Supporting consolidation, replication and up-scaling of sustainable wastewater treatment and reuse technologies for India (SARASWATI)
Date du début: 1 sept. 2012, Date de fin: 28 févr. 2017 PROJET  TERMINÉ 

The poor condition of sanitation and wastewater management in India (as in many Asian countries) is well documented and has recently led the Asian Development Bank to call for a revolution in wastewater management across Asia. Conventional, centralized approaches have failed in many areas and will hardly be able to solve potential problems in rural, hilly and rapidly developing urban areas in India. Instead, innovative, decentralised systems aiming at various benefits are needed. A main benefit in the context of SARASWATI is the reuse of treated wastewater for different purposes. Other benefits include reuse of energy and nutrients, which are also important. Despite the overall poor condition of wastewater treatment across South Asia, India has already considerable experience with such decentralised approaches. Over the last decade, hundreds of decentralised wastewater treatment plants of different technology types have been installed all over India. However, not all are functioning well and several also failed, due to various reasons. Also, there is no consolidated evaluation and review of all those existing plants available. As a result there is only very limited knowledge on the performance of those existing technologies available and a review and evaluation of those plants is very timely in order to derive sound conclusions and recommendations for future wastewater management strategies in India. SARASWATI will perform such a comprehensive and independent evaluation and hence provide key suggestions for the improvement of existing technologies. In addition, SARASWATI aims at deploying selected proven EU technologies with a potential for solving grave water challenges in India (water pollution due to discharge of untreated wastewater and storm-water, water scarcity and groundwater depletion, unhygienic sludge handling practices due to lack of suitable technologies). Water challenged sites have been identified in 5 Indian States comprising almost all regions.
