URBAN RAINWATER HARVESTING WITH PRODIST
SOUTH AFRICA’S PRODUCERS HAVE A PROUD REPUTATION AMONG THEIR GLOBAL COLLEAGUES FOR CREATING “MIRACLES” IN FARMING.
Given our rainfall patterns versus yields, our producers know how to apply precision farming as well as every other trick in the book to get the most out of the dry conditions.
The ability to harvest rain during the rainy season is another trick up the sleeve of the producer, which has stood many a farm in good stead during the drier months. And with the rainy season around the corner, Prodist has the complete rain harvesting system to make sure home and farm can save every drop of rain coming its way. As previewed in our November/December issue of 2015, all the components in the diagram are just a phone call away at Prodist.

Rainwater harvesting is a practical, cost effective method of addressing some of our major water challenges in South Africa. The environmental impact of urbanisation has an effect on our water resources and this leads to the demand for rainwater harvesting systems. The benefits of rainwater harvesting are paramount to a sustainable water environment in urban areas and we need to spur on the uptake of these systems by residential, commercial and industrial property owners.
There has been a revival of urban rainwater harvesting in the past few decades as population pressures and increased cycles of drought and flood put strain on our water resources. The high cost of centrally supplied water, in both economic and environmental terms, has driven many people to consider more sustainable methods of water supply. Modern products (such as the ones supplied by Prodist) and system design techniques can ensure a much higher quality of water than traditional low-tech gutter-to-barrel systems. This growing trend has put rainwater harvesting at the centre of the discussion as a cost effective and environmentally friendly solution that all urban inhabitants in South Africa can embrace.
South African domestic water consumers use about 4 trillion litres of water per year. If just 10% of property owners install rainwater harvesting systems and reduce their water consumption by 50%, we could save a staggering 200 billion litres per annum.
The three key elements of a roof harvesting system:
Leaf and debris catcher. Commonly known as a “rain head”, these devices are installed under a gutter or mid-mounted on a rainwater downpipe to prevent leaves and other debris from the roof entering the system. RHAD02/100
First Flush Diverter. Diverts the first flush of rainfall which contains contaminants such as bird droppings or chemical residue from the roof, and ensures that only the cleanest water enters your tank. RHFFDS/100
Insect Proofing. Screens with less that 1mm aperture must be installed at all entry and exit points to prevent vermin, mosquitoes, and other insects from infecting your water supply RHTAT005 / RHMESH / RHSCR480.
