Contractor reaches the site of Melamchi head works to clear debris

Kathmandu, Jan. 28

More than seven months after the intake of the Melamchi Water Supply Project (MWSP) was buried by debris brought by massive floods in the Melamchi River in Sindhupalchowk on 15 June 2021, works have begun to clear them.

Chinese contractor Sino Hydro has recently moved heavy equipment to the site and begun preparations to remove the debris from Friday, said Bashu Dev Paudyal, Executive Director of the Melamchi Water Supply Development Board.

According to him, the work will be executed in a way so that the water from the Melamchi River can be brought to the Kathmandu Valley by the Nepali New Year 2079, on 14 April 2022.

"In the first phase, the debris obstructing the water from channellising into the tunnel connecting the river and reservoir in Sundarijal of Kathmandu will be removed so that the water could be brought to the valley temporarily," said Paudyal, who returned from the site on Friday after making an observation of the preparation made by the contractor.

A temporary access road to the MWSP's head works was recently opened. The road was severely damaged by the torrential rains and subsequent landslides in monsoon last year. As the landslides jeopardised the human settlement above the road, the infrastructure could not be repaired or developed until the monsoon ceased.

The board has extended the deadline to complete the construction of the head works by mid-July this year as per the decision of a Cabinet meeting a couple of weeks ago, and directed the Sino Hydro to reach the site. The cost of the contract has also gone up by Rs. 320 million with the time overrun.

The cost variation is made for the contractor to clear the debris deposited at the head works.

Earlier in October 2019, the board had signed a contract with Sino Hydro with a mandate to complete the construction of head works in 15 months.

Paudyal said that the actual cost of the project could be calculated after clearing the debris as it is not known whether the head works constructed before the floods is intact.

According to the primary estimates made in August last year, the floods caused damages of about Rs. 2 billion to the project and the head works was buried about 15-20 metres down the debris.

The contractor had completed the construction of civil works of the head works, leaving only a small amount of hydro-mechanical and electrical works to complete.

The project had started distributing the water from the Melamchi River by the end of March 2021 while President Bidya Devi Bhandari had inaugurated the water distribution on April 2 last year.

The Rs. 36 billion project was conceptualised about five decades ago has completed about two decades after its commencement with multiple deadline extensions and cost overrun.

In the first phase, the national pride project will distribute 170 million litres of water a day – half of the total water that is being brought to the Kathmandu Valley from the Melamchi River in Sindhupalchok district via a 26.5 kilometre tunnel.

Another 340 million litres water would be brought to the valley from the Yangri and Larke rivers in Sindhupalchok through the same tunnel.

According to the board, water from the Yangri and Larke rivers could be brought to the valley within the next four years. The Yangri river is 9 km away from Melamchi head works and Larke is further 2 kilometres away from Yangri.

A 9-km-long tunnel will be built up to Yangri while the tunnel to Larke will have two parts, one for water and another for vehicular movement.
