Each industry for which estimated charges for use of the Town wastewater facility will exceed $1,000 per year shall install a suitable device for continuously recording the flow discharged into the Town wastewater facility. Plans for complete metering installation shall be submitted to the Water Pollution Control Authority for approval.
In the case of industries for which the total annual charge for use of the Town wastewater facility is estimated to be less than $1,000, the volume of flow used in computing charges shall be based upon metered water consumption.
In the event that evidence is presented indicating that more than 20% of the total volume of water used for all purposes does not reach the sewer, an estimate will be made of the proper amount to be deducted.
Where industries have a private water supply, all or part of which is discharged into the sewer, the amount of such supply or the part thereof discharged to the Town wastewater facility shall be metered and included in the charges made.
Flow in the amount of 50 gallons per employee per day may be deducted from the volume determined in accordance with §§ 172-31 to 172-34 and classified as domestic waste.
All industries discharging into a public sewer shall perform such monitoring of their discharge as the Department of Public Works and/or duly authorized employees of the Town may reasonably require, including installation, use and maintenance of monitoring equipment, keeping records and reporting the results of such monitoring to the Water Pollution Control Authority. Such records shall be made available upon request to other agencies having jurisdiction over discharges to the receiving waters.
The rates, as established by §§ 172-26 to 172-30, are intended to defray the cost of pumping, conveying and treating industrial water and shall prevail until such time as they are found to substantially exceed or yield substantially less than the actual cost of service rendered.
