Institution: Skat

This manual provides detailed specifications and design drawings for the AFRIDEV handpump. The AFRIDEV Deep-well handpump is designed to lift water from depths of 10m to 45m. The AFRIDEV is suitable for boreholes with casing sizes of nominal 100mm, 115mm, 127mm or 150mm internal diameter (4", 4.5", 5" and 6").

The Specification results from work carried out by the UNDP-World Bank Water and Sanitation Program in partnership with handpump fieldworkers and development organisations in many countries.

Since the issue of the first AFRIDEV Specification in 1989, the AFRIDEV has become the deepwell VLOM handpump of choice in an increasing number of countries in Africa and Asia.

Manual Drilling Compendium 2015 RWSN Publication 2015-2

Manual drilling refers to several drilling methods that rely on human energy to construct a borehole and complete a water supply. The various techniques can be used in areas where formations are quite soft and groundwater is relatively shallow.

Manual drilling can provide safe drinking water. The equipment can easily be transported to remote, or difficult to serve populations which would otherwise be left behind. The lower costs compared to machine drilling are appreciated by households, businesses and governments. Manual drilling also provides local employment.

Manual drilling methods are being used to provide water for drinking and other domestic needs at least 36 countries around the world. In some places, manual drilling methods are well established.

The compendium provides a useful overview for those wishing to further examine the impacts and challenges of manual drilling, and, more importantly, improve practices on the ground. It is hoped that the document will spur others to undertake fur-ther studies as well as research to document stories and analyse the promotion, uptake and use of manually drilled boreholes. In addition, the compendium should also enable those promoting manual drilling to realise that they are certainly not alone in their endeavours!

Code of Practice for Cost Effective Boreholes British English Version, June 2010

Sustainable groundwater development is fundamental in order to provide universal access to safe drinking water. This document, The Code of Practice for Cost Effective Boreholes provides a basis for the realisation of economical and sustainable access to safe water. The term “cost-effective” means optimum value for money invested over the long term. Boreholes are drilled to function for a lifespan of 20 to 50 years. Thus, the lowest cost is not always the most cost-effective, particularly if construction quality is compromised to save money. Cheap drilling or poor construction quality can lead to premature failure of the well or contamination of the water supply. Boreholes that are subsequently abandoned by the users are clearly not cost-effective.

The Code of Practice for Cost-Effective Boreholes has been officially endorsed by the German Federal Institute for Geosciences and Natural Resources (BGR).

Handpump Standardisation in Sub-Saharan Africa: Seeking a Champion RWSN Publication 2015-1

Downloads:


Author: MacArthur, J.
Year of Publishing: 2015
Publisher: RWSN
Institution:

Handpump standardisation is the formal or informal mechanism that governs the varieties of community handpumps used within a particular country. In a handful of countries this also includes stand-ard handpump designs. With over a million handpumps in sub-Saharan Africa and new installations every day, handpump standardisation is still vital for the policy and practices of governments and implementing organisations. While rural water practitioners are polarised about the future of formal standardisation, the extent of informal standardisation is of significant importance to the sustain-ability of handpumps across the continent. Of the thirty-five countries in sub-Saharan using handpumps, formal standardisation has emerged in fifteen through regulations (nine countries), and endorsements (six countries). However in the remaining countries, informal standardisation determines what handpumps are installed where, either through recommendations (fourteen countries), or de facto standardisation (six countries).

Institution: RWSN

The high rate of non-functional boreholes in many parts of the world is attributable, in part, to a lack of professionalism in the drilling sector. In order to increase access to a safe and sustainable water supply, competent and experienced drilling contractors must be engaged. Likewise, suitable equipment is needed and experienced consultants are required to supervise construction.
This guidance note assists project managers involved in the provision of groundwater supplies using boreholes. It sets out procurement and contract management procedures that will lead to the engagement of professional groundwater consultants, drilling contractors and suppliers. The publication will enable clients to ensure that they have the know-how to get the expected results out of drilling contracts.
