BMC to pump big money on sewage
Mumbai’s ancient system to get `868-cr makeover as civic body aims at 100% sewage connectivity
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.
