Rainwater harvesting

Water is arguably one of the most precious resources on the planet and is in short supply, rainwater harvesting provides a solution to this. With an ever increasing population and the continuous misuse of our water resources we need to preserve as much of this limited resource as we can.

Thousands of litres of rainwater go to waste each and every time it rains. Rainwater harvesting is an easy, effective and affordable way for individual home owners to take advantage of this free supply of water. It involves collecting rainwater that falls onto a roof surface and storing it in a water tank to be utilized at a later time. This is done by means of diverting a gutter downpipe into the top of a rainwater tank. Harvested rainwater is ideal for watering the garden, topping up swimming pools and ponds and washing cars and boats. Rainwater can even be plumbed into a house for flushing of toilets and with extra filtration, washing clothes, showering and even drinking.

Rainwater Harvesting

Rainwater tanks come in a variety of sizes, shapes and colours. Urban rainwater tanks or “under eave tanks” have been designed for residential properties, reducing the size of the area required for a water tank. These urban tanks are much more aesthetically pleasing than conventional tanks making them ideal for model urban living. There are a number of accessories available for rainwater tanks ranging from pre-filtration units (to remove leaves and other debris that is washed off of the roof surface) to water level indicators, pumps and 3 stage filtration units for internal use.

South Africa has an annual rainfall of roughly 450mm of rain. Although this is lower than the world average, it does present a great opportunity to harvest this free resource. Rainwater harvesting not only reduces your monthly municipal water consumption it also helps to preserve this scarce and precious resource that truly is “blue gold”.
