Sewage Treatment and Management in Goa, India: A Case Study

Water pollution in India is primarily associated with unmanaged urbanization, population explosion, inadequate capacity of sewage treatment, and its disposal, which lead to unhygienic and insanitary conditions. This paper gives an overview on sewage treatment plants (STPs) in Goa-a coastal state in India. Being a famous tourist destination, it is important to monitor and control water pollution levels in Goa state, so as to safeguard the health of tourists and thereby the economy of the region. The capacity-wise distribution of STPs was mapped against regional population distribution and drainage system of Goa using ArcGIS. This information will be very useful for further analysis of the allocation of STPs and its adequacy with regard to the population. A majority of STPs at Goa are managed by private authorities like hotels and resorts. Four municipal plants under Goa Public Works Department were evaluated.
