Melamchi drinking water project to excavate tunnel through new technology

Kathmandu - Preparation has begun to devise a new technology to excavate tunnel to bring Yangri and Larke rivulets water to Kathmandu under the second phase of the much-awaited Melamchi Drinking Water Project. The diversion tunnel was excavated by Drilling, Blasting and Mucking (DBM) technology to divert raw water from Melamchi rivulet to Sundarijal outlet in the first phase.

As this method was more time-consuming with change in contractors, the Ministry of Drinking Water and Melamchi Drinking Water Development Committee have mooted the new technology. A cost estimation was also made to expedite the excavation work through DBM method to divert water from Yangri and Larke to the valley.
