Water supply to Kathmandu Valley expected to resume from January 15
KATHMANDU, Jan 13: The eagerly anticipated water supply from the Melamchi Water Supply Project which had been blocked due to floods and landslides in 2021 is set to resume in Kathmandu from January 15.
The transfer of Melamchi water to Kathmandu has already commenced from Wednesday evening following necessary repairs in the affected area.
The saga of the Melamchi project, which was hailed as a beacon of hope for solving the water crisis that long plagued the Kathmandu Valley, spans three decades, punctuated by intermittent progress and sustained setbacks, ranging from pauses triggered by natural calamities to local opposition.
Despite facing setbacks and the vulnerability of the headworks area to floods and landslides, the project is now poised to fulfill its ultimate purpose of satiating the valley's long-standing thirst.
Matthäus Rest's paper on the Melamchi project reveals that in 1972, a comprehensive water supply potential study identified 30 potential schemes to address Kathmandu's drinking water needs. Following extensive deliberations, the Melamchi option was selected among various alternatives in the early 1980s, despite other choices presenting significantly fewer engineering challenges.
The promise to address Kathmandu's water needs is finally going to be fulfilled. Padma Bahadur Kunwar, senior divisional engineer of Melamchi Water Supply Development Board, said that water has been diverted to Kathmandu since Wednesday evening as per the agreement between Melamchi Water Supply Development Board and the construction company Sinohydro on 19th December to bring Melamchi river’s water to Kathmandu within 28 days.
He said, "The water of Melamchi has been diverted to Kathmandu in response to the demand of the builders. Since there is half of the water in the 27 km long tunnel, the water from the Melamchi river will reach the water treatment center at Sundarijal in Kathmandu in the next four days." It is reported that Kathmandu Upatyaka Khanepani Limited (KUKL) is preparing to distribute water from Melamchi to Kathmandu valley residents from January 15.
Zakki Ahmed Ansari, project director of Melamchi Water Supply Development Board, said that the project will supply 170 million liters of water to Kathmandu on a daily basis. Senior Divisional Engineer Kunwar said that the project has repaired Gate No 21, Gate No 9 and Gate No 1 at the source of the river in Ambathan and started sending water to Kathmandu from Wednesday evening.
According to him, the contractors mobilized more than 45 workers and necessary machines daily to rebuild the structures damaged by the flood. Water Supply Minister Mahindra Raya Yadav had earlier announced that Melamchi water will be brought to Kathmandu by the end of December. Minister Yadav also carried out on-site monitoring three times to bring water from Melamchi to Kathmandu immediately.
Melamchi Water Supply Project spokesperson Rajendra Pant said that water has been released to the tunnel from the site of the dam to clean the tunnel.
According to him, the turbid water being cleaned from the tunnel will be extracted through the audit tunnels in Ambathan, Gyalthum, and Sundarijal.
He said that once the water sent to the tunnel becomes clear, it will be directed to Kathmandu in its entirety.
However, he said that determining the exact duration for cleaning the tunnel and establishing a regular water supply schedule is currently not feasible.
Minister Yadav's personal secretary Tanka Dhamala said that Water Supply Secretary Suresh Acharya and Melamchi Water Supply Development Board's project director Ansari are actively working to resume the water supply to Kathmandu that had come to a halt due to floods.
