Charters Towers Regional Council has put out a reminder to any business operator or homeowner with a backflow prevention device on their land that the necessary testing involved is their responsibility.
The use of backflow prevention devices is to stop potentially polluted water reverse flowing into Council’s drinking water supply.
Council CEO Mark Crawley says property owners need to be aware of their responsibilities in this area.
“Under section 142(2) of the Local Government Act 2009, property owners with backflow prevention devices installed on their properties are required to have it tested annually by a licenced contractor,” Mr Crawley says.
“The licensed person who inspects or tests a testable backflow prevention device must give Council the written results of the inspection or test within 10 business days.
“Council has the power to require the owner or occupier of premises to install, register, inspect, test, repair or replace a backflow prevention device where it reasonably believes plumbing on the premises could pollute either the water supply in premises or the water service to premises.”
Mr says Council are legally required to sustain a registration, maintenance and testing of testable backflow prevention devices program.
Backflow occurs when a condition exists in a water supply system that will cause back-siphonage or back pressure.
This can happen on a property due to a vacuum being created in the water supply system.
Examples of back-siphonage are high withdrawal rates and pipelines either breaking or being undersized.
Back pressure occurs when pumps, thermal expansion or elevation create higher than normal pressure downstream.
Council have provided a list of establishments that could require a backflow prevention device.
These include motels, units, workshops, restaurants, medical centres, car washes, laundromats, hospitals, schools and sporting clubs.
Mr Crawley says to prevent backflow property owners need to locate and cut off the contamination source from the town water or their own water tanks at the tap or appliance.
Any property owner who fails to test appropriately within the correct time frame are in breach of the Local Government Act 2009.
