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

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.

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.

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
