City of Orono, Minnesota
The City of Orono operates two separate water systems consisting of the north and south system. The north system is comprised of a well, well house, and water tower. The south system is comprised of two wells, a water treatment plant, and a water tower. Both systems have interconnects with adjacent municipalities. The north system well house and south system water treatment facility needed improvements.
Bolton & Menk completed preliminary analysis of both systems, including hydraulic analysis to determine several water interconnects could be removed as they were redundant and only added extra cost and confusion to the water systems. Final design phase improvements consisted of modifying and improving chemical feed systems, valve replacements, piping replacements, new coatings, HVAC improvements, and electrical and control improvements.
The chemical feed improvements met Minnesota Department of Health requirements and design standards and improved operator safety. All of these upgrades improved the operation and maintenance of both facilities.
