rll ---\.) ( ); tli{ **Item 3.6.** River MEMORANDUM TO: Pat Klaers City Administrator FROM: Darrell Mack WWTF Superintendent DATE: June 22, 1999 SUBJECT: Emergency Power Supply For Lift Stations . Mter meeting with utilities manager Bryan Adams, it appears that in a major power outage the utilities generating facility will be able to supply power to the wastewater treatment facility. The generating facility would not be able to supply power to any lift stations except on a four hour rotation, which is not often enough to prevent sewage backups. To keep the collection system from backing into homes we need four additional generators. Three generators would be set up at stations that cannot be down for any length of time and one generator would be used to keep the rest of our stations pumped down. The following quotes were received with Ziegler Power Systems being the lowest: Ziegler Power Systems $57,430 Katolight $59,300 Cummins North Central $64,118.40 Long Lake Tractor $90,210 (price does not include sales tax) Used New New New Even with Ziegler quoting used generators, I feel they are a best buy for a couple of reasons: 1) they have been checked out and repairs were made if they were needed, 2) they are set up for all 3 voltages that we have in Elk River, which makes them a lot more versatile and can be used at other locations. The other generators that were quoted can be wired for all 3 voltages, but at an additional cost. . Because no single generator is over $25,000, we do not have to go through the bid process. Therefore, it is my recommendation to purchase the generators quoted by Ziegler Power Systems. 13065 Orono Parkway. P.O. Box 490 · Elk River, MN 55330. TDD & Phone: (612) 441-7420. Fax: (612) 441-7425
