Status on Sewage Generation in Metropolitan Cities, Class-I Cities and Class-II Towns:

 

Discharge of untreated sewage in water courses both surface and ground waters is the most important water polluting source in India. Out of about 38000 million liter per day of sewage generated treatment capacity exists for only about 12000 million liter per day. Thus, there is a large gap between generation and treatment of wastewater in India. Even the treatment capacity existing is also not effectively utilized due to operation and maintenance problem. Operation and maintenance of existing plants and sewage pumping stations is not satisfactory, as nearly 39% plants are not conforming to the general standards prescribed under the Environmental (Protection) Rules for discharge into streams as per the CPCB’s survey report.. In a number of cities, the existing treatment capacity remains underutilized while a lot of sewage is discharged without treatment in the same city. Auxiliary power back-up facility is required at all the intermediate (IPS) & main pumping stations (MPS) of all the STPs.

 

Status of Municipal Wastewater Generation and treatment capacity of Metropolitan Cities:

 

  • There are 35 metropolitan cities (more than 10 Lac Population), 15,644 Millions Liter Per Day (MLD) of sewage is generated from these metropolitan cities. The treatment capacity exists for 8040 MLD i.e. 51% is treatment capacity is created.

 

  • Among the Metropolitan cities, Delhi has the maximum treatment capacity that is 2330 MLD (30% of the total treatment capacity of metropolitan cities)

 

  • Next to Delhi, Mumbai has the capacity of 2130 MLD, which is 26% of total capacity in metropolitan cities.

 

  • Delhi and Mumbai therefore in combination have 55% of treatment capacity of the metropolitan cities.

 

  • Some cities such as Hyderabad, Vadodara, Chennai and Ludhiana and Ahemedabad treatment capacity meets the volume of generation.

 

  • Cities like Delhi, Dhanbad have more than 50% capacity, rest of the cities have the capacity less than 50%.
