General information on water harvesting

Rainwater Harvesting in Arid and Semi-Arid Zones
Th.M. Boers, ILRI (1994)

The publication describes a procedure for the design of micro-catchments in sem-arid areas. (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)

Water Surveys and Designs
Erik Nissen-Petersen, DANIDA (2006)

Explains survey techniques and gives standard designs with average costs on water supply structures (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)

Water for Rural Communities
Erik Nissen-Petersen, Birgit Madsen, Munguti Katui-Katua, DANIDA (2006)

How Kenyan rural communities can create their own water supplies with assistance from the Water Services Trust Fund (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.

Introductory Guide to Appropriate Solutions for Water and Sanitation

A planning handbook that provides planners with practical tips on how rainwater harvesting can form an integrated part of district development efforts. The book also gives practical guidelines in the planning steps required to incorporate rainwater harvesting in development plans, and shows how to implement them in the farmers’ context. (source)

Water harvesting; A Manual for the Design and Construction of Water Harvesting Schemes for Plant Production

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)

Water from Dry Riverbeds
Erik Nissen-Petersen, DANIDA (2006)

How dry and sandy riverbeds can be turned into water sources by hand-dug wells, subsurface dams, weirs and sand dams (source)

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)

A study to upscaling of the principle and sediment transport processes behind sand storage dams, Kitui District, Kenya

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)
