 For almost 30 years, the whole urban water organization was planned and carried out by the General Water and Sanitation Committee within the SRH.At the local level, federal Water Boards facilitated some local participation but actually also depended on the SRH.In 1971, during the presidency of Luis Echeverría (1970–1976), a new committee for water supply and sanitation systems was introduced by SRH facing a high increase in urban population which exceeded the centralized system's capacity to provide services.
