Backflow Prevention

All water supply systems intended for human consumption, food preparation, utensil washing or oral hygiene must be safeguarded from contact with contaminated water. This applies to water services connected to rainwater tanks, main water supply and/or alternative water supplies. A water supply should not be offensive in appearance, taste or odour.

Backflow prevention is the term used to prevent the reverse flow of water from a potentially polluted or contaminated source into drinking and bathing water supply systems. By installing a backflow prevention device this risk can be managed. There are a number of backflow prevention devices available to suit any particular situation.

Backflow Prevention Devices

A backflow prevention device prevents the reverse flow of potentially contaminated water into the reticulated water supply system.

Examples of potential source of contamination are but not limited to:

  • Fire Hose Reels (FHR)
  • Irrigation
  • Swimming pools
  • Ornamental ponds
  • Vehicle maintenance pits
  • Air conditioning towers
  • Vehicle/bin washing bays
  • Chemical injection areas
