SPS 382.41 SPS 382.41 Cross connection control.

SPS 382.41(1) (1) Scope. The provisions of this section set forth the requirements for the protection of water within water supply systems when and where there is the possibility of contamination due to cross connections or backflow conditions.

SPS 382.41 Note Note: The Department of Natural Resources governs the operation and design of community water systems and under s. NR 810.15 (1) requires the supplier of water to develop and implement a comprehensive cross connection control program.

SPS 382.41(2)(a) (a) All methods, devices, and assemblies intended to protect water supply systems from cross connections shall be of a type recognized and approved in accordance with ch. SPS 384 and as described in sub. (4).

SPS 382.41(2)(b) (b) All methods including barometric loops and air gaps intended to protect water supplies relative to cross connection or backflow shall be constructed of materials suitable for water supply systems in accordance with ch. SPS 384.

SPS 382.41(3) (3) General requirements. Water supply systems and the connection of each plumbing fixture, piece of equipment, appliance or nonpotable water piping system shall be designed, installed and maintained in such a manner to prevent the contamination of water supplies by means of cross connections.

SPS 382.41(3)(a) (a) Types of cross connection control.

SPS 382.41(3)(a)1. 1. Water supply systems shall be protected against contamination due to cross connections or backflow conditions by one of the methods or devices specified in Table 382.41-1 depending upon the situation or Table 382.41-2 depending upon the specific application or use, and the limitations specified in sub. (4).

SPS 382.41(3)(a)2. 2. For the situations described in par. (b) 3., cross connection control shall be provided as part of the fixture fitting outlet or in the water supply piping for the fixture fitting outlet.

SPS 382.41(3)(b) (b) Classifications. For the purposes of this section:

SPS 382.41(3)(b)1. 1. The designation of a high hazard or low hazard situation shall be determined on the basis of how a toxic or nontoxic solution is intended or recommended by the manufacturer of the solution to interface with the potable water supply system.

SPS 382.41(3)(b)2. 2.

SPS 382.41(3)(b)2.a. a. A continuous pressure situation shall be considered to exist when a pressure greater than atmospheric within the water supply system exists for more than 12 continuous hours.

SPS 382.41(3)(b)2.b. b. A noncontinuous pressure situation shall be considered to exist if the conditions in subd. 2. a. do not occur.

SPS 382.41(3)(b)3. 3. A high hazard cross connection situation shall be considered to exist for a connection of the water supply system to:

SPS 382.41(3)(b)3.a. a. Any part of the drain system; and

SPS 382.41(3)(b)3.b. b. Any other piping system conveying water from nonpotable sources, including but not limited to lakes, rivers, streams or creeks.
