Sunkoshi Marin contract cancellation defers Madhesh irrigation dream

The cancelled item was the contract to build the Sunkoshi Marin project’s dam, powerhouse and associated structures. It was not the entire project. The cancellation matters because construction cannot move ahead under the current tender, even though the bidding process had reached its final financial stage.

Six companies had bid, but only three Chinese companies passed technical evaluation. Their financial proposals were due to be opened on Monday. The Department of Water Resources and Irrigation stopped that step and must now decide whether to invite fresh bids or use another route.

Former energy minister Kulman Ghising said restarting procurement could delay construction by six months to a year. The project already lost time after the previous contractor’s poor performance. Until a new contract is awarded, the dam, powerhouse and related works remain stalled, postponing planned irrigation and electricity benefits.

A multipurpose water-diversion project takes water from one river and directs it into another system for several purposes. In this case, the planned project would move Sunkoshi River water toward the Marin River basin. That matters because the diverted flow is intended to support farmland irrigation and generate hydropower.

Typically, a diversion system uses a dam or intake to control water, then carries it through a tunnel or other conveyance structure. The water can be released for irrigation and directed through a powerhouse, where its movement generates electricity. The article confirms the dam and powerhouse, but does not give the tunnel’s length, route or detailed operating design.

The project is therefore meant to link water management with energy production. Its planned benefits are year-round irrigation for 122,000 hectares and 31.07 megawatts of electricity. Those outcomes depend on completing the dam, diversion works and powerhouse.

The project’s intended scale is national rather than local. It is designed to provide year-round irrigation to 122,000 hectares of farmland in Nepal’s Tarai. Reliable water across that area could support farming in five districts and make the project important to agricultural planning.

The districts named are Bara, Rautahat, Sarlahi, Mahottari and Dhanusha. Alongside irrigation, the project is expected to generate 31.07 megawatts of electricity. This combined target explains why it is described as a multipurpose project and a delayed national pride project.

Those benefits remain planned, not delivered. The dam and powerhouse contract has been cancelled, and the next procurement step is undecided. Until construction resumes and the works are completed, the 122,000-hectare irrigation promise and the 31.07-megawatt power target remain uncertain.

If construction is delayed, farmers in the five targeted Tarai districts will continue waiting for the project’s planned year-round irrigation. The article does not quantify lost harvests, income reductions or specific crop effects. It does show that the project is intended to supply water to 122,000 hectares, so that benefit would remain unavailable.

The practical mechanism is straightforward: without completed diversion and irrigation works, Sunkoshi water cannot reach the planned farmland through the project. Farmers would therefore continue using whatever water sources and seasonal conditions are currently available. The article does not describe those existing arrangements in detail.

A further six-month-to-one-year delay would also postpone the project’s planned 31.07 megawatts of electricity. Longer uncertainty could prolong the gap between the promised agricultural benefits and their delivery. Authorities must first choose a procurement path and secure a new construction contract.

The Patel-Raman JV was supposed to complete the dam and related structures within four years and seven months. But after 60 percent of the contract period had elapsed, physical progress had not crossed 11 percent. The project terminated the agreement on November 11, 2025, after work failed to make adequate progress.

The contractor later challenged the termination in the Supreme Court. A temporary order initially blocked implementation and confiscation of bank guarantees, but the court revoked that order on February 9. The government recovered the Rs1.2 billion advance payment, while the Rs2.4 billion performance guarantee had not yet been collected.

The episode shows that large projects can face more than construction problems. Slow work, legal action, guarantees and blacklisting all affect the schedule. The joint venture was later blacklisted for three years. These complications can delay replacement procurement and increase uncertainty around public infrastructure.

Nepal’s water authorities now have to decide how to restart work on the dam and powerhouse. The project’s senior engineer said the Department of Water Resources and Irrigation could invite fresh bids or take another course of action. The article does not identify a specific alternative procurement method.

A fresh tender would mean preparing or confirming bidding documents, inviting companies, evaluating technical proposals and then examining financial offers. That would repeat a process that had already shortlisted three Chinese companies. Another route could only proceed under the applicable public procurement rules, but the article gives no details about what that route would be.

For now, financial proposals will not be opened. The department’s decision will determine whether the project loses another six months to a year, as former minister Ghising warned. A new contract must also address the earlier project’s slow progress and protect public funds and performance guarantees.

Dams and intake structures control river water and can create enough elevation or pressure for planned releases. Tunnels then carry water from the diversion point toward a powerhouse or irrigation area. Irrigation canals, pipes or outlets distribute the released water across farmland. This creates a managed supply rather than relying only on natural river timing.

For electricity, water moves through a powerhouse and turns turbines connected to generators. Afterward, the water can continue through the system or return to a river, depending on the design. For farming, gates and channels divide water among fields when crops need it. The article confirms a dam and powerhouse but does not provide the project’s technical layout.

The Sunkoshi Marin project combines these functions. It aims to provide year-round irrigation to 122,000 hectares and generate 31.07 megawatts. Those benefits depend on completing the diversion, dam, powerhouse and associated structures, which currently lack an active construction contract.
