Most of us don’t think much about the water coming out of our taps until something makes us notice — a funny taste, a strong smell of chlorine, or a friend mentioning they’ve switched to filtered water and haven’t looked back.
Perth has a pretty reliable and well-managed water supply, but ‘safe to drink’ and ‘great quality’ aren’t always the same thing. Here’s an honest look at what Perth tap water actually contains, and why so many families are choosing to filter it at home.
Where Does Perth’s Water Come From?
Perth’s drinking water comes from a few different sources depending on where you live: surface water from dams and reservoirs in the hills, groundwater pumped from underground aquifers, and desalinated water from plants at Kwinana and Binningup.
The Water Corporation treats all of this before it reaches your home, using processes that include filtration, disinfection, and pH adjustment. By the time it’s piped to your street, it meets Australian Drinking Water Guidelines.
But between the treatment plant and your tap, a lot can happen.
Chlorine: Necessary, But Not Always Welcome
Chlorine (and increasingly chloramine, a chlorine-ammonia compound) is used to keep the water supply free from bacteria during its journey through the pipe network. It does an important job, but it’s also one of the most common reasons people find Perth tap water unpleasant to drink or cook with.
If your water tastes a bit like a swimming pool, chlorine is likely why. Some people are also sensitive to it on their skin and scalp — particularly children or anyone with eczema or sensitive skin conditions.
Whole-home filtration systems are very effective at removing chlorine and chloramine, which is one of the main reasons they’re popular with Perth families.
Hard Water Minerals
As we mentioned in our piece on water softeners, Perth water tends to carry a reasonably high mineral load — particularly calcium and magnesium. This is what causes the limescale build-up you see on taps, showerheads, and inside appliances.
The minerals themselves aren’t harmful to health, but they’re hard on your home. Over time, they’ll reduce the lifespan of your hot water system, washing machine, and dishwasher — and they make cleaning a constant battle.
Sediment and Pipe Age
The water mains that supply Perth suburbs range from relatively new to genuinely old. Older pipes can introduce sediment, rust particles, or other debris into the water as it travels to your home. You might not see anything visible, but a sediment filter will often reveal just how much fine particulate matter was in the water you were drinking.
This is particularly noticeable when people install a whole-home filtration system and then look at the first filter cartridge after a few months. It can be quite eye-opening.
What About Bore Water?
For Perth homeowners on bore water, the quality considerations are quite different — and often more serious. Bore water isn’t treated before it reaches your home, which means whatever the aquifer contains, you get.
Common issues with Perth bore water include high iron content (which stains everything orange), elevated manganese, high mineral hardness, and sometimes bacteria. Many families use bore water for their gardens but wouldn’t consider it for drinking or bathing without proper treatment first.
Does Perth Water Need to Be Filtered?
Technically, no — you won’t get sick from drinking Perth tap water straight from the tap. But there’s a difference between water that meets the minimum safety standard and water that’s genuinely good.
Filtered water tends to taste better, which means families actually drink more of it. It’s gentler on skin and hair. It protects appliances. And it gives people peace of mind knowing that whatever might have made its way into the pipe network on the way to their home has been caught before it reaches the glass.
For a lot of Perth families, that’s more than enough reason.
