VA Tech WABAG has strengthened its global footprint once again by securing a significant repeat order from the Melamchi Water Supply Development Board (MWSDB) in Nepal. The new contract covers the Design, Build and Operate (DBO) development of the Sundarijal Water Treatment Plant, a large-scale project designed to deliver 255 million litres of clean drinking water per day to the Kathmandu Valley. The project is funded by the Asian Development Bank (ADB), reflecting its importance to the region’s long-term water security.
The scope includes full Engineering, Procurement and Construction over a period of 36 months, followed by five years of comprehensive Operation and Maintenance services. This structure highlights WABAG’s ability to deliver not just infrastructure, but long-term lifecycle support for essential water systems. The new plant will be built next to the existing Melamchi facility, which WABAG successfully executed in 2017. Once operational, it will process water sourced from the Melamchi, Yangri and Larke rivers, ensuring compliance with Nepal’s National Drinking Water Quality Standards.
This project arrives at a critical moment for Kathmandu, where rising demand and rapid urban expansion continue to put pressure on existing water resources. The large order category indicates an estimated project value between USD 30 million and USD 75 million, underscoring the scale and importance of the undertaking.
