City of Ramsey, Minnesota REQUEST FOR PROPOSALS Analyze Source Water, Develop Water Model, and Prepare Preliminary Design Report for Centralized Water Treatment Facility August 8, 2019 Scope of Services The City of Ramsey is requesting proposals from qualified consultants for providing the following professional services. 1. Analyze Source Water. Analyze and report on the overall accessibility, capacity, chemistry and limitations of the Tunnel City/Wonewoc (TCW) aquifer, the existing source water for the City of Ramsey's municipal groundwater supply system, and on the long-term viability of continuing to use the TCW aquifer as the sole source of water for the municipal water supply system. This will allow the selected consultant to adequately prepare a preliminary design report by understanding the chemistry of the municipal groundwater supply system and therefore which primary, secondary and/or emerging contaminants will need to be treated over the anticipated life of the facility. This work will also allow the selected consultant to provide recommendations on the need for and use of alternative sources of water. 2. Develop Water Model. Develop a model of the City of Ramsey's municipal water supply system using an industry standard software program. This model will allow the selected consultant to adequately prepare a preliminary design report, and will allow the City to evaluate future operations throughout the system by considering variable flow regimes when water is drawn from different wells and storage tanks at different times, variable water usage patterns by municipal water consumers, and proposed system expansions. 3. Prepare Preliminary Design Report. Prepare a preliminary designreport exploring available options and recommending preferred processes for treating known and emerging contaminants that will potentially need to be treated over the anticipated life of a centralized water treatment facility in the City of Ramsey. The report must examine available treatment process options for identified contaminants potentially needing treatment, recommend a preferred treatment process for each identified contaminant, identify required space needs for preferred treatment processes, identify anticipated expansion needs, provide a recommendation as to the required size and preferred location for the facility, and provide cost estimates for constructing and operating the facility over its anticipated life.
