The non-perennial Sabarmati river,which relies on the Narmada to keep it flowing throughout the year,is now likely to replenish its supply from the city’s treated sewage water,according to a proposal mooted by Ahmedabad Municipal Corporation (AMC).

“Today,Sabarmati has to be sustained by channelling Narmada water into it. But water from Narmada may not be available forever. Once work on Sardar Sarovar dam’s canal network is over,Narmada may not have requisite water for Sabarmati,” said AMC commissioner Guruprasad Mohapatra.

“Currently,we have a secondary treatment plant at Pirana,on the outskirts of Ahmedabad,where sewage water is being treated,” said Mohapatra.

A 60 mld (million litre per day) tertiary sewage treatment plant will be set up in Pirana using the latest technology,he added. “This sewage treatment plant will treat sewage water from Pirana and that flowing within the interceptor drainage lines alongside the Sabarmati river front before releasing it into the river,” said Mohapatra.

Currently,the secondary sewage treatment plant at Pirana treats 860 mld sewage water daily. The proposal,if approved,will not only keep Sabarmati flowing,but also aid aquatic life and provide farmers with clean water for irrigation.
