Ganga water quality improving, claims Govt

At Gangotri, the sacred river is full of silt.


NEW DELHI: River cleaning and development is a continuous process and National Mission for Clean Ganga (NMCG) supplements the efforts of state government in cleaning of river by providing financial assistance to the state government. NMCG has sanctioned a total of 105 projects of sewerage infrastructure in Ganga basin states at an estimated cost of Rs 17,484.97 crores for river cleaning and Ganga rejuvenation. Out of these, 26 sewerage infrastructure projects have so far been completed resulting into creation of approximately 421 Million Litres per Day (MLD) additional STP capacity through construction / rehabilitation and approximately 2050 KM new sewer lines have been laid. Rest of the projects are under different stages of execution.

Top priority to inter-linking

The National Perspective Plan (NPP) was prepared by the then Ministry of Irrigation in August 1980 for transferring water from water surplus basins to water-deficit basins. Under the NPP, the National Water Development Agency (NWDA) identified 30 links (16 under Peninsular Component & 14 under Himalayan Component) for preparation of Feasibility Reports (FRs). The Pre-Feasibility Reports (PFRs) of all 30 links have been prepared and circulated to the concerned State Governments. After survey and investigations, FRs of 14 links under Peninsular Component and FRs of 2 links and draft FRs of 7 links (Indian portion) under Himalayan Component have been completed. Present status, States concerned, and benefits are given in Annexure. The Inter-Linking of River (ILR) programme has been taken up on high priority, says Union Minister of State for Water Resources, River Development and Ganga Rejuvenationi Arjun Ram Meghwal.

Four priority links under Peninsular Rivers Component have been identified for preparation of Detailed Project Report (DPR) viz; Ken-Betwa link project (KBLP) Phase –I & II, Damanganga-Pinjal link project, Par-Tapi-Narmada link project and Mahanadi Godavari link project. The preparation of DPR of a project is taken up after consent of concerned State Governments. DPRs of KBLP Phase-I & Phase-II, Damanganga-Pinjal link project and Par-Tapi-Narmada link project have been completed. The techno-economic clearance and various statutory clearances of the KBLP Phase-I have been accorded. Based on the request of Government of M.P., the DPRs of projects included under KBLP Phase-II viz., Lower Orr dam, Bina complex projects and Kotha barrage have been completed by NWDA/ Government of M.P. and submitted for techno-economical appraisal in Central Water Commission (CWC).

The techno-economic clearance of the Damanganga-Pinjal link project has been accorded subject to statutory clearances. The DPR of Par-Tapi-Narmada link project has been submitted for technical appraisal in CWC. The DPR of the Mahanadi – Godavari link could not be taken up as the Government of Odisha was not agreeable for Mahanadi – Godavari link, a mother link of 9 link system viz., Mahanadi – Godavari – Krishna – Pennar – Palar – Cauvery – Vaigai – Gundar linkage due to large submergence involved in Manibhadra Dam. Based on the suggestions of Govt. of Odisha, NWDA has prepared a preliminary revised proposal of Mahanadi- Godavari Link Project with reduced submergence and submitted to the Govt. of Odisha.

The estimated cost of these four projects for which DPRs have been completed is:

Sl.no. Name of the Project Estimated Cost (Rs. in crore)
at 2015-16 price level
1 Ken-Betwa Link Project(Phase-I) 18057
2 Ken-Betwa Link Project(Phase-II) 8594
3 Damanganga-Pinjal Link Project 3008
4 Par-Tapi-Narmada Link Project 10211

At the time of preparation of DPR of the individual river link projects, detailed Environmental Impact Assessment (EIA) studies as per Terms of Reference approved by Environmental Appraisal Committee (EAC) of Ministry of Environment and Forests & Climate Change are carried out. EIA study includes impacts on land environment, water resources and its quality, terrestrial ecology (flora, fauna, vegetation cover, wildlife), aquatic ecology (riverine ecology, fisheries), pollution due to noise during construction phase, impact on air quality, impact due to command area development, impacts on local services (like water supply, education, health care, community forests, impacts on business opportunities). All environmental impacts and issues arising out of the EIA studies are duly addressed in Environmental Management Plan which forms a part of DPR.

The impacts of individual ILR project on the human lives, environment, landmass, etc., are suitably addressed in the Environment Impact and Socio-economic impact Assessment studies which is part of the preparation of DPR.
