Understanding Perth’s Water: Where It Comes From & What’s In It

Most people in Perth don’t think twice about the water coming out of their taps — but understanding where it comes from can explain a lot about the taste, smell, and buildup you see around your home.

Perth’s water supply is actually a mix of different sources. These include groundwater (bore water), desalinated seawater, and rainfall collected in dams. Because of our dry climate, a large portion now comes from desalination plants, with groundwater also playing a major role.

While this keeps our water supply reliable, it also means the water is heavily treated before it reaches your home.

💧 What’s in Perth tap water?

To make water safe to drink, it’s treated with:

• Chlorine – used to disinfect and kill bacteria

• Minerals – naturally occurring, contributing to “hard water”

• Sediment – fine particles that can travel through pipes

This is why many Perth homeowners notice:

• A strong chlorine smell

• Dry skin and hair after showering

• White residue (limescale) on taps and appliances

🚿 Why it matters in your home

Over time, these elements don’t just affect taste — they can impact your entire home:

• Build-up inside pipes and appliances

• Reduced efficiency of hot water systems

• Increased wear on dishwashers and washing machines

✅ The solution

A whole home water filtration system treats water at the point it enters your home, meaning:

• Cleaner, better tasting water

• Reduced chlorine exposure

• Protection for your appliances and plumbing

It’s a simple way to improve the quality of water from every tap.
