A. All cross-connections between any reclaimed water system, on the one hand, and any private water supply or the municipal potable water supply of the city (as that term is defined in WAC 246-290-010), on the other, are prohibited, regardless of whether or not such cross-connections are controlled by automatic devices, such as check valves, or by hand-operated mechanisms, such as gate valves or stopcocks. In addition to any penalties provided by this chapter, failure on the part of persons, firms, or corporations to discontinue the use of any and all cross-connections and to physically separate such cross-connections will be sufficient cause for the discontinuance of the reclaimed water public water service to the premises on which the cross-connection exists. It is further unlawful to maintain any plumbing or arrangement or interconnection whereby, in the judgment of the director, the city potable water supply system either on or off the premises may be contaminated.

The director shall cause periodic inspections of premises served by the Lacey municipal potable water supply system to be made to check for the presence of cross-connections. Any cross-connections found in such inspection shall be ordered removed by the director. If any immediate hazard to health is caused by the cross-connection, potable water services to the premises shall immediately be discontinued until it is verified that the cross-connection has been removed and the hazard abated.

B. Where both reclaimed water and potable water are supplied to a reclaimed water use area, a reduced pressure principle backflow prevention device or an approved air gap separation shall be installed at the potable water service connection to the use area. (Ord. 1294 §1, 2007).
