(A)   No person shall discharge water or cause to be discharged any unpolluted waters such as storm water, ground water, roof run off, subsurface drainage such as that from floor drains, sump pumps, cisterns, field tile or any other recognizable source or any type of private, commercial or industrial cooling water to any sanitary sewer.
   (B)   Any person, firm or corporation having a roof drain system, surface drain system, footing tile, swimming pool, ground water drain system or sump pump now connected and/or discharging into the sanitary sewer system shall disconnect and/or remove the same.  Any disconnects or opening into the sanitary sewer shall be closed or repaired in an effective, workmanlike manner, as approved by the public works supervisor.
   (C)   Dwellings and other buildings and structures which require because of the infiltration of water into basements, crawl spaces and the like, a sump pump system to discharge excess water shall have a permanently installed discharge line which shall not at any time discharge water into the sanitary sewer system.  A permanent installation shall be one which provides for year around discharge capability to either the outside of the dwelling, building or structure, or is connected to the city storm sewer.  It shall consist of a rigid discharge line, without valves or quick connections for altering the path of discharge, and if connected to the city storm sewer shall include a check valve.
   (D)   Powers and authority of inspectors.  Duly authorized employees or representatives of the city, bearing proper credentials and identification, shall be permitted to enter all properties for the purpose of inspection, observation, measurement, sampling, and testing pertinent to determine the nature of discharge into any public sewer or natural outlet in accordance with the provisions of this chapter.  In lieu of having the city inspect their property, any person or entity may furnish a certificate from a licensed plumber certifying that their property is in compliance with this chapter.
   (E)   Any person refusing to allow their property to be inspected or refusing to furnish a plumbers certificate within 14 days of the date the duly authorized city employees or representatives are denied admittance to their property shall be subject to the surcharge hereafter provided for.
   (F)   At any future time, if the city has reason to suspect that an illegal connection may exist in a premises, the owner, by written notice shall comply with the provisions of (C) above.
   (G)   A surcharge of $100 per month may be imposed and added to every sewer billing mailed to property owners who are not in compliance with this chapter.  The surcharge shall be added every month until the property is in compliance.  The City Council may grant waivers from the surcharges where strict enforcement may cause undue hardship unique to the property or where the property owner was scheduled for disconnection but cannot do so due to circumstances, such as availability of the plumber or inclement weather.
