What's Actually in Your Tap Water?

Most people don’t think much about their tap water until something makes them notice it.

Maybe it’s a chlorine taste in your drinking water. White residue building up around your taps. Dry skin or hair after showering. Glassware that never seems to come out completely clear.

It often raises the same question: “What’s actually in my tap water?”

Australian drinking water is treated to strict safety standards and is generally considered safe to drink.

However, by the time it reaches your home, it can still contain a variety of naturally occurring minerals and treatment additives, including:

  • Calcium and magnesium, which contribute to water hardness
  • Chlorine, used to disinfect and treat the water supply
  • Fluoride, added in many areas to support dental health
  • Naturally occurring dissolved minerals and salts
  • Sediment or rust from ageing household pipework or recent water main repairs


These are all relatively common, generally safe to consume and don’t automatically indicate there’s anything wrong with your water.

Why Does Tap Water Taste Different?

One of the most common questions we hear is why tap water seems to taste different from one suburb to another, or even from one house to the next.

Several factors can influence the taste, smell and appearance of your water, including the local water source, treatment process, household plumbing, and even the age of the pipes supplying your property.

It’s also why visitors often notice their drinking water tastes different when they’re away from home.

It’s Not Always About Drinking Water

For many homeowners, the biggest difference isn’t what comes out of the kitchen tap.

It’s what they notice throughout the rest of the house.

Hard water minerals can leave residue on shower screens, taps and appliances. Chlorine can affect the smell and taste of water, while sediment may sometimes appear after water main repairs or maintenance works.

Some homeowners also find their skin and hair feel drier after showering, particularly in areas where mineral content is naturally higher.

Is Water Filtration Worth It?

Whether a water filtration system is worthwhile really depends on what you’re hoping to improve.

Some homeowners simply want better-tasting drinking water.

Others are looking to reduce chlorine, minimise sediment, improve water quality throughout the home or help protect fixtures and appliances from the effects of hard water.

The right solution will vary from property to property, which is why choosing the right filtration system is just as important as choosing to install one in the first place.

Choosing the Right Water Filter

Not every home needs a whole-house filtration system.

For some families, an under-sink drinking water filter provides everything they’re looking for. Others prefer whole-home filtration to improve water quality at every tap, while properties using rainwater tanks may benefit from UV filtration to help treat collected water before it’s used throughout the home.

The best system depends on your water source, household needs and budget.
