The piped water supply in Egypt increased between 1990 and 2010 from 89% to 100% in urban areas and from 39% to 93% in rural areas despite rapid population growth. Over that period, Egypt achieved the elimination of open defecation in rural areas and invested in infrastructure. Access to an improved water source in Egypt is now practically universal with a rate of 99%. About one half of the population is connected to sanitary sewers.
