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! | »
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). | »
The abstracts below were submitted and presented at the 41st Congress of the International Association of Hydrogeologists in Marrakech (15-19 Sep). They draw on work funded through the UPGro programme.

The Rural Water Supply Network (RWSN) is continuing its work on cost-effective boreholes under its theme of Sustainable Groundwater Development. The network is supporting stakeholders to improve borehole drilling policies and practices. As part of this effort, UNICEF and Skat Foundation are collaborating on manual drilling in Africa. The 2012 to 2014 collaboration documented and facilitated exchange on the introduction and professionalization of manual drilling in more than 20 countries.
This report is about the role played by manually drilled boreholes in meeting water needs in Lagos city, Lagos State and more widely in Nigeria. By examining Nigeria, the report draws out key lessons for those who are promoting, or trying to regulate manual drilling in other countries. It is hoped that this report, and the accompanying photo/video documentary and blogs will trigger action to better support manual drilling efforts in Lagos, in Nigeria and in other countries. | »
This Nigerian Code of Practice for Well Construction was elaborated by the Technical Committee for Water Well Construction.
Groundwater development is one of the sources of the Federal and State Governments Water Supply Intervention Programmes under which government embarked on construction of open wells and boreholes in order to increase access to portable water to Nigerians. However, water well construction is still characterized by cases of “failed hole”, poor quality service, and unprofessional conduct of drillers and lack of established code to regulate the practice of water well drilling in Nigeria. These are serious concern to government, donor agencies and sector stakeholders who see them as militating factors towards attainment of water supply project objectives in particular and Millennium Development Goals (MDGs) in general. This Code of Practice was therefore elaborated to provide the framework for water well construction in Nigeria.
In the elaboration of this Code of Practice, reference made to Nigerian Industrial standards and National standards of other countries are acknowledged. | »
