Fiscal Note
The proposed resolution requests amendment of the 2022 Water Utility Capital Budget to transfer $100,000 from Account Number 13594-86-150 (Project Name: 2022 Unit Well Rehab Program) to Account Number 11900-86-140 (Project Name: UW 14 Mitigation) for engineering services necessary to conduct a groundwater/borehole characterization study at Unit Well 14 (Alder District 19).
Project costs will be funded through the existing Utility Construction Fund balance and/or Utility cash reserves. No increase in Utility debt obligations or new borrowing will be required for these projects.
The 2022 Water Utility adopted Capital Budget will be amended to reflect the following:
1) ($100,000) from 13594-86-150 - 2022 Unit Well Rehab Program
2) $100,000 to 11900-86-140 - Unit Well 14 Mitigation
Title
Amendment of the 2022 Water Utility Capital Budget to authorize the transfer of funds from the 2022 Unit Well Rehab Program to the Unit Well 14 Mitigation project. (Alder District 19).
Body
WHEREAS, Madison Water Utility completed the initial phase of the water quality/borehole characterization study at Unit Well 14 which determined that the well draws the majority of its water from the shallower, upper aquifer compared to the deeper, lower aquifer, resulting in elevated sodium and chloride levels; and
WHEREAS, earlier in 2022 the Utility, working with SCS Engineers, under non-pumping conditions, completed additional water sampling within the borehole at depths representing the deeper, lower aquifer, which upon testing, demonstrated that the lower aquifer water had lower concentrations of sodium and chloride; and
WHEREAS, the Utility wishes to continue this investigation by sampling the well at lower aquifer depths again but under “pumping” conditions, which will require removal of the well pump which will remove the well from service for approximately 30 to 40 days; and
WHEREAS, in order to complete this study, a licensed municipal well driller will need t...
