Backflow Prevention Program 

City of Hamilton Backflow Prevention Program Update:

The City of Hamilton delivers safe and clean drinking water to all homes and businesses.  To further ensure that the system is protected on May 12, 2010 Hamilton City Council passed a new By-law referred to as the Backflow Prevention By-law #10-103.

The Backflow Prevention By-law will affect all industrial, commercial, institutional properties and multi-residential properties 4 stories or higher.

All property owners will be required to submit a Cross Connection Survey or Self Assessment Survey to determine the hazard level associated with their property.
All surveys are required to be completed and submitted to the City of Hamilton, 330 Wentworth Street North, no later than November 12, 2010.

Compliance dates for the installations of the backflow prevention devices will be based on the hazard level of your property, the hazard level is determined from the outcome of your survey.
If the hazard level of your property is high or severe your compliance date for the installation of your backflow prevention device will be no later than November 12, 2011.

For all other hazard levels your compliance date is May 12, 2012.
All backflow prevention devices will require an initial test upon installation and annually thereafter. 
The test results must be received by the City of Hamilton no later than
14 days after the test has been completed.

With the exception of the Self Assessment Survey all surveys, installation and testing to be done under the program must be carried out by a contractor that has been approved and is registered with the City under the program.  Please refer to the Approved Contractors List.

The City will be mailing out letters to all property owners affected by this By-law to invite them to attend public meetings.

Program:

The program focuses on the isolation of private water systems from the City's water distribution system by means of "PREMISE ISOLATION" which refers to the prevention of backflow or the reverse flow of water into the City's water distribution system from an owner's building, structure or property by the installation of a suitable Backflow Prevention Device located on the property owner's water service line at the entrance of such building, structure or property.
