FROM: David E. Schumacher, P.E.; Superintendent of Water Production

SUBJECT:
A Resolution Authorizing Well Maintenance Services for Well No. 129 for the Water Production Division.
PURPOSE:
To obtain City Council authorization for Layne Christensen Company (Layne), 721 W. Illinois Avenue, Aurora, IL, to perform all necessary services as described in Layne's proposal letter (attached) to return Well No. 129 to full operational and functional status.
BACKGROUND:
Well No. 129, located at 1374 Deerpath Road, is a shallow well with the pump and motor setting at 125 feet below the surface and is normally capable of supplying approximately 1,000,000 gallons of water per day. The well was placed into service in 2011 when it was newly constructed. The well has operated effectively and efficiently since that time with no mechanical failures or need for service. However, currently the well is only producing approximately 60% of its rated capacity which is likely attributed to mechanical wear or possibly column piping that has failed. It is advisable at this time, and recommended by Layne, that the pumping equipment be removed from the well, inspected, and repaired to restore normal pumping capacity.
Layne has been authorized via a not-to-exceed purchase order of $14,000.00 to complete typical Phase I work to include removal of the pump, motor, and column piping; disassembly of pump components for cleaning and inspection; complete a field mechanical/electrical inspection of the Flowserve-Byron Jackson motor; and perform a televised inspection of the well borehole.

The total estimated project cost of all proposed work to restore Well No. 129 to normal operational status is $54,500.00. A detailed breakdown of the estimated costs is presented in Layne's proposal letter.
The city entered into a Professional Services Agreement (PSA) with Layne in 2020 under Resolution No. R20-083, which provides a...
