					 SPS
					 382.41. Water system interconnections are prohibited
					 except as provided in sub. (2). In addition the following requirements shall be
					 met:
(1) CROSS CONNECTION CONTROL
				  PROGRAM. In order to protect the public water supply system, the water supplier
				  for every municipal water system shall develop and implement a comprehensive
				  cross connection control program for the elimination of all existing
				  unprotected cross-connections and prevention of all future un-protected cross
				  connections to the last flowing tap or end-use device. The program may include
				  providing public education materials in lieu of inspections of low hazard
				  portions of residential or commercial facilities. Low hazard areas consist of
				  normal kitchen and bathroom fixtures. The water supplier shall keep a current
				  record of the cross connection control program available for annual review by
				  the department. The cross connection control program shall include:
(a) A complete description of the program and
				  the administration procedures, including designation of the inspection or
				  enforcement agency or agencies.
(b)
				  Local authority for implementation of the program, such as ordinance or other
				  governing rule.
(c) A time schedule
				  for public education materials, surveys and follow up surveys of consumer
				  premises for cross connections including appropriate record keeping. Unless
				  otherwise authorized by the department, water suppliers for each municipal
				  water system shall cause a survey to be conducted for every residential service
				  a minimum of once every ten years or on a schedule matching meter replacement.
				  Public educational materials, when being provided in lieu of low hazard
				  inspections, shall be provided to the customer no less than every 3 years and
				  with every cross connection survey. Unless a detailed alternative schedule is
				  included in the cross connection control program and is approved by the
				  department, water suppliers for each municipal water system shall cause a
				  survey to be conducted for every industrial, commercial and public authority
				  service a minimum of once every 2 years. Commercial properties of similar or
				  lesser risk to residential properties may follow the same schedule as
				  residential properties. Completed survey results shall be maintained by the
				  water supplier until corrections and follow up surveys have been
				  made.
(d) A complete description of
				  the methods, devices, and assemblies which will be used to protect the potable
				  water supply. Compliant methods, devices and assemblies are listed in s.
				  SPS
				  382.41.
(e) Provisions for denial or discontinuance
				  of water service, after reasonable notice, to any premises where an unprotected
				  cross connection exists or where a survey could not be conducted due to
				  denial.
(f) Submission to the
				  department of a copy of an ordinance establishing a cross connection control
				  program, an annual report including a total number of all service connections
				  by category, and a report indicating the number of surveys completed in each
				  category for that year.
