SADC Water Dialogue opens up new channels

The 7th SADC Multi-stakeholder Water Dialogue recently was held in Windhoek, Namibia from 29-30 September 2015.
Theo Diergaarat, Namibia’s deputy minister for agriculture, water and forestry, called the SADC roadmap and strategy for the region a major milestone which will accelerate economic growth in the region, and also diversify and broaden the manufacturing and industrial bases.
The stakeholder dialogue is a joint organisational collaboration between the SADC Secretariat and the Global Water Partnership Southern Africa (GWP-SA), operating under the theme of ‘Watering development in SADC: The central role of water in driving industrialisation’.
“Water cuts across all sectors of our economy and is not a one-man business as it requires all sectors to work together in a nexus approach. We acknowledge the efforts made by GWP-SA together with the SADC Secretariat’s water division who singled out Namibia to be the host for the water dialogue,” Diergaarat said.
Assistance for the conference has also been received from the Desert Research Foundation of Namibia, which acted as the secretariat for Namibia Water Partnership, and support staff from the Namibian Agriculture Ministry, according to Diergaarat.
Diergaarat added that Namibia, like most African water-scarce countries, is looking to take advantage of cooperation in international shared water resources in order to maximise the benefits for industrial development.
The multi-stakeholder water dialogue is a bi-annual activity which originated through the Integrated Water Resources Management awareness creation programme. – Africanfarming.net



Rain water harvesting for farmers

South Africa is a particularly water scarce country, leaving it in a perilous position when met by drought like in recent months. A viable solution to help save water and aid dams the opportunity to refill themselves and recover, is through rain water harvesting.
Water tanks are self-sufficient and made to work with the environment. Rainwater tanks are a fundamental invention and have been used for many years. In today’s times, water tanks continue to benefit farmers and various other industries as well as for domestic use. According to many a research study, rainwater has proven to be naturally clean and chemical free. In the instance of farmers, water for irrigation is a luxury in times of drought and in traditionally dry areas. By saving and storing water during the rainy season one can provide much needed irrigation for land when the seasons change.
South African based Roto Tank produces polyethylene tanks which are ideal for rainwater harvesting. According to the company these polyethylene tanks are lighter than the stainless steel alternative, making them easier to transport and unaffected by corrosion and rust, which may render water unusable in certain circumstances.
Furthermore, Roto Tank has introduced a combination of water tanks and troughs for efficiency. Water troughs, have a variety of uses on the farm and can work in conjunction with water tanks for optimum results. Says Roto Tank: “Many farmers make use of rainwater harvesting methods in order to save on water expenses. Water collects into various water tanks during rainfall. Farms in general consist of hectares of land and farmers harvest water by making use of water tanks fitted to a trough at the bottom tank that will allow water to be available for animals to drink. Some of our troughs can hold more than 800 litres of water at a time. Moreover water can also be treated with nutrients and medication and used in a livestock water trough. Various animals can drink from the trough including horses and ostrich.
The ball valves present in the water tank and trough will ensure that water levels remain constant. The ball valves are tamper proof and secure from any potential damage caused by livestock.”
Jojo Tanks, a world renowned manufacturer of water tanks, encourages rain-water harvesting for both domestic and farm use. Rod Cairns, managing director of JoJo Tanks, believes that a water-secure world is a joint responsibility and that every South African should invest in some sort of system to save water, “We live in a relatively dry country, with an average annual rainfall of about 464mm (compared to a world average of about 860mm). Furthermore, rain tends to be concentrated in certain areas and does not fall consistently throughout the year. These facts, combined with increasing pressures on water resources and infrastructures in South Africa and worldwide, indicate that there may simply not be enough water to meet our future needs and the need to save water will be forced upon us. We need to think of rainwater harvesting as part of a sustainable water strategy.” Cairns explains that Jojo tanks are UV resistant enabling the product to ‘outlive’ some of the harshest South African weather conditions. The company also offers custom moulding solutions, colours and sizes to meet every customer specific requirement. “All JoJo water tanks are lined with a black food safety accredited lining material that inhibits the growth of algae,” concludes Cairns

Drip irrigation advances

Irrigation is the controlled application of water for agricultural purposes through manmade systems to supply water requirements not satisfied by rainfall.



