The water which is supplied to a community consists of range of chemical substances and microbial flora. Due to these, the waste water acquires the potential to pollute the environment. The sewerage of an urban city flowing directly in river and via lake without treatment, is polluting these natural courses heavily and thus creating unhygienic condition within and around the city. This also contaminates the underground water. Treatment of this sewage is essential before its disposal to natural water bodies. . In the present work, sewage treatment scheme of an urban city in India has been analysed and future projections have been made for the sewage generation. In the current study, future treatment requirement has been estimated on a medium term (target 2030) and long term (target 2045) basis. The results obtained are very much useful in identification and rectification of balance need for Sewage treatment plant and sewer network for the future expansion.
