This publication, “Facilitator Toolkit on Gender Mainstreaming in Urban WASH”, is one of the outputs from the “Water and Sanitation Improvement in Informal Urban Settlements through Gender Mainstreaming and Capacity Building of Local Authorities Project” implemented by UN‐Habitat from 2009 to 2011. The project started with the conduct of provincial workshops on Gender Mainstreaming in Urban WASH and concluded in a Natonal workshop in Islamabad. During the project implementation in twenty four informal urban selements of seven major cites of Pakistan, the need for this toolkit was reiterated to facilitate inclusive decision making process for improved access of urban women to water and sanitation. This is due to the fact that women suffer most from poor water supply and sanitaon particularly in urban informal settlements where the government does not include them in the development plans of the city. In informal urban settlements, women and girls are over‐burdened with the task of fetching water with the additional responsibilities of earning livelihood and other non‐productive actvities. They face daily indignity and insecure owing to lack of private latrines and open waterfetching spaces. In addition, they are also confronted by security risks associated with the use of poorly located and insecure public facilities. Many girls at puberty dropped out for lack of adequate sanitaon facilities in schools.
