Spring shootThe issue of water pollution is becoming more and more serious – it is starting to poison the vegetables we eat. This, in turn, can poison you. So, even if you don’t care about ‘going green’, it makes sense to start growing at least some of your own vegetables.

The problem, according to water expert and Professor at the University of the Free State’s Centre for Enviromental Management, Anthony Turton, lies with the pollution entering our rivers and dams from dysfunctional sewage treatment plants and informal settlements.

It is Professor Turton’s opinion that 60%+ of the water in South Africa’s dams is no longer suitable for human consumption or irrigation. ‘Water eutrophication’ (resulting in blue/green algae) is creating toxins that are already killing some of the animals that drink such water. In humans, these toxins could enter plants and then into those who have consumed contaminated food.

According to Professor Turton, the Government appeared to be hostile to those scientists who talk about ‘water eutrophication’ and has closed down its eutrophication project.

Grow more of your own veg, using properly treated water or rain water – it will be good for the planet, and good for you and your family.

rainwater harvestingRainwater harvesting can (a) assure an independent water supply during water restrictions, that is though somewhat dependent on end use and maintenance, (b)usually of acceptable quality for household needs and (c) renewable at acceptable volumes despite forecast climate change (CSIRO, 2003). It produces beneficial externalities by reducing peak stormwater run off and processing costs. RH systems are simple to install and operate. Running costs are negligible, and they provide water at the point of consumption.

Rainwater harvesting can be adopted in cities to supplement the city’s other water supplies, to increase soil moisture levels for urban greenery, to raise the water table through artificial recharge, to mitigate urban flooding and to improve the quality of groundwater. In urban areas of the developed world, at a household level, non-potable uses of harvested rainwater include bathroom (i.e. shower/bath/basin), flushing toilets and washing laundry. Indeed in hard water areas it is superior to municipal water for laundry because of its compatibility with detergents and soaps. Rainwater may require treatment prior to use for drinking, depending on anthropogenic (e.g. vehicle exhaust) and natural (e.g. Coal.) contaminants.

In New Zealand, many houses away from the larger towns and cities routinely rely on rainwater collected from roofs as the only source of water for all household activities. This is almost inevitably the case for many holiday homes.

Rainwater harvesting is particularly relevant in areas such as the Garden Route where relatively good rainfall is experienced during summer and winter but due to the towns growing at a rapid rate the dams cannot cope.  Water shortages have become more frequent in many towns and cities around South Africa.

GEORGE NEWS – Nedbank donated a water tank to MM Mateza Primary School last Friday for catching up the rainwater to water the school’s vegetable garden. The initiative forms part of the Earth Child Project.

WESSA’s Corporate Volunteer Programme (CVP) offers volunteers from the corporate sector an opportunity to engage in meaningful and sustainable social and environmental actions that directly address the needs of the schools and the community. Through the CVP, Nedbank has implemented projects such as vegetable garden tunnels, rainwater harvesting tanks and solar cookers in schools throughout South Africa. Teams of volunteers from Nedbank branches work together with school learners and community members to install the projects, generously sponsored by Nedbank. These projects aim to improve certain aspects of environmental management at the school, encourage environmental learning and knowledge building, develop skills, build relationships, and instil a sense of ownership of and pride in the school or community environment.

MORE than two months since being submitted by a councillor, the Nelson Mandela Bay Municipality still cannot answer questions on the planned purchase of rainwater tanks for low-income houses without roof guttering.

Acting municipal manager Elias Ntoba told the council last Thursday he had still not received answers to questions put by DA councillor Gustav Rautenbach.

Speaker Helen Sauls-August said the replies must be sent to him in writing within seven days.

An angry Rautenbach said the questions were submitted more than two months ago and it was “unacceptable” that they were still unanswered.

The Herald revealed earlier this year the city planned to buy 1000 rainwater tanks for RDP houses without guttering, saying the water would be collected for domestic use. It was also revealed the city planned to fork out R7500 as part of a “rainwater harvesting” initiative for the 5000-litre tanks, which can be bought online for as little as R2700 and probably less in bulk.

In a memo to executive directors at the time, strategic planning and integration sub-directorate head Sithembele Vatala said the city intended “to implement the piloting of the 1000 units for the RDP houses with immediate effect”.

It had the “institution’s support” and Ntoba was “awaiting a report”.

In the memo, Vatala said the water crisis “calls for desperate measures”. The project would “revisit the old practice of rainwater harvesting in South Africa against the backdrop that the country is water- scarce, with a history of huge inequities in the distribution of both land and water resources, coupled with the fact that the country is fast reaching the limits of what is achievable from a conventional water supply-oriented approach to meeting ever growing demand”.

In addition to being cheap, it could “contribute to improved health”.
