Résumé partiel
This study by Gujarat Technological University (GTU) under PhD programme is taken to assess quality of water supply in all ULBs area and help them to suggest technological options to improve the quality of water in case of any issue in quality of water. It is also aimed to develop MIS for ULBs and make available aneroid based app to citizens of urban Gujarat to know quality of drinking water available to them at any point of time. Gujarat is a state in Western India, with population in excess of 60 million (Census 2011). Gujarat is one of the most urbanized states of India. It has an urban population of 24 million accounting for 42.6 % of total population (Census 2011). Gujarat falls under semiarid zone. The long sea coastline along Saurashtra, Kutch and other parts creates the problem of salinity ingress, which affects the ground water quality on coastal belt and because of scanty and uncertain rainfall, the replenishment in dam is also not reliable, hence this areas are always under water deficiency. Data have been collected from all 167 ULBs of Gujarat state. There are 8 Municipal Corporations and 159 Municipalities (Directorate Of Municipality, 2015). Responsibility of water supply in all these cities lies with Urban Local Bodies and water supply is largely concerned in cities of Gujarat (BPMC Act 1949 & Gujarat Municipalities Act,1963) . Based on data collection and analysis it is found that, about 80% house-holds are covered by water supply. Total production of water is about 4100 MLD (GUDM, 2016). About 21% of total production of water is dependent on ground water while 66% is in form bulk purchased water. There is disparity in level of water supply in 92 ULBs, out of total 167 ULBs water supply is less than 100 LPCD. An average duration of water supply in all ULBs is about 1.5 hours. All WTP in the state are conventional Rapid Sand Filter Plant. No advance technology like UV/ Membrane based/ High filter is being used. Due to high level of dependency on ground water, more than 10% of people. This leads to risk of chemical contamination like fluorides, Nitrate, TDS, Salinity etc., High level TDS and salinity is common scenario across the state, while problem of salinity water quality is common in west Saurashtra & Kutch area.. Excess fluoride in North & Central Gujarat and excess Nitrate in Central & South Gujarat are found In many cities it is observed that, due to low quantity of water supplied, people often go for tapping private water sources and eventually in many cases it turns out to be ground water, this is an additional risk.
