METROPOLITAN WATER RECLAMATION DISTRICT OF GREATER CHICAGO
2009 BUDGET
• $130,000 to rebuild two existing centrifuge gear boxes, which are currently past their useful service lives and require
original equipment manufacturer (OEM) rebuild services. The existing gear boxes can be rebuilt by the OEM to the
original specifications;
• $120,000 to rehabilitate pump rotating assemblies. We currently do not have any spare rotating assemblies for our main
sewage pumps. This contract will allow us to have enough spares available for our four main sewage pumps, until the new
pumping station is on line. The purpose for the partial rehabilitation of the smaller rotating assembly is to have spares
available for our return sludge pumps, along with the smaller pumps at 95th Street Pumping Station;
• $120,000 to upgrade the waste gas flare system at the digesters. The existing system/controls are obsolete and need to be
upgraded. The upgrade will allow us to install a new Foxboro control system for this equipment that will be compatible
with the existing plant wide process control system.
The largest impact on our 2009 budget request is an additional $877,500 for the anticipated increased cost of electricity, due to
renegotiation of our rates in 2009, and $350,000 for natural gas, for a total utility increase of $1,227,500. We are working with
the Energy Conservation committee to identify, minimize and reduce our energy unit consumption, with a goal of reducing
consumption up to 5 percent District wide by 2013. Reduced consumption is not anticipated to reduce associated dollars due to
the high volatility of electricity and natural gas costs seen in recent years.
THE CALUMET MASTER PLAN
The Calumet Master Plan, developed jointly by the M&O and Engineering departments, has projected plant process needs
through the year 2040. Major construction projects recommended and in process are:
• Hydraulic Improvements (High Level Influent Pumping Station), Contract 93-232-2M. This new pumping station
construction is in progress and our expectation is that this contract will be completed in 2010;
• Central Boiler Facility, Contract 03-296-3M. To meet demands for process and building heating and cooling is currently
under construction. This contract is tentatively scheduled for completion in 2009;
• Two additional 75,000 standard cubic feet per minute Blowers, Contract 06-218-2M. To provide all process and auxiliary
air needs from the existing Blower Building and eliminate the existing blowers located in the Pump and Blower Building,
soon to be replaced by the new Pumping Station. We anticipate this contract to be awarded in 2009;
• Preliminary Treatment Facilities (grit facilities and primary settling tanks), Contract 07-220-3P. This will provide new
updated and appropriately sized grit removal facilities and new primary settling tanks with primary sludge and scum
systems. The existing aerated grit, preliminary settling tanks, primary sludge concentration tanks, and primary pumping
system will be removed from service. This contract was awarded in 2008;
• Pre-Digestion Sludge Thickening Facilities, Contract 96-251-2P. This is a modification and upgrade to the facilities for
better process and control. Anticipated construction period is to be 2009.
ENGINEERING DEPARTMENT PROJECTS
The following projects are currently on-going Engineering contracts, not part of the Master Plan.
• 00-275-2V, Research and Development Facility. This provides for a state of the art lab facility;
• 04-294-3M, Calumet TARP Valve Isolation and Pump Station Upgrade. This replaces four (4) of the larger existing
pumps, installation of emergency dewatering systems, and replacement of switchgear;
• 00-809-1E, Installation of Remote Monitors for Unmanned Sites. This provides for equipment to remotely monitor for
intrusion, smoke/fire, loss of power, etc. at the various pump stations, reservoirs, SEPA stations, and gate chambers
located throughout the District.
ENGINEERING PROGRAM PROJECTS BEGINNING CONSTRUCTION IN 2009 INCLUDE:
• 06-212-3M, E1 and W1 Pump Modifications. This contract provides for the replacement of the existing 28.8 million
gallons per day (MGD) pumps with larger 72 MGD pumps controlled by variable frequency drives;
• 98-260-2M, Coarse Screen Replacement, Piping, and Electrical work at 95 th Street and 125 th Street Pumping Stations. This
contract provides for the replacement of the old bar screens, along with the installation of a conveyor system for the
collection and disposal of debris that has been collected by the coarse bar screens. There will also be some replacement of
suction and discharge piping at the 125 th Street Pump Station.
