the source of the water to the industrial user if that quantity is to be used as the measurement for the industrial wastewater produced. If sufficient evidence is presented to the director that not all the total volume of water used for all purposes reaches the sewer, an estimate will be made by the director of the proper amount to be deducted to compute the industrial waste flow.

The measuring device shall be installed, maintained and calibrated for accuracy when deemed necessary by the city, at the expense of the industrial user. (Ord. No. 1870 § 3; Ord. No. 2102 (NCS).)
