WASMO believes that drinking water management should be demand-driven and community managed. One of its main thrusts is the construction and maintenance of village level water supply infrastructure such as underground sumps, elevated storage reservoirs, stand-posts, pipelines, bathing and washing facilities and cattle troughs. In addition, both traditional and other existing structures such as open wells and tubewells are recharged and rejuvenated utilising local knowledge. Rainwater harvesting is an important component by which local supply sources are recharged. These local sources are supplemented by bulk transfer of water from water surplus south Gujarat to water deficient north Gujarat, Saurashtra and Kutch through canal and pipeline systems. The Gujarat Water Supply and Sewerage Board (GWSSB) and Gujarat Water Infrastructure Limited (GWIL) are involved in the bulk transfer of water from the Mahi and Sardar Sarovar canals. The GWSSB also establishes water treatment and filtration plants all over the state to treat and chlorinate water before it reaches the village sumps.
