Author: UNICEF
Year of Publishing: 2009
Publisher: UNICEF
Institution: Practica Foundation, EnterpriseWorks/VITA

For the construction of safe groundwater points different well construction methods exist. Wells can be drilled with machines, drilled manually or dug by hand. Before selecting the most appropriate method, several criteria, such as geology, depth of aquifer, yield and location should be reviewed.

Publisher: UNICEF
Institution: Practica Foundation, EnterpriseWorks/VITA

Achieving the MDGs for water supply in Sub-Saharan Africa is a daunting task because the magnitude of the problem is ever increasing. There are 284 million people living in rural areas without access to potable water. In order to reach these people, radical solutions, and low-cost soutions are needed - such as manual drilling.

Year of Publishing: 2009
Publisher: RWSN
Institution: Cranfield University, UNICEF, SDC, Skat

This Borehole Costing Model is a spreadsheet in Microsoft Excel 2003

Once set up the model can quickly calculate the actual cost of a borehole (not the price). The first time the model is used it requires the unit costs to be entered for different materials and rigs. The model was built by Tom Heath, Richard Carter and Kerstin Danert. The model consists of three components: Model Unit Costs, Borehole Specifications and Results.

Institution:

From the UPGro Catalyst Project "Optimising Road Development for Groundwater Recharge and Retention"

This research has demonstrated that the road in the study area is having significant negative impact to the agricultural livelihoods, but that also it has a huge potential to be a key contributor to the enhancement of the livelihoods. The three major recommendations are :( 1) for the betterment of the impacts, it is suggested that Roads for water harvesting and multiple uses be mainstreamed in educational systems (2) There should be integration between relevant institutions and authorities (ERA, MoA as well as regional and zonal line offices) in making future road development plans. And (3) Awareness generation should be done to encourage farmers utilize the runoff from roads for productive purposes. Moreover, technical assistance and training's needs to be delivered at grass-root level.

An Assessment of Hand Drilling Potential in Upland and Lowland Malawi MSc Thesis Academic Year 2006/7

Author: SUTTON, I.
Year of Publishing: 2007
Publisher: Cranfield University
Institution:

Hand drilling methods can offer low cost, rapid access to shallow, unconsolidated aquifers typically found in dambo environments (seasonally waterlogged African wetlands).
This thesis presents the findings from an evaluation of three hand drilling techniques (augering, percussion drilling, and borehole jetting) regarding to their suitability for groundwater supply in upland and lowland dambos in Malawi.

This note may serve as guideline on how to combine roads and water harvesting. The investment in roads in almost any country far exceeds that in local water management or watershed protection. Hence roads offer one of the largest opportunities to secure local water supplies, if done wisely and in an integrated way. This document describes both the governance and proceses to combine road development with water management as well as how recharge, retention and reuse (3R) of water can be enhanced through improved designs.

Code of Practice for Water Well Construction NIGERIAN INDUSTRIAL STANDARD

Downloads: 187


Author: STANDARDS ORGANISATION OF NIGERIA
Year of Publishing: 2010
Publisher: STANDARDS ORGANISATION OF NIGERIA
Institution: STANDARDS ORGANISATION OF NIGERIA

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.

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.

Bush Pump Zimbabwe Standard Specification

Author: RWSN/DWRD
Year of Publishing: 2004
Publisher: The Zimbabwe Government
Institution: Department of Water Resources and Development

The Bush Pump has been used in Zimbabwe for over 60 years. It was first designed in 1933 by Tommy Murgatroyd, a water suuply office working in Plumtree, Matebeleland, and some of his early pumps survive to this day.

The Zimbabwe 'Bush Pump' is almost unique on the African continent in that it was conceived and designed and is wholly manufactured within Zimbabwe itself. The family of 'Bush Pumps' owe their success to a simplicity of design and rugged construction which originated from Murgatroyd's pioneering work. The Bush Pump continues to serve the people of Zimbabwe, seventy years after the first pumps of the family were designed and built.
