All persons discharging or depositing wastes into the public sewers shall pay a sewer service charge proportional to the liquid volume of waste so deposited, which charge shall be collected as a sewer rent.
All persons discharging or depositing wastes with concentrations in excess of the pollutant concentrations in normal sewage and depositing inflow per Sec. 27-43 shall pay a surcharge. This surcharge shall be 1.5 times the rate set for normal sewage as set per Sec. 27-180.
The service area of the POTW may be segmented to assist in a fair distribution of user charges, especially if there is a pump station serving a segment.
The volume of flow to be used in computing sewer service charges and abnormal sewage surcharges shall be based upon metered water consumption as shown on the records of meter readings maintained by the City of Olean Water Department. In the event that a person discharging wastes into the POTW produces evidence to the Superintendent demonstrating that a substantial portion of the total amount of metered water does not reach the POTW, then the Superintendent shall either establish a percentage of the total metered water to be used as a basis for such computations, or direct the installation of appropriate flow measuring (and totalizing) devices to measure and record the actual amount of flow into the POTW. In the event that a person discharging wastes into the POTW procures all or part of his water supply from unmetered sources, the Superintendent shall either direct the installation of water meters on the other sources of water supply, or direct the installation of appropriate flow measuring devices to measure and record the actual amount of flow into the POTW. Any water meters and/or flow measuring devices installed pursuant to this section shall be of a type and design acceptable to the Superintendent and shall be installed, maintained, and periodically tested as required by the Superintendent, at the owner's expense. All such meters and/or flow measuring devices shall be subject to periodic inspection, testing, and reading by the Superintendent. Any person discharging wastes into the POTW may install a flow measuring device at his option, of the type, design, installation, and maintenance standards of the Superintendent, at the owner's expense.
