March 17, 2023 -- A ComEd transformer failure earlier today sent a power surge into the Village of Oak Park's Central Pumping Station. This power surge triggered one of the pumps in the station to ramp up to 100 percent power, approximately 10 percent higher than normal.
This increase in power caused by the surge resulted in an approximate 15 percent increase in pressure within the Village's distribution system. Increases in pressure can cause water main breaks where the system may be weakened by age or deterioration.
The Village is currently experiencing two water main breaks: on the 900 block of N. Oak Park Avenue and the 400 block of S. Lombard Avenue. Oak Park Public Works staff is responding to these situations and a contractor has been called in to assist. In order to allow crews the space necessary to complete repair work, as of 8 a.m. Friday, Oak Park Ave. is closed between Division St. and Berkshire St.; Lomard Ave. is closed between Madison St. and Washington Blvd. Service interruptions are likely in the vicinity of these two breaks.
Overall, distribution system pressure and the Village's water quality has not been impacted at this time. Additional breaks resulting from this surge may occur through the weekend and into next week.
Residents can contact the Public Works Department at 708.358.5700 or firstname.lastname@example.org with questions or to report issues related to their water service.
