DONATIONS: Donations towards townships affected by the fires can be made via Givit.
Backflow occurs because a condition exists in a water supply system that will cause back-siphonage or back-pressure. Back-siphonage can occur on a property through a vacuum created in the water supply system.
An example of back-siphonage would be a pipeline breakage, undersized pipework or high withdrawal rates. Back-pressure can occur within properties when high pressure is generated downstream by pumps, thermal expansion or elevation.
Examples of potential source of contamination:
- Fire Hose Reels (FHR)
- Swimming pools
- Vehicle maintenance pits
- Ornamental ponds
- Air conditioning towers
- Vehicle/bin washing bays
- Chemical injection areas
Examples of properties requiring backflow prevention:
- Motels and unit complexes
- Vehicle repair workshops
- Caravan parks
- Medical and dental surgeries
- Car and plant washing facilities
- Dry cleaners and laundries
- Hospitals and funeral parlours
- Club houses for sports
- Day care centres and kindergartens
- Pest control and water carrying vehicles
- Botanic gardens
Safeguard to prevent a backflow occurrence
A correctly selected backflow prevention device (one-way valve) will eliminate any risk of contamination of the drinking water supply. Backflow devices are either testable or non-testable types with the selection dependent on the risk associated with the possible contamination.
