Joissam Ghana

Joissam Ghana is a private civil works company that is improving access to clean water throughout the country by identifying potential water sources, drilling, and installing water systems to filter and deliver water.

Water is a scarce commodity in parts of Africa. In Ghana, it’s estimated that 22 percent of the population — or around 6 million people — lack access to clean drinking water. To date, the company has drilled over 3,000 bore holes in Ghana — holes that extend deep into the ground into aquifers — and has installed about 10,000 hand pumps, resulting in improved water access for four million people.

Going forward, Joissam Ghana plans to further embrace its mission “to enhance the quality of life” for others by helping them to access natural resources. The company has an ambitious goal of helping to provide clean water to close to 13 million of Africa’s most needy and vulnerable citizens by 2025.
