SUBJECT:
Resolution to authorize a Professional Services Agreement for the design and construction observation of the Main Pump Station Improvements for the Water Production Division.
PURPOSE:
To obtain City Council approval to attain a professional engineering services agreement with Crawford, Murphy & Tilly, Inc., Aurora, IL (CMT) for the design and construction observation of the Main Pump Station Improvements for the Water Production Division.
BACKGROUND:
The Main Pump Station (MPS) was constructed in 1935. For many years, the MPS was the central supply for the City's Water Works System. When the Water Treatment Plant (WTP) was constructed in 1991, the MPS was no longer used for normal operating conditions. Currently, the MPS is maintained in a "standby" mode, but its full existing pumping capacity is required for the WTP to be able to reach its rated capacity. The facility also provides operational flexibility for the Water Production Division.
DISCUSSION:
The Main Pump Station needs to be maintained in a fully operational condition for a number of reasons. If there is a loss of service event on one of the city's large transmission mains, the MPS would be needed to supply finished water to the downtown and southeast areas of the city. Use of the existing pumping capacity at the MPS during periods of high demand (summer) is necessary for the WTP to reach its rated capacity. Also, for the past two summers, the MPS has been utilized to assist with the water main flushing program on the west side of the City.
Some of the main components to be improved as part of the project are 1) Replacement of the Motor Control Center and other electrical equipment which are no longer code compliant; 2) Masonry tuck-pointing of the exterior of the brick building; 3) Installation of a permanent ammonia dosing system, rep...
