Is Warrnambool tap water safe to drink?

Yes. Warrnambool and South-West Victoria tap water is supplied by Wannon Water, which treats and tests it to meet the Safe Drinking Water Act and the Australian Drinking Water Guidelines. It is disinfected, fluoridated at the recommended level, and safe to drink straight from the tap. A filter is a preference, not a necessity.

Yes. Wannon Water is legally required to meet the Safe Drinking Water Act 2003 and the national Australian Drinking Water Guidelines, and it tests the supply regularly from source to tap. If the water did not meet the standard, they would have to tell you. It is safe to drink straight from the tap.

That is the honest starting point for this whole topic. Everything else, taste, smell, skin, appliances, is about preference and comfort, not safety.

How is Warrnambool's water treated?

Depending on the source, Wannon Water uses disinfection (chlorine, chloramine and UV), filtration, clarification and pH adjustment. Disinfection is the key safety step, killing bugs like E. coli that are the main health risk in drinking water. They also test for metals, pesticides and disinfection by-products against national limits.

It is a multi-barrier approach, so if one step has an issue the others cover it. That is why the tap water is reliably safe day to day.

Beyond safety, the two questions people ask most are about fluoride and PFAS, so here is where each one stands locally.

Is there fluoride in Warrnambool water?

Yes. Warrnambool's water is fluoridated at the recommended level of about 1 milligram per litre (one part per million), on Victorian Government direction and endorsed by the NHMRC, to help prevent tooth decay. It does not change the taste, smell or colour of the water.

Whether you keep or reduce fluoride is a personal choice. Worth knowing: a standard whole-house filter does not remove it, which we cover in our fluoride article.

Does Warrnambool water contain PFAS? Wannon Water tests its supplies for PFAS and reports all its drinking water complies with both the current and the updated national guidelines (the NHMRC tightened the PFAS values in 2025). In plain terms, the local supply is considered safe on PFAS, so you are not starting from an unsafe position.

Some filter systems reduce PFAS as an added feature, but that is peace of mind rather than fixing a known local problem. Check Wannon Water's annual water quality report for the latest figures.

Victoria is actively transitioning away from gas. New builds are adopting all-electric systems, and many existing homes with gas hydronic systems are considering their next steps. O’Brien Electrical & Plumbing Warrnambool designs and installs custom air-to-water heat pump hydronic systems using the Maxa Monoblock solution. These systems are ideal for high-end residential properties and homeowners seeking comfort, efficiency, and long-term energy management. Hydronic heating and cooling is a tailored system, designed to suit your home, lifestyle, and energy objectives. What Is Air to Water Hydronic Heating and Cooling? An air to water heat pump extracts heat from outside air and transfers it to water, which is then circulated through: In slab hydronic pipework for heating Radiators or towel rails Fan coil units for both heating and cooling During summer, the system reverses, circulating chilled water through fan coils for quiet, efficient cooling. Unlike traditional split systems that use refrigerant gas inside the home, hydronic systems use water as the primary heat transfer medium. This distinction is important. Why Water Is a Superior Heat Transfer Medium From an engineering perspective, water is one of the most effective mediums for transferring heat. Water has a much higher specific heat capacity than air. This means it can carry significantly more thermal energy per unit volume. In simple terms, water moves heat more efficiently and consistently than air or refrigerant-based systems, circulating warm air throughout a space. This results in: More stable indoor temperatures Less temperature fluctuation Lower energy input for the same comfort outcome Reduced system strain and longer equipment life Because water retains heat well, hydronic systems provide gentle, even warmth rather than intermittent hot air. The result is quieter, more consistent, and refined comfort in Victoria. Victoria is leading the shift away from gas. With rising gas prices, network changes and increasing pressure to electrify homes, many households with older gas boilers are now facing a decision. Will you replace gas with another gas system, or choose to future-proof your home? For many clients in Warrnambool and South West Victoria, upgrading to an electric air-to-water heat pump system is a logical choice. This eliminates gas from the heating process and aligns the home with an all-electric future. If you already have hydronic pipework installed, we can, in many cases, design a system that integrates with your existing infrastructure, replacing the gas boiler with a high-efficiency electric heat pump. Hydronics as Part of a Complete All-Electric Ecosystem We approach heating and cooling as part of a comprehensive solution. At O’Brien Electrical & Plumbing Warrnambool, hydronic heating and cooling form part of a broader, integrated energy ecosystem that can include: Solar panels Battery storage Heat pump hot water systems EV charging Smart energy monitoring A properly designed solar system can generate the electricity needed to operate your hydronic heat pump. With battery storage, you can use excess solar energy for heating in the evening or cooling during peak times. The goal is simple. We aim to design a system that minimises your energy bills while maintaining grid connection for security and backup power. This is where bespoke design becomes essential. Why Bespoke Design Makes the Difference Hydronic systems are not off-the-shelf products; each property has unique requirements. High end residential builds in Warrnambool, rural homes outside Terang, and coastal properties near Port Fairy all have different thermal loads, insulation levels, glazing types and occupancy patterns. We assess: Building orientation Insulation levels Window performance Heat load calculations Lifestyle usage patterns Existing electrical infrastructure From there, we design a Maxa Monoblock air-to-water system sized correctly for your home. Not oversized. Not undersized. Design. As a combined electrical and plumbing provider, we manage the entire system in-house. This ensures seamless coordination, clear responsibilities, and optimal integration of heating, cooling, and renewable energy systems. You work with a single team, one cohesive design, and a unified outcome.
