Water tanks and dams – safety tips

Water tanks, dams and channels on farms are an essential source of water for drinking, livestock and irrigation needs. However they can pose serious risks. Children can drown in tanks and dams, water can be contaminated and accidents can happen when tanks are being cleaned.

Tanks can also become breeding areas for mosquitoes which is a particular concern in areas where mosquito borne diseases like Murray Valley encephalitis virus, Ross River virus, Barmah Forest virus and Dengue fever are a risk.

Protect you and others: 

Seal water tanks so children, animals, birds and insects can’t get in.
Clean water tanks regularly but use safety precautions—ie make sure someone knows you are in there. Be careful using motorised pumps in confined spaces such as tanks. People have become asphyxiated.

Ensure a safe and fenced off play area for children and always keep an eye on children near dams, troughs swimming pools, creeks and tanks.

If you obtain your drinking water from bores, rivers, dams or rainwater tanks, you should take special care to make sure that this water is safe to drink. Contaminated water can cause serious illness, from nutrient build up, bacteria, agrichemicals, bushfire ash and algal blooms such as blue green algae. Water from hoses can also be dangerous particularly if it has been sitting in the hose and becomes warm thus enabling bacteria build up.
