Returning home after a flood 

When returning home after floods it’s important to take precautions to reduce the possibility of illness, disease or injury. Here's what to consider.

Once the waters recede:

  • Cuts from broken glass and debris may be a problem – wear sturdy waterproof boots and rubber or leather gloves.

  • Don’t use any gas or electrical appliances before having them checked first.

  • Avoid any areas that remain flooded.

  • 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:

  • Damaged gas or electricity supplies – these hazards need to be declared safe by a qualified electrician or plumber.

  • The structural integrity of your home and structures may be affected – this needs to be declared safe by a qualified building surveyor.

  • 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.

  • In case gas has collected inside, do not smoke or use matches, lighters or other open flames. Use a torch or other battery-operated lights.

  • Pets and other animals may have died and need to be removed. For advice on safe disposal of animals, speak to your local council or veterinarian.

  • Mosquitoes can breed rapidly and become a nuisance – cover skin with long sleeves and pants and use an insect repellent.

  • Wild animals, including rodents, snakes or spiders, may be trapped in and around your home.

  • Flooding can cause excessive mould growth, which must be cleaned up before moving back to your home.

  • Flooding may cause sewage to overflow inside your home. Contaminated areas must be cleaned and disinfected. Keep children and pets away until the clean-up is completed.

  • If you rely on rainwater or groundwater, your water may be contaminated after floods. Find out what you need to know.

Returning home after a severe storm 

After a severe storm:

  • Check your home and property for damage.

  • Keep clear of damaged buildings, power lines and trees.

  • Be aware of road hazards such as floodwater, debris and damaged roads or bridges.

  • Do not drive through affected areas unless it is necessary.

Before going onto your property consider the following:

  • Gas or electricity supplies may be damaged – these may need to be confirmed safe by a qualified electrician.

  • The structural integrity of your home may be affected and weakened– this needs to be declared safe by a qualified building surveyor.

  • When cleaning up wear protective clothing (such as long pants and full sleeves) when returning home to your property. Make sure you also wear sturdy footwear and heavy-duty work gloves.  Wash your hands after removing contaminated clothing and articles.

  • Hazardous materials may include asbestos. Asbestos fibres can cause health problems if they are breathed in.

  • Contact your local council’s environmental health officer for enquiries or concerns regarding the safe removal or disposal of asbestos.

  • For information on asbestos visit the Better Health Channel website:

Floodwater and contaminated areas

Floodwater may contain sewage and therefore harmful microorganisms such as bacteria, viruses and protozoa, which can cause illnesses like gastroenteritis (gastro).

Flooding may cause an increase in sewer spills. If you notice a sewer spill avoid the area and open drains. To report a sewer issue call us 24/7 on 13 27 62

  • Do not swim or allow children to swim or play in floodwater. 
  • Avoid direct contact with sewage and any contaminated areas.
  • Keep children and pets away from sewage-affected areas until it has been cleaned up.

Pressure sewer impacts from power outages

During extended power outages - over 8 hours - customers may need to reduce their water usage to protect their pressure sewer system from overflow. 

  • Don't turn on clothes washing machines while the alarm is active.
  • Take shorter showers.
  • If a bath was filled, leave the plug in until after the alarm is cancelled OR empty out the water onto the lawn using a bucket. 
  • Switch off any drainage (automated or not) from swimming pools or spas until after the power is restored. 
  • Advise us of extended power outages, particularly if it exceeds eight hours (excluding time when the residents are asleep). 

Please continue to reduce water usage up to 12 hours after the power is restored.

Once power is restored, the pressure sewer pump will start pumping but it may take up to an hour for the wastewater level in the tank to drop below the alarm level. During this time the pressure sewer’s alarm may sound. If the alarm is still sounding after one hour please report a fault so a field crew can investigate further.  

Report a fault

Following extended power outage events, we may need to arrange to pump out your storage tank.

Find more detailed information about pressure sewers.

Impacts to septic tanks

This is general advice shared from Vic Emergency. For the latest information and advice:

Visit Vic Emergency website

  • Most septic tanks should not be structurally damaged by storms as they are below ground.
  • However, if you suspect your septic tank has been damaged, do not use or flush your toilet until you know that the septic tank system and associated pipes are intact.
  • If you suspect your system has been physically damaged, contact a licensed plumbing practitioner to have it assessed.
Untreated water customers

Some properties that are not serviced by our reticulation water network, access a water supply from a nearby Aqueduct or conduit.

