"Saph Pani" - Enhancement of natural water systems and treatment methods for safe and sustainable water supply in India.
The project aims at enhancing water resources and water supply particularly in water stressed urban and peri-urban areas in different parts of the sub-continent. The objective is to strengthen the scientific understanding of the performance-determining processes occurring in the root, soil and aquifer zones considering the removal and fate of important water quality parameters such as pathogenic microorganisms and respective indicators, organic substances and metals.
The project focuses on a set of case study areas in India covering various regional, climatic, and hydrogeological conditions as well as different treatment technologies. The site investigations include hydrological and geochemical characterisation and, depending on the degree of site development, water quality monitoring or pre-feasibility studies for new treatment schemes. Besides the actual natural treatment component the investigation may encompass also appropriate pre and post treatment steps to improve water quality or avoid clogging of the sub-surface structures.
The experimental and conceptual studies will be complemented by numerical modelling which helps to predict responses to changing conditions and to transfer results to other regions.The project consortium comprises 20 partners mainly from Europe and India. The Hydrogeology Group of Freie Universtaet Berlin is involved in two case studies (Delhi and Chennai), to some extent also in Raipur. In order to strengthen the cooperation in the field of teaching and student exchange between Anna University in Chennai and Freie Universitaet in Berlin, a cooperation agreement was signed between both universities.
