Sand Dams: a Practical Guide


Simon Maddrell and Ian Neal, Excellent Development (2012)

This manual describes the process of siting, design, construction and management of sand dams. It is aimed at technical and programme management staff working in arid and semi-arid lands who are interested in trialling the application of sand dams in new areas. The manual draws upon the experience of constructing sand dams in Kenya, where the majority of the world’s sand dams are located. Its primary purpose is to capture this experience. (source)

Construction of wire-reinforced cement mortar tanks


Neil Herath, Comminity Water Supply & Sanitation Project (CWSSP), Ministry of Housing, Construction & Public Utilities, Sri Lanka (1995)

this document has been scanned from earlier manuals and standardizations prepared by Neil Herath for CWSSP – Sri Lanka ( April 1995), and as Manual 3 of the Technical Manual Series on Rural Water Supply and Sanitation, Gravity Water Supply Systems: design and construction (January 2005). It is redesigned to look like the 2005 CWSSP manual guiding field work on wirereinforced cement mortar tanks, commonly known as ferrocement tanks (Han Heijnen, October 2010) (source)

Hydrology of Sand Storage Dams - A case study in the Kiindu catchment, Kitui District, Kenya


Lucas Borst, Sander de Haas, VU (2006)

This report reflects the results of a research project concerning the hydrology around sand storage dams. The Kitui district is one of the arid and semi-arid lands of Kenya. For (drinking)water most people heavily rely on water supply from the riverbeds of ephemeral rivers. SASOL is a local NGO which builds so called sand storage dams in ephemeral rivers to increase the water availability during the dry season. Sand storage dams are small (generally a few meters high) dams built in the riverbed behind which sand accumulates, enlarging the natural aquifer. The groundwater in the riverbed is obstructed by the dam and retained between the pores in the sand, making it available for people and animals during the dry season. (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 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)

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.

Water from sand rivers; A manual on site survey, design, construction and maintenance of seven types of water structures in riverbeds


Erik Nissen-Petersen, Sida's Regional Land Management Unit (2000)

Sand rivers, also called dry riverbeds, transport rainwater run-off from highlands to the sea through the most dry parts of this planet where water is very scarce. Although flood water may be drawn from the sand in some riverbeds for a short period of time after floods, the big majority of sand rivers are dry throughout the years. This book explains in simple terms how dry riverbeds can be changed into water sources for long periods after floods - and in some cases throughout the years. The usual problems of contamination and evaporation in hot climates are almost eliminated due the water being trapped and stored underground between the sand particles of riverbeds. This book is based on the author’s practical experience on developing affordable water supply systems in some of the driest parts of Africa and Asia over the last 25 years. (source)
