Mumbai has the fourth largest population in the world (12.4 million inhabitants, 2011 Census of India) this results in a lot of regular commuter flow from nearby towns, such as Navi Mumbai and Thane, resulting in a wide range of services. Mumbai has invested in expanding its basic services to meet the population's needs, such as water supply, solid waste disposal, and wastewater collection and treatment in order to meet its growing needs. However, there is a gap between what is offered and what is needed by the general public, creating a gap. The emphasis has been on urban sewerage treatment and disposal in centralized networks traditionally, using water for storage and treatment requires water use as well as well as capital and energy resources. According to recent figures, 50-80% of untreated wastewater flows into oceans until infrastructure is in place, Indian cities are forced to reconsider sanitation concepts should make full use of cost-effective and long-term solutions. This case study looks at 2 different projects in Mumbai, all of which are designed to improve the quality of the city's waste water and sewage system. Nature and electric-mechanical technology were investigated as part of the initial research for natural and electrical wastewater treatment. Three studies were chosen after a thorough investigation: on three different scales: community, organizational, and person levels. Usage of the land with little to no capital is applied in treating wastewater in all three of the case studies in this study, and returned to the site where it is made for re-use.
