Green rainwater harvesting contains a series of blogs printed in the Witness, a regional newspaper from the Midlands in South Africa.
Harvesting rainwater is not rocket science; we have found that storing it in an underground reservoir is the best way. It is a concept first learned from the Dutch whilst living in the Netherlands. Reticulation came fairly late to many of the older parts of the country where the masters of water management live. We can learn from them.
Underground the water is much colder and thus less prone to the proliferation of bacteria. It is also cheaper than above ground plastic or fibreglass tanks, and far less unsightly.
Green rainwater harvesting turned out to be a relatively inexpensive project. It is certainly cost-effective; our is long paid off giving us an almost unlimited supply of the pristine manna that falls from the heavens. It is all part of our determination to make our home resilient on the one hand, and do our small bit to preserve the planet on the other.
The first step was to dig a hole; four strong men did it by hand in three days.
Then the semi-skilled men moved in, laying a reinforced concrete foundation and bricking up the double wall. Plastering was the only tricky part; a sealing compound should be included in the mix.
Next was the roof, connecting the pump into the reticulation to our green home and garden; and an electrical supply.
This is what we are now calling the real Preston, a spoof on the self-oiler designed by McCoy for his steam engines.
How safe is our drinking water is a question we should all be weighing, without becoming neurotic. Are there alternatives? The average person in the Western world consumes about 5 grams of plastic every week, most of it from our drinking water; that is the weight of a credit card.
Where is our water is a cry that reverberates around South Africa; the provision of water is failing weekly in every part, whether because of drought, or incompetent municipalities that do not repair and maintain the reticulation. It behooves each of us to practise green rainwater harvesting.

Here are the back issues.
Southern African scientists are now agreed that the death of 330 elephants in Botswana was caused by a neurotoxin produced by the cyanobacteria that flourish in warm water. This same bug flourish in at least half of South Africa's dams. Runoff from fertiliser and sewerage plants that produce large amounts of phosphorus have been fingered. It is not unlike botulism in many respects.
Reports state that it is difficult to make the contaminated water potable; it is just one more reason to consider green rainwater harvesting. It saves money, tastes far better, will not have poisonous byproducts from post-chlorination or the cyanobacterium toxin, and contributes to saving the planet; can we ask for more?
