Present Water Supply Scenario:

The entire beneficiaries, ULBs and rural habitations are provided with protected water supply schemes with Infiltration wells, Openwells and borewells. During summer months extraction of ground water for agricultural activities are noticed which promotes the depletion of water level and hence there is inadequacy of water supply to these beneficiaries.

Need For The Proposal:

Due to the proximity of Madurai City, middle class population settlement has increased in the sub urban towns, thereby increasing the water demand in the proposed towns covered under Local Planning Areas. Moreover, UGS Schemes have been proposed in all the towns (except A.Vellalapatti, Alanganallur, Palamedu, Singampuneri Town Panchayats and Melur Muncipality). Rural habitations are supplied with local sources such as borewells and the sustainable level of service is 10 lpcd. In order to enhance the level of service to 40 lpcd, for rural habitations and 135 lpcd for the Municipalities with UGSS contemplated and 70 lpcd for Town Panchayats and 90 lpcd for Municipalities without UGSS, it necessitated to formulate the above CWSS with river Cauvery as source.
