Treated Sewage To Re­vive Bengaluru Lakes

Sustainabilitynext - - Front Page -

The much-awaited ini­tia­tive to treat most sewage water for re­use is all set to take off in Bengaluru. This water will be di­verted to fill up 65 lakes in Bengaluru Ur­ban, Bengaluru Ru­ral and Chikka­bal­la­pur districts. The foun­da­tion stone for the Rs 883-crore project at De­vana­halli has been laid and the project is sched­uled to be com­pleted in less than two years.

A re­port in Dec­can Her­ald stated that nine lakes in the De­vana­halli taluk of Bengaluru Ru­ral district, 12 in Bengaluru North taluk of Bengaluru Ur­ban district and 44 in Chikka­bal­la­pur district would be cov­ered un­der this project, which in­volves car­ry­ing 210 mil­lion litres per day (MLD) of treated sewage water through pipes. The project is ex­pected to im­prove the ground water ta­ble sig­nif­i­cantly.

“This is a first-of-its-kind project in In­dia,” Mi­nor Ir­ri­ga­tion Min­is­ter T B Jay­achan­dra told re­porters. “The project im­ple­men­ta­tion pe­riod is 18 months, but if we man­age to get clear­ances faster, it will be com­pleted be­fore that.” A sim­i­lar project is un­der way in the Ko­ra­man­gala & Chal­laghatta val­ley to fill up the lakes of Ko­lar district, he added.

Au­thor­i­ties hope the project would also help re­ju­ve­nate four dead rivers that orig­i­nate right in Bengaluru’s back­yard - Ut­tara Pi­nakini, Dak­shina Pi­nakini, Chi­tra­vati and Pa­pagni. Th­ese rivers have been dead for nearly 20 years now.
