Frequent Power Tripping’s at Kanhan & Gorewada WTP’s hit water supply


Nagpur: Water supply affected in North, East Nagpur Why? We are receiving low pressure water Supply, It is taking almost an hour to fill a small bucket only? Why u are not supplying water with full pressure to our locality? These are some of frequently asked queries, from hundreds of others coming up at OCW Call Centre, compliant centres at Zonal offices of NMC-OCW every day.

Most of the times complainant receive replies like ‘Kanhan trip hua hain’ or ‘Gorewada Trip Hua Hain” or Pench IV Water Treatment Plant (WTP) Trip Hua hain…..

As per statistics at 240 MLD capacity Kanhan WTP , there have been almost 28 times power trip (total 12 hour) in last two months (since March 1) , especially at Juni Kamptee Jackwell

Likewise.. as per records at Gorewada based Pench- I, Pench-II & Pench III water treatment plants almost 7 times power trippings reported which is almost 2.45 hour while Pench IV was affected for an hour in the month of April.

Power tripping at Kanhan WTP had majorly affected East, North and parts of South Nagpur areas during and after tripping hours, while trippings at Navegaon-Khairi pumping house and Gorewada WTP’s (Pench I, II, III & Old Gorewada) affected water supply of West, Central, South- West and part of South Nagpur localities.

Citizens of Nagpur especially from areas of

Kanhan WTP: Nehru Nagar zone, Lakadganj zone, Partial Satranjipura zone, Partial Aashi Nagar Zone based on Kanhan WTP.

Pench I, II, III: Laxmi Nagar New ESR, Gayatri Nagar ESR, Pratap Nagar ESR, Trimurti Nagar ESR, Jaitala ESR, Takliseem ESR, Ramnagar ESR, Chinchbhavan ESR, Buldi Fort 1 & 2 GSR , Boriyapura ESR, Killa Mahal ESR, Riffle, Futala ESR’s

Pench IV: GH-Kanhan ESR, Nari ESR, Jaripatka ESR , Indora ESR, Civil Lines DT, Indora DT, Omkar Nagar 1 & 2 ESR’s, Shree Nagar DT & Mhalgi Nagar ESR were deprived from precious potable water supply or compelled to live with either restricted, low pressure or no water supply in many areas. Their Taps received water with low pressure
Technical experts in industry informed that frequent power tripping is the main reason of air interruption in the system which takes more time to evacuate. Normally it takes about 25 minutes to fill one ESR (Over head tank of 22.70 lakh liter capacity). Though the tripping period in WTP’s was from 5 minutes to 10, 15 or 20 minutes duration but due to tripping, the water levels of ESR’s which were under supply at that period was reached its lowest levels and supply was badly affected in the following areas and its post effects remains on those areas whose supply period is after the tripping period i.e in evening hours after 6 pm.

Pllowing this power trippings in last two months total loss of 213 Million Liters production was reported from all WTP’s ( 66.55 million liter in March, 125.96 million liters in April and 20.50 million liters till May 7)

As per experts, normally after a small tripping of even a 5 minutes and after restart of pumping to reach the required flow rate of water from the feeder main pipelines it will take more than two & half hours period after the pumping was restarted.

It may be mentioned here due to such power tripping’s citizens face problems and are compelled to receive either restricted, low pressure or no water supply, however NMC-OCW technical experts always try hard to manage the show to provide adequate water supply to citizens after tripping incidences.

NMC-OCW has thanked all citizens for their co-operations during such difficult period and has further appealed to co-operate in future. The inconvenience caused in water supply due to such power tripping in last two months is also highly regretted.
