Drinking Water Private
People in rural areas of the ACT who have rain-water tanks or other private water supplies need to ensure that their water supply is safe.
There may be particular issues for water supplies in fire-affect areas, in addition to normal health-related issues which pertain to rainwater tanks.
Water from rainwater tanks or deep bores is usually safe to drink. However, it can sometimes be contaminated by human, bird or animal faeces, usually from leaking septic tanks, wastewater drainage or bird or animal droppings on roofs.
Local streams may also be contaminated by runoff washed from farmyards, pastures and drains, making them generally unsuitable as a source of drinking water unless the water is properly treated.
Contaminated water may contain harmful micro-organisms, such as viruses, bacteria (such as salmonella or campylobacter) and gastro-intestinal parasites (such as giardia or cryptosporidium). These harmful micro-organisms, known as pathogens, are not visible to the naked eye and may even be present in relatively clear water.
Drinking water containing these micro-organisms can cause severe gastro-enteritis, possibly lasting for several weeks. Infants, the elderly and people with suppressed immune systems are most likely to be affected.
Serious outbreaks of gastro-enteritis have occurred in some Australian states as a result of people drinking contaminated water. However, the risk of contracting these illnesses from water can be very greatly reduced by obtaining your drinking water from a clean, good quality source and regularly maintaining your water supply system.
Chemical contaminants are usually less common than microbiological contaminants, but they can still be present in the rural environment.
For example, soil from old industrial, mining or agricultural areas may contain arsenic, heavy metals, pesticide residues or other chemicals.
If dust is blown onto your roof and is washed into your rainwater tank, chemical residues may build up in the water. Runoff from roofs in urban or industrial areas may also contain chemical pollutants from the air.
