Clean, accessible water — one of life’s basic necessities — saves lives around the world, but in some regions, including Africa, the Caribbean, Central America and South America, villagers walk miles to collect water from a potentially contaminated source. Missionaries improve the villagers’ quality of life by drilling community water wells. Even in the best of circumstances, a maintenance or repair issue can emerge when drilling a well, potentially delaying the project significantly — or, in the worst case, indefinitely. And with their limited timeframes, missionaries seldom have time for a standstill in production.
