# Why Does Perth’s Water Supply Require Filtering?

Perth is fortunate to have a reliable public water supply, but that does not necessarily mean the water arriving at your home is free from substances that affect taste, odour, appearance or the condition of your plumbing.

Many Perth homeowners choose to install a whole-house water filtration system to improve the quality of water throughout their property. Filtration can help reduce chlorine, sediment and other unwanted substances, providing cleaner, better-tasting water from more of the taps in your home.

Perth’s Water Supply Comes From Multiple Sources

Perth’s drinking water is supplied from a combination of sources, including:

● Groundwater

● Surface water from dams

● Desalinated seawater

● Groundwater replenishment

These sources are treated before entering the public water network. However, the characteristics of the water can vary depending on its source, location and the condition of the local supply infrastructure.

Water can also travel through extensive pipe networks before reaching your property. During this journey, it may pick up sediment or develop a noticeable chlorine taste and odour.

Why Is Chlorine Added to Perth’s Water?

Chlorine is commonly used to disinfect drinking water and help protect it from harmful microorganisms as it travels through the distribution network.

This is an important part of maintaining a safe public water supply.

However, some people dislike the taste or smell of chlorine in their drinking water. Chlorine can also be noticeable when showering, bathing or washing clothes.

A suitable water filtration system can help reduce chlorine and improve the taste and odour of water throughout your home.

Sediment Can Enter the Water Supply

Sediment may include fine particles such as sand, rust or other material from plumbing and water infrastructure.

Although water is treated before distribution, sediment can sometimes enter the supply through:

● Ageing or disturbed water mains

● Local plumbing work

● Repairs and maintenance

● Construction activity

● Older household pipework

● Water tanks and internal plumbing components

Sediment may appear as cloudiness, discolouration or visible particles in the water. It can also accumulate in tap aerators, shower heads, washing machines and other water-using fixtures.

A whole-house sediment filter can help capture these particles before they travel through your home’s plumbing.

Perth Water Can Affect Taste and Odour

Even when water meets drinking-water standards, it may not taste or smell the way you prefer.

Common complaints include:

● Chlorine taste

● Chlorine odour

● Metallic or earthy flavours

● Stale-tasting water

● Unpleasant shower odours

Activated carbon filtration is commonly used to reduce chlorine and improve the taste and odour of drinking water.

The correct filter media and system design depend on the substances present in the water and the goals of the homeowner.

Filtering Water Throughout the Home

A small under-sink filter can improve the water from one tap, but it does not treat water used elsewhere in the property.

A whole-house water filtration system is installed on the incoming water supply so filtered water can be delivered to multiple outlets, including:

● Kitchen taps

● Bathroom taps

● Showers

● Baths

● Laundry taps

● Washing machines

● Outdoor fixtures, depending on the installation

Whole-house filtration can be particularly useful for homeowners who want to reduce chlorine exposure during showers and improve water quality throughout the property.

Filtration and Water Softening Are Different

Water filtration and water softening solve different problems.

A water filter may be designed to reduce:

● Chlorine

● Sediment

● Taste and odour compounds

● Selected contaminants, depending on the filtration technology

A water softener is designed to reduce hardness minerals, primarily calcium and magnesium. These minerals can contribute to scale on shower screens, taps, tiles and appliances.

If your main concern is chlorine taste or sediment, filtration may be appropriate.

If your main concern is white scale and mineral deposits, you may need a water softener.

Some Perth homes benefit from a combination of whole-house filtration and water softening.

Does Every Perth Home Need a Water Filter?

Not every property requires the same type of water treatment system.

The most suitable solution depends on:

● Your local water source

● Water quality concerns

● Existing plumbing

● Household water usage

● Desired flow rate

● Available installation space

● Whether you want drinking-water filtration or whole-house treatment

● Whether hardness and scale are also a concern

A professional assessment can help identify the right system rather than relying on a one-size-fits-all filter.

Benefits of Whole-House Water Filtration

A correctly selected and installed whole-house filtration system may help to:

● Improve the taste of drinking water

● Reduce chlorine odour

● Capture sediment and particles

● Protect tap aerators and shower heads from debris

● Provide filtered water at multiple outlets

● Improve the showering experience

● Reduce reliance on bottled water

● Support better water quality throughout the home

The results depend on the filtration technology, filter capacity, water conditions and ongoing maintenance.

Why Professional Installation Matters

Whole-house filtration is connected to the main water supply, so installation should be completed carefully.

A professional installer can assess:

● Water pressure

● Pipe size

● Flow requirements

● Filter capacity

● Drainage and bypass requirements

● Available space

● Future cartridge replacement

● Compatibility with existing plumbing

Correct sizing is important. A filter that is too small may restrict flow or require frequent replacement, while an unsuitable system may not address the water-quality issue you are experiencing.

Frequently Asked Questions

Is Perth tap water safe to drink?

Perth’s public drinking water is treated and regulated. However, some homeowners still choose filtration to improve taste, odour and the overall experience of using water in their home.

Does a water filter remove chlorine?

Many activated carbon filters are designed to reduce chlorine. The result depends on the filter media, system design, flow rate and maintenance.

Will a water filter remove hard-water scale?

A standard water filter does not necessarily remove calcium and magnesium hardness minerals. A water softener is generally used to reduce hardness and scale.

Is an under-sink filter enough?

An under-sink filter treats water at one outlet, usually the kitchen tap. A whole-house system treats water entering the property and can supply filtered water to multiple outlets.

How often do water filters need servicing?

Replacement intervals depend on the filter type, water quality, household usage and manufacturer’s recommendations. Regular maintenance is essential for reliable performance.

Can filtration and softening be installed together?

Yes. Filtration and softening can be combined when a property needs both chlorine or sediment reduction and treatment for hard-water scale.
