This study report by the Water and Sanitation Programme (WSP), a global partnership administered by the World Bank suggests that inadequate sanitation causes India considerable economic losses, equivalent to 6.4 per cent of India's GDP in 2006 at Rs. 2.4 Trillion. It analyzed the evidence on the adverse economic impacts of inadequate sanitation, which include costs associated with death and disease, accessing and treating water, and losses in education, productivity, time, and tourism. The findings are based on 2006 figures, although a similar magnitude of losses is likely in later years.

The study focused on the safe management of human excreta and associated hygiene behavior. The methodology adopted by the study included disaggregating the economic impacts of inadequate sanitation into health-related impacts including premature deaths, costs of treating diseases, and productive time lost due to illnesses; domestic water-related impacts including household treatment of water, and money and time costs to obtain safe water; welfare losses including additional time spent by people for accessing toilets or open defecation sites, and girls having to miss school, and women not going to work; and the loss of potential tourism owing to inadequate sanitation.

Data on incidence (e.g. diarrheal diseases, deaths, etc.) were compiled from national sources (National Family Health Survey, WHO Demographic and Health Surveys, and other Govt. of India sources). Based on scientific literature, attribution factors were used to estimate the populations impacted by inadequate sanitation. Economic valuation was carried out using costs/prices based on secondary studies.

This study by Geospatial World attempts to collect and analyse data concerning the catchment characteristics that affect direct runoff such as soil type, land cover and rainfall for the catchment of Lokapavani river in Karnataka using remote sensing and GIS techniques. An attempt has been made to determine the weighted average Curve Number (CN) for different land use, land cover and soil types in Lokapavani catchment in order to estimate the runoff.

This paper presents the results of a survey of WATSAN systems implemented under an Integrated Domestic Water Management (IDWM) project supported by Arghyam and implemented by MYRADA and MYKAPS in Bangarpet and H D Kote blocks of Kolar district of Karnataka. Arghyam has promoted Roof-top Rain Water Harvesting (RRWH) and eco-sanitation systems in its various project areas through its partner organizations.

This project aimed at developing an integrated approach to domestic water management. It focused on construction of RRWH and eco-sanitation toilets in four villages in the project area in Kolar with the aim of creating models of integrated management of domestic water and sanitation in a rural set-up.
