Keeping any kind of farming operation efficient and profitable during the arid, drought-prone months of summer require prodigious amounts of water, and many farms across the country have their own private water bores to provide a reliable source of fresh, uncontaminated water when centralised supplies are limited. However, the water you draw from these deep bores needs to be stored safely when not in immediate use, and most water bore systems are equipped with large water tanks.
If you are choosing a water tank for your new water bore, the material your tank is made from will have a huge influence on its long term effectiveness. Polyethylene water tanks are a popular choice—and for good reason. These redoubtable plastic tanks have a number of advantages over high-capacity tanks made of other materials that make them an ideal choice for bore water storage:
Polyethylene is one of the most tough and durable plastics in widespread use, and a well-made polyethylene water tank can withstand years of heavy use in unsheltered locations. Unlike other plastics, polyethylene does not degrade when exposed to prolonged, intense sunlight, an obvious advantage for tanks designed to mitigate the effects of summer droughts. Polyethylene tanks are also rustproof, unlike galvanised steel tanks, and are much more resistant to ground tremors and shifting soils than concrete tanks.
Since polyethylene water tanks do not have any problems with rust, they only need to be inspected for damage and degradation on a very infrequent basis. Empty tanks can be kept clean and free of algae using ordinary cleaning compounds.
Unlike steel, aluminium and fibreglass tanks, polyethylene tanks are not assembled from individual sections, but are manufactured as one-piece units in large moulds. This manufacturing method means polyethylene tanks are seamless, and consequently immune to the pinhole leaks and cracks that often form along the seams of assembled high-capacity water tanks as they age. Their resistance to corrosion and ground movement also contributes to their excellent leak resistance, ensuring your valuable stored water is not wasted before you need it.
High-capacity tanks are naturally rather weighty, but polyethylene tanks are much lighter than steel, concrete or aluminium alternatives. This makes them cheaper and easier to transport to isolated farms and also ensures ease of installation without the need for cranes and other heavy-duty lifting equipment. Their relatively low weight also ensures that they can be installed without the need to extensive (and expensive) concrete foundations.
Despite all of these advantages, high-capacity polyethylene tanks are relatively inexpensive, especially when compared with tanks of equivalent capacity made from stainless steel or concrete. These low prices are particularly useful if you intend to install multiple tanks to store particularly large amounts of water.Share
