Emergencies with your GVW services

If you have a critical issue or emergency, we’re available 24/7 via our Customer Service Centre in Shepparton.

If you have a non-emergency issue, please report a fault here.

Water quality


The raw water within the Broken Creek continues to be of a very poor nature as a result of the floods. We are primarily focussed on ensuring the water meets all health targets but we continue to optimise the treatment plant to remove as much of the material causing the discolouration as possible.

We understand and acknowledge that the water will at times appear discoloured, for example within a bath -  we are sorry for this and we are continuing to optimise the treatment plant to limit this from happening. Importantly the colour is aesthetic only and meets all health requirements. We're seeing raw water quality continue to improve during the past week. 

Flood water carrying debris into and along the Broken Creek can cause a chemical reaction that leads to low dissolved oxygen levels and high levels of minerals in the water, such as manganese. Even small amounts of manganese can cause discolouration in the water and will be noticeable against a white back drop – shower and handbasins, white linen etc.

Washing machines: if you are experiencing discoloured water then we recommend you use a Napisan, Sard Wonder or similar product. We are working with the local supermarket to increase supplies locally, however if you are experiencing issues either with your water supply or obtaining appropriate products please let us know.

If discoloured water stains your laundry, soak it in water straight away. The staining caused by discoloured water is due to particles lodged in the fabric. The stain is likely to become permanent only if the laundry is allowed to dry. You can also request a cleaning powder kit or use a non-chlorine based powder to help remove staining.

Teams continue to flush the water main system to improve areas where we are experiencing discolouration. We'll continue to monitor the area closely over coming days until water quality improves. 

We have also undertaken extensive sampling of the raw water upstream of the treatment plant. This will provide us with an indication of what water is heading our way. We will analyse this and continue to change our response accordingly.

You can report any issues to our 24/7 Customer Service Team by calling 1800 454 500. We'll keep you updated here and via text message.


The recent flooding has lead to a large volume of organic material (leaves, grass, soil, other natural debris) entering the Goulburn River. The river is the source water supply for treatment for Barmah residents. There is a chance that treated water could be discoloured by the high amount of organics in this source water. Some customers may detect this colour change in baths and the bases of showers.

If you notice water discolouration please contact 1800 454 500.

Drinking water supplied to your home is safe to drink. Water is fully treated and meets all quality regulations.

When floods wash leaves, grass and other organic material off riverbanks and floodplains into waterways this may result in what may be called a blackwater event. The affected water appears darker, often similar to the colour of black tea. High levels of organic matter in waterways, combined with warm weather, can cause oxygen levels in the water to drop, making it harder to treat for drinking.

Our water quality team is monitoring the raw water quality in the rivers and creeks as a result of flooding, and where needed we’re adapting our treatment processes to still supply high quality water.

We will keep you updated on the situation.

Drinking water supplied to your home is safe to drink. Water is fully treated and meets all quality regulations. There are no boil water notices in place for any towns supplied by us.

Our water quality team is monitoring the raw water quality in the rivers as a result of flooding, and where needed we’re adapting our treatment processes to still supply high quality water (i.e. removing all the additional dirt and sediments in the raw water).

If you are in an area which may be impacted by flooding, we recommend you store 20 to 40 litres of water in containers for drinking in preparation for if an emergency does occur.

Sewer services

Where areas are flooded or have experienced inundation due to heavy rainfall, the sewer infrastructure may be experiencing higher than normal loads and additional pressure.

You may notice your toilet refilling slower or drains running slower – this is normal during these events. The system will return to normal in time.

In a flooding event, we advise customers to check their overflow relief gullies are not blocked. This is a small drain located outside your house, which is designed to release any overflow outside and away from your house.

The flooding or stormwater may lift lids of sewer manholes or may bubble up through. The water is stormwater but we advise people to avoid the immediate area as a precaution. If you see a sewer manhole spilling, please let us know by reporting it through our form.

If you have a critical blockage or immediate emergency, please contact us on 1800 454 500.

Stormwater/drainage is the responsibility of local councils – please check with your council for more information.

Preparing and protecting

We’re working hard to protect our facilities and infrastructure and monitoring key sites 24/7 to keep providing services to customers.

Our Incident Management Team is meeting several times a day to respond to any issues and monitor situations across flood-path-impacted areas.

We’re have operations and maintenance response units on both sides of the causeway so we can continue to respond to issues and faults in the system. Critical assets have all been protected in each flood zone.

If you’re waiting for us to respond to an issue you have raised, please be patient – our teams may need to prioritise responses with other issues, including immediate flooding responses or critical supply issues. We’ll be with you as soon as possible – thanks for your understanding.


