Mum­bai’s much-ne­glected sew­er­age sys­tem is all set to get a makeover. The Bri­han­mum­bai Mu­nic­i­pal Corporation (BMC) has made a Rs 244 crore pro­vi­sion to lay new lines and up­size old ones, in­clud­ing 14-km-long lines along the banks of the Mithi river. In ad­di­tion to this, the civic body has also al­lo­cated Rs 474 crore for the waste­water treat­ment fa­cil­ity (WWTF) project and pump­ing sta­tions, and Rs 150 crore for reg­u­lar sewage op­er­a­tions, mak­ing it a to­tal of Rs 868 crore cap­i­tal ex­pen­di­ture for the sewage sys­tem’s over­haul.

The to­tal length of Mum­bai’s sew­er­age sys­tem is 2,006 kms, cov­er­ing 83 per cent of the de­vel­oped area and 67 per cent of the city’s pop­u­la­tion. In or­der to en­sure 100 per cent sewage con­nec­tiv­ity, the BMC has com­menced the Mu­nic­i­pal Sew­er­age Im­prove­ment Pro­gramme (MSIP) in 2016-17. Un­der Phase-i of the pro­gramme, 94 kms of sew­er­age lines were to be laid or up­sized, of which work on 33 kms is still in progress. “The BMC is spend­ing Rs 385 crore on this. It has also pro­posed a fur­ther 12 kms of sew­er­age lines, which would cost an­other Rs 74 crore in the next fi­nan­cial year. All 94 kms of lines are to be com­pleted by 2023-24,” a BMC of­fi­cial said.

Phase-ii of MSIP in­volves lay­ing of 143 kms of sew­er­age lines on un­der­de­vel­oped Devel­op­men Plan roads and SRA lay­outs. As of date, per­mis­sion has only been granted for 10 kms of these. Phase-iii of the net­work would see sewage from the slums be­ing car­ried out us­ing sew­er­age lines and un­der­go­ing waste­water treat­ment fa­cil­ity. The BMC has also made a Rs 42 crore pro­vi­sion for lay­ing of Rs 12 kms of sew­er­age lines along the Mithi river.

WWTF project has been de­layed for 14 years. The BMC will up­grade seven pri­mary cen­tres to sec­ondary and ter­tiary treat­ment plants — at Worli, Ghatkopar, Bhandup, Versova, Co­laba, Ban­dra, and Malad and build a new one in Dhar­avi. The es­ti­mated cost of up­grad­ing all seven cen­tres is around Rs 14,000 crore. The BMC had al­lo­cated Rs 242 crore, while pro­vi­sion of a fur­ther Rs 100 crore would be made for var­i­ous pump­ing sta­tions, sew­er­age tun­nels, STP at VJB Udyan, etc.
