DRAFT - Water Treatment System Needs Assessment September 2016 P05367-2015-000 50 CHAPTER 8 CONCLUSIONS AND RECCOMENDATIONS The goal of this assessment was to review the process, mechanical, electrical, and controls for all of Mounds Views water treatment infrastructure and construct a plan for Mounds View to follow that would responsibly and efficiently assist them in re-investing in these facilities. This plan will ensure that the City of Mounds View is equipped with a reliable and robust treatment system for years to come. The City of Mounds View currently has adequate water supplies to provide clean drinking water to its residents for the foreseeable future, but this assessment indicated many areas where the treatment infrastructure is nearing the end of its life and could be improved. All three water treatment facilities are nearing 25 years old. Two of the treatment facilities have already undergone one round of tank rehabilitation. Most of the control panels that operate these systems are obsolete and parts are no longer available. AE2S would recommend that Mounds View begin to plan for the replacement of portions of these systems. 8.1 Proposed Improvements Based on the review of WTP’s No. 1, No. 2, and No. 3, the Booster Station and Wells 1-6 the following observations were made. Improvement No. 1: WTP No. 2 is at the end of its life and is should take priority for rehabilitation. The suggested timeline for this rehabilitation would be sometime in the next 1-2 years but can be adjusted to accommodate City priorities. The costs and needs that were addressed in chapter 4 can either be done in small pieces or as a larger project. Because WTP No. 2 has multiple items that are in need of replacement it may be more cost effective to complete these improvements as one large project. The estimated cost to completely rehabilitate WTP No. 2 is $1,601,600. Mounds View should also budget for an additional $300,000 in engineering services when they decide to undergo rehabilitation of WTP No. 2. The detailed estimate for this project is included in Appendix D. Improvement No. 2: Mounds View’s control panels are in need of replacement. Many are utilizing equipment that is no longer available. Figure 8.1 below summarizes the anticipated costs to replace/rehabilitate these control panels and a suggested timeline to accomplish these improvements. The total estimated costs for these improvements is shown in Figure 8.1 and is approximately $482,000 (2016 dollars). Most of these improvements could be completed in the next 2 years but the well No. 1 and No. 2 control panel improvements could be scheduled for 5 years. Control panel replacement can be done in conjunction with process improvements. If Mounds View decides to rehabilitate WTP No. 2 the controls for that facility would be completed at that time and is already included in the $1.6M estimate for that project.
