  • Why is sewage treatment a problem in India?
  • In most of the urban centres of India, domestic, industrial and storm waters are discharged into the same system and as a result, wastewater use/treatment is getting confounded. The sewage treatment capacity in India is only a fraction of the sewage produced and therefore, much of the irrigation with wastewater is untreated.
  • Should treated water be repurposed in India?
  • While policy and guiding frameworks in India acknowledge the need for reuse of treated wastewater, the design and operation and maintenance aspects for the management of such projects and tariff structure for the sale of treated water for various applications have not been taken up aggressively.
  • How a wastewater treatment system is used in India?
  • Another cost-effective and environmentally friendly wastewater treatment method utilized in India is Vermi-filtration. It is an advanced form of vermicomposting. It uses earthworms to digest suspended particles, break down organic matter with enzymes, aerate the system through burrowing, and remove pathogens in a biofilter.
  • What is the future of wastewater reuse in India?
  • Wastewater reuse in India is expected to expand greatly in the future owing to various opportunities in the water and wastewater sectors. The focus is shifting to find solutions for the effective management of water resources.
