Backflow Prevention Program
Our customers have relied on us to produce and deliver excellent water that meets or exceeds all quality standards for more than 140 years.
To protect the public water supply, Department of Public Utilities policies require precautions to be taken to isolate any contamination or pollution that may be present in consumer water systems which could backflow into the public water supply. “Backflow” is the reverse flow from the fixture/equipment back into the drinking water pipeline. There are two types of backflow:
- Backpressure – This occurs when water pressure generated from a private service exceeds the water pressure provided by the City’s water system. Causes for increased pressures from a private system may include a pump, elevated tank, boiler, or other condition.
- Backsiphonage – This occurs when backflow is caused by negative or reduced pressure in the water supply piping.
Cross-connections are the links between the public drinking water supply and auxiliary water such as a pond, holding tank or well. Backflows into the public water supply can be prevented with the installation and maintenance of Backflow Prevention devices.
A licensed Backflow Prevention contractor is required to install and test Backflow Prevention assemblies.
The City of Toledo is proud of the water we deliver to your door each day. We thank you for your cooperation in preventing backflow by maintaining cross-connection protections.
Since 2015 the City of Toledo has worked with Backflow Solutions, Inc., or BSI Online, to collect and manage data related to cross-connection controls to protect the water supply.
Attention Backflow Testers
All commercial customers are required to submit annual backflow prevention assembly tests and maintenance reports through the BSI Online tracking system. BSI can be reached by phone at 800-414-4990. (See BSI Contractor Registration document for more information)
Paper backflow test reports will no longer be accepted directly by the City of Toledo.
ANNUAL BACKFLOW PREVENTION ASSEMBLY TEST AND MAINTENANCE REPORTS MUST BE SUBMITTED DIRECTLY TO BSI ONLINE. A $20.95 fee is applied for each test report submitted.
Backflow Prevention questions may be directed to Shawn Clark, with the City of Toledo Division of Water Distribution, at 419-936-2681.
