The 2011 Sindh floods began during the Pakistani monsoon season in mid-August 2011, resulting from heavy monsoon rains in Sindh, eastern Balochistan, and southern Punjab. The floods have caused considerable damage; an estimated 434 civilians have been killed, with 5.3 Million people and 1,524,773 homes affected. At least 1.7 million acres of arable land have been inundated as a result of the flooding. The flooding follows the previous year's historic 2010 Pakistan floods, which devastated the entire country. Unprecedented torrential monsoon rains caused severe flooding in 16 districts of Sindh province. FWO was asked to deploy its resources for repair of Tori Bund which was a herculean task which was completed within fortnight thus saving a large population from further miseries of flood water.
