What is in our water?
Drinking water contains naturally occurring minerals such as calcium, sodium and magnesium. The levels of these minerals can vary causing very slight differences in taste, odour and colour.
'Hard' drinking water is mainly the result of high levels of calcium and magnesium and makes it difficult to work up a lather or suds for washing.
Unlike many parts of the world where water is ‘hard’, our water has very small amounts of calcium and magnesium and is referred to as ‘soft’ water. You do not need to add salt to appliances to soften the water as recommended by many European manufacturers, and appliances can be left on the factory default settings.
Please see our Water Quality Reports for water hardness results in your area.
NOTE: Often dishwasher suppliers quote hardness results in mmol/L. The conversion is 1mmol/L = 100mg/L.
Drinking water also contains sodium. While the contribution of drinking water to dietary sodium intake is usually very low, persons on a very low sodium diet should be aware that Unitywater’s drinking water typically contains between 20 and 50 milligrams (0.02 to 0.05 grams) of sodium per litre of water.
To provide safe drinking water the addition of a disinfectant is necessary. There are two main chemicals used to disinfect drinking water supplies throughout Australia – chlorine and chloramine. A small amount of residual disinfectant is generally present in your drinking water once it reaches your tap.
At Unitywater we carefully monitor disinfectant levels to ensure the microbiological safety of your drinking water, while trying to minimise the associated taste and odour.
Be aware that the taste of chlorine in your water may become more or less noticeable at different times of the year, and this is nothing to be concerned about. Unitywater will often boost chlorine levels during the warmer summer months to prevent the regrowth of ‘nuisance’ micro-organisms.
You can eliminate any taste or smell of chlorine by simply filling an uncovered container with tap water, placing it on the bench, and letting it sit overnight. An even quicker way is to add a slice of lemon, which reacts with chlorine instantaneously (and it also tastes great!). Alternatively, you might want to consider domestic water filters or jug filters.
Aquarium owners - tap water should be aged prior to adding to any fish tank or aquarium due to the disinfectant present in tap water. Always age the “new” tap water by either adding a water ager product available from pet stores or by leaving water out in a separate uncovered container for a couple of days, before adding it to the fish tank. Replace less than one third of the total volume of water in the aquarium at any one time. Refer to your local pet store for all other enquiries.
The Queensland State Government made the decision to add fluoride into Queensland’s water supplies. Fluoride is added to water via the water treatment plants, which are now owned and operated by Seqwater, a Queensland State Government entity.
