Rain water harvesting for farmers

South Africa is a particularly water scarce country, leaving it in a perilous position when met by drought like in recent months. A viable solution to help save water and aid dams the opportunity to refill themselves and recover, is through rain water harvesting.
Water tanks are self-sufficient and made to work with the environment. Rainwater tanks are a fundamental invention and have been used for many years. In today’s times, water tanks continue to benefit farmers and various other industries as well as for domestic use. According to many a research study, rainwater has proven to be naturally clean and chemical free. In the instance of farmers, water for irrigation is a luxury in times of drought and in traditionally dry areas. By saving and storing water during the rainy season one can provide much needed irrigation for land when the seasons change.
South African based Roto Tank produces polyethylene tanks which are ideal for rainwater harvesting. According to the company these polyethylene tanks are lighter than the stainless steel alternative, making them easier to transport and unaffected by corrosion and rust, which may render water unusable in certain circumstances.
Furthermore, Roto Tank has introduced a combination of water tanks and troughs for efficiency. Water troughs, have a variety of uses on the farm and can work in conjunction with water tanks for optimum results. Says Roto Tank: “Many farmers make use of rainwater harvesting methods in order to save on water expenses. Water collects into various water tanks during rainfall. Farms in general consist of hectares of land and farmers harvest water by making use of water tanks fitted to a trough at the bottom tank that will allow water to be available for animals to drink. Some of our troughs can hold more than 800 litres of water at a time. Moreover water can also be treated with nutrients and medication and used in a livestock water trough. Various animals can drink from the trough including horses and ostrich.
The ball valves present in the water tank and trough will ensure that water levels remain constant. The ball valves are tamper proof and secure from any potential damage caused by livestock.”
Jojo Tanks, a world renowned manufacturer of water tanks, encourages rain-water harvesting for both domestic and farm use. Rod Cairns, managing director of JoJo Tanks, believes that a water-secure world is a joint responsibility and that every South African should invest in some sort of system to save water, “We live in a relatively dry country, with an average annual rainfall of about 464mm (compared to a world average of about 860mm). Furthermore, rain tends to be concentrated in certain areas and does not fall consistently throughout the year. These facts, combined with increasing pressures on water resources and infrastructures in South Africa and worldwide, indicate that there may simply not be enough water to meet our future needs and the need to save water will be forced upon us. We need to think of rainwater harvesting as part of a sustainable water strategy.” Cairns explains that Jojo tanks are UV resistant enabling the product to ‘outlive’ some of the harshest South African weather conditions. The company also offers custom moulding solutions, colours and sizes to meet every customer specific requirement. “All JoJo water tanks are lined with a black food safety accredited lining material that inhibits the growth of algae,” concludes Cairns
