Commercial/industrial rental units.

A. Rental units shall include all churches, schools, motels, hotels, institutions, stores, and commercial, industrial and other nonresidential establishments. The number of applicable sewer units shall be determined by dividing the annual water consumption on said premises by 60,000 gallons. Each of said premises, however, shall constitute a minimum of one rental unit. Any sewer user whose sewer rent is based on annual water consumption may elect to measure the actual amount of its sewage discharge into the sewer system. All measuring devices, equipment, sub-meters, and installation shall be installed at the sewer user's expense in accordance with the Town of Webster Sewer Department's specifications, inspection and approval.B.

The water flow from a sub-meter will be subtracted from the total water consumption in order to calculate the correct amount discharged into the sanitary sewer system. All flow measuring devices shall be calibrated annually at the owner's expense. All expenses incurred by the Town at any time in connection with its inspection and approval of such installations which relate to measurement of sewage discharge into the sanitary sewer system shall be reimbursed to the Town by the sewer user upon notice thereof.
