dumped in EWS Quarters V.2 Water availability & Usage Urban water systems will be affected by most of the predicted climatic changes: droughts will affect water supply and higher temperatures, besides increasing evaporation in supply lakes, could lead to the deterioration of water & water pipes contaminating fresh water. This risk, sits over and above other factors which threaten urban water supply like deforestation of catchment areas, reduction of seepage due to urbanization, and contamination of aquifers by modern development. The BWSSB which supplies piped water to Bangalore sources it from the Cauvery River (about 80% of total water supply) and the Arkavathy River (about 20% of the total water supply). In its website, the BWSSB admits that the per capita water supply at present in Bangalore is about 100 to 125 (gross) liters per capital per day (LPCD) which is below the National Standard of 150-200 LPCD for a city like Bangalore. However, the per capita availability of water for vast majority of poor people in Bangalore is only about 40-45 LPCD. One of BWSSB mandates is to provide bore wells in slums and poorer areas. The quality of water received in any slum, varies depending on the source and the extent of pollution. The below shows that both the city area settlements, KS Garden and EWS garden source a combination of BWSSB Cauvery water and borewell water, whereas Parappana Agrahara is mainly reliant on borewell water. The Cauvery water supply is limited to alternate days. People have to store double their daily requirement of water, if not more for emergencies. The graph tells us that of the 55 respondents in KS Garden, only 14 respondents, collect over 30 pots of water which is about 120-150 lpcd of water. Of these 14 respondents, a few like K6 and K16 capture at about 60 and 40 pots of water respectively. However, K4, K12, K38 and K55 have access to only less than 10 pots of water every alternate day, with K55 accessing only 3 pots of water in a day. In the neighborhood survey, we were told that over 50-60% of the dwellers do not have a BWSSB Cauvery water connection, and therefore they have to rely on neighbours for the drinking water requirements.
