CC Regular Session Meeting Date: 5. 16. 07/25/2023 Primary Strategic Plan Initiative: Address infrastructure needs. Information Title Adopt Resolution #23-168 Approving Professional Services Agreement to Revise Plans and Re -Bid Improvement Project #21-08, Water Treatment Plant Trunk Watermain Improvements Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #23-168 Approving a new Professional Services Agreement to Revise Plans and Re -Bid Improvement Project #21-08, Water Treatment Plant Trunk Watermain Improvements. Background: The City of Ramsey utilizes groundwater from the Tunnel City-Wonewoc (TCW) aquifer, formerly known as the Franconia -Ironton -Galesville (FIG) aquifer, as its exclusive source of drinking water. The City owns and operates eight municipal water supply wells, with seven available to supply water to the City's municipal water users. Water test results from the municipal wells show that concentrations of manganese range from 0.02 mg/L to 0.37 mg/L. The Minnesota Department of Health (MDH) recently established Health Based Values (HBV) for manganese of 0.100 mg/L for bottle-fed infants, and 0.300 mg/L for everyone else. Four of Ramsey's eight water supply wells exceed the MDH HBV for manganese. In early 2019, MDH recommended that the City develop short and long-term plans to reduce manganese concentrations in our water supply system. In April 2019, the City instituted it's short-term plan by employing only the three wells with the lowest manganese concentrations to supply water to municipal water users to reduce manganese concentrations throughout the water supply system as much as practical. The City also began working towards its long-term solution to construct a water treatment plant to remove manganese from the municipal water supply system. On October 8, 2019, the City Council adopted Resolution #19-248 awarding a contract to SEH Inc. to complete a Feasibility Study for a water treatment plant. On March 9. 2021, the City Council adopted Resolution #21-061 ordering plans and specifications for Improvement Project #21-08, Water Treatment Plant Trunk Watermain Improvements. On May 25, 2021, the City Council adopted Resolution #21-143 approving the Water Treatment Plant Feasibility Study prepared by SEH, Inc. On October 26, 2021, the City Council adopted Resolution #21-303 approving plans and specifications and authorizing advertisements for bids for Improvement Project #21-08, Water Treatment Plant Trunk Watermain Improvements. On January 25, 2022, the City Council adopted Resolution #22-033 rejecting bids for the Water Treatment Plant Trunk Watermain Improvements, Improvement Project #21-08, and authorizing Staff to work with SEH, Inc. to revise the approved plans to reduce project costs and to monitor the bidding environment to identify the most favorable time to bid the project again.
