Melbourne tap water quality
Melbourne water has a reputation for good quality — relatively soft, low mineral content, and sourced from protected catchments in the Yarra Ranges. Chloramination is used in the distribution system. Generally one of Australia's better tap water supplies.

Getting quotes in Melbourne
Getting 2–3 quotes from different suppliers in Melbourne is the most important step before committing. Filter installation pricing varies between generalist plumbers and dedicated water filter specialists — and the quality of system specification advice varies even more.
- Confirm WaterMark certification on any product before purchase or installation
- Ask for an itemised quote — unit cost, installation, tap (if required), and ongoing cartridge costs separately
- Confirm the plumber holds a current licence for your state — check the relevant licensing board
- Ask specifically what the system removes — get a specification sheet, not just a brand name
For most Melbourne homeowners on town mains water, an under-sink carbon block filter or a 5–7 stage reverse osmosis system is the most popular choice for drinking and cooking water. Whole house systems are more common among homeowners with VIC bore or tank water sources, or those specifically concerned about chlorine in shower water. See our filter types guide for help choosing.
