Sand dams or silt traps?


Erik Nissen-Petersen, ASAL Consultants Ltd. (2011)

It has been known from the African Land Development Project (ALDEV) since the late 1950s, that the spillways of sand dams must be raised in stages not exceeding a height of 50 cm in order for floods to deposit coarse sand from where most water can be extracted. If a spillway is not built in stages, then silt will be deposited instead of sand and very little water, if any, can be extracted from such a sand dam - or is it a silt trap? (source)

l'Eau: des Solutions Simples et Économiques


NWP, NWP (2006)

Cette brochure sur l’eau, comme sa contrepartie ‘Des Solutions intelligentes pour l’assainissement’ (Smart Sanitation Solutions), relate des exemples d’innovations à petite échelle telles que la désinfection solaire de l’eau, l’emploi de filtres à eau efficaces et peu coûteux, le recours à l’irrigation goutte à goutte à bas-coût et l’utilisation de pompes manuelles fabriquées localement et cinq fois moins chères que les pompes importées. En adoptant ces technologies, les foyers défavorisés dans les zones rurales peuvent doubler, voire tripler leur revenu annuel. Les solutions à petite échelle ont montré qu’elles pouvaient être économiquement rentables. Installées en grand nombre, elles peuvent à la fois améliorer la santé publique, relancer la production agricole et générer des activités locales. C’est pourquoi la diffusion à grande échelle de ces technologies est essentielle. (source)

Low-cost methods of rainwater storage; Results from field trials in Ethiopia and Kenya


Kithinji Mutunga, Will Critchley, Sida's Regional Land Management Unit (2002)

Rainwater harvesting is one solution to the problems of water shortage in the drier areas of Africa, but its implementation presents a number of challenges, of which storage is the main one. Many people in rural areas who would like to harvest rainwater lack the resources to do so. Conventional stone, brick or ferrocement tanks are costly, and therefore there is a great need for cheaper alternatives. This publication gives an account of two trials conducted in 1998/99 to investigate some such alternatives. In Ethiopia, five different methods of tank construction were tested in the suburbs of Nazareth town in Adama Woreda. In Kenya, six different methods were tested during the same period at various locations in Machakos and Makueni Districts. A main feature of the alternative tank designs is that they are built underground, which reduces the need for reinforcement materials. (source)

Smart Disinfections Solutions


NWP, NWP (2010)

This booklet aims to help achieve the drinking water targets as stated in Millennium Development Goals 7: halving the proportion of people who don't have sustainable access to safe drinking water and basic sanitation. In 2009 some 884 million people still did not have access to an improved water facility. Experience shows that access to 'improved' water supply facilities is no guarantee for safe and reliable water. Especially in developing countries tap water can be unsafe, because of inadequate treatment, recontamination during transport or storage or at home. 'Point of use' and small-scale treatment is a promising strategy to improve access to safe drinking water, in particular for the poor. Recent studies show that PoU reduces diarrhea morbidity for children under 5 by 29 % and is more effective than source water treatment, piped water on premises and improved public water supply. All the more reason to provide those who advise on systems for home water treatment in rural areas with current information on simple methods to improve drinking water for households. This booklet, part of the Smart Water Solutions series, can help them decide which method is best for a specific situation and what effect can be expected with respect to reduction of harmful micro-organisms. It also gives some price indications and refers to specific websites for further information. This publication is a co-production of NWP (Netherlands Water Partnership), Aqua for All and Witteveen+Bos. (source)

Smart Water Harvesting Solutions


NWP, NWP (2007)

This booklet on Smart Water Harvesting describes a number of creative solutions in situations where ‘there seems to be no water’. It shows practical efforts to ‘create water’, especially in drought prone areas. It does not limit itself to the act of harvesting, but includes ‘capturing’ water during periods of rain, so that it is available for periods of drought. Many of the technologies highlighted in this booklet are traditional, but neglected in the modern world, as people try to become less dependent on the wiles of nature. There is an increasing awareness that rather than fighting against nature, people should co-operate with it. That is what water harvesting tries to do. Like its equivalents on Smart Water and Smart Sanitation, this book gives examples that have proven to be effective and affordable. The book is an effective source of inspiration for local communities, civil engineers, NGOs, research institutes, donors and governments. (source)

Smart Water Solutions (English)


NWP, NWP (2006)

This booklet on water gives examples of innovations such as the use of sunlight to purify water, effective low-cost water filters, low-cost drip irrigation and locally prodcued hand pumps that are five times cheaper than imported pumps. By usiing these technologies, poor rural families can double or even triple their annual income. The book is designed as a source of inspiration, rather than a 'how to' manual. This publication is a collaborative effort by eight organisations: NWP (Netherlans Water Partnership), Practica, Simavi, IRC, Agromisa, NCDO, Aqua for All, Partners for Water. (source)

Technology notes


WaterAid, WaterAid (2007)

These technology notes have been prepared following many general enquiries for technical information having been received by WaterAid over the years. Their purpose is to give an outline of the technologies used by WaterAid on long-term development projects in Africa and Asia, and to show alternatives which might be appropriate in different circumstances. It may be possible to determine from the notes the technology which would be appropriate in a particular location. If it is proposed to proceed with the design and construction of a project using any of the principles set out in these notes, it is strongly recommended that further details be obtained from a specialist or from the reference books which are listed at the end of the relevant section.
