913.03 SEWER RENTAL CHARGE; COMPUTATION AND RATE.
   For the purposes provided in Sections 913.01 and 913.07, there is levied a charge or rental to be paid by every person, firm or corporation whose lots, lands and premises are served by a connection, directly or indirectly, to the sanitary sewerage system, or otherwise discharging sanitary sewage, industrial wastes, water or other liquids, either directly or indirectly, into the Village sanitary sewage system, a charge or rental payable and collectible as hereinafter provided and in an amount determinable as follows:
   (a)   Except as herein provided, sewer charges or rentals shall be based upon the water consumed on the premises served by a connection, directly or indirectly, to the sanitary sewerage system, as measured by the Village water meter or meters used thereon. In the event water used upon any such premises is derived from a source other than or in addition to the Village water supply, measurement or estimation thereof and a determination of the percentage of such water which is self-produced or otherwise obtained and which is discharged into the sanitary sewer system shall be made by the Village Engineer and shall be the basis of computing the sewer rental charge. In case of a disagreement as to the amount, the owner or other interested party may, at his own expense, install and maintain a meter acceptable to the Board of Public Affairs for such purpose.
      In the event that a premises is served both by the Village water supply and a properly metered self-producer's supply, the rates or charges shall be computed by combining the consumption of both sources of supply.
   (b)   In any case where industrial wastes or other liquids discharged into the sanitary sewer system, either directly or indirectly, are not susceptible to meter measurement, such wastes or other liquids shall be measured or estimated in such manner as the Village Engineer shall determine in order to establish the sewer rental or charges therefor, except that rain water discharge directly or indirectly from roofs into the sanitary sewerage system shall be charged for in accordance with the provisions of subsection (d) hereof.
   (c)   Sewer charges or rentals shall be twenty-five percent (25%) of the gross bill charged by the Village for water passing through a Village water meter; or in respect to premises being supplied from sources other than or in addition to the municipal water system, twenty-five percent (25%) of the amount which would have been charged for water consumed and discharged in the sanitary sewage system, measured as herein provided; if such water had been supplied by the Village. In no event shall sewer charges or rentals be less than twenty-five percent (25%) of the monthly minimum water rental as now or hereafter charged by the Village.
      (Ord. 1984-14. Passed 1-16-84.)
   (d)   No person shall permit roof water to be discharged into the sanitary sewer system of the Village directly or indirectly from any residence, commercial, industrial, public or semipublic building or any roof whatsoever.
      (Ord. 73-52. Passed 5-7-73.)
   (e)   In the event that water supplied from the Village water system to large consumers is used for such purposes that it will not be returned to the sanitary sewerage system, that portion not returned shall be exempt from the sewer charges or rentals, provided the user, at his own expense, furnishes, installs and maintains suitable metering devices acceptable to the Village Water Department for the determination of the same.
