In 2006, representatives of the International Rural Water Association (IRWA) visited Marcala, La Paz, Honduras with the desire to help improve the quality of water consumed by residents of the town. In early 2007 a small team led by Diana Cálix helped build the first treatment plant in the water source “Chiflador” with capacity of 550 gal /min that now serves more than 11,000 people in the city. After the plants completion, the team understood the need to provide technical assistance to water boards in rural areas in the department of La Paz to improve water quality, sanitation and health and hygiene in those communities. In 2008, Agua y Desarrollo Comunitario (Water and Community Development) obtained legal status as an NGO.
In 2010 ADEC was asked by Rotary Clubs from South Carolina USA to expand its program to the Department of Copan. Currently ADEC employees two Circuit Riders in Copan who are working with over 100 water systems.
In 2012 the Florida Water Alliance requested that ADEC expand the circuit rider program to include the Department of Lempira and with the financial support of the Florida Rural Water Association the first circurit rider was employeed in Gracias, Lempira and an office was established there.
