About KRMA


The Kankakee River Metropolitan Agency is located on 89 acres of land adjacent to the Kankakee River. In 1996, the Kankakee River Metropolitan Agency (KRMA) was formed. KRMA owns and manages the facility through a Board of Directors. The original facility was constructed in 1930 and upgraded and expanded in the 1960ís, 1970ís and 1980ís as well as the most recent in 2006.


Plant Design/Utilization Data:

Design Flow Capacity 25 MGD    

Current Average Flow 12.5 MGD

Design BOD 40,000 lbs/day    

Current loading 20,000 lbs/day


Service Area:

KRMA has an approved facility planning area (FPA) which represents approximately two-thirds of the County of Kankakee.  This FPA includes the City of Kankakee and Villages of Aroma Park, Bourbonnais and Bradley.  Major interceptors owned by the municipalities serve the existing population and radiate to the north, east, and south of the metropolitan area.


NPDES Effluent Limitations:

BOD (Biochemical Oxygen Demand 20 mg/l

SS (Suspended Solids) 25 mg/l     


Customers Served:

It is estimated that there are 57,500 persons served within the City and the three Villages, 30 significant industrial dischargers and approximately 700 commercial users.


Currently KRMA is utilizing two forms of alternative energy production. The first form of alternative energy production is the Kankakee City Hydroelectric Plant.  This plant contains three induction 400 kWh generators.  Due to the stipulations from IDOC (Illinois Department of Conservation) and FERC (Federal Energy Regulatory Commission) the operator needs to maintain 500 CFS (Cubic Foot / Second) over the dam at all times.  Anything above and beyond the 500 CFS can be utilized through the turbines for energy production. The available river flow, therefore, determines the amount of power the hydroelectric plant can produce for use by KRMA.  During the summer months low flow conditions often restrict the operation/production of the Hydro Electric Plant.  During the winter ice can be a factor that may restrict the inlets and reduce the potential production.  Flood conditions also reduce production by reducing the available head difference between the upstream and downstream elevations.  In most cases there is not enough flow for all three hydroelectric units to produce power at the same time.  Normally, two units are available and average production can range from 280 kWh to 620 kWh. 


The second form of alternative energy production available is the methane fueled engine/generators located at KRMA.  There are two syncronous 240 kWh Waukasha engine/generators.  One by product of anaerobic digestion of sewage sludge is methane gas. Water is separated from the gas and the methane is supplied from the digesters to the engine/generators.  At this time, there is insufficient gas production for two engine/generators to operate continuously. The operation of one engine/generator can produce from 160 kWh to 200 kWh under normal operating conditions. The engine/generators can also produce power from natural gas.


The switchgear at the KRMA is supplied by two Commonwealth Edison feeders.  These two feeders are supplied from the substation located on Armour Road just to the west of the Canadian National Railroad tracks in Bourbonnais.  The feeders from Commonwealth Edison, the Hydroelectric Plant and the engine/generators are connected directly into the KRMA switchgear located west of the main entrance.
