TO: Mayor Richard C. Irvin
FROM: David E. Schumacher, P.E.; Superintendent of Water Production
DATE: January 30, 2020
SUBJECT:
A resolution authorizing well maintenance services for Well No. 28 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. 28 to full operational and functional status.
BACKGROUND:
Well No. 28, located at 1960 E. Indian Trail, is a deep well with the pump and motor setting at 1006 feet below the surface and is normally capable of supplying approximately 1,890,000 gallons of water per day. Well No. 28 was first placed into service in July, 2008 and until recently has operated without any mechanical or maintenance issues. As with all wells, the gallons per minute or flow produced has tapered off over time. However, in November of 2019, the Water Production Division staff observed a significant decline in flow of approximately 30%. This is normally indicative of an equipment or mechanical failure. Past experience with other wells suggests that a hole may have developed in the column piping, preventing all of the pumped water from reaching the surface.
Subsequently, under a not-to-exceed purchase order of $25,000.00, Layne recently completed the removal of the pumping equipment and confirmed that indeed a hole exists in the pump's column pipe. In addition, as a result of water jetting through the hole, the submersible power cable was also damaged. Numerous other repairs and basic maintenance work are normally recommended and performed given the opportunity of having the equipment removed from the well and at the surface.
DISCUSSION:
The total estimated cost of all proposed and recently completed work by Layne to restore Well No. 28 to operational status is $207,649.00. 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 2012 under Resolution No. R-12-290, which provides a 5% discount on all labor and field services, and a 10% discount on specialized services performed by Layne. Layne will perform all work on a time and material basis and will only be compensated for the actual work performed per the terms and conditions of the PSA. In addition, Layne is the sole regional factory authorized source for repair services of Flowserve-Byron Jackson pumps and motors utilized by the Water Production Division.
Funding is available in the 2020 City Budget in Account No. 510-4058-511-38-31 in the amount of $310,000.00 for Water Well Repairs and Maintenance Services.
IMPACT STATEMENT:
Inability to pump approximately 1,890,000 gallons per day of raw well water for treatment and supply of finished water to the city if the maintenance work is not completed.
RECOMMENDATIONS:
That a resolution authorizing well maintenance services for Well No. 28 by Layne per the existing PSA in an amount not to exceed $215,000.00 be approved by the Mayor and City Council. It is further recommended that this matter be submitted to the Finance Committee for review and recommendation.
