Minutes of the Regular Council Meeting, February 29, 1988 Page 6 WATER TWR. (Cont'd) Christoffersen did not recall when discussions were held regarding the need for a watermain on Hamline Avenue; he major' issue became the water tower and he apologized if he had not this matter with the current Councilmembers. He stated the need for the on Hamline Avenue was to fill the tank. . noted the discussed watermain The Engineer indicated that one method of resolving this matter would be installation of a watermain and booster station on Hamline Avenue; estimated at approximately $100,000.00. Christoffersen also advised a review could be done to determine whether or not an overflow valve could be installed in the Roseville water tower, with the controls on the Arden Hills water tower; when the Roseville tank was filled, the pumps would continue to run until the Arden Hills tank was full. He estimated the cost for installation of the overflow valve would be approximately $25-30,000.00. Christoffersen advised the tank currently is low approximately 120,000 gallons. He stated that the tank should be at full capacity in the summer months, but not necessarily in the winter months. The Engineer stated, in 1986 when Arden Hills was proposing to build the water tower, he recalled advising the Council it would be a "bare bones" tank. He explained the specifications would not include extras, such as clearing and grubbing, sodding and restoration, as it Was determined it could be done more reasonably by City staff. Christoffersen also noted that paving and some of the controls were not included. . In conclusion, Christoffersen offered the following solutions: 1. Installation of watermain and booster station on Hamline; he recommended this should not be accomplished until Hamline Avenue is improved by the County. He stated this would be the more expensive alternative. 2. Request an overflow valve be installed in the Roseville water tower, and the controls be installed in the Arden Hills tower. Mayor Woodburn commented that the Roseville pressure and volume drop was more than anticipated; he questioned if anything had to be done to the tank at the present time or if it could wait until our population increases. Christoffersen stated that was correct, the matter could be accomplished in the future. Councilmember Hansen stated that the Village paid for a million gallon water tower and does not have one; she did not recall the Engineer ever discussing the need for the watermain installation. She stated it was discouraging to have to expend more monies to correct the problems when the Village has slready paid for a million gallon tank. . The Engineer advised that the watermain on Hamline was discussed, however, the need for the water tank became the major issue over the years and the need for the watermain was not emphasized. He noted the construction costs for the water tower came in below the original figure. Hansen questioned if the monies included engineering fees; Christoffersen advised it did not. Councilmember Winiecki questioned if the cost would be lessened if the control valve had been installed at the time of construction; also if the tower was constructed on the basis of the 1967 report. Christoffersen advised the valve could have been installed during construction, however. they were not certain that it would have corrected the problem. He stated the cost would have been the same. The Engineer stated that the tank was built on the basis of the 1967 report, with an upgrade on the volume need; after review of the needs and population, it was determined a 1 million gallon, rather than a 1.5 million gallon tank could be constructed. . There was Council discussion relative to whether or not the problem should be corrected at this time.
