Comprehensive water management

Water and the lack thereof have been cited by water experts to be at least as big a problem as climate change in the twenty first century. About 2 billion people around the world either lack access to sufficient quantities of water or are supplied with water unfit for drinking and this shortage is going to worsen in the near future due to the rise of the world’s population and to the redistribution of water recourses due to global warming.

According to UBS underinvestment in water infrastructure has resulted in great inefficiencies and cities like London and Shanghai are wasting more than 60% of their water supply due to something as simple to fix as leaky pipes.

Globally, UN reports put the loss of drinking water before it reaches the consumer at 33%. The total cost of ‘non revenue water’ is conservatively estimated at $14,6bn per year. One of the first companies geared to comprehensively address this is Israeli company Miya.

Miya is the first global player to offer a comprehensive water efficiency solution and a one stop shop for water loss projects. Their mission is to help the cities of the world benefit from the huge opportunity presented by water loss reduction and effective management of urban water. Their products and services include pressure management, leak detection, filters, pumps and measurement tools.

The benefits of their solutions for Water Loss Management are:
• Produce /purchase less water
• Energy savings due to improved efficiency of the system
• Reducing the amount of chemicals used to treat the water
• Saving or postponing investments in increasing water capacity or developing alternative water sources
• Extending the lifespan of existing infrastructures
• Reducing maintenance cost
• Increase revenues by reducing commercial losses caused by lack of metering and/or poor metering and billing policies.
• Lower contamination risks to the water supply from bursts and antiquated pipes

World’s largest solar project planned in Sahara

If just 0.3% of the Saharan Desert was used for a concentrating solar plant, it would produce enough power to provide all of Europe with clean renewable energy. That is why 20 blue chip German companies are gathering in July 2009 to discuss plans and investments to create such a massive project. Both the meeting and project are being promoted by the Desertec Foundation, which is proposing to erect 100 GW of concentrating solar power plants throughout Northern Africa.

The red squares in the map to the right represent the land area necessary to meet the energy demand of the world, the EU and MENA in 2005. The last square represents the land necessary for the proposed project to generate 100 GW of concentrating solar power. The project being proposed by Desertec would not all be situated in one location, but scattered throughout politically stable countries. Taken as a whole, the project qualifies as the world’s largest solar installation – 80 times larger than the PG&E and BrightSource project planned for the Mojave Desert. The power generated would be transported over high-voltage DC lines across the Mediterranean Sea to Europe, where it would supply 15% of the energy demand. The project is still 10-15 years from going online, but that’s why major players are getting started now.

Wine industry embraces sustainable development

Clean vineyards, ‘green’ wines and lighter bottles? Many in the global wine and spirits business believe their only chance of long-term survival lies with sustainable development.

“Within five years, there will be a global standard of sustainability and a level below which you cannot be,” said Robert Joseph, a London-based writer and wine producer. Joseph and his partners at Hugh, Kevin & Robert Wines, have launched a new line called ‘Greener Planet Sustainable’, which is a low carbon footprint wine. One of these, retailing at roughly $10 and packaged in a lighter plastic PET bottle, has been snapped up by importers for Norway and Holland.

Sustainable development, independent of organic or biodynamic production, was very prominent at the recent Bordeaux Vinexpo, the largest wine trade show in the world. Val d’Orieu, a wine cooperative whose members’ vineyards stretch over 9 000 hectares along the French Mediterranean, even rethought its stand at Vinexpo. The cooperative ordered an ecologically designed exhibit stand, including re-useable glass and wood panels, rented furniture, and eco-friendly paint. According to the stand creator, it was the first such order they had ever received.

PlayPumps – a proudly South African invention

PlayPumps International’s mission is help improve the lives of children and their families by providing easy access to clean drinking water, enhancing public health, and offering play equipment to millions across Africa. It is an South African invention that was developed into one of the most innovative water solutions for poor families around the world.

In essence it is a children’s merry-go-round attached to a water pump, with a connected high capacity storage tank and tap.

The recipient of several international innovation awards, by 2010 the organisation plans to have 4000 PlayPump systems installed that will supply water to about 10 million people. The organisation’s funding model is also innovative. They seek donations for the installation of the system, and then sell advertising space on the water tower to pay for the maintenance of the system.

The design of the PlayPump water system makes it highly effective, easy to operate and very economical, keeping costs and maintenance to an absolute minimum. Capable of producing up to 1,400 liters of water per hour at 16 rpm from a depth of 40 meters, it is effective up to a depth of 100 meters.

Basically, the system works as follows: While children have fun spinning on the PlayPump merry-go-round (1), clean water is pumped (2) from underground (3) into a 2,500-liter tank (4), standing seven meters above the ground.
A simple tap (5) makes it easy for adults and children to draw water. Excess water is diverted from the storage tank back down into the borehole (6).
The water storage tank (7) provides a rare opportunity to advertise in outlaying communities. All four sides of the tank are leased as billboards, with two sides for consumer advertising and the other two sides for health and educational messages. The revenue generated by this unique model pays for pump maintenance
