Government of India formulated the National Perspective Plan (NPP) for Inter-Basin Water Transfer and 30 Interlinking of Rivers (ILR) Projects were identified under NPP (16 link projects under the Peninsular component and 14 link projects under the Himalayan component). National Water Development Agency (NWDA) has been entrusted with the work of ILR. The present status of all 30 ILR projects is at Annexure.

The Ken-Betwa Link Project (KBLP) is the only priority link project under the NPP that has entered the implementation stage. The project, with an estimated cost of ₹44,605 crore, is envisaged to provide irrigation to about 11.88 lakh hectares, drinking water supply to about 62 lakh people, 103 MW of hydropower and 27 MW of solar power.

In addition, the Polavaram Irrigation Project (PIP), which incorporates the Godavari (Polavaram)–Krishna (Vijayawada) link, stands classified as a National Project and is executed by the Government of Andhra Pradesh and Polavaram Project Authority (PPA). The project envisages irrigation to about 7.2 lakh acres and stabilization of 23.5 lakh acres in the Godavari and Krishna delta systems, diversion of 80 TMC of Godavari water to the Krishna basin, drinking and industrial water supply including to Visakhapatnam, domestic water supply to about 28.5 lakh population in 611 villages, and hydropower generation of 960 MW. The Polavaram Irrigation Project has received cumulative Central Assistance of ₹20,658 crore.

An Environmental Impact Assessment (EIA) forms part of the preparation of Feasibility Reports (FRs) and Detailed Project Reports (DPRs) for every Interlinking of Rivers (ILR) project, with assessment of environmental and socio‑economic impacts. For the Ken–Betwa Link Project, a comprehensive EIA has been completed along with an Integrated Landscape Management Plan (ILMP), which outlines measures relating to catchment‑area treatment, landscape‑level ecological management, biodiversity conservation, command‑area development and long‑term monitoring of environmental parameters. For all ILR projects, including the Ken–Betwa Link Project, Land Acquisition and Rehabilitation & Resettlement (R&R) components stand included in the sanctioned project structure, and project execution conforms to applicable environmental, forest‑clearance and R&R provisions.

* Due to pending consensus on Manibhadra and Inchampalli dams, Phase-I of the Project to divert unutilized waters of Godavari River was carried out, and DPR of Godavari (Inchampalli) – Krishna (Nagarjunasagar) - Pennar (Somasila) – Cauvery (Grand Anicut) link projects (combined) called the Godavari-Cauvery link was completed. The report has further been updated, terminating the link canal at Manimukhta nadi, a Tributary of the Vellar River flowing adjacent to the Cauvery basin.

@@ Bedti – Varda Link - DPR was prepared directly after preparation of its PFR; no FR was prepared.

@ Godavari (Polavaram) - Krishna (Vijayawada) Link- the project has been completed by the Govt. of Andhra Pradesh and Polavaram Project Authority.

** Netravati – Hemavati link: Further studies not taken up after PFR preparation since, after implementation of the Yettinahole project by the Govt. of Karnataka, no surplus water is available in Netravati basin for diversion through this link.

HIMALAYAN COMPONENT
