Cairns Natural Spring Water is sourced from a unique and ancient underground water source located in the Mulgrave area of Cairns, nestled within the lush Wet Tropics region of Far North Queensland. This pristine source is found just south of Cairns and spans the entirety of the alluvial plain, extending from the southern side of Trinity Inlet to areas like Edmonton, Greenhill, and Gordonvale. The Mulgrave Aquifer, which lies beneath this vast area, also runs along the entire stretch of the Mulgrave River Valley, from Little Mulgrave to Russell Heads.
Over thousands of years, the aquifer sections beneath the Mulgrave River have been formed through the gradual accumulation of sedimentary deposits. These deposits, which loosely hold the underground water, were amassed due to the movements and floods that took place across the valley during that extensive period. Interestingly, the deposits located north of Greenhill (north of Gordonvale) date back to the bygone millennia when the Mulgrave River flowed in a different direction, running northward into Trinity Inlet instead of its current path southward to Mutcheroo Inlet.
All of these unique factors come together to create the refreshing and pure Cairns Natural Spring Water that we know and love today, making it a truly one-of-a-kind and sought-after natural resource.
Our water is part of the Earth’s hydrologic cycle, which is the continuous circulation of moisture and water on our planet. This cycle is in constant operation, moving water from the Earth to the atmosphere by evaporation and back again to the Earth’s surface as precipitation.
Did you know that the water that falls to the Earth’s surface in the form of rainfall goes to many different places? Some runs off the surface, some evaporates back to the atmosphere and some infiltrates into the ground. Part of the water that moves into the ground is taken up by plant roots and re-enters the atmosphere through transpiration. The rest percolates deeper into the Earth and becomes ground water. This water is held in aquifers and it is from these that we pump.
The word aquifer comes from the Latin words aqua, meaning water, and ferre, meaning to bear or carry. Thus an aquifer is a water-bearing geologic formation. An aquifer may be a layer of gravel or sand, a layer of sandstone or limestone, or even a body of massive rock, such as granite, which has sizeable cracks and fissures. Some of the most productive aquifers in Far North Queensland, like ours, consist of sedimentary rocks such as limestone, dolomite and sandstone, and these contain naturally occurring minerals in varying concentrations that give our water its unique characteristics.
Our water is analysed by an independent NATA-certified laboratory.
Our commitment to our customers is to deliver safe, healthy and pure water in every bottle we produce. To achieve this we operate a stringent quality control regime.
Here at Cairns Natural Spring Water, we take two very important steps to ensure removal of physical and bacterial contamination before filling our bottles:
Firstly, the water is drawn up from the aquifer in a network of sealed pipes, meaning it does not see the light of day until it is in a capped and sealed bottle. Our state-of-the-art filters remove bacteria and endotoxins to a 0.2 micron absolute rating.
The next step is ultraviolet sterilisation to remove any residual bacteria and viruses, making sure our bottles are completely clean and ready for use. We use only the best filter cartridges and fittings and some of the most popular and dependable bottling systems available, ensuring comprehensive wash and sterilisation and automatic washing, filling and capping.
We are regularly inspected by the Queensland Department of Health to ensure we remain fully compliant with the highest standards that we ourselves and our customers have come to expect of us. Similar inspections are made to ensure our continuing compliance with Workplace Health & Safety legislation.
