PUMPING TEST ON ELEVEN NEWLY DRILLED BOREHOLES IN THE CENTRAL AND WESTERN REGIONS OF GHANA

About the Project

4Ward Development West Africa, in their quest to expand access to safe and reliable water supply to communities in Ghana, engaged the services of our firm, Atlantic Hydro-Engineering Services Limited, to carry out pumping tests on eleven (11) newly drilled boreholes in the Central and Western Regions of Ghana.

The locations of the boreholes are indicated as follows: Twifo Praso Bakyease Twifo Praso, Confidence Ntafrewaso, Twifo Hemang Forever Young, Twifo Hemang Continuation, Gyankobo Odumase Abrafo Abrem, Agona Sekyere, Hemang Komenda Kissi (existing Borehole)

Objectives of the Borehole Assessment
The objective of the project was to assess the status of the boreholes for possible mechanization.

Scope of Work
The scope includes among other things, the following:
Carry out a 3-hour step drawdown test at one (1) hour per step for three (3) steps on each borehole 12-hour constant pumping test on each borehole 6-hour recovery test on each borehole.

Methodology and Data Collection:

• Pumping Test: Involved pumping water from each borehole at a constant rate to measure drawdown over time.
• Data Analysis: Parameters such as hydraulic conductivity, transmissivity, and storability of the aquifer were determined from the collected data. These parameters are crucial for effective groundwater management and designing sustainable water supply systems.

Conclusion: The pumping tests provided valuable insights into the performance and characteristics of each borehole. This data will aid in making informed decisions regarding the mechanization and utilization of these boreholes to enhance water supply infrastructure in Ghana.

In summary, the project aimed to ensure that the newly drilled boreholes meet the standards necessary for sustainable water supply, thereby contributing to community development and improved access to safe drinking water in the Central and Western Regions of Ghana.
