The Water Utility will charge for each meter a rental charge set by the Water Utility to compensate for the cost of furnishing and servicing the meter. The rental charge shall be billed at the time the sewer service charge is billed.
C. 
Deduct meters. If a user feels that a significant amount of metered water does not reach the sanitary sewer, a customer may avail himself of one of the following options:
(1) 
He may request the approving authority to have such additional meters or metered services installed as are necessary to calculate the volume of water not discharged to the sanitary sewer (i.e., a "deduct" meter), or he may request the approving authority to have a meter installed to measure the actual amount of sewage discharged to the sanitary sewer (i.e., a "sewage" meter). Requests for a second meter or metered services must be made, in writing, to the approving authority. In the event the approving authority agrees to such installations, the customer shall be charged all costs attendant thereto, including, but not limited to, a meter yoke for each meter (to be installed by a licensed plumber); meter rental (the meter will be owned by the customer and subject to access and inspection by the City personnel at all times) in an amount set annually by the approving authority; remote reading device(s) if necessary; and labor and miscellaneous parts and supplies. No provision shall be made, nor shall any means be taken, to route water from any deduct meter to the customer's general distribution system. In addition to the general penalties set forth in § 5-2-9, any violation of this chapter will result in nullification of the deduct readings and removal of the deduct meter.
(2) 
In the event it is physically impractical or impossible to install metering equipment, he may request the approving authority to take such means as it deems necessary to formulate an estimate of the amount of water not being discharged into the sanitary sewerage system or, conversely, the amount of actual sewage discharged thereto.
