Lawn Sprinkling Restrictions

Lawn Sprinkler Valve Testing Required Annually

The State of Illinois requires that a back-flow prevention assemblies be installed on all hazardous cross-connections in an effort to keep our water supply safe. These assemblies must be tested and certified every year to ensure that they are working properly. The Village of Lemont has partnered with BSI Online to assist in administering the back-flow program in our community.

It is the residents responsibility to hire a licensed back-flow tester to perform the annual test and certification of the back-flow assembly(s). The test must be completed by a certified Cross Connection Control Device Inspector.  The Building Department maintains a list of certified testers. BSI does not test back-flow assemblies. Failure to submit the annual test report/certification may result in disconnection of the water service to your residence and/or issuance of citation.  All annual back-flow assembly test reports must be submitted electronically via the BSI Online system at by the testing company.  Please note there is a nominal filing fee per test report submitted. Each resident who owns a back-flow assembly (RPZ Valve) should be sent a notification letter from BSI with a Customer Confirmation Number (CCN). This number must be given to the tester in order for the reports to be properly filed with BSI. Please contact BSI via email at, by phone at 800-414-4990 or visit their website at should you have any questions.
Any residents wishing to permanently disconnect their lawn sprinkling system must contact the Village of Lemont Building Department at 630-257-1580.
