Is Sydney tap water safe? What you need to know about PFAS, chlorine, fluoride and lead.
Short answer: yes. Sydney's tap water meets the Australian Drinking Water Guidelines. This guide explains what is actually in it, what the official test results say, and when a filter is worth having — with links to the original sources so you can check for yourself.

The short version
Safe to drink. Still worth understanding.
- Safety: Sydney Water and the NSW Government report that all Sydney supplies meet the national drinking water guidelines.
- PFAS: tested and published by Sydney Water. Levels in customer supplies are below the tighter 2025 limits.
- Chlorine: added on purpose to kill germs. Safe, but you can taste and smell it.
- Fluoride: added on purpose for teeth, at about 1.0 mg/L.
- Lead: rarely in the supply itself, but can come from older fittings inside the home.
PFAS
PFAS in Sydney water: what the testing shows.
PFAS are man-made “forever chemicals” from firefighting foam, non-stick coatings and waterproofing. In 2025 the NHMRC lowered the safe limits for PFAS in Australian drinking water — PFOS now has a limit of 8 nanograms per litre. See the NHMRC PFAS review.
In 2024, testing found PFAS in water from the Cascade plant that supplies the upper Blue Mountains. A PFAS treatment system has run there since December 2024, and Sydney Water reports the supply now meets the guidelines. The NSW Government confirms all Sydney Water supplies meet the updated guidelines. Sydney Water publishes its PFAS monitoring results and PFAS information page.
If you want PFAS lower still: reverse osmosis reduces PFOS and PFAS by up to 99%. Jug filters and basic carbon filters are not designed to remove PFAS. See our PFAS water filters.
Chlorine and chloramine
Why your water smells like a pool.
Sydney Water adds a small amount of chlorine to keep water free of germs on its way to your tap, and says it is harmless at these levels (see Sydney Water: safe drinking water). Many parts of Sydney use chloramine — chlorine combined with ammonia — which lasts longer in long pipe networks (see a Sydney Water quarterly water quality report).
What helps: a carbon filter improves taste and smell. Reverse osmosis gives the most thorough result at the kitchen tap. A whole house filter reduces chlorine taste and smell in showers and baths too.
Fluoride
Fluoride is added on purpose.
NSW Health recommends fluoride in drinking water to help prevent tooth decay. Sydney Water targets 1.0 mg/L, below the guideline limit of 1.5 mg/L (Sydney Water quarterly report; Australian Government: fluoride). Whether you filter it out is a personal choice. If you do, only reverse osmosis removes fluoride — jug filters, carbon filters and whole house systems do not.
Lead and copper
The risk is in old plumbing, not the supply.
Water from Sydney's network rarely contains lead. But some older brass fittings, taps and solder inside homes can release lead and copper when water sits in the pipes overnight (see the NHMRC lead guideline and NHMRC questions and answers on lead).
- Use the cold tap for drinking and cooking — hot water picks up more metal from fittings
- Run the cold tap for about 10 seconds first thing in the morning
- After 48 hours or more away, run it for at least 2 minutes (see NSW Health advice)
- Reverse osmosis reduces lead and other heavy metals at the drinking tap
So, do you need a filter?
Not for safety. For taste, comfort and peace of mind.

Common questions
Sydney tap water, answered.
Is Sydney tap water safe to drink?
Yes. Sydney Water and the NSW Government report that Sydney's drinking water meets the Australian Drinking Water Guidelines, including the tighter PFAS limits introduced in 2025. A home filter is an extra layer for taste and peace of mind, not a fix for unsafe water.
Is there PFAS in Sydney tap water?
Sydney Water tests for PFAS and publishes the results. Trace amounts can be detected, but all customer supplies currently meet the updated national guidelines. Reverse osmosis reduces PFAS by up to 99% if you want to remove what is left.
Why does my tap water taste like chlorine?
Sydney Water adds a small amount of chlorine, or chloramine in many areas, to keep water free of germs all the way to your tap. It is safe at these levels, but many people notice the taste and smell. Carbon and reverse osmosis filters both reduce it.
Is there fluoride in Sydney water?
Yes. Sydney Water adds fluoride on NSW Health advice to help prevent tooth decay, targeting 1.0 mg/L, below the guideline limit of 1.5 mg/L. Only reverse osmosis removes fluoride; jug and carbon filters do not.
Can lead get into my water from old pipes?
It can. The water leaving Sydney Water's network rarely contains lead, but some older brass fittings and tapware inside homes can release small amounts, especially when water has been sitting overnight. Health authorities recommend running the cold tap for about 10 seconds first thing in the morning, and only drinking from the cold tap.
Do I need a water filter in Sydney?
You do not need one for safety. People choose a filter for better taste, to cut chlorine smell in the shower, or to lower trace PFAS, fluoride and metals from household plumbing. Reverse osmosis is the most thorough option for drinking water; whole house covers every tap and shower.
