Water audit at the city scale allow Corporation to understand the potential sources, the ward wise and sector wise demand for water and the spatial variation of scarcity in the corporation area. SWI collected and analyzed the secondary and primary data collected in this study to develop the water balance for the city and using GIS platform mapped the water stress in the area for the present conditions and for various scenarios in future.
VISUAL MODFLOW simulations were carried out to assess present status of salinity intrusion in Cochin. A forecast of salinity intrusion in the study area for next decade was also assessed for various scenarios.
Kerala Water Authority ( KWA) is the main source of water supply in Kochi. The existing water distribution network of KWA is analyzed for the first time using EPANET. An assessment of the network for its sufficiency to meet future demand is carried out and recommendations are made for improvement..

Though about 200 MLD water is supplied by Kerala Water Authority to Kochi Corporation area, the actual quantity received at the end is much lesser due to losses in the distribution line, popularly known as non revenue water (NRW). So far there is very limited understanding on the quantity of NRW in the area. SWI conducted detailed investigations to understand the amount of NRW within a DMA in Kochi corporation area in collaboration with Kerala Water Authority.
SWI in association with Koratty Panchayat has collected water from 190 drinking water sources like domestic and public wells and analyzed for various water quality parameters as per Bureau of Indian Standards. All the water sources were later documented using geographic Information system (GIS) to prepare a water quality atlas. It was found from the results of analysis that 90% of the drinking water sources were contaminated by Coliform bacteria. Another significant observation was the presence of high acidity, Iron and Fluoride in certain wells. Remedial measures were advised and the Panchayat has adopted necessary measures promptly.
This water quality atlas will be extremely useful for the water related planning process in view of decentralized planning process of Koratty Panchayat. The atlas is prepared such that it can be updated in every six month.
