DATE: October 21, 2016
SUBJECT:
A Resolution Authorizing Repairs to Normal Pressure Pump #3 at the City of Aurora Water Treatment Plant 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 and repairs to return Normal Pressure Pump #3 (NPP#3) to full operational and functional status.
BACKGROUND:
NPP#3 is one of six finished water pumps that supply water from the water treatment plant to the normal pressure zone of the water distribution system. Approximately 70% of water provided to the city is supplied to the normal pressure zone. Each of these six pumps is individually capable of pumping from 3000 - 4000 gallons per minute. Recently, treatment plant staff noted unusual noises (rattling) coming from this pump. This is typically a sign of impending mechanical failure. NPP#3 had last been removed for repair work in June, 2007.
Under a not-to-exceed purchase order of $25,000.00, Layne was hired to remove the pump, inspect all pump components, and provide a proposal of needed repairs and associated costs. To date, Layne has invoiced for services of approximately $10,000.
DISCUSSION:
The total estimated cost of all proposed and recently completed work by Layne to restore NPP#3 to full operational status is $49,522.00.
A detailed breakdown of the needed repairs and associated estimated costs has been provided by Layne and is attached in a separate proposal letter.
The city entered into a Professional Services Agreement (PSA) with Layne in 2012 under Resolution No. R12-290, 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 utilized by the Water Production Division.
Funds are available in the 2016 City Budget in Account No. 510-4058-511-38-01.
IMPACT STATEMENT:
Not completing the necessary repairs will reduce the treatment plant's ability to pump finished water to customers.
RECOMMENDATIONS:
That a resolution authorizing repairs to Normal Pressure Pump #3 by Layne Christensen Company per the existing PSA in an amount not to exceed $53,000.00 be approved by the Mayor and City Council. It is further recommended that this matter be submitted to the Buildings, Grounds, and Infrastructure Committee for review and recommendation.
