Gold Coast tap water quality
Gold Coast residents are supplied by the South East Queensland water grid โ the same treatment and distribution network that supplies Brisbane. This means the primary water quality characteristic is the use of chloramines (a combination of chlorine and ammonia) rather than free chlorine as the primary disinfectant.
This matters for filter selection. Standard activated carbon filters are designed primarily for free chlorine removal. Chloramines require either catalytic carbon (a specific activated carbon medium designed for chloramine reduction) or a carbon block specifically rated for chloramine removal. If your Gold Coast filter uses standard GAC, it may not be removing the chloramines responsible for the taste and odour you're experiencing.
If you're on the Gold Coast or anywhere in SEQ and your filter isn't noticeably improving your water taste, it's likely a standard carbon filter that is not effective for chloramines. Ask specifically for a catalytic carbon or chloramine-rated carbon block when requesting quotes โ any experienced local installer will know this.

Getting quotes on the Gold Coast
- Ask specifically for catalytic carbon or chloramine-rated cartridges โ standard carbon is insufficient for SEQ water
- Confirm WaterMark certification on all products before installation
- For hinterland properties on tank water, ensure UV is included in any whole house system quote
- Get at least 2 quotes โ pricing varies between suppliers for equivalent systems
SEQ water uses chloramines, not free chlorine. Standard carbon filters remove free chlorine very effectively but are much less effective on chloramines. If you can still taste or smell your filtered water, the most likely cause is a standard carbon cartridge that isn't designed for chloramine removal. Ask your supplier for a catalytic carbon or specifically chloramine-rated replacement cartridge.
