Item No. 7I Type of Business: CB WK: Work Session; PH: Public Hearing; CA: Consent Agenda; CB: Council Business City of Mounds View Staff Report To: Honorable Mayor and City Council From: Greg Lee, Director of Public Works Item Title/Subject: 2002 Well Rehabilitation Project Resolution No. 5872 Waive Public Improvement Hearing Order the Project Authorize the preparation of Plans and Specifications Meeting Date: October 28, 2002 Background: The City of Mounds View has a total of six wells, with one of the wells (well number 4) out of commission since 1992 due to poor water quality. To properly maintain the wells, the pumps and other equipment must be periodically evaluated, inspected, and repaired or replaced. The City established a maintenance program whereby the wells would be evaluated and rehabilitated on a seven-year cycle. A longer period of eleven years was tried; however, it was discovered that this period was too long to identify minor problems and correct them before they became major replacements. Discussion: Wells Number 1 and 2 were last rehabilitated in 1995. Based on the seven-year evaluation schedule, they are therefore due for rehabilitation this year. Wells Number 3 and 5 were last done in 1997 and are scheduled for rehabilitation in 2004. The 2002 adopted budget has a total of $30,000 for well inspection and preventative maintenance. Typically, this is the amount needed to rehabilitate one well. Past practice has been to rehabilitate two wells per contract. Economy of scale is realized due to the reduced cost of administrating two separate projects. A larger project also improves the possibility of receiving favorable bids. Given this, staff recommends that two wells be rehabilitated in 2002. To fund the additional well, staff recommends that funds from the water repairs account (700- 4823-5150) be utilized. A line item exists in this account for the water tower
