Water Division

One of the most important jobs of the Public Works Department is to ensure that the residents of Tinley Park have a safe, dependable water supply. For this reason, the Water and Sewer Division works to ensure that our sanitary sewer system and water system are up-to-date and functioning properly at all times.

For more information, contact Interim Water Superintendent Jeff Cossidente at (708) 444-5500 or jcossidente@tinleypark.org, or Water Foreman Joe Fitzpatrick at (708) 444-5535 or jfitzpatrick@tinleypark.org.

Backflow Preventer Use Survey
The Illinois Environmental Protection Agency (IEPA) requires every water supply to develop and implement a cross connection (backflow prevention) control program. A requirement of the program is to send a survey to all residential water customers every two years. Visit the Village website for more information on water backflow assembly.

RPZ Inspections
RPZ (reduced pressure principle backflow preventer assembly) devices are required to be installed on all lawn sprinkler systems per Illinois Plumbing code. The Illinois Environmental Protection Agency (IEPA) and the Illinois Plumbing Code require all RPZ devices to be inspected and tested annually, regardless of use, by a certified inspector. A copy of the certification from an inspector must be submitted to the Village every year. If you no longer need your irrigation system, please read the irrigation removal document for information on how you may start the process to remove your irrigation system.
