How many times have you been told that Sydney tap water is “perfectly safe to drink?” If your answer is “quite a lot,” consider this: the word “perfectly” is a pretty strong one! Because while you’re certainly not going to keel over with your next sip of water from the tap, there’s not really any doubt that you can taste chlorine, is there? So today we’re going to probe a critical question: Is Sydney tap water safe to drink?
First, the good news. All of the tap water supplied to homes in this country is subject to the Australian Drinking Water Guidelines, which concerns itself with just how much fiddling with your tap water the authorities can do. The fine print is that the guidelines are in fact “not mandatory,” even though Sydney Water – the statutory supplier of Sydney drinking water – reassures us that the filtering it does is in compliance with the guidelines, making it safe to drink straight from the tap.
Is it safe to drink tap water in Sydney?
The global water advisory authority tapsafe.org, meanwhile, deviates from the ‘perfectly safe’ narrative to inform us that Sydney tap water is in fact “generally safe to drink.” And while our water is certainly comparable to the safest tap water in the world, the same organisation admits that there is no guarantee that it doesn’t contain “a number of pollutants and contaminants.” At the same time, Sydney Water tells us that it tests Sydney tap water quality in laboratories for “70 different characteristics” – including taste, smell, colour, chemicals, and microorganisms. Among these contaminants are ‘forever chemicals,’ known for their persistence in the environment and resistance to breaking down. The Sydney tap water analysis is carried out all the way from the sources, like lakes and rivers, all the way to your tap – and according to NSW Health, “there is no such thing as naturally pure water.” That’s certainly true. In those rivers and dams and other water sources, NSW Health says Sydney’s water “dissolves or absorbs a range of substances” – most of which are “harmless.” Even so, the fact that some of them may not be perfectly harmless is precisely why Sydney tap water has been filtered with chlorine before it gets into your glass in the kitchen.
Water Treatment Processes in Sydney
Sydney’s water treatment involves several stages to ensure safety and quality. Filtration plants play a crucial role in this process, particularly in addressing the presence of PFAS chemicals in water sources. The process includes screening to remove solid objects, flocculation to clump fine particles, filtration through sand or anthracite, and disinfection using chlorine and ammonia. Fluoride is also added to promote dental health. Additionally, the Kurnell desalination plant supplements the water supply when dam levels are low, using reverse osmosis to extract freshwater from saltwater.
Regular Testing and Monitoring
WaterNSW conducts extensive monitoring of both surface and groundwater sources, tracking physical, chemical, biological, radiological, hydrological, and meteorological parameters. This ensures that any potential issues are detected early and addressed promptly. The results are made available through annual and quarterly reports.
Australian Drinking Water Guidelines
When it comes to ensuring the safety and quality of our drinking water, the Australian Drinking Water Guidelines (ADWG) are the gold standard. Developed by the National Health and Medical Research Council (NHMRC) and the Natural Resource Management Ministerial Council, these guidelines provide a comprehensive framework for managing drinking water quality across Australia.
The ADWG is grounded in the latest scientific research and undergoes regular reviews to stay current and effective. These guidelines are designed to protect public health by setting out acceptable levels for various water quality parameters, such as pH, turbidity, and bacteria. They also offer detailed guidance on the treatment processes needed to remove contaminants from drinking water and outline the monitoring requirements to ensure ongoing safety.
In essence, the ADWG covers everything from the acceptable levels of different substances in our water to the best practices for treatment and monitoring. This thorough approach ensures that the drinking water flowing from our taps is safe and of high quality, providing peace of mind for all Australians.
Chemicals in Sydney Tap Water
Sydney tap water contains disinfectants like chlorine and chloramine to neutralize pathogens. Public health warnings often highlight the presence of blue green algae, or cyanobacteria, which can affect water safety, especially during events like flooding, and emphasize the importance of boiling water as a precaution in affected areas. Fluoride is added for dental health benefits. Trace amounts of heavy metals such as lead, copper, cadmium, and arsenic can also be present due to old plumbing systems. While these are generally within safe limits, home filtration systems can further reduce their presence.
Where does Sydney get its water from?
Rainwater in five catchment areas of Sydney (Warragamba, Shoalhaven, Upper Nepean, Woronora and Blue Mountains) flows into many creeks and rivers that supply 11 major dams. The combined capacity is 2.6 million megalitres! More than 80% of Sydney’s water comes from natural sources, primarily the massive Warragamba Dam, and is treated at the Prospect water filtration plant, which meets the standards set by the Australian Drinking Water Guidelines.
Incidents and Warnings
Even with the robust framework provided by the Australian Drinking Water Guidelines, incidents affecting drinking water quality can still occur. Natural events and accidents can introduce contaminants into our water supply, necessitating swift action to protect public health.
For instance, flooding can wash contaminants into water sources, while algal blooms can produce toxins that compromise water quality. Chemical spills are another potential hazard, capable of introducing harmful substances into our drinking water.
When such incidents occur, authorities issue warnings and take necessary actions to safeguard public health. This might include boil water advisories, where residents are advised to boil their water before drinking to kill any harmful microorganisms. In more severe cases, authorities might issue “do not drink” advisories or provide alternative water supplies to affected communities.
It’s crucial to heed these warnings and follow the advice of the relevant authorities to ensure your drinking water remains safe. Staying informed and taking appropriate precautions can help protect you and your family from potential health risks.
Environmental and Health Benefits
Drinking tap water instead of bottled water significantly reduces plastic waste and energy consumption associated with production and transportation. Fluoride in tap water helps prevent tooth decay, contributing to dental health. Tap water is cost-effective, promotes dental health due to fluoride content, and is subject to stringent quality controls that often surpass those for bottled water.
Dealing with Discolored or Odd-Tasting Water
Discoloration often results from sediment stirred up by changes in water flow or pressure. Running a garden tap for a few minutes can help clear this. If discoloration persists, contact local authorities for assistance. For unusual tastes or odors, consider using a home filtration system to improve water quality. Using filtered water can help eliminate traces of contaminants, providing safer and better-tasting water, especially in areas with water quality challenges.
Thinking about Water Filter Installation?
Heard enough? Sure, you could go your entire life drinking tap water Sydney wide and never run into trouble – but on the other hand, you could play it safe by filtering tap water to remove contaminants and improve taste, and order the best possible water filter installation known to man! In Australia, that just so happens to be reverse osmosis water filter technology – and here are 4 reasons to consider getting one fitted asap:
- No tap water is pure: Your water may look pure but isn’t necessarily. The pipelines could be full of contaminants – a filter removes them at point-of-use.
- Save money: If you’re worried about contaminants and solved it by drinking bottled water, a filter will pay for itself quickly while reducing plastic waste.
- Bye-bye chlorine: Chlorine disinfects but isn’t designed for consumption! A filter removes chlorine before you drink it.
- Better taste: Say goodbye to chlorine or metallic tastes with a filter.
How Does Sydney Compare?
Sydney’s tap water is generally considered high quality due to rigorous treatment processes. The Public Health Act 2010 mandates suppliers to implement quality assurance programs to ensure the safe supply of drinking water, which is routinely monitored under a comprehensive Drinking Water Monitoring Program. However, taste can vary compared to other cities like Melbourne, which often receives praise for its superior tap water quality. Factors such as source protection and treatment methods contribute to these differences.
