Caravanning is a popular means of enjoying a relaxing and affordable holiday, or as a way of exploring Australia’s wide open spaces, especially for “Grey Nomads” or young families. It can also be a means of cheap accommodation when work is seasonal, such as fruit picking, or for tourists or ordinary Australians on a working holiday. Because Australia’s population is clustered around the coastline, travellers venturing away from the coast can often find themselves in uninhabited areas where there are very few sources of clean, potable drinking water. Adults need to drink at least 2 litres of water per day and in hot humid or hot dry areas we may need up to 5 litres of water per day to prevent dehydration. When you are planning a caravan trip, don’t forget to make allowances for the amount of water needed by each person per day and then add an extra 20 litres, as a safeguard against problems you might encounter such as accidents or breakdowns. There is a large range of different water tanks available in Australia that are suitable for caravans. Choosing the right one will depend on the size of your caravan, the number of people traveling with you and the amount of space you have available. Tanks can be as simple as a 22 litre plastic jerry can or a 180 poly tank specially moulded to be mounted under the caravan. Food Grade, UV stabilised polyurethane is a popular choice for caravan water tanks because it is unbreakable, light and can be moulded into a variety of shapes to suit almost any location. It is also relatively inexpensive and can store water safely and securely for long periods of time. ALKO, AMPAC and FIAMMA are some of the brands available. You might choose a variety of water tanks for your caravan, a portable jerry can plus a large tank mounted underneath the caravan and a slimline mounted inside to give you an adequate supply of water. Slimline tanks are useful for narrow spaces and, if mounted inside the caravan, reduce the sloshing noise associated with carrying large amounts of water. When you have chosen your tank or tanks, don’t forget to include the appropriate tank accessories, such as a simple water tank gauge, perhaps a pump and the correct kind of hose to connect to your drinking water outlet. While poly tanks are common, dedicated travellers may go to the expense of fitting stainless steel water tanks. Remember that water is very heavy to carry, and that whatever material your tank is made from, it needs to be securely mounted on a strong stable surface to prevent mishaps when on the road. Sometimes the water stored inside the tank can acquire an unpleasant taste. This can be due to choosing the wrong connecting hose, allowing algae to build up inside the tank, or refilling the tank with bore water or untreated river or spring water. Cleaning your tank regularly, choosing the correct fitting and using filtration systems will eliminate these problems.
