ORONO COUNCIL MEETING HELD SEPTEMBER 10, 1990 ZONING FILE #1516- MACMILLAN CONTINUED • approve the proposed easement with the exception that only a 3 /5ths vote be required. Nettles asked Barrett whether this agreement will change the legal powers of the City in any way. Barrett replied, "In my opinion, it will not." Motion, Ayes -3, Goetten, Nettles, Nay. Motion passed. MAYOR /COUNCIL REPORT: None. ENGINEER'S REPORT: CHANGE ORDER 12, WELL #3 Bernhardson reported that a flow rate for well #3 has been established in the range of 1,200 to 1,600 gallons /minute. He said, "However, there has been a problem with loose sand under the bedrock accumulating at those rates. Continuous pumping at those rates of 500 gallons per minute would provide a continued flow free of sand, but starting and stopping the pump would cause about a minute of sand to accumulate. This would not be desirable over a long period of time. This is the appropriate time to try to eliminate the sand entirely. We are recommending approval of change order #2 to accomplish that. Mr. Dick Foster of Bonestroo is present this evening to answer any questions." Goetten questioned whether the additional costs will be passed on to the users of well #3. She said, "Well #3 has been • brought before us several times now and is becoming increasingly more expensive." Bernhardson agreed with Goetten, but stated that this is the first change order that has been presented to Council for well #3. He said, "We will assess all of the costs of this to the benefiting property owners, either through assessment or connection charges. We could also add user revenue to assist with the costs." Callahan asked if well #3 will serve the location proposed for the new facilities. Bernhardson replied in the affirmative. Mr. Foster said. "It is unusual for these circumstances to occur. This area is right on the edge of the bedrock formation. A lot of lakeshore wells are drilled in the Jordan and limestone formations. As you approach the Orono School those formations are gone and it is necessary to drill deeper for water. We were fortunate in this case to find Jordan formations. The well does have a very good yield. The problem is that there isn't enough cavity. We need to enlarge and stabilize the cavity. The change order reflects our estimated cost to do that. The estimate is on the high side. In our opinion, it is better to invest the • additional money now to make the well efficiently functional. - 21 -