After recent heavy rains and storm activity, a reminder to property owners who are supplied water from aqueducts or pipelines/conduits - this water is untreated and not suitable for drinking or food preparation as it may contain harmful bacteria or other organisms. This applies regardless of whether the supply is used as your main source of supply or as a second source of supply.

Temporary change in source of water supply Upper Yarra townships - updated 29/9/21

Due to the recent severe weather, customers who receive drinking water sourced from the Upper Yarra Reservoir, were temporarily supplied by water from the Silvan Reservoir.

Water quality has improved and in the coming weeks, these customers will start receiving safe and pleasant drinking water from Upper Yarra Reservoir once again.

While the water is of the same quality, a change in source can sometimes result in the water looking, smelling and tasting slightly different to what you are used to.


What happened in the Upper Yarra Reservoir?

The recent heavy rainfall and high winds have contributed to increased levels of turbidity in the water in the Upper Yarra Reservoir. To ensure you continue to have safe, high-quality drinking water during this time, we temporarily changed the source of your drinking water.

Where does the other water come from?

We supplied you with the same water that’s supplied to a large part of Melbourne’s eastern suburbs including the Monbulk area. This water supply has fluoride in it.

Will I notice a difference?

A change in the source of water supply can sometimes result in the water looking, smelling and tasting slightly different to what you are used to.

Adding or removing fluoride to the water supply will not affect the quality or taste of the water.

Which areas are impacted?

The following areas shaded on the maps below will return to its normal supply from the Upper Yarra Reservoir

My suburb isn’t serviced by Yarra Valley Water – is my water changing?

This temporary change in water supply only affects Yarra Valley Water customers. If you have any concerns, please contact your water retailer directly - South East Water on 13 28 12 or City West Water on 13 26 42.

Why are some areas impacted and not others?

The temporary change in water supply only affected customers whose water is supplied by the Upper Yarra Reservoir. The change in water supply started at different times for different customers as it depends on how close their property is to the Silvan Reservoir.

Why haven’t I received an email?

We are in the process of writing to affected customers. If your property is supplied by the Upper Yarra Reservoir, and you’ve registered your email address with us, you will receive an email. If we don’t have your email address, we will send you a letter in the mail.

Where can I get up to date information?

Please keep up-to-date on our website.

Is my usual drinking water supply fluoridated?

The drinking water supplied from your usual source, the Upper Yarra Reservoir, is not currently fluoridated.

Why do you add it?

Water fluoridation is the process of changing the amount of fluoride in drinking water to an optimal level to help reduce tooth decay. For Victoria, the fluoride content of drinking water is adjusted to an optimal level of approximately 1 mg/L (also known as one part per million).

Fluoride is added in accordance with the Health (Fluoridation) Act 1973 and the Department of Health’s Code of practice for fluoridation of drinking water supplies (second edition).

How much fluoride is in the water?

To help protect teeth against tooth decay, only a very small amount of fluoride is needed in drinking water. For Victoria, the fluoride content of drinking water is adjusted to an optimal level of approximately 1 mg/L (also known as one part per million).

For further information on water fluoridation see the Department of Health’s website:

View Department of Health's website

How do I know water fluoridation is safe?

Australia’s peak health body, the National Health and Medical Research Council (NHMRC), strongly recommends community water fluoridation as a safe, effective and ethical way to help reduce tooth decay across the population.

More information is available on the NHMRC’s website: View NHMRC's website 

How do we control the amount of fluoride supplied?

Fluoridation plants are designed to raise the natural fluoride concentration of the water supply up to the optimal concentration with very high precision. Continuous monitoring and automated fluoride dosing control at each treatment plant ensures that the level of fluoride in the water delivered to your tap is within the acceptable range.

Temporary change in source of water supply

Following the severe weather event in June this year, Melbourne Water stopped sending water from the Upper Yarra Reservoir to the Silvan Reservoir, which supplies water to the majority of our customers.

This change was needed as the turbidity in the water in the Upper Yarra Reservoir had increased. Turbidity is a measure of how clear the water looks.

As the turbidity has improved, Upper Yarra Reservoir will start being transferred back into Melbourne’s supply system via the Silvan Reservoir. This will mean we can meet the summer demand.

We are committed to providing you with the highest quality water and comply with regulations and law that outline standards for public health.

If you have any questions or require further information, please do not hesitate to contact us on 13 2762.
