Backflow prevention

Council is implementing a backflow prevention device registration program across the Narrandera Shire.

How does backflow occur?

The water supply system is designed to ensure your property is supplied with potable water under pressure. Potable water that has been made safe to drink - drinking water. 

If there is a drop in the supply pressure, there is a risk that water could flow backwards into the water main. Water flowing back to the water mains could contain contaminates,  foreign matter, or debris. This usually occurs when there is cross-connection between potable and non-potable water sources. Contaminated water can then come out of the mains supply at another location, with the potential to harm.
