Technology Transfer for Development: Insights from the Introduction of Low Cost Water Well Drilling Technology to Uganda

Downloads:


Author: DANERT, K.
Year of Publishing: 2003
Publisher:
Institution: Cranfield University

Third World development theory and practice are changing so rapidly that it is important to critically examine the fashions of today before they become history. This thesis considers the development, transfer, early adoption and sustainable use of technology, coupled with private sector participation in rural water supply provision.

Improving water supplies for rural communities is one of the key challenges faced by development interventionists today. Lack of low cost, off the shelf technology for local enterprise which can provide affordable shallow wells for rural communities is one barrier to facilitating improvements.

This thesis is based on research undertaken in Uganda to develop and transfer low cost water drilling technology in the context of decentralisation and privatisation policies. An extensive range of literature has been drawn together into 16 principles which guide technology transfer and development intervention. These principles are reexamined in the light of analysis of first hand experiences of undertaking a technology transfer project and interviews with stakeholders regarding their attitudes and perceptions.

Upgraded Family Wells in Zimbabwe Household Level Water Supplies for Multiple Uses

Downloads:


Author: ROBINSON, O.
Year of Publishing: 2002
Publisher: WSP/World Bank
Institution:

Most drinking-water programmes of governments, NGOs and external support agencies concentrate on public supplies, for domestic purposes only. In Zimbabwe, however, the long-established upgraded family well (UFW) programme has two particularly interesting features. Each household invests in and manages its own water supply without depending on the government for maintenance; the same water source is often used for both domestic and productive purposes, which can considerably increase the incomes of poor people.

Draft Review of the Household Arsenic Removal Technology Options

Author: MUDGAL, A. K.
Year of Publishing: 2002
Publisher: RWSN
Institution: Handpump Technology Network

Arsenic is widely distributed element in the earth’s crust and ranks twentieth in elemental presence. As a Group V element, arsenic exhibits a broad range of chemical reactivity and it is commercially used in alloys with lead. Arsenic in natural water has been reported from several countries including Bangladesh, China, Chile, Ghana, India, Nepal, Rumania, Taiwan, USA and Vietnam. In India, arsenic pollution is mostly of geological origin. However, ground water pollution of anthropogenic origin - due to industrial or mining waste - has been reported from Chennai in Tamil Nadu and Rajnandgaon in Madhya Pradesh.

Designing Water and Sanitation Projects to Meet Demand in Rural and Peri-urban Communities Book 1, Concepts, Principles and Practice

Downloads:


Author: Deveroll P., Bibby S, Wedgwood A, and Smout I.
Year of Publishing: 2002
Publisher: Loughborough University
Institution: WEDC

This book is divided into two parts. Part 1 looks at all aspects of ‘demand’ for a service. Demand is assessed in several ways and affected by many external factors. Some factors will affect the options which are available to the users, such as ability to pay for a service. These issues are discussed in detail in Part 1. Part 2 of the book is concerned with ‘practice’. It offers guidance to practitioners with respect to ‘demand’ to enable them to: develop a project strategy; identify peoples in risk of exclusion; prioritise communities’ activities; appraise a community plan; develop a range of service options; support local management to ensure sustainability.
As a guidance document it is a valuable resource for project planners. It provides detailed help, along with case study examples, of what factors need to be considered from the very beginning of a project.

Groundwater Quality Protection A guide for water utilities, muncipal authorities, and environment agencies

Downloads:


Author: FOSTER, S., HIRATA, R., GOMES, D., D'ELIA, M. and PARIS, M.
Year of Publishing: 2002
Publisher: The World Bank
Institution: GW-MATE

This publication provides guidance to water-sector decision makers and planners on how to deal with the quality dimension of groundwater resources management in the World Bank's client countries. There is growing evidence of increasing pollution threats to groundwater and some well-documented cases of irreversible damage to important aquifers. This guide has been produced in the belief that groundwater pollution hazard assessment must become an essential part of environmental best practice for water supply utilities. The guide is particularly relevant for the World Bank's Latin American and Caribbean Region, where many countries have initiated major changes to modernize their institutional and legal framework for water resources management, but may not yet have considered groundwater at the same level as surface water, because of lack of awareness and knowledge of groundwater issues and policy options.
