Title
Substitute: Authorizing Madison Water Utility to use Water Well Solutions, LLC as a sole source provider of a Lamnaflo device and its installation in Unit Well 14, a water supply well.
Body
WHEREAS, Madison Water Utility completed an initial phase of a 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, 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 continued this investigation in 2023 by hiring a licensed municipal well driller to
rehabilitate the borehole both chemically and mechanically and then sample the well at lower aquifer depths
again but under “pumping” conditions, which required special down hole sampling equipment; and
WHEREAS, it was consequently determined that sodium and chloride levels at this well can be reduced
significantly by drawing more of its water from the lower aquifer and less from the upper aquifer utilizing a flow
control system in the well; and
WHEREAS, Water Well Solutions Wisconsin LLC is the only vendor that can provide and install the specific flow
control system (Lamnaflo) deemed necessary in increasing/decreasing flow at preferable levels within a well,
thus reducing the sodium and chloride levels in its Unit Well 14;
NOW, THEREFORE, BE IT RESOLVED, that the Common Council hereby authorizes Madison Water Utility the City to enter into a sole source agreement with Water Well Solutions Wisconsin, LLC as a sole source provider for a Lamnaflo flow control system and its installation in Unit Well 14, a water supply well, for 60 days, at a total price not to exceed $105,000, and authorizes the Mayor and City Clerk to sign a contract for the same.