The Shepparton Water Treatment Plant (which also supplies Kialla, Congupna, Tallygaroopna, Toolamba and Mooroopna) continues to operate and water is safe to drink – there’s been no impact to the water treatment assets on site. Staff are continually monitoring the plant, including adapting the water treatment process where needed due to poorer raw water quality resulting from the floods.

The majority of sewer pump stations are back online – a few in low-lying areas near the river are still being assessed. Some residents may notice their drains running slow – this will improve as the high volumes in the sewer network reduce.

We’re continuing controlled temporary wastewater discharges from the Shepparton Wastewater Management Facility – we still have staff onsite running the plant although access is more limited.


We are continuing to supply safe drinking water to residents.


The bulk of flood water has receded and today we’ve been able to access the two remaining offline sewer pump station near Lenne St in Mooroopna. Our team has worked to get them back online successfully on Wednesday afternoon, and services have been reinstated for all customers affected by the offline pumps (south of McLennan St and west of Toolamba Rd). Your wastewater service should have returned to normal, but please contact us on 1800 454 500 if you experience any issues.

We’ve now moved all the pumping equipment off the roads, and will continue to support efforts to remove flood waters across Shepparton and Mooroopna – we’ll mobilise our main large pump at other locations across the next couple of days.

You can resume normal water use. 

The ADF helping us to move our pumps and pipework out of Lenne St today.


There’s been a lot of progress in our work to pump flood waters out of Lenne St to assist Council, despite the rain this afternoon. We’ll continue pumping as long as required to remove the bulk of the water in the area.

We’re optimistic that tomorrow we’ll be able to start working to put a bypass system in place to reinstate the remainder of the sewer service in the area – we’ll also be working to repair any damaged pumps or infrastructure as needed. We thank all residents for their understanding and the way you've engaged with GVW during this time – we know this is having an impact.

We’ll have further updates tomorrow, but we ask people to still reduce the volume of wastewater produced where possible (i.e. take short showers, hold off running dishwashers/washing machines). 

Pumps onsite on Tuesday.


We have five large pumps in place (images below) to support Greater Shepparton City Council to pump out water from around Lenne St, with an additional pump put in place on Monday. It’s estimated that these are pumping out about 60ML/day (equivalent to 60,000,000 litres). Traffic control will be in place while pumping is occurring.

Two pump stations remain offline as they’re still flooded, but we have worked to get a subsection of the sewer network operational today, which is closest to McLennan St. This will help improve the service for residents in that area, and as we can access the two remaining pump stations, we’ll work to put in a solution to reinstate services for the remainder of the affected area (south of McLennan St and east of Toolamba Rd).

Work to clear a surcharging manhole on Lenne St is complete – we ask if people do see water coming from sewer manholes to report it to us on 1800 454 500.

We are asking residents in the affected areas to reduce the volume of wastewater entering the sewer network from their properties (i.e. showers, washing machines, dishwashers). You may notice your toilets and drains aren’t running as normal, or draining slowly - this will improve as the volume of water in the system decreases. 

We know this is having an impact on many residents who are facing significant challenges at the moment. We’re really sorry. We’re doing everything we can to get the affected parts of the sewer network online as soon as possible – we’ll keep providing updates on this page. 

If you’re in an area that is affected by offline pump stations – and because the system has been partially offline for a while – there are some temporary portaloos available if your toilet system stops working, or as an alternate option if you need it.

Portaloos available:

  • Corner Hall St and Toolamba Rd
  • Charles St opposite the playground
  • Other locations to be added as needed.

Treated wastewater has been released from the Mooroopna Wastewater Management Facility, all under control now.

Other lagoon wastewater treatment systems not directly impacted by floodwaters.


Water supply remains unaffected in Seymour and is safe to drink. Flooding has impacted one sewer pump station - once its safe to do so, we will dispatch crews to repair. Customers may notice slow drains or their toilet flushing slowly – this will return to normal in time once the immediate pressure on the network has reduced.


We’ve sandbagged critical assets at the water treatment plant and put measures in place to protect and staff will monitor the water supply ahead of the flood peak arriving.


The raw water pump has been repaired and treated drinking water is now being supplied by the Nagambie Water Treatment Plant - it's safe to drink. Tankering from Seymour has now stopped.

One sewer pump station remains offline - once waters recede and its safe to do so, we'll send a team out to assess it. 

Other towns

Where it’s safe to do so, we’re checking water treatment plants and monitoring our infrastructure. There’s no impact to supplies to customers in towns not listed above.
