Changes in the quality of water sourced from rivers and creeks, bushfires, rain, or high demand for drinking water can all impact your drinking water supply.
While we do everything we can to plan and prepare for these circumstances, we want you to be prepared, too.

Water quality

All drinking water in the Coliban Water region is safe to consume.

Our experts follow strict regulations to make sure your drinking water meets all health-based Australian Drinking Water Guidelines and the criteria set out in the Safe Drinking Water Act 2003.

During hot weather our water treatment plants work hard to keep up with spikes in demand. Right now, they're also taking longer to treat your drinking water due to the poor quality of the water sourced from our rivers and creeks.

Some of our customers may be noticing changes to the look, taste, or odour of their drinking water.

We continue to closely monitor, test and revise our treatment processes throughout the day to suit local conditions. Look, taste and odour issues are likely to continue until the quality of the raw water sourced from rivers and creeks improves. This may take several weeks.

If you need assistance or have further questions, please call 1300 363 200.

Current towns affected by poor raw water quality

Last updated: Monday 26 February 2024

EchucaYour water is safe to drink.

You may continue to notice a temporary change to the look, taste, or odour of your drinking water due to increased levels of geosmin in the town's raw water supply. While elevated levels of geosmin do not create any health risks, it can create a distinct odour, even if present in very tiny amounts. More on geosmin here.

Our plant continues to treat and manage levels of geosmin. From Tuesday 27 February, water trailers located at Wilkinson Drive and High Street will be removed as a result of water quality stabilising.


We will continue to closely monitor Echuca's water quality.

CohunaYour water is safe to drink.

While your water supply is returning to normal, the Cohuna Water Treatment Plant continues to work hard to treat the poor-quality raw water being sourced from Gunbower Creek.

We thank you for your cooperation over recent weeks. We no longer require you to limit non-essential water use, however, please continue to observe the five Permanent Water Saving Rules.

Dingee and MysiaWe are experiencing poor raw water quality due to increased levels of blue-green algae in the raw water supply at both Dingee and Mysia.

We have increased our water quality testing program to monitor the situation more closely.

Customers in these towns are reminded that your water supply is untreated and not suitable for drinking, food preparation, tooth brushing or ice-making. We recommend access to an alternative source of water.

It is also recommended that pets are not given this water to drink.


Your water and health as temperatures rise

When temperatures outside heat up, demand for water also increases. People use more water to run air conditioners, water their garden and keep cool.

While most of the region will be unaffected, customers in some areas may experience variable or low water pressure.

You can help by considering how you can minimise your water use:

Try to avoid watering your garden between 6pm and 10pm.

Be waterwise and keep showers short.

Wash only full loads of clothes.

Skip the car washing while it’s hot.

Stay up to date with Bureau of Meteorology Heat health warnings.

  • In hot weather, keep cool, avoid vigorous physical activity and, most importantly, drink water to stay hydrated.
  • Check on elderly neighbours and family members to ensure they are okay during hot weather.
  • Note heat-related messages from the Department of Health and Emergency Management Victoria
  • Please reconsider all non-essential water use during peak-times on hot days.
