At least 684-km pipeline has been installed so far under the Melamchi Water Supply Project.
The project has estimated to install a total 720-km of pipeline within 45 days but 684-km has been completed in the first phase so far.
The Kathmandu Upatyaka Khanepani Limited Project Implementation Directorate spokesperson Lila Prasad Dhakal said 69-km pipes have been installed out of 77-km under the main supply system.
Dhakal said the objective is to complete the task of laying down water supply pipelines by this July 16 under the first phase. Blacktopping of the sections of the roads which had been dug for installing the pipelines is also ongoing.
The Directorate itself is undertaking the blacktopping works on roads which are less than eight meters wide while the Road Division Office is blacktopping the roads more than eight meters wide, spokesman of the Department of Roads, Mukti Gautam said. He said valve chambers are being constructed on the main crossroads.
He said zebra crossings would be painted on these spots after the completion of all constructions by July 16 this year.
