Daventry resident Helen Robertson visited Makueni County in Kenya earlier this month to see first-hand the impact two new sand dams and a water tank were having on the local community.
It is hoped the new water facilities will provide safe, clean water to homes and the local school.
Ms Robertson is a marketing manager at Cambridge Weight Plan, which has formed a partnership with water aid charity Just A Drop, aiming to raise £50,000 for the charity in 2014.
She said: “I am so proud to have been part of something that is helping mothers in Kenya to be able to give their children what is best for them and making their lives just that bit easier. Just a small amount of money makes a huge difference, and I have now seen that first hand.”
