Nays: 1 (Heimerl) <br />Motion carried. <br />6. Water Service Presentation and Discussion (continued) <br />Mr. Culver presented information on the City's water distribution system, initially <br />prompted by the City Council's charge for the P WETC to review current ownership <br />and maintenance policies of the City of Roseville, and their recommendation <br />related to that ownership between the public system and private service connections <br />to that public system, based on current City Code. <br />Mr. Culver highlighted different elements of a typical water distribution system via <br />a graphic showing a typical layout, and reviewed current ownership delineations <br />based on location of the curb stop or valve allowing the City to turn off water to a <br />private building and related ownership of that private service line up to and <br />including the curb stop. Mr. Culver noted the system is the same for a home or <br />business. <br />At this time in Roseville, Mr. Culver reported that the property owner is responsible <br />for maintenance and ownership form the main up to the home, including the curb <br />stop. <br />From a broader perspective, Mr. Culver reviewed the source of Roseville water via <br />the City of St. Paul and large storage tank adjacent to Reservoir Woods from which <br />the City got its water, traversing into Roseville's booster or pumping station <br />charging it into the system for discharge into the City. Mr. Culver displayed a photo <br />inside the booster station, showing 5 pumps, with only one typically used at atime, <br />even though during key usage, 2 pumps may operate, with the remaining pumps <br />built in for capacity and back-up in case of pump failure. As part of the City's 20 - <br />year CIP, Mr. Culver reported that staff was currently studying the current number <br />of pumps and back-ups to determine if some or any could or should be taken off <br />line in the future. <br />Mr. Culver reported on the 1.5 million gallon water tower used for storage as a <br />back-up if something happened with the St. Paul connection requiring needed <br />pressure from this elevated tank or in case power was lost to the pumps allowing <br />the City to still distribute water. <br />At the request of Member Seigler, Mr. Culver reported there was a blade inside the <br />water tower tank that rotated continuously to keep water moving and not freezing <br />inside the tank, even though that was infrequent due to the size of the tank. Mr. <br />Culver noted there had been some experience in the past with extended cold <br />periods with service freeze and chunks of ice damaging tanks in some communities, <br />and therefore, the blades had been added in the Roseville tank to circulate that <br />water. While some of the water moves into the system, Mr. Freihammer reported <br />that while connected to the system, recharge time varied but continuously circulated <br />and was replaced accordingly. <br />Page 14 of 18 <br />
