Project Update

Beginning October 24 the contractor will begin disconnecting individual water services from the old water main and connect the water service to the new water main.  To complete this work we will need to shut your water off for at least  two (2) hours.  At this time a specific date has not been set for each individual service connection.  You will be notified at least one day in advance of the work being performed and once again the morning of the work.  Please review the following notice for additional information.



The Village of Mount Prospect will be replacing existing watermain along Elm Street between Central Road and Thayer Street.  A recent study of the Village’s watermain system identified that this section of watermain pipes are old and undersized.  This 1,300’ long section of watermain has had numerous breaks and is in need of upsizing to provide the desired capacity.  The smaller 6” diameter pipe will be replaced with larger 8” diameter pipe.  This will improve the water flow and minimize the service interruptions due to watermain breaks.  A contract has been awarded to Patnick Construction, Inc. of Franklin Park.  It is expected that construction activities will start the week of September 11th.  The new watermain will be installed under the parkway on the west side of Elm Street.  To minimize the disruption, the watermain pipe will be installed by directional boring.  Pits will be dug at both ends of the blocks along with one at each midblock and the pipe will be pushed underground from the pits.  Following completion of the watermain installation, the house services will be reconnected to houses on both sides of the street.  The watermain construction should be completed by the end of October.

Type of Work to be Performed

In general, the process of installing the new watermain will include:

  • Excavation of bore pits.
  • Installation of new watermain by directional bore.
  • Testing and chlorination of new watermain.
  • Transfer of water services to new watermain.
  • Sidewalk, curb and pavement replacement as necessary.
  • Restoration with topsoil and sod of any parkway areas damaged during the construction activities.
Will My Water Service be Affected
There will be no extended disruption in your water service. However, there will be a short disruption (typically less than 20 minutes) when your water service will be transferred to the new watermain. You will be notified prior to your service transfer.
Will Services to My Property be Affected

Due to the location of the work, there will be no changes in your regular services such as garbage pick-up, mail delivery, or emergency services from the Police and Fire Departments.  There may be times during the day when construction activities temporarily block access to your driveway as the new watermain is being installed.  We will try to make these interruptions as short as possible.  If new curb or sidewalk is to be installed in front of your property, access to your driveway will be interrupted for a more extended period.  In that case, you will receive more specific information about the schedule for this work and how it affects your driveway access within the next few weeks.  During that time the Police Department will be instructed to relax the restrictions on overnight street parking at these locations while driveways are not accessible.  If you have special needs due to a disability, please contact the Public Works Department.  Please use caution when driving through the construction zone.
