SPATIAL ASPECT OF THE WASTEWATER MANAGEMENT SYSTEM: A CASE STUDY OF KHALISHPUR, KHULNA

Abstract

The urban wastewater management system is one of the most important infrastructures for an urban residential area and any kind of infrastructure has some spatial considerations. The conventional centralized wastewater management system is an enormous structure that generally fails to address the needs of residential areas for the collection and disposal of domestic wastewater from on-site sanitation. The decentralized management system is a promising but challenging option due to its spatial aspect i.e., specific areas required for implementation. This paper explores the grounds of wastewater mismanagement associated with the spatial aspects. For this purpose, research has performed a spatial analysis of Khalishpur, a residential area of Khulna city of Bangladesh. Two sample tissues in ward 12 were selected based on diverse spatial configurations. The study was led through an area survey, local people’s interviews, and Key Informant Interviews. Several maps, sections, and supporting drawings were developed based on the survey data to explicate the problems of wastewater management systems influenced by spatial aspects. Finally, this research has tried to find out the indicators of wastewater mismanagement aligned by spatial features. That will be helpful for the authority of area planning and wastewater management in combined to develop a wastewater management system focusing on the spatial aspects.
