Returning to your home after a flood
When returning to your home after a flood, take precautions to reduce the possibility of illness, disease or injury. Before going onto your property, consider:
Personal hygiene is essential during floods
A number of infectious diseases, including gastrointestinal infections and hepatitis A, can spread through contact with contaminated surfaces. The likelihood of illness increases when floodwater contains faecal material (poo) from overflowing sewage systems, agricultural or industrial wastes. Never use contaminated water to wash dishes, brush your teeth, wash your hands, wash and prepare food, make ice or make baby formula. Always wash your hands with soap and safe water (that has been boiled or disinfected):
If boiled or disinfected water is not available, you can use alcohol-based products to disinfect your hands. If you have any open cut or sore that has been exposed to floodwater:
Parents need to help their children avoid waterborne illness. Tips include:
Food supplies may be contaminated
Floodwaters can affect food through direct contact or, indirectly, by causing interruptions to power supplies, affecting local refrigeration. Throw away:
For cleaning cans that are still sealed, not bulging and intact, but have come into contact with floodwater:
If the power is on, refreeze or cook food that has thawed but contains ice crystals and is below 4 °C. If the power is off, store food safely by:
Preventing illness from contaminated water
Local water authorities will tell you if tap water is safe or unsafe to drink, use for cooking, cleaning or bathing. If the water is not safe, use bottled, boiled or disinfected water. An above ground rainwater tank that has not been inundated with floodwaters or damaged should be safe for continued use. Correctly boil water by:
Correctly disinfect water for drinking by:
For infants:
Clean children’s toys that have come into contact with floodwater by:
Managing sewage overflow inside your home
Sewage contains harmful bacteria and viruses. Keep children and pets away from sewage affected areas until it has been cleaned up. Appropriate clean up procedures include:
Septic tanks and floods
If you live in a flood-affected area and flood waters have affected your property, your septic tank system (also called an onsite wastewater system) may also be affected.
Wastewater from your home contains sewage from your toilet and grey water from your bathroom, kitchen and laundry. Wastewater contains human disease-causing microorganisms such as bacteria, viruses and parasites. Diseases can be transmitted to humans from wastewater if appropriate measures are not taken. The safe disposal of wastewater is therefore essential to protect your health and the health of others. Ensure children and pets are kept away from wastewater affected areas.
Septic tank systems typically comprise a concrete, plastic or fibreglass tank which collects the wastewater from toilets, the bathroom, kitchen and laundry in the home. In a functioning system, the solids in the wastewater settle in a primary tank, the wastewater is then discharged through pipes into soil in a designated area on your property.
Your septic tank system must be operated and maintained in accordance with the septic tank permit issued by your local Council and the Certificate of Approval issued by EPA Victoria.
Most septic tanks should not be structurally damaged by flooding as they are below ground. However, flood water may enter your septic tank system through the toilet, other fixtures or the overflow relief gully grate. Flooding of the septic system may wash out solids from the tank causing blockages or system damage.
Failed systems are not easy to identify; however, some simple indications may include:
Some onsite wastewater treatment systems may rely on mechanical and electrical equipment such as pumps, aerators and filters. This equipment may be damaged by flood or loss of power. To prevent injury or further damage to your system contact your service agent.
What should I do if I suspect my septic tank has been affected?
Do not use or flush your toilet until you know that the septic tank system and associated pipes are intact, otherwise wastewater could flow back up into the house through the toilet, shower, bath, and laundry drains.
If you suspect your wastewater system has been physically damaged by the flood, contact a licensed plumbing practitioner to have it assessed.
Septic tanks inundated with flood water, silt and debris should be professionally cleaned as soon as possible after the flood water has subsided. It may be necessary to pump out tanks, wells or distribution pits and slotted pipes if they are clogged with displaced solids. Refer to your local business directory to arrange a septic tank pumping service by a licensed contractor.
Cleaning or pumping out a flooded septic tank should be done with care as this could cause the tank to float out of the ground and damage the structure and pipes. After a septic tank is pumped out, it should be filled with water to prevent it from floating out of the ground.
If the disposal area is waterlogged or clogged, additional water will not be absorbed into this area and will pool on the surface. Remedial measures such as pumping out the whole septic tank system may be necessary. This may need to be done several times. Saturated soil is especially susceptible to compaction, which can lead to system failure. Avoid compaction of the soil over the wastewater disposal area caused by driving or operating equipment in the area. In extreme cases the disposal area may need to be re-installed. A licensed plumbing practitioner should assess the disposal area for this potential requirement.
For worm farm septic tank systems, composting toilets or other EPA approved systems, contact the manufacturer for specific advice on how flooding or power outages may affect these systems.
In most situations turning off power to pumps may be necessary to prevent flooded pumps from overheating, wearing out or pumping out untreated water. In some instances, the pump may be required to be left on to prevent other types of damage – contact your service agent for advice.
What should I do if sewage has overflowed inside my home?
Sewage contains harmful bacteria, viruses and parasites. Sewage needs to be cleaned up as soon as possible. Keep children and pets away from the area until this is done. Some appropriate clean up procedures are:
For further advice, contact your local water authority or the Environmental Health section of your local council.
Onsite wastewater system:
Buloke's Environmental Health Officer can provide advice on remedial works, your existing permit or installation of a new system.
Plumbers:
Refer to your local business telephone directory for licensed service providers.
Contact your medical doctor regarding any health conditions that may have resulted from contaminated water supplies.

Cleaning up after a flood
When cleaning up after a flood, wear protective clothing, such as sturdy footwear, loose long-sleeved shirts and trousers and heavy duty work gloves. There may be asbestos debris in your home. Where there is extensive demolition, repair and renovation work involving asbestos-containing material, licensed asbestos contractors should be employed to undertake the work. Flood recovery suggestions include:

Japanese encephalitis (JE) virus update 11/11/2022
There have been no confirmed cases of JE and no detections of JE virus in mosquitoes so far this season. JE virus is only one of several infections transmitted by mosquitoes.
The simplest and best way to prevent JE virus infection and other mosquito-borne diseases is to avoid mosquito bites.
Advise people of the importance of regular and routine mosquito bite prevention to help prevent JE and other mosquito-borne diseases.
Refer to Protect yourself from mosquito-borne disease - Better Health Channel <https://www.betterhealth.vic.gov.au/campaigns/protect-yourself-mosquito-borne-disease>
Global supply of JE vaccine is limited. For eligibility criteria refer to: Japanese encephalitis - Vaccination <https://www.health.vic.gov.au/infectious-diseases/japanese-encephalitis-virus>
For emergency management workers deployed for prolonged flood recovery efforts from other regions, vaccination can be administered after arrival in flood affected areas.
