Water, electricity and gas
Water is crucial to the survival of people and buildings during a bushfire
Bushfire is likely to disrupt the mains water and electricity supply. Consider using alternative systems or ensure that you have a back up. Gas is less critical to survival but it can present additional hazards that need to be managed.
See Water, electricity and gas (under New builds) for advice on retrofitting utilities. Most of the advice will apply to both new and existing buildings.
