To prevent the siphoning of water from a structure back into the municipal water system when it becomes necessary to disrupt water service and to prevent damage to customer’s property caused by such siphoning, all customers applying for new water service and all customers presently serviced may be required in the discretion of the Utilities Superintendent to have placed on the line a swing valve (backflow prevention device) of such size and at such location as is approved by the Utilities Superintendent. If a present customer is required to place a swing valve on his or her line, the Municipal Clerk or Utilities Superintendent shall give the property owner notice by personally serving written notice or by registered letter or certified mail, directed to the last-known address of such owner or the agent of such owner, directing the placement of such swing valve. If within 30 days of mailing or giving such notice, the property owner fails or neglects to cause such placements to be made, the Utilities Superintendent may cause such work to be done and assess the cost upon the property served by such water line. Reasons for requiring swing valves includes, but is not limited to, installation of an underground sprinkler system, installations or replacement of a water heater, and installation or replacement of a water softener.
