The crisis of the Great Flood of 2011 caused severe damage to people and property and also impacted negatively the Metropolitan Waterworks Authority (MWA), resulting in the contamination of the national water supply. The MWA had to improve the quality of raw water by using more chemicals in order to raise the water quality in accordance with water supply production standards for human consumption, accelerate the reinforcement of the permanent embankment along the Prapa Canal, repair leaking pipes as well as assist flood victims by delivering mobile water production units for serving potable water, distribute disaster relief packages, bottles of drinking water, and employ remedy measures, for instance, the reduction of household water charges to provide a degree of financial relief.
