Many communities is Australia are very concerned about the possibility of the local authorities using water recycling techniques to protect water supplies from depletion during drought. In fact many communities around the world are already using water recycling successfully to reduce their water dependency, where they have to purchase water from a neighbouring state or country. Singapore is a very interesting case where they have used modern reverse osmosis technology to convert tertiary treated waste water into a high quality drinking water supply. Even in these circumstances most households in Singapore would still protect themselves by using a simple carbon water filter as a "back up" in case anything goes wrong with the water processing plant. Even in Australia water is being recycled. Waste water treatment plants along the Murray River discharge treated effluent in to the river which is then pumped out for potable water treatment plants downstream, including Adelaide! Adelaide has the saltiest and most turbid potable water supply of any capital city in Australia so a water filter is almost a necessity for every household. Water is so essential to your health, it is always wise to use a water filter as an insurance policy in case the water authority gets it "wrong" or a natural disaster causes unforeseen damage, like the recent Brisbane floods. Call PurePro if you need advice on how to protect your health by improving the quality and affordability of your drinking water. Enjoy water! Steve Brassington
