Water supply management following fire

Please note: This content may be out of date and is currently under review.

Protecting your most vital water supply from contamination should be your first priority after a fire. Material such as ash and soil, from burnt paddocks and bushland, can be blown or washed into farm dams as nutrients for bacteria and algae. 


Keep an eye on water supplies and remove stock or treat water if polluted. Dams may require emergency chlorination of water, or treatment for toxic algae blooms.

If erosion becomes a long-term problem, it is advisable to have a design of appropriate surface water management structures prepared by a consultant. This design can then be incorporated into an existing or new internal fencing plan. 

Sediment traps/windbreaks

Constructing a windbreak to drop the sand behind it will help prevent sand getting into buildings, yards and dams. This deposited sand can be carted away or another barrier constructed.

The windbreak can be as simple as a section of fence with brush woven into it, coarse shade cloth attached, or straw, and should be in place as soon as possible to be prepared before the next rain. Commercial windbreak material like Paraweb can be used but at a greater expense.

More information is available from the Victorian Department of Primary Industries factsheet, Building a sediment fence.

Being prepared for fire

It is essential that landholders are proactive about preparing for the threat of fire.

Having a plan to follow will help avoid last minute decisions. The more you prepare your property, the better the chance it will have of surviving a fire.
