Centre steps up efforts to clean Ganga tributaries

New Delhi : The Union Water Resources Ministry has stepped up attention towards Ganga's tributaries, sanctioning projects worth over Rs 840 crore in Uttar Pradesh and West Bengal recently even as a major Rs 908 crore concession contract has been signed with Shapoorji Pallonji & Company Ltd for boosting the sewage treatment infrastructure at Kanpur.

The Ministry, through the National Mission for Clean Ganga (NMCG), is taking up 26 projects on some major Ganga tributaries including Yamuna, Saryu, Ram Ganga, Gomti, Kali, Kosi, Gandak, Damodar and Rispana-Bindal.

In the recent meeting of its executive committee, NMCG approved projects worth Rs 841 crore in Uttar Pradesh and West Bengal, taking up the sanctioned cost of all sewerage projects on tributaries to Rs 5735 crore.

As many as 30 sewerage projects have already been sanctioned on tributaries in Uttarakhand, Uttar Pradesh, Bihar, Jharkhand, West Bengal, Haryana, Delhi and Himachal Pradesh.

The NMCG also recently approved a sewage treatment plant (STP) on Ganga in Bihar at a cost of Rs 41.36 crore

For Uttar Pradesh, projects have been approved in Bareilly, Muzaffarnagar and Budhana at a total cost of Rs 551.94 crore.

For Bareilly, 14 interception & diversion works (I&D) and four STPs with 63 million litre per day (MLD) capacity have been approved. The town lies entirely on the Ganga plains and Ramganga, one of its major tributaries, flows near it, along with other rivers including Bahgul, Shankh, Devrania, Nakatia as well as Kailasi.

There are 13 major drains in the town, having cumulative discharge of 41 MLD in the Nakatiya River. Choubari nala has 18.25 MLD discharge and Airforce nala has a discharge of 1 MLD. A decentralized STP has been proposed for this area.

There are five nalas from the central zone, for which three projects are ongoing under the AMRUT scheme. The STP capacity is 35 MLD for the central zone. The remaining interventions have been proposed in these projects, while integrating the ongoing schemes.

The Muzaffarnagar project was also been given the approval. It includes eight I&D structures and a 22-MLD new STP besides and other works including O&M for 15 years. There are 10 major drains in the town, out of which three are under East zone and the remaining seven under West zone.

The cumulative present discharge of the East zone drains is 22.82 MLD while that of West zone drains is 53.52 MLD

The NMCG has also approved I&D and sewage treatment plant at Budhana, which includes construction of a new 10-MLD STP, three I&D structures and allied works, along-with operation & maintenance cost for 15 years.

There are three drains in the town which carry untreated wastewater from houses and establishment. All the three drains - Dobhi ghat, Sabzi Mandi & Shamshaan ghat - have a cumulative discharge of 10.07 MLD, which is directly falling into the Kali River without any treatment.

Interception & diversion network for the drains falling in Damodar River in West Bengal, including pumping stations and STPs under Durgapur Municipality has been approved at a total project cost of Rs 287.53 crore. This project includes two STPs of 25 MLD each and one STP of 30 MLD capacity, network laying of 5.73 KM with O&M cost for 15 years.

There is no centralized sewerage system in the town and it is currently facing a serious problem in sanitation. The entire wastewater from upper and lower part of the municipal town flows into the Damodar River through surface drains and then into the Hoogly. All the drains falling into the Damodar River need to be intercepted, and then diverted to proposed lift stations (LS), main pumping stations (MPS) and the proposed STPs.

The NMCG has also approved a I&D and STP project for Maner in Bihar. The project includes three I&D structures for the drains, construction of a 6.5-MLD STP, UV disinfection, SCADA online monitoring system and necessary ancillary infrastructures.

On implementation of the project, there will be no discharge of untreated sewage from Maner into Ganga.

An action plan is also being worked out for use of reclaimed water. In line with the holistic approach adopted by NMCG, treated wastewater is proposed to be used either in agriculture or in the industrial sector. The states have been asked to work out proposals for re-use in each project.

Nine of the 10 worst global risks are linked to water

Water is one of the world’s gravest risks, according to the Global Risks Report published earlier this week at the World Economic Forum in Davos. And the situation is actually worse than it might seem at first glance.
