Helping people to help themselves... to live saving clean water. Giving children something really fun to play on, at the same time, allowing them to stay in school rather than having to help haul water. This is not exploitation of child labor, it is genius. Using the water tower for advertising, which in turn pays for the maintenance of the system... this is right use of business. I do hope the advertisers are screened so that only needed, life supporting goods and services are advertised.
