City Council Meeting Minutes September 17 2019 Page 7 of 8 DISCUSSION/DIRECTION/ACTION — CONTRACT BETWEEN THE CITY OF LOUISVILLE AND GLACIER CONSTRUCTION CO , INC FOR THE CONSTRUCTION OF AND THE APPROVAL OF CONSTRUCTION MANAGEMENT SERVICE ADDENDUM FOR THE SID COPELAND WATER TREATMENT PLANT ON -SITE CHLORINE GENERATION IMPROVEMENTS PROJECT Public Works Director Kowar stated this a discretionary project to modernize the water disinfection system in the water treatment plant. New plants do not use this process The treatment facility does not have chlorine gas scrubbing systems for the chlorine gas systems which is a current Colorado Department of Public Health and Environment (CDPHE) design guideline and CDPHE is likely to require chlorine gas scrubbing improvements in the next five years These improvements are estimated to cost as much or more than converting now Sodium hypochlorite is safer to use than chlorine gas for employees and the surrounding area and sodium hypochlorite is cheaper than chlorine gas There is not initial cost savings but it is cheaper operationally He noted the City already made this upgrade at one treatment plant. This is a long term improvement. Staff recommends approval of the contract with Glacier Construction Co in the amount of $682,300 for an onsite chlorine generation system at the Sid Copeland Treatment Plant. In addition, staff recommends approval of a contract addendum with Mott MacDonald for construction management services for this project. This requires a $450,000 budget amendment which does almost double the cost from the original estimate Staff recommends approval Director Kowar noted the Utility Committee reviewed this project and recommends approval Councilmember Stolzmann, Chair of the Committee, stated this is a safety improvement for residents and staff, it doesn't require an expansion of the building with some good engineering, and it does fall in the budgeted level of the fund balance for the fund Councilmember Maloney added the Utility Committee noted this has a very small effect on utility rates Mayor Muckle stated the current system has not been without some safety issues so this is a good project.
