How Does Melbourne's Tap Water Compare

How Does Melbourne Tap Water Compare?

Have you ever thought that your Melbourne tap water tastes funny? Or perhaps it’s been looking a little cloudy. You might even be wondering if it is safe to drink tap water in Melbourne or are you safer sticking to bottled water?

Metropolitan Plumbing is your expert plumber in Melbourne. So, we’re going to run you through everything you need to know about Melbourne’s drinking water so you can keep yourself and your family safe.

Is Melbourne Tap Water Safe to Drink?

Yes – Melbourne tap water is absolutely safe to drink. In fact, it’s among the best tap water in the world and even got second place in ‘best municipal water’ category at the International Water Tasting Competition for both 2016 and 2019!

This competition pitted water from across the world against each other to find the world’s best water. Ten judges sampled tap water and determined the winners based on several factors:

  • taste
  • appearance
  • aroma
  • mouthfeel
  • aftertaste

More than just safe to drink, Melbourne water is some of the highest quality in the world. Move over bottled water, Melbourne water is a two-time winner of the International Water Tasting Competition!

What is in Melbourne’s Tap Water?

Melbourne is one of only two cities in the world that sources its water from protected catchments. Up in the Yarra Ranges, native forests act as a natural filter, meaning we only need to disinfect Melbourne water.

Sponge-like soil in these ranges holds rainwater which is slowly released into water reservoirs. These water catchments also have very limited public access, so little treatment is required to clean it.

Water is kept in these reservoirs for up to five years which is plenty of time for any impurities present to break down.

Water from natural reservoirs still undergoes treatment to ensure it meets strict drinking water quality guidelines. Protected catchments are disinfected in at least one of three ways:

  • Small amounts of chlorine added
  • UV irradiation treatment
  • Membrane filtrations

Fluoride is also added to protect our teeth and keep them strong. Post-treatment, Melbourne tap water is perfectly safe to drink!

How is Melbourne Tap Water Quality Tested?

Melbourne’s tap water goes through rigorous testing before it reaches our taps. Public health is always the top concern for Melbourne’s water supply authorities.

Melbourne’s water supply is tested for a number of factors to ensure its high quality:

  • mineral content
  • pH
  • chlorine and fluoride concentrations
  • bacteria
  • contaminants such as pesticides and fuel
  • water hardness
  • radiological quality

Every year, Melbourne water authorities test samples from over 160 sites to ensure the quality of our tap water.  Over 3,000 microbiological and 800 physical/chemical samples are collected and tested annually.

Aesthetic components of our tap water are also tested:

  • colour
  • smell
  • clarity
  • mouth-feel

Melbourne’s water supply authorities are dedicated to maintaining our exceptional water quality.