A solution to collecting and storing water in countries that have a lack of adequate access to clean water retailers

The 2014 Global Risk Report conducted by the World Economic Forum rated “water crises” as the third most significant global risk.
It is estimated that water usage will have grown to 2.7 billion cubic metres globally by 2030. This will leave a 17% gap between supply and demand for the resource.
According to water.org, there are 750 million people around the world who lack access to safe water. This is approximately every one in nine people.
“Diarrhoea caused by inadequate drinking water, sanitation, and hand hygiene kills an estimated 842,000 people every year globally, or approximately 2,300 people per day,” world.org states.
82% of those who lack access to improved water live in rural areas, while just 18% live in urban areas.
Grant Gibbs, executive director at the Hippo Water Roller project asks: “Why should millions of women and children struggle just to get water to their homes every single day?”
Despite many interventions, the scale of the problem of lack of access to safe water is likely to increase in the coming years.
When asked about what the daily struggles in Africa are related to the lack of adequate access to clean water, Gibbs says: “It is mostly women and children who are forced to fetch and carry water to their homes. Water points are often far away and it is time consuming to collect water, and requires multiple trips per day.”
He describes one solution: a barrelshaped rolling container that is designed to transport 90 litres (24 gallons) of water at one time.
This way of gathering and storing water is used in various parts of Africa – namely, South Africa, Angola, Botswana, Burkina Faso, Congo, Democratic Republic of Congo, Gabon, Ghana, Kenya, Lesotho,
Madagascar, Malawi, Mozambique, Namibia, Somalia, South Sudan, Swaziland, Tanzania, Uganda, Zambia and Zimbabwe.
The Hippo Water Roller was designed to alleviate the suffering caused by a lack of access to water. Its design allows water to be placed inside the “wheel”, resulting in an effective weight of just 10kg (22
pounds) on level ground. More water can be collected in much less time and with far less effort, transforming water collection from a daily chore to a task performed only a few times a week.
The Hippo Water Roller consists of a round plastic drum made from polyethylene which has a long molecular
structure for flexibility while rolling along uneven and rough surfaces.
The wall thickness is sufficient to prevent puncturing and cracking. There is a large opening and screw-cap to facilitate easy cleaning of the interior, yet small enough to prevent small children and babies from drowning. The U-shaped steel handle has simple “bearings” to protect the drum recesses from wear and tear where the handle clips on and off the drum. This design allows the operator to simply push or pull the drum while the weight of water goes into the ground, requiring less effort than carrying a
bucket on the head.
The design was invented in 1991. It received a design award from the SABS Design Institute in 1992 and was initially called the “Aqua Roller”. The name was changed to the Hippo Water Roller to give it a more African resonance.
The name stems from its thick skin, round body and because it lives in water. It was designed by South Africans Pettie Petzer and Johan Jonker, both engineers who had grown up on farms.
Searching for a design to allow rural communities to carry water more easily, they initially tried to design a wheelbarrow incorporating a moulded tank with a low centre of gravity. When they did the costing, they found the wheel to be the most expensive component. But that was when they got the idea to put the water in the wheel.
Gibbs describes the social impact: “It reduces suffering, improves hygiene and health, enables for more time to be spent being educated and empowers women and children.”
Gibbs says the design is unique and the containers are built to last in rural conditions.
The Hippo storage container is designed to last up to seven years. Gibbs explains that once the container has been damaged beyond its usefulness for collecting water, it can be used as a storage bin. By cutting it vertically in half, “It can also be used as a feeding or watering trough for animals and a bath for washing clothes and children.”
The purposes of the Hippo water roller utility cap as a farmer’s irrigation tool • The utility cap was specifically designed for irrigating crops.
• It allows smallholder farmers to transport 90 litres of water at a time and irrigate crops efficiently.
• Convenient dispensing of water through the mini-cap.
• Mini-cap is a standard soda bottle top for easy replacement if damaged.
• No need to unclip the handle.
• No need to stand the drum upright to access the water.
How to use this system:
• Fill the Hippo Water Roller with water and roll up to the trees or vegetables.
• Simply line up the cap with the trees or vegetable rows.
• Unscrew the mini-cap and allow water to flow out.
• Close the mini cap when sufficient water has been dispensed.
