What Are the 5 Common Contaminants in Unfiltered Brisbane Water?
Brisbane and South East Queensland tap water is treated and monitored, but many homeowners still want to reduce the things that can affect taste, smell, shower comfort, plumbing, appliances and everyday water quality once water travels through the network and into the home.
The five biggest water concerns Brisbane homeowners ask us about are disinfectant taste and smell, disinfection by-products, sediment and pipe particles, hardness minerals and scale, plus emerging trace contaminants such as PFAS.
Most homeowners do not start with contaminants. They start with how the water feels.
Your water might be treated, but it can still taste chemical, smell stronger in the shower, leave residue, or carry sediment from the network and household plumbing.
Common signs Brisbane homeowners notice
- Chlorine or chemical smell from taps and showers
- Water that affects the taste of tea, coffee and cooking
- Dry-feeling skin or hair after showering
- Scale or residue around taps, glass and fixtures
- Cloudy, discoloured or gritty water after pipeworks
- Concerns about older plumbing and what is travelling through the home
This is where Complete Home Filtration is different. Instead of treating water at only one outlet, a whole home system is installed before water reaches the key areas of your property.
Is Brisbane tap water treated?
Yes. Brisbane and South East Queensland water is treated and monitored before it is supplied to homes. Public water treatment is important because it helps protect water as it travels through dams, treatment plants, mains infrastructure and local pipe networks.
But treated water and filtered water are not the same thing.
Treated water is designed to meet public health requirements across a large supply network. A home filtration system is designed to improve the water experience inside your own property — including taste, smell, sediment reduction, shower comfort and broader household water use.
That is why many Brisbane homeowners are now looking beyond basic tap filters and exploring complete home filtration systems that filter the water they actually live in every day.

5 common contaminants and water quality concerns in unfiltered Brisbane water
This is not about fear. It is about understanding what can affect the water you drink, shower in, cook with, clean with and run through your home every day.
Chlorine and chloramine disinfectants
Disinfectants such as chlorine and chloramine are used in treated water systems to help control microorganisms and maintain water quality through the network. The issue for many homeowners is the remaining taste, smell or chemical feel once that water reaches the home.
You may notice a chlorine-like smell from showers, a chemical taste in drinking water, or water that affects tea, coffee and cooking. A single tap filter may help at one outlet, but it does not address the water used in bathrooms, laundry or showers.
Disinfection by-products
Disinfection by-products can form when disinfectants interact with natural organic matter in source water. Common examples include trihalomethanes, often called THMs, and haloacetic acids, often called HAAs.
Disinfection is essential for public water safety. The more practical question for homeowners is whether they want to reduce residual disinfectants and associated by-products at the point where water enters the property.
Sediment, rust and pipe particles
Even treated water can pick up particles as it travels through mains infrastructure, local pipe networks and household plumbing. Sediment may also appear after water main works, plumbing repairs, pressure changes or disturbances in the network.
Homeowners may notice cloudy water, grit in tap aerators, staining around fixtures, or dirty pre-filters during replacement. Sediment is one of the most visible reasons homeowners choose a whole home water filtration system.
Hardness minerals, scale and residue
Water hardness and dissolved minerals can contribute to scale, residue and build-up around household fixtures and appliances. In Brisbane and SEQ homes, this may show up as white marks on shower glass, build-up around taps, reduced soap lather or residue in kettles and appliances.
Jila Water systems can include a water conditioning stage designed to support better water feel and reduce scale-related issues throughout the home. This is especially useful for homeowners who want more than just drinking water filtration.
PFAS and emerging trace contaminants
PFAS are often called “forever chemicals” because they are persistent in the environment. They have been used in a wide range of industrial and consumer products and are now part of broader public discussion around water quality in Australia.
Unlike chlorine taste, sediment or scale, PFAS cannot be seen, tasted or smelt. That is why homeowners concerned about PFAS and other emerging contaminants need to look carefully at system design, filtration media, flow rate and testing context.
Why whole home filtration is different from tap, fridge or shower filters
A small filter can help one outlet. A complete home filtration system is designed to improve water across the property.
Many homeowners start with a small filter because it feels simple. A benchtop filter, fridge filter or under-sink filter can help with one outlet, but it does not treat the water used throughout the rest of the home.
That means unfiltered water may still be used in showers, bathroom taps, baths, laundry, cleaning, connected appliances and outdoor taps where applicable.
Filters water before it reaches the kitchen, bathrooms, showers, laundry and other connected areas. Best for homeowners who want a complete solution across the property.
Can improve water at one kitchen tap, but does not filter shower water, bathroom water, laundry water or other outlets.
Can help one shower, but does not address drinking water, bathroom taps, laundry, kitchen use or whole-home sediment concerns.
Useful for fridge water and ice, but limited to one appliance and usually not designed for whole-home flow rates or broader household use.
May help with drinking water convenience, but it does nothing for showers, cooking, laundry, appliances or plumbing — and it adds ongoing cost and plastic waste.
