Water supply in North and East Nagpur areas to remain affected

The summer is yet to begin, but one can guess its intensity from water level in Kanhan river from where the city gets its supply. The water level has dropped to ‘alarmingly critical’ mark, forcing Nagpur Municipal Corporation (NMC) and Orange City Water (OCW) to request District Collector to move things for release of additional water from Totladoh dam.

The flow in Kanhan river as measured on Wednesday morning at the upstream Beena confluence was 129 MLD, which was ‘too less’ for Kanhan Water Treatment Plant (WTP) to operate at its full capacity. It adversely affected the morning water supply in North and East Nagpur areas of the city. Water supply may remain affected for a few more days, stated NMC-OCW through a press release.

Though the water level rose at intake wells on Wednesday, the situation continues to be ‘critical’. Due to scanty rainfall in 2017 and commissioning of Chaurai dam in the upstream of Totlahdoh dam in the neighbouring State of Madhya Pradesh, the water storage in dam was less than 30 per cent of its capacity. In view of approaching summer and demand for water, NMC-OCW requested District Collector for release of additional water in Kanhan river.

On instruction of Sachin Kurve, District Collector, Water Resources Department (WRD) released 50 Cusecs of water from chainage 19.4 Km on Right Bank Canal of Totladoh reservoir. The water released from RBC escape gate will flow through 32 Km drain and river channel to reach Kanhan intake well in another 72 hours, that is, by morning of February 10. To tide over crisis, NMC-OCW has planned for controlled supply during this period so that the adverse impact on water supply in North and East Nagpur areas could be minimised, stated the press release.

NMC-OCW started vigilance for elimination of any kind of obstruction (trench, temporary weir or diversion) and ensure normal flow of released water in this 32 Km pathway to reach Kanhan intake wells. At Kanhan WTP, river water was completely re-channelised towards the intake well and temporary weir was built to literally to ensure that river water did not flow downstream.
