When required by the city, each user shall install a suitable measuring, sampling and analyzing device. The city may not require installation of the devices where the city determines that the industrial user has concentrations of BOD and suspended solids no greater than the concentration of the constituents in the general municipal flow and a satisfactory method and access exist for sampling and determining the total daily sewage flow. In these cases, the charges to those industrial users shall be based on the flow rate as determined and on BOD and SS loads equal to the average load of the general municipal flow. Each industrial user required by the city to install and maintain sewage monitoring facilities shall submit to the city a monthly report of daily flow, BOD and SS on a form approved by the city. This report shall be used for billing purposes and shall be submitted prior to the fifteenth day of the subsequent month. The city has the right, periodically or continuously, to inspect the monitoring facilities, to measure, sample and analyze the user’s flow and to analyze the samples obtained by the industrial user. In the event of any discrepancy between the flows or loads determined by the city and the industrial user, the values determined by the city shall be used for billing purposes.
