Table 10.2 Future studies Study Topics Reason Priority Study 1 Water quality analysis to This may be a deal breaker if mixing waters of High Water Quality define the impacts of mixing differing qualities results in unacceptable Analysis filtered water from Circle Pines impacts with unfiltered water from other communities Specific objective: Consider alternate alignment This grouping includes communities that receive High to capture proximity and filtered water It reduces the likelihood of What is the existing relationships such as unacceptable impacts resulting from mixing correct a group including Blaine. dissimilar water It also leverages cities that combination of Circle Pines and Lexington already share water regularly (Blaine and cities for a joint Consider if Columbus should Lexington) utility be included at all If so when Study 2 Distribution system model of Create a tool needed to perform the study Medium Facility Plan all communities to be joined together Specific Storage facility siting Use of existing storage to benefit growing Medium Objective: communities is a key benefit to joining the Define the utilities together Modeling is needed to make sure the existing facilities can be connected in a remaining way to benefit the growing communities and that technical the minimum amount of future storage is added constraints to reduce costs guiding a Joint Interconnection main sizing This study should be done in conjunction with Medium Utility distribution modeling and storage siting since they all affect each other Storage siting and utilization are both affected by the size of the interconnecting watermain Pressure zone analysis This study is needed to determine if pressure Low reducing valves or pump stations are needed to facilitate interconnecting the communities Well Siting Use of existing wells to benefit growing Medium communities is another key benefit to a joint utility This study would ensure that the supply is available to meet needs while not impacting surface water features of value.
