Buildings in flood hazard areas
For new buildings or additions to be constructed in a flood hazard area, you will need to install a reflux valve.
This valve will stop discharge from the sewer or onsite treatment plant potentially contaminating the building during a flood event.
The reflux valve is required to be fitted between the building and:
- if the building has an onsite sewerage facility—the on-site sewerage facility; or
- otherwise—the sewer connection point.
Can I install and maintain the valve myself?
No, it must be done by a licenced plumber or drainer.
