Water Filtration in Melbourne's Western Suburbs: What Homeowners Need to Know
If you live in Melbourne’s western suburbs and have noticed that your tap water tastes different, smells chemical, or leaves your skin feeling dry after a shower, you are not imagining it. The water supply across Tarneit, Werribee, Point Cook, Truganina, Melton, Wyndham Vale, and surrounding suburbs is treated with chloramine rather than chlorine. This makes a real difference to how the water tastes, how it affects your skin and hair, and critically, what type of water filter you need to remove it.
Chloramine is a combination of chlorine and ammonia that Greater Western Water uses as a long-lasting disinfectant across its supply network. It is effective at keeping water safe over long pipe runs, which is necessary in the rapidly growing suburbs of Melbourne’s west. But it also means your water carries a persistent chemical residual that standard jug filters and basic tap-mounted filters are not designed to handle.
This guide covers the specific water quality situation in Melbourne’s western suburbs, explains why chloramine matters, confirms what filtration options work in this area, and outlines exactly what it costs to get clean, filtered water at every tap in your home. Select Plumbing and Gas services all of Melbourne’s western suburbs, and this page confirms we are available in your area.
Why the Water in Melbourne's Western Suburbs Tastes and Smells Different
The difference in water quality in Melbourne’s west comes down to one thing: the disinfectant. While most of Melbourne’s eastern and south-eastern suburbs receive water treated with chlorine, the western suburbs receive water treated with chloramine.
Here is why that matters for your household.
Factor | Chlorine (Eastern/SE Suburbs) | Chloramine (Western Suburbs) |
How it works | Free chlorine is added at the treatment plant. Dissipates over distance. | Chlorine bonded with ammonia. Persists much longer in the pipe network. |
Taste and odour | Noticeable chlorine taste, especially close to the treatment plant. Fades over time. | Persistent chemical taste and smell that does not dissipate as readily. |
Skin and hair effects | It can cause dryness with prolonged exposure. | Same drying effects, but chloramine is present at consistent levels across the network. |
Basic jug filter | Effective at reducing chlorine taste | Not effective. Standard activated carbon cannot break the chlorine-ammonia bond. |
Whole-house carbon filter | Effective | Effective only if the system uses composite carbon or catalytic carbon designed for chloramine. |
Reverse osmosis | Effective | Effective. The carbon pre-filter stages in a quality RO system handle chloramine before the membrane. |
The key point: if you live in Melbourne’s western suburbs and you have been using a basic jug filter or tap-mounted filter, it is likely not doing much against chloramine. You need a system specifically designed for your water supply.

Not sure who supplies your water? Check the retailer name on your water bill. If it says Greater Western Water, your water contains chloramine.
What Type of Water Filter Works Best in the Western Suburbs?
Because of the chloramine issue, not every water filter on the market is suitable for Melbourne’s western suburbs. Here is what works, what partially works, and what does not work for a Greater Western Water supply.
Filter Type | Chloramine Removal | What It Covers | Verdict for Western Suburbs |
Basic jug/pitcher filter | No | Drinking water only, small capacity | Not recommended. Will not remove chloramine from your water. |
Tap-mounted filter | Limited | Single kitchen tap only | Minimal improvement. Most tap filters use basic carbon that cannot break down chloramine. |
Benchtop gravity filter | Some models | Drinking water only | Check the specifications carefully. Only models with catalytic carbon handle chloramine. |
Whole house filter (HP3 with composite carbon) | Yes | Every tap, shower, and appliance in your home | Recommended. The HP3 system includes a 0.5 micron composite carbon stage designed for chloramine. |
Under sink reverse osmosis (7-stage) | Yes | Drinking and cooking water from one tap | Recommended. Carbon pre-filter stages handle chloramine before the RO membrane. |
Both systems (dual install) | Yes | Complete home coverage plus pure drinking water | Best option. Filtered water everywhere, plus 98% contaminant removal for drinking water. |
The HP3 whole-house water filter that Select Plumbing installs uses a 304 stainless steel housing with a multi-stage cartridge that includes a 0.5 micron composite carbon block. This stage is specifically effective against both chlorine and chloramine, which is why we recommend it for every home in Melbourne’s western suburbs.
If you also want the purest possible drinking water for your family, adding a 7-stage reverse osmosis system under the kitchen sink removes up to 98% of all dissolved contaminants, including fluoride, heavy metals, and dissolved solids that a carbon filter alone cannot reach. Our comparison guide explains when you need one, the other, or both.
How Much Does Water Filtration Cost in the Western Suburbs?
Pricing is the same across all of Melbourne, including the western suburbs. There are no additional travel charges or zone-based fees for Tarneit, Werribee, Point Cook, Truganina, Melton, or any suburb within our service area.
System | Installed Price | Annual Filter Cost | 3-Year Total |
Whole House Filter (HP3) | $1,100 | $350 | $1,800 to $1,900 |
Under Sink RO System (7-stage) | $1,100 | $150 to $200 | $1,400 to $1,500 |
Both Systems (Dual Install) | $2,200 | $500 to $550 | $3,200 to $3,400 |
Each price includes the complete system, all fittings, professional installation by a licensed plumber, and pressure testing. For a full breakdown of what is included, see our whole-house water filter cost guide and reverse osmosis cost guide.
0% interest finance is available for eligible customers. This lets you spread the cost over manageable weekly or fortnightly payments with no penalty for early repayment. At roughly $20 to $25 per week on a finance plan, a whole-house filter costs less than what most families spend on bottled water.
New Homes in the Western Growth Corridor: Why Filtration Matters From Day One
Melbourne’s western suburbs are among the fastest-growing residential areas in Australia. Suburbs like Tarneit, Wyndham Vale, Manor Lakes, Aintree, Rockbank, and Truganina are filled with new housing estates where hundreds of families are moving in each year.
