  1. DOMESTIC SEWAGE GENERATION, COLLECTION , AND TREATMENT IN CLASS I CITIES

  2. SITUATION IN CLASS I AND CLASS II • Taking all the Class I Cities and Class II towns, CPCB has estimated that against the generation of 29,129 mld (based on 2001 population) the treatment capacity is only 6190 mld leaving a deficiency of almost 79%. Even taking into account additional 1743 mld planned addition, the gap remains at almost 73%. There are 302 Class I cities and 467 Class II towns having no sewage treatment facilities

  3. SITUATION IN CLASS I AND CLASS II (Contd.) • Add to this the fact that of the 115 existing STPs studied, 80 plants reported capacity utilization (70%) and only 70 (61%) met the standards for disposal in surface waters, • Thus not only 21% of sewage passes though treatment plants, only 60% of this sewage meets the required standards. Overall this means that only about 12% of sewage generated in Class I cities and Class II towns meets the standards for disposal in surface waters.

  4. GUJARAT • Do not have specific data on Gujarat and hope it is better than the national data • But Gujarat should take a lead in making a time bound program to see that at least the existing facilities deliver to their capacity, in terms of flow and in terms of compliance with disposal standards.

  5. GUJARAT • In parallel efforts should be made to upgrade these plants to permit maximum reuse and recycle for irrigation and industrial purposes. • Coupling of cities and industrial estates for such recycling of sewage is ideal for many cities and towns of Gujarat such as Vapi, Ankleshwar etc. • This will release water being used by industrial estates for domestic and other uses
