Borehole
Welcome to the borehole team!
The main objective of our team is to ensure that a borehole of acceptable quality is installed in Adu Achi by a reputable company.

A brief review of groundwater for rural water supply in sub-Saharan Africa
"Co-ordinated groundwater research and data collection has become more difficult in SSA due to decentralisation and demand responsive approaches to the provision of rural water supplies. Information is rarely collected from the many thousands of boreholes drilled each year, with the result that the same costly mistakes are made time and again. However techniques are available to allow local institutions to collect high value data from ongoing drilling for little additional cost. The use of these techniques could allow local institutions to assess the nature of groundwater resources in their areas and, with proper documentation and networking, increase the knowledge base of groundwater in Africa. Budgets for groundwater research in Africa could then be targeted to issues that cannot be addressed by improved data collection from ongoing drilling. Such a scenario will only occur with the dissemination of simple techniques in groundwater resource assessment to those involved in rural water supply, and when the benefits of such assessments are seen within individual water projects."| Attachment | Size |

Simple methods for assessing GW resources in low permeability areas of Africa
"This manual aims to be a first step in providing useful information for project engineers working on rural water supply projects in sub-Saharan Africa. The focus is on low permeability aquifers, where groundwater is difficult to find."
Borehole Objectives
Borehole Team
Members: Rimas Gulbinas, Sheri Northcutt, Colleen Lyons, Stephen Enriquez, Brian Chung
Overall Goals and Objectives
Develop a list of different drilling techniques - October 24th
Internet Research
Find out how surrounding boreholes were drilled and what kind of geology is present (hopefully sand/gravel!)
Outline a budget for our team - October 24th
Find some Nigerian Borehole companies
Estimate standard drilling costs beyond those previously obtained
Find out how deep and wide the hole will be, what kind of pump test will be performed, and what kind of pump (will boreline be utilized or just conventional drilling)
Identify and contact borehole companies – October 31st
Confirm preliminary drilling estimates
Create list of different pump tests offered locally
Collaborate with pump team; see if they have any requests while we contact the companies
Select a company for drilling/testing - November 15th
Compare prices, times, reputations, experience
Contact company and confirm selection, finalize plans
Proceed with test and obtain results - November 20th
Analyze Data - November 30th
Research how data should be interpreted
Contact any potentially helpful professors for advising
Present findings to Pump Committee
Complete analysis and make final recommendation to the Project Team
Recycle our group members back into the EWB machine - November 30th
Status Report-Specific Goals (Identify what you hope to achieve by each of the status reports)
By October 25th (Status Report 1)
By the first status report our team will have become familiarized with the different methods of borehole drilling and will be competent enough to present its findings to other groups. We will have identified local drilling companies, and if any additional companies beyond those previously encountered exist. A cost estimate will be performed and the preliminary results handed over the appropriate party.
By October 31th (Status Report 2)
A cost estimate will be confirmed by contacting and communicating with the local drilling companies. The types of tests offered by each company will be analyzed, and the varying costs compared. A final decision on the company and type of pump test will arrived at by Nov 15th and the company will be notified. A pump test will be performed by Nov 20th .
By November 30th (Status Report 3)
As the epic saga of the borehole team approaches completion, the pump test data will be finally analyzed, hopefully in conjunction with a professor, and a final report will be prepared for the pump committee. Any recommendations arrived at over the semester, especially if they come from the pump test company, will be communicated.
