Huge dams have been touted as effective in providing drinking and irrigation water, all cheaply and sustainably. Recent studies reveal otherwise as most of these projects in sub-Sahara turn out to be more costly than planned. A recent study has quantified claims that large dams also lead to more malaria being spread in the sub-Saharan, thus adding more weight to concerns on whether these projects should be pursued actively in favor of the alternatives.
Solar power is about more than lighting your home… Regular access to hot water for bathing, cooking, and cleaning is something that most of us in the Western world take for granted. However, people in rural communities throughout the world struggle to safely and economically heat their water on a regular basis. Solar hot water systems offer a sustainable and low cost solution to this widespread issue, with the potential to bring hot water to those who do not currently have it.
ADI Systems has been specializing in the design and construction of industrial wastewater treatment systems for over 30 years. Berni Chapman is a wastewater treatment specialist with ADI Systems, who has extensive experience in waste-to-energy projects particularly in the food industry, everything from initial laboratory and pilot scale testing through to detailed design. Angela McClowry from Cleanleap recently interviewed Berni to discuss wastewater treatment in emerging economies.
Long Sokhon is a small-scale farmer in Cambodia’s Pursat Province. Like 85% of Cambodians, she makes a modest living off the land. She used to cook for her family of eight over a wood-chip fire by night. Sokhon lived the way most do in rural Cambodia—one of the poorest countries in South East Asia with a population of 15.8 million. Then, she was given the opportunity to have a 2,000 litre slate-grey tank installed in the vegetable patch. Long Sokhon was chosen as part of a biodigester pilot project run by Engineers Without Borders Australia and Live & Learn Environmental Education.
Nick Boerema is the Facilitator for Engineers Without Border’s Sanitation in Challenging Environments project and is based in Phnom Penh, Cambodia. Nick’s role includes providing technical advice on sanitation solutions and facilitating collaborative efforts to promote knowledge dissemination, innovation and adoption of best practice for sanitation in challenging environments. Nick previously worked in Australia as a project engineer for Vast Solar, managing the development and demonstration of low-cost concentrating solar thermal technology for power generation. Cleanleap's Angela McClowry recently interviewed Nick to better understand some of the challenges in sanitation and ways in which we can 'cleanleap' over existing issues.
A local entreprenuer in Tanzania has devised a solution that seeks to eliminate all the problems associated with unsafe/unclean water and sanitation. It will help locals avoid related diseases. What's more is that his solution is low-cost and requires no power compared to other water treatment technologies. It is also made from local materials, recyclable, and versatile in that it can be tailored to treat water in vartually any location/area. The nano-filter combines nano-filtration technologies with sand-based water filtration techniques. It has already been rolled out in the market and is gaining ground.
The construction of the Grand Ethiopian Renaissance Dam (GERD) resonates of nothing but patriotism and deep commitment of Ethiopians towards achieving clean energy for their country. Since the inception of the dam in 2010, there have been a number of issues but the project is now moving ahead at full steam.
Sanitation and water treatment in the developing world is set to change with the onset of the Omni Processor. The Bill Gates and Melinda Gates Foundation have decided to invest in a machine that turns sewage into drinking water and can also generate energy. Just as importantly it is relatively low-cost, making it a technology that can be rolled out quickly in emerging economies.
Tony Weber is an Associate at BMT WBM with over 25 years experience in the water industry. In his role, Tony has focussed on improving the management of stormwater, river basins and environmental management across the world, with a particular focus on the UK, Australia and China. Lindsey Beck recently interviewed Tony for Cleanleap to get his perspective on water’s role in a developing country’s journey to sustainability.
Water is one of the great human challenges of our time. As an essential resource for human life, it is staggering that so much of the world should exist without the basic potable water and sanitation services that we know in the developed world. Making a Cleanleap in urban water management practices could facilitate greater access to water for millions of existing city dwellers in developing countries.
