The Village of Oak Lawn Water Division has contracted M.E. Simpson to perform necessary and preventative maintenance of the distribution system to ensure proper operation.

Accumulated sediment in the water main and fire hydrants will be flushed during normal business hours

Monday through Friday from 7:00 a.m. until 3:00 p.m.

Beginning September 25th through September 26th 2017

While flushing is underway short temporary periods of low pressure and discolored water can be expected, but DOES NOT present a health hazard.

To restore clarity to your tap water use a faucet with the aerator removed, or use a laundry sink faucet without an aerator, and flow the cold water until it clears.

M.E. Simpson will give notification by placing signs in the parkways of the areas they are working in. Questions call Water Department 708-499-7747

                     Locations of system maintenance are:

                     95th Street to 99th Street, Nashville to Harlem.

                     Please refrain from doing Laundry during these times if Possible


Any questions regarding this Flush Program may be directed to the Water Division at 708-499-7747.

Oak Lawn is dedicated to maintaining and improving its infrastructure to meet the needs of current residents and to be prepared for future generations.  From 2007 through 2013 the Village undertook an aggressive infrastructure improvement program to repair and replace a substantial portion of its infrastructure.  This is just a first step in a multi year annual maintenance program.  Like many Chicagoland communities built in the "post war" era, Oak Lawn will need to replace its aging infrastructure in the coming years.  To view the progress and history of recent improvement projects click here

The Village supplements local funding for these improvements with a combination of Motor Fuel Tax, Surface Transportation Program Funds, ARRA Stimulus funds and low interest Build America Bonds.  Oak Lawn continues to seek additional funding through local, state and federal agencies to get the most out of local dollars spent on these projects.   Oak Lawn works closely with the Illinois Department of Transportation (IDOT), the Metropolitan Water Reclamation District (MWRD) and the Cook County Highway Department (CCHD).  These agencies own and maintain infrastructure within Oak Lawn boundaries that serves Oak Lawn residents.
