Since its creation in 1989, the spread of the Circuit Rider program across Central America has been astounding. It all began with seventeen communities in Honduras. News of the program's success spread to neighboring communities, resulting in the continued growth and popularity of the program. Today, it has grown to support more than 650 community water systems across Honduras – benefiting more than half a million people.

The program has experienced similar success in El Salvador, where a small Circuit Rider Program was established in five communities to provide clean water in the aftermath of a devastating earthquake in 2001. Today, the program is self-sustaining, reaching 72 water systems. It is expected to reach 150 more communities in ten departments by 2012 – benefiting 185,000 inhabitants.
