Abstract:
The purpose of the study is to manage the wastewater of East Delhi. The main focus
was on three aspects of wastewater management that are wastewater generation,
disposal and treatment. The aspect of wastewater generation attempts to evaluate the
amount of wastewater generation and problems caused by it. Further, the aspect of
wastewater disposal and treatment evaluates the efficiency of the sewerage network
present in the area and existing treatment capacity to analyse the potential to redevelop
the network for future population and increase the efficiency of the treatment of
wastewater. The study has been limited to NCT of Delhi only and no interference of
neighbouring states, i.e., Uttar Pradesh and Haryana has been considered. Wastewater
generation has been evaluated on the basis of population and water supply per capita
per day and treatment of wastewater has been analysed on the parameters of BOD,
TSS and dissolved sulphide in the wastewater. After analysing the above aspects of the
wastewater management problems has been identified. The problems of wastewater
disposal and treatment were analysed which was the growing gap between generation
and treatment of wastewater. Further, the disposal of wastewater is a problem, as the
disposal is directly into the river Yamuna of both treated and untreated water. These
problems were addressed and solved through interventions and proposals to increase
the efficiency of treatment of wastewater and minimise the disposal of wastewater to
river Yamuna by certain proposals for recycling and reuse of treated wastewater.
Overall, the aspects considered and evaluated in the thesis indicated that the study
area can increase the efficiency of wastewater disposal and treatment and help in
controlling the pollution in river Yamuna by adopting the proposed interventions while
being legally and logically reasonable.
