Context
In India, the number of towns and cities with over 5,000 inhabitants has grown by around 50 per cent during the past decade and now stands at almost 8,000. These are home to 31 per cent of the total population. This continuing trend means that half of the Indian population will be living in urban areas by 2030. The development of infrastructure and services for the water supply and wastewater management systems has been unable to keep pace with this population growth. Consequently, only around 10 per cent of all towns and cities have a sewerage network; even then, these systems serve only parts of the town or city. This means that a large proportion of wastewater does not even reach sewage treatment facilities, many of which are faulty, insufficiently dimensioned and poorly operated and maintained. The untreated wastewater flows directly into surface water and groundwater and pollutes them.
With the National Urban Sanitation Policy (NUSP), India's Ministry for Urban Development launched comprehensive reforms for municipal wastewater management and the improvement of sanitation in 2008. This sector continues to be a focus of the Government and has been receiving increased attention since the national elections in 2014.
Despite the enabling political conditions, the city administrations lack the expertise required to plan and provide the necessary infrastructure and services properly.
Objective
Indian states and their towns and cities are taking effective measures to combat the introduction of untreated wastewater into surface water and groundwater.
