<br />These interconnections are normally closed but can be opened to meet the City of <br />Roseville's emergency needs. Appropriate personnel are to be contacted before these <br />connections are opened so operational changes can be implemented in the Source City if <br />necessary. <br /> <br />The interconnections with the cities of Little Canada, Lauderdale, and St. Paul are only <br />of use in emergency situations related to the Roseville distribution system. The source <br />water for these connections is from the City of St. Paul system and would be of little <br />value during an emergency within the St. Paul Water Utility production and treatment <br />systems. <br /> <br />The interconnections with Shoreview, St. Anthony, and New Brighton could be opened <br />in a wider variety of emergencies as they produce their own water from wells within <br />their system. <br /> <br />For emergency power, Roseville's water pumping station is equipped with an <br />emergency diesel generator capable of rumring up to 3 pumps simultaneously. It <br />automatically switches on in situations of power failure from the NSP service. It will <br />also shut down automatically upon restoration of power to the NSP service. The <br />resulting effect of power failure is unnoticeable to water consumers in the Roseville and <br />Arden Hills systems. <br /> <br />A map of these interconnections is included in Appendix B at the end of this report. <br /> <br />SECTION D. Demand Reduction Procedures <br />Water Usage Restrictions, Section 801.19 of the Roseville City Code, empowers the City <br />to establish emergency water use restrictions when necessary. A copy of this section is <br />included in Appendix A These restrictions can be set forth by the City councilor, as <br />required by our wholesale water contract, by the St. Paul Water Utility. Generally, <br />demand reduction procedures will directly follow the procedures as outlined in the St. <br />Paul Water Utility water conservation and emergency response plan. <br /> <br />SECTION E. Procedures for Water Allocation <br />During periods of linrited water supply, public water suppliers are required to allocate <br />water based on the following priorities established in Minnesota Statutes Section <br />103G.261. <br /> <br />First Priority--Domestic water supply, excluding industrial and commercial uses of <br />municipal water supply, and use for power production that meets contingency <br />requirements. <br /> <br />Page 8 of 22 <br />
