MINUTES OF THE ORONO CITY COUNCIL MEETING Monday, February 10, 2014 7:00 o’clock p.m. _____________________________________________________________________________________ Page 25 of 30 (11. WATER SYSTEM STUDY/WATER SYSTEM MODELING – PRESENTATION, Continued) Martini stated in evaluating the components of the systems, they made some recommendations as far as improvements. Martini noted the Navarre system is basically built out with not a lot of growth potential. A new well is recommended for the Highway 12 system since it basically runs 24 hours a day and is taxed out at the high demand times. Martini indicated a new well would increase the capacity of the system and provide that firm capacity and redundancy that is recommended. From an improvements standpoint, Martini indicated they have identified $278,000 worth of improvements for the Navarre system since those components are getting toward the end of their useful life. In addition, there are some humidity issues in the plant so some dehumidifiers are recommended. Martini indicated for the most part the replacement of the items is due to age issues. As it relates to the Highway 12 system, that is estimated to cost $671,000, with the biggest cost associated with the new well and piping. Martini stated from a storage standpoint, the Navarre system is pretty well built out at this time and no storage improvements are recommended. On the Highway 12 system, some storage improvements will need to be added at some point in the future due to the potential growth in that area. Martini noted water pressures are reasonably adequate on all systems. The available fire flow generally meets industry standards throughout the system but along Wayzata Boulevard there are some improvements that would be recommended at the time the roadway is improved, including the replacement of an 8-inch pipe with a 12-inch pipe as well as some water main extensions. The total estimated cost for the distribution improvements is $694,000. The majority of those costs is related to the expansion and would likely be development driven. McMillan asked what costs the City would need to incur as part of the turnback of Old Highway 12. Martini stated to his recollection replacing the 8-inch pipe with the 12-inch pipe was approximately $80,000. McMillan asked if the extensions are outside of the curb cuts. Martini indicated they are. Struve stated some of the extensions are planning for future growth. McMillan asked if those would be development costs. Struve indicated that is correct. Martini stated the combined water systems of Long Lake and Orono are able to meet the maximum day- to-day demands. In an emergency situation, the City does have those interconnects but since they are intended for an emergency situation only, a new well for the Highway 12 system is being recommended. Martini noted if improvements are conducted on the Highway 12 well, fire protection flows will be reduced. McMillan asked if the City would need to pay for water from Long Lake during that time.
