Ranchi, August 31, 2026: Bihar and Jharkhand have taken a major step towards resolving their long-running dispute over the sharing of Son river water, with the two states signing a memorandum of understanding (MoU) in New Delhi on Monday.
The agreement was signed in the presence of Union Home and Cooperation Minister Amit Shah. Jharkhand Chief Minister Hemant Soren, Bihar Chief Minister Samrat Choudhary, Union Jal Shakti Minister C.R. Patil, the Bihar deputy chief minister, Union Home Secretary and senior officials from the Centre and both states attended the event.
The agreement is expected to improve the availability of water for irrigation and drinking purposes across large areas of both states.
Palamu and Garhwa among Jharkhand areas expected to benefit
For Jharkhand, the agreement is expected to improve water availability for irrigation and drinking purposes in Palamu, Garhwa and other concerned areas.
The potential benefits are particularly significant for rural and agriculture-dependent areas, where improved access to water could support farming and drinking-water requirements.
In Bihar, the areas expected to benefit include Bhojpur, Buxar, Rohtas, Kaimur, Aurangabad, Arwal, Gaya and Patna.
Amit Shah calls agreement an example of cooperative federalism
Amit Shah described the agreement as a major step towards resolving a long-pending water dispute in eastern India. He said the arrangement would help provide irrigation water to millions of farmers across rural areas of Bihar and Jharkhand while also improving access to drinking water.
Shah linked the agreement to Prime Minister Narendra Modi’s concept of “Team India” and cooperative federalism. He said differences between states could be addressed when governments work together through dialogue and in the national interest.
He also said the resolution of the Son water-sharing issue demonstrated that prolonged and complex inter-state disputes could be addressed through cooperation and continued discussions.
Hemant Soren, Samrat Choudhary thank Centre
Both Hemant Soren and Samrat Choudhary expressed their gratitude to Prime Minister Narendra Modi and Amit Shah for facilitating the resolution of the dispute.
Shah said efforts were also underway through the Inter-State Council to address water disputes and other issues related to water projects that have remained unresolved between states for decades.
He said four significant agreements concerning inter-state water disputes and water projects had been reached during the year so far.
The agreements cited by him included a July 7, 2026 settlement concerning pending payments related to the Narmada Award among Maharashtra, Gujarat, Rajasthan and Madhya Pradesh, a June 29 agreement between Rajasthan and Haryana concerning the Yamuna water project and a June 16 agreement involving Himachal Pradesh, Uttarakhand, Delhi, Uttar Pradesh, Haryana and Rajasthan on the implementation of the long-pending Kishau Multipurpose Dam Project.
The latest Son river agreement is expected to have particular significance for water availability in Palamu and Garhwa in Jharkhand, as well as several agriculture-dependent districts of Bihar.
