Abstract
Effective planning, development, and operation of wastewater management systems is one of the most essential components of urban infrastructure. In the absence of an effective system the limited fresh water resources are increasingly polluted and adversely affected, resulting in long-term damages to the ecosystems, and to public health at large. Examining the effects of the rapid growth of population in the urban centers along the revered Ganga river, the increasing pollution levels have spawned a number of initiatives to address the anthropogenic sources of pollution. Identifying the problem at the local level, major cities in Uttar Pradesh are evidently key contributors to the problem.
This paper deals with the concern of applying the technology of remote sensing and GIS for assessing and improving the sewerage infrastructures of an urban area. Evaluation of present sewerage facilities in respect to the present population, planning for additional infrastructure, and the installation of the same is required. This exercise has to be carried out with long-term future planning recognizing the time it takes to address these activities. Consequently, GIS facilitates the conceptualization of a solution that integrates present day reality with growth projections estimated for approximately 20 to 30 years in the future. The paper discusses in detail the strategy to bring all the existing sewage works into an orderly operation and provide new works to the necessary population in an effective and economical manner to assure the conservation of the environmental qualities. Keywords: Wastewater, Infrastructure, Pollution Control, Planning, GIS Applications
