J~ Elk River -~= Municipal Utilities 13069 Orono Parkway • P.O. Box 430 Elk River, MN 55330-0430 September 5, 2007 To: Elk River Municipal Utilities Commission Jerry Takle Jerry Gumphrey Jim Tralle From: Bryan Adams Subject: Maintenance Issues Phone: 763.441.2020 Fax: 763.441.8099 In the process of constructing our proposed 2008 capital budgets, we found some maintenance items that should be addressed. These items are building roof inspections, substation maintenance and water treatment plant electrical inspections. The roofs of our operations area and six water treatment plants have not been recently inspected and we know we have leak issues at two of our treatment buildings. McDowell Company will inspect and provide a report and necessary cost estimates for $979.00. This is part of a roof management program they offer. Staff recommends we do this inspection on an annual basis. We have been building substations on a regular basis but have been poor at doing annual maintenance. We are proposing to use Utility Plus in Elk River to do a complete substation maintenance program at a cost of approximately $15,000 per substation. With seven substations, we are proposing to do one substation per year. This will include 69KV circuit breaker, inspection and testing, transformer and LTC testing, inspection and filtering oil, re-closure inspection testing and lubricating. We are proposing to start this program late this fall. In the water department, we perform maintenance on one well per year resulting in a seven year cycle at an approximate cost of $25,000/year. Unfortunately we have never looked at the electrical panels in the filter plants. Due to the wet conditions and presence of chlorine and fluoride, both very corrosive, the condition of the electrical gear and protective system is in question. Dymax, a St. Paul company is proposing to do a complete inspection, lubrication, verify connection, check trip devices and clean electric gear in all seven facilities at a cost of approximately $12,500. Staff recommends this work be initiated late this fall.
