Abstract
The catchment areas of major storm water drains in Jodhpur, Rajasthan, are comprehensively covered with sewerage network. Even though almost all storm water drains carry sewage as dry weather flow round the year.Raw sewage flowing in these drains remain stagnant at many locations due to heaps created by solid waste dumping causing mosquito breeding and odor problems and pose a threat to the health of the inhabitants of the surrounding area.The stagnant sewage in storm water drains also causes pollution to the ground water which is very shallow 2-5 meter below ground level in many areas of the city areas.Thus, Raw sewage flowing in major storm water drains (MSWD) discharging directly into Jojari river are one of the major causes of pollution in Jojari River.Similarly, MSWD terminating within the city areas i.e. not extended up to Jojari River are also causing environmental problem in city areas through which these drains flow and or terminating near habituated areas.Previous study has found that the channel section is inadequate to pass design flood safely. It has been reported that during the rainy season of 1979 unprecedented flood occurred and flood water over flanked the river banks to an average distance of 300m either side at many locations between Banad and Jhalamand. Since then due rapid increase in citys population, many new habitation have developed near the banks of river.Therefore, in our study we shall focus on Need and Challengesto to Prevent Pollutionfrom existing river streams passing from the cities, and converting the existing Hazardous environment into a public water front.Keywords: Need and Challenges , storm water drains , Analysis, investigation, research