There is a common assumption among new homeowners that brand-new plumbing means clean water. The plumbing inside your new home is indeed new, but the water flowing through it still comes from the Greater Western Water supply network and still contains chloramine. New pipes do not filter anything.
Here is why new homeowners in the western suburbs should consider water filtration early.
- Chloramine is in your water from the first day you turn on the tap. New plumbing does not change what is in the supply.
- New housing estates sit at the end of long pipe runs. This means the water has travelled a significant distance through the distribution network, picking up sediment and maintaining high disinfectant residual levels.
- Building dust and construction residue can remain in your home’s plumbing for weeks after handover. A sediment filter catches these particles before they reach your taps and appliances.
- Hot water systems, dishwashers, and washing machines all perform better and last longer with filtered water. Sediment and chemical residue contribute to scale buildup and premature wear on seals and heating elements.
- Installing during or immediately after the build is easier and cheaper because the plumbing is still accessible. Our renovation and new build guide explains why timing matters.
The Bottled Water Problem in the Western Suburbs
It is extremely common for families in Tarneit, Werribee, Point Cook, and surrounding suburbs to buy bottled water because they dislike the taste of their tap water. We hear this regularly from leads in the area. The problem is that bottled water is one of the most expensive ways to get clean drinking water.
Timeframe | Bottled Water (Family of 4) | Whole House Filter |
Year 1 | $1,040 to $1,820 | $1,100 (installation) |
Year 3 | $3,120 to $5,460 | $1,800 to $1,900 |
Year 5 | $5,200 to $9,100 | $2,500 to $2,700 |
Year 10 | $10,400 to $18,200 | $4,250 to $4,600 |
Over 10 years, the savings range from $6,000 to $13,600. And a whole-house filter does something bottled water cannot: it filters your shower water, laundry water, and the water flowing through your hot water system and appliances. Bottled water only covers drinking. For a deeper dive into this comparison, see our guide on how to stop buying bottled water.
What Does a Water Filter Remove From Western Suburbs Tap Water?
A whole-house water filter installed on a Greater Western Water supply removes:
- Chloramine (the primary disinfectant used in your area)
- Sediment, sand, and rust particles (common after mains work or during high-demand periods)
- Heavy metals, including lead and copper (from older distribution mains and brass fittings)
- Pesticides, herbicides, and volatile organic compounds (trace levels from catchment and agricultural runoff)
- Taste and odour compounds (the chemical taste that makes many Western Suburbs residents switch to bottled water)
- Disinfection byproducts (trihalomethanes) (formed when chloramine reacts with organic matter in the pipe network)
If you add an under-sink reverse osmosis system for the kitchen tap, you also remove fluoride, dissolved salts, and up to 98% of total dissolved solids. This gives you pure, mineralised drinking water through a dedicated tap. For a complete breakdown, see what a whole-house water filter removes and how reverse osmosis works.

Frequently Asked Questions
Does Greater Western Water use chloramine?
Yes. Greater Western Water uses chloramine (chlorine combined with ammonia) as the primary disinfectant across its supply network. This covers suburbs including Tarneit, Werribee, Point Cook, Truganina, Melton, Wyndham Vale, Sunbury, Bacchus Marsh, and surrounding areas. Chloramine persists longer than chlorine in the pipe network, making it effective for large supply areas but also leaving it present at noticeable levels when it reaches your tap.
Will a jug filter remove chloramine from my tap water in the western suburbs?
No. Most jug filters and pitcher filters use basic activated carbon, which is effective at reducing chlorine but cannot break the chlorine-ammonia bond in chloramine. If you live in an area supplied by Greater Western Water, a jug filter will have minimal effect on the chloramine taste in your water. You need a filter with composite carbon, catalytic carbon, or a reverse osmosis membrane to remove chloramine effectively.
How much does a water filter cost in Tarneit, Werribee, or Point Cook?
A whole-house water filter costs $1,100 fully installed, including GST. An under-sink reverse osmosis system also costs $1,100 to install. If you want both, the total is $2,200. These prices are the same across all Melbourne suburbs, including the western suburbs. There are no additional travel fees or zone-based charges. 0% interest finance is available for eligible customers.
Do you service Tarneit, Werribee, Point Cook, Truganina, and Melton?
Yes. Select Plumbing and Gas services all of Melbourne’s western suburbs, including Tarneit, Werribee, Point Cook, Truganina, Melton, Wyndham Vale, Williams Landing, Hoppers Crossing, Manor Lakes, Sunbury, Bacchus Marsh, Aintree, Rockbank, Caroline Springs, Deer Park, and all surrounding suburbs: same pricing, no travel fees.
What is the best water filter for Melbourne's western suburbs?
For homes supplied by Greater Western Water, we recommend a whole-house water filter with a composite carbon stage that is rated for chloramine removal. The HP3 system we install uses a 0.5-micron composite carbon block in a 304 stainless steel housing, designed to handle both chlorine and chloramine. For the purest possible drinking water, add a 7-stage reverse osmosis system under the kitchen sink.
Is the water in Melbourne's western suburbs safe to drink without a filter?
Yes. Water supplied by Greater Western Water meets the Australian Drinking Water Guidelines and is safe to drink by regulatory standards. However, it does contain chloramine, fluoride, and potentially trace levels of sediment and disinfection byproducts. Many residents of the Western Suburbs find the taste unpleasant and choose to filter their water for better taste, reduced chemical exposure, and improved water quality for showering and laundry. Our guide on whether Melbourne tap water is safe covers this in full detail.
