Despite all the efforts to date to improve access to safe domestic water supply and sanitation in less developed countries, still between 1 and 3 billion people lack these essential services. The causes of this situation are complex, and are not to be resolved through technology alone. However, it is widely accepted that two broad sets of conditions (among others) need to be in place in order for the situation to improve – technologies which are affordable and manageable by user communities, and the institutional arrangements by which communities can gain access to such technologies.
This document is one contribution from one project in one country (Uganda) within which an attempt is under way to address these issues.

Tanzania Supply Chain Study Report

Institution: Skat

Tanzania is entering a transition period; the rural water policy calls for decentralisation with legal ownership of RWSS facilities by communities, and for the private sector to become a major stakeholder. The institutional framework is favourable, but the decentralisation policy is new, and district institutions lack capacity and experience. Building capacity in the districts and the private sector is needed to allow all partners to assume their new roles. The Learning and Innovation Loan serves as a learning ground to investigate how to gradually change the government‟s role to that of a facilitator and to integrate private sector suppliers for the provision of goods and services.

Report on The Performance of Afridev and Nira Handpumps on the Upper Regions Community Water Project (COWAP) Ghana Report for the GWSC/CIDA Community Water Project Upper Regions, Ghana

Between 1974 and 1981, approximately 2700 boreholes were constructed and installed with handpumps in what was at the time the Upper Region of Ghana, under bilateral agreements between the governments of Ghana and Canada (the Canadian International Development Agency). The handpumps installed during this period were the Moyno and Monarch pumps, which, while robust, required heavier tools and equipment and some specialized skills to maintain. Management and maintenance of these sites was under a centralized system, whereby communities paid a tariff to the national water agency then responsible (the then Ghana Water and Sewerage Company), which fielded repair technicians to perform the work. Problems of long waiting times for repairs were very common due to repair team logistical problems, lack of equipment and shortages of spares.

The Zimbabwe Bush Pump: Mechanics of a Fluid Technology Social Studies of Science

Author: DE LAET, M. & MOL, A.
Year of Publishing: 2000
Publisher: SSS and SAGE Publications
Institution:

In this paper we investigate the intricacies of an admirable water pumping device – the Zimbabwe Bush Pump ‘B’ type – so as to find out what makes it an ‘appropriate technology’. This turns out to be what we call the ‘fluidity’ of the pump (of its boundaries, or of its working order, and of its maker). We find that in travelling to intractable places, an object that isn’t too rigorously bounded, that doesn’t impose itself but tries to serve, that is adaptable, flexible and responsive – in short, a fluid object – may well prove to be stronger than one which is firm. By analyzing the success and failure of this device, its agency and the way in which it shapes new configurations in the Zimbabwean socio-technical landscape, we partake in the current move in science and technology studies to transform what it means to be an actor. And by mobilizing the term love for articulating our relation to the Bush Pump, we try to contribute to shaping novel ways of ‘doing’ normativity.

Hand Sludging - A Report From North West Bengal Report of DFID KAR Project R7126 “Private Sector Participation in Low Cost Water Well Drilling”,

Year of Publishing: 1999
Publisher: Cranfield University
Institution: Silsoe College

The Low Cost Drilling Project (Cranfield University/DFID/Government of Uganda) is developing a modification of the traditional Asian sludging technology for use in Africa.
As part of the technology research a visit was made to north India to observe and measure various characteristics of this well drilling technique. The report describes these observations and draws conclusions for the Low Cost Well Drilling Project.
The method and equipment used by the Indian drillers (“mistries”) are set out, followed by an outline of the ergonomics and quantification of the work rates needed for hole cleaning and drilling. Drilling penetration rates in soft alluvium were observed to range from 16.5 to 45m per hour.
Traditional and more modern designs of casing and wellscreen, and the corresponding well completion methods, are described.
The cost of a 12m water well drilled by sludging in North West Bengal is estimated at Rs200 (approximately £3-4).
Practical conclusions are drawn in relation to equipment design for Uganda or elsewhere in sub-Saharan Africa.

VLOM Pumps Technical Brief 41

Institution: WEDC

A VLOM pump is one which can be operated and sustained using Village Level Operation and Maintenance.
The term VLOM is also used, meaning Village Level Operation and Management of Maintenance.
This addition emphasizes the role of users as the managers of maintenance – they may choose to use someone from outside the village to assist with more complicated repairs. Not all maintenance and repair needs to be done by the villagers for a pump to be classed as a VLOM pump.

The purpose of this study is to review the literature on the experience with an approach to rural water supply known as Village Level Operation and Maintenance Management (VLOM). The following issues are addressed:
· How useful has the concept of VLOM proved to be?
· What evidence is there of success in achieving the objectives of the VLOM approach?
· Has VLOM been incorporated into later concepts such as “community management” of rural water supply?

Despite amazing reports of success and excellent records in the water policy of Zimbabwe, the Bush Pump never had such a reputation when installed outside of Zimbabwe.

This phenomena was the reason of the Skat/HTN mission in June 1997, to have a close look at this pump and to find out what had made this pump so popular in this country for more than sixty years.

Handpump Technology Input to the Joint Review of the Rural Water Supply and Sanitation Eastern Uganda Project- RUWASA Phase IIA

Institution: Handpump Technology Network/Skat

The RUWASA project decided in 1992 to replace all GI rising main and rods with SS materials and to start a monitoring programme on 12 selected wells to check the performance of the SS pipes and rods. The September 1997 report concluded that the SS components showed signs of corrosion and that the watertank and the endcap of the cylinder showed extensive corrosion.
An extended study was carried out in 1998, which revealed that 42% of the 124 wells showed pitting or crevice corrosion of the rising main pipes. Danida asked HTN to:
* assess the performance of the U3 handpumps
* recommend changes in the technology choice for Project Phase IIB
* propose strategies how the material in stock can best be utilised

This report presents the experience from the World Bank-executed UNDPINTIS1/026 Handpumps Project, which analyzed groundwater quality and handpump corrosion in the West African subregion. First of all this report provides an overview of groundwater quality and its physico-chemical composition within the subregion comprising the following countries: Burkina Faso, Cote d'Ivoire, Ghana, Mali, and Niger. This information can be of interest to thse sectors using or depending on groundwater, such as urban and rural water supply, agriculture, industry, and so forth. Additionally, this report covers subjects particularly related to the rural water supply sub-sector, such as the relationships between groundwater quality and user acceptance, groundwater pollution in the rural environment, variations of the physico-chemical composition of groundwater due to natural and anthropogenic effects, as well as some indications of groundwater quality as related to bacteriology.
