RE:                                          RFB 1109 Chiller Replacement - De-Cal, Inc.




Upon recommendation of Suzanne Coffey, Chief Planning Officer, Interim Chief Operating Officer   - Wastewater, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA) authorizes the Chief Executive Officer (CEO) to enter into an Agreement for Chiller Replacement with De-Cal, Inc. at a cost not to exceed $1,049,240.00 and authorizes the Chief Executive Officer to take such other action as may be necessary to accomplish the intent of this vote. 




This is a replacement needed for an outdated, poorly operating current chiller that is not adequately providing air conditioning for the New Administration Building at the Water Resource Recovery Facility.  The chiller system was installed in 1995 and its operation has been deteriorating over the last five years.  The current chiller runs on gas, which causes the gas bills to be high during the winter and summer months.  The scope of improvements include replacement of the 300-ton gas fired absorption chiller/heater with two modular 255-ton electric chillers and two high-efficiency gas fired 1,500 MBH heating hot water boilers.  In addition, six pumps serving the heating systems and chilled water systems will also be replaced.  A plate and frame heat exchanger will be required to isolate the new chillers from the existing cooling tower system.

Project Estimate

The project was estimated to cost $1,000,000.00. The expected start date is April 1, 2018.


The chiller replacement is budgeted for FY 2018 as HVAC replacement in the Improvement and Extension Capital Outlay over $5,000 account for the Wastewater Operations (892221) cost center.  The table below represents the financial plan for this project.

Capital Outlay - Wastewater Operations

FY 2018

 FY 2018 Amended


$ 1,000,000.00



The forecast of this was $1,000,000.00.  The remaining $49,240.00 will be a budget amendment from the unallocated reserve in the Improvement & Extension Fund.  This will only be necessary if the full 10% contingency is utilized.


Lower utility costs are expected, however, the savings has not yet been determined.



This item was presented to the Operations and Resources Committee at its March 14, 2018 meeting.  The Operations and Resources Committee unanimously recommended that the GLWA Board adopt the resolution as presented.


This item does not impact the shared services agreement between GLWA and DWSD.
