Rainwater Storage

Rainwater Storage Increasingly Necessary in Drought-Prone South Africa

While the world’s farmers may choose to rant about the damage caused by termites, locusts and other pests, it is, in fact, humankind that has proved to be the planet’s most destructive lifeform. In the last 200 years of the approximately 200 000 years since the first appearance of Homo sapiens, we have managed to consume or destroy much of that which the evolving planet earth has taken more than 4,5 billion years to perfect. Regardless of the impending consequences of climate change following the rampant burning of fossil fuels, we are now faced with another crisis which, without suitable conservative measures such as rainwater storage, could hasten humanity’s demise even further.

Rainwater storage is essentially a relatively low-tech option and one that is also fairly inexpensive to implement. However, if enough South Africans are prepared to adopt this simple measure, the benefits could be dramatic, especially given that the recent woes of those living at the tip of the Western Cape have opened our eyes to the true gravity of a shortage of potable water.

Of course, the water that is collected and stored in this fashion is unsuitable for drinking purposes without further treatment, and this would obviously add to the cost. However, even with no additional treatment, should we be willing to adopt a culture of rainwater harvesting and storage, this could go a long way towards preserving this vital resource. When used for domestic tasks such as cleaning cars and windows, watering lawns or irrigating an orchard or vegetable garden, consumers can become less dependent on costly municipal supplies, while also relieving some of the pressure on service providers by allowing them to build up some much-needed reserves. On the farm, the benefits are similar, but on a much larger scale.

In South Africa, one name has long been associated with the harvesting of rainwater in storage tanks and that is JoJo. These iconic green tanks, that have been a common sight on farms and smallholdings for more than four decades, are now appearing more frequently in the grounds of private homes, No longer limited to green, these UV- and corrosion-resistant polyethylene vessels now come in a range of colours to match your home’s exterior décor. In addition, they are fitted with a food-grade inner lining that serves to inhibit the growth of algae.

There is a choice of vertical or horizontal tanks, as well as either surface or underground installation and these can be supplied with all of the guttering and piping necessary to transfer the rainwater from your rooftops into the storage tank, as well as a basic pre-filtration system. For those who wish to go the extra mile, a fully integrated system with additional equipment for filtering and sterilisation is designed to supplement the harvested reserves with a pre-determined volume of water drawn from your municipal supply when plentiful. In times of drought and restrictions by the municipality, the treated mix then becomes an emergency cache that is suitable for all domestic use including cooking and drinking.

Whether it is your wish to help conserve our threatened reserves of water, or to combat the regular monthly tariff increases that shortages have prompted, rainwater storage offers a cost-effective solution with which to achieve either goal.
