Beyond their susceptibility to water-borne illnesses, children, and especially girls, were disproportionately affected by the lack of access to water. Girls are often responsible for collecting water, either at the borehole or at unprotected wells.[55] Inadequate water and sanitation services in school have a particularly negative impact on girls. A study conducted in Chitungwiza, a commuter town of Harare with water problems, found that girls who are menstruating face numerous challenges in attending school, including lack of appropriate disposal for sanitary pads, severe overcrowding with insufficient toilets, inadequate water supply and little provision for hand washing.[56]
