How practical are rainwater tanks?
The rainfall patterns and climate are constantly changing. They are all part of a larger global picture. Unfortunately, when changes arise, we must equally adapt. Rainwater tanks are a solution to the inconsistent water supply in Australia. They offer a cheap, practical alternative that guarantees an uninterrupted supply of clean water to your taps. Water tanks are a huge investment and a good return on investment is crucial. Fortunately, tanks have always proven to be beneficial to homeowners and businesses. The pros outweigh the cons despite the simplicity of the fitting.
Water tanks come in different shapes and sizes. Many options are available on the market and the selection is dependent on customer preference. Water storage can be done through above-ground tanks or underground water tanks. Each of the alternatives has their advantages and disadvantages. Customer requirements and the cost implication are some of the main driving factors when it comes to selection.
Underground rainwater tanks
If the water storage requirements for your residence are high, an underground rainwater tank is the best practical solution. Underground tanks can handle large water capacities. Some underground tanks are buried polyethylene tanks while others are made from concrete. The polyethylene tanks are manufactured in different sizes and limited in specifications. The size of underground concrete tanks is only limited to your requirements. The tanks can go as deep or as wide as you want. The determinant is the space available. The big tanks require a lot of concrete reinforcement to withstand the high pressure of the water they hold. Moreover, concrete tanks that are sunk deep into the ground need extra reinforcement to endure the large pressure from the earth.
Underground water tanks are also a great solution for those who want to conceal their water storage units. Underground tanks are buried deep in the ground to keep them out of sight. Consequently, you retain the aesthetic value of your property. Above-ground water tanks distort the exterior design of a house. They stick out as an eyesore and take up too much space. However, underground tanks allow you to maintain your lawn. The depth of the earth over buried tanksallows plants to grow on the soil. Moreover, the tanks allow proper utilisation of space. Instead of wasting space installing an above-ground rainwater tank, you can use an underground tank and save on space.
Above-ground rainwater tanks
Above-ground water tanks are a popular installation in many Australian homes. The most popular tanks are made from steel or polyethylene. They come in different sizes and shapes ranging from large steel tanks to small polyethylene tanks. The capacity of the tanks can extend to over 50,000 litres. However, such large tanks require proper support to bear their weight. An average home can harvest up to 100,000 litres of rainwater in a year from the roof. If you only need to collect rainwater to flush toilets and do the laundry a 9,000-litre tank is enough to meet your needs. However, if the rain pattern in your area is interrupted by long periods of drought a bigger tank would be a prudent choice. Moreover, if you want to harvest rainwater for a variety of uses a large storage unit would be the best investment.
When considering the practicality of water tanks, you have to look at the cost. Above-ground water tanks are cheap. The units are affordable, and the installation process doesn’t require too much money. On the other hand, underground tanks are expensive to build. Concrete tanks require a building plan and heavy investment in the installation process. Since rainwater is a free resource a large storage unit is only as valuable as your water requirements. Rainwater can be utilised for drinking, to supplement the water used in gardens, or reduce reliance on mains water. No matter the need, rainwater tanks are a practical investment worth pursuing. Both above-ground tanks and underground tanks have their own pros and cons, but they are good investment all the same.
