RJN Group Signs Contract with Buffalo Grove, Ill.

RJN Group Inc. recently signed a new contract with the Village of Buffalo Grove, Ill., to provide assistance with its MWRD compliance.

Buffalo Grove is located 35 miles northwest of Chicago with a population of 42,000 residents. The sanitary sewers are in the Cook County portion of the Village, and are tributary to the Metropolitan Water Reclamation District of Greater Chicago (MWRD).

In 2015/2016, RJN – a consulting engineering and specialty field services firm, — completed the initial MWRD submittal requirements for the Village.  This new contract is for professional engineering and specialty field services to help the Village meet short-term program requirements of the MWRD Infiltration/Inflow Control Program (IICP).

Among the services that RJN will provide for this particular contract are:

• closed-circuit televising (cctv) review of gravity sewers


• smoke testing


• manhole inspections


• dyed water flooding


• lift station inspections


• annual reporting

Using the data collected from these condition assessments of the MWRD prioritization area, the Village can develop a targeted, prioritized rehabilitation program to reduce inflow and infiltration entering the sanitary sewer system.

RJN will also be developing a private sector program (PSP) and a long-term operations and maintenance program (LTOMP) as required by the MWRD IICP. This program will bring Buffalo Grove into compliance with MWRD IICP requirements by the end of 2019.

RJN is in the process of completing similar MWRD compliance projects for other cities and villages in Illinois, including Des Plaines, Palatine, Rolling Meadows, Schaumburg and Wilmette.
