Frequently asked questions
Why am I getting water from the Yan Yean Reservoir now?
Melbourne Water and Yarra Valley Water have worked together to increase the water supply by using Yan Yean Reservoir. This provides more water into the water supply system for a growing population across 32 of Melbourne’s northern suburbs.
Is it safe to drink?
Yes, the water is safe to drink. The Yan Yean Reservoir is a major supply system that can supply residents and businesses with high quality drinking water.
The source of your water may be different but the water is treated to the same drinking water quality standards as your previous water supply.
Why does my water appear different?
A change in water source can sometimes mean your water looks, smells or tastes slightly different. This is because it comes from a different place. It is still safe to drink and use as normal.
Will the water smell more like chlorine?
No. We add chlorine to water as part of the water treatment process. The chlorination levels are within the same range as other sources of water in the Melbourne area.
Will running taps or boiling water help with changes in smell, taste or appearance?
No, you may notice a slight change but boiling the water won’t change the way it tastes. Your water supply is treated to the same drinking water quality standards as all water in our service area.
Why is my water a different colour? Is it safe to bath or shower?
Water can look slightly different depending on where it comes from. Your water is clean and safe. Any change in colour is not from dirt or your water pipes.
You can use your water normally for things like drinking, showering, bathing and washing dishes or clothes.
Why haven't I heard about this change?
At times we need to change where we supply water from. This is something we manage on behalf of our customers to ensure there is enough water to supply everyone we need to.
We have provided information through targeted social media posts to people living and working in the suburbs that receive the new supply. As well as our faults map, and website.
Why am I getting a different water supply but a neighbour is not?
Different areas around Melbourne will be serviced by different water tanks. The location of these different service areas can mean neighbours living across the street get their water from different places. Close neighbours can be affected differently when we have a change or a disruption to water supply.
Yan Yean Reservoir has been used before and I didn’t like the taste. What’s different now?
The water from Yan Yean Reservoir is treated with new treatment processes. All of the water we supply passes stringent water quality standards so we can supply safe and pleasant tasting drinking water.
