Objective and Purpose of the Assignment
The Galle Water Supply System is facing significant challenges related to high Non-Revenue Water (NRW),
operational inefficiencies, and limited water resources. To address these issues, the National Water
Supply and Drainage Board (NWSDB) is implementing a NRW Reduction and Management Project in Galle under
a Performance-Based Contract (PBC) and Private Sector Participation (PSP) model (the Project).
The Asian Development Bank (ADB) is providing Transaction Advisory Services (TAS) through the Office of
Markets Development and PPP (OMDP), which engaged an International NRW Technical Expert. Additionally,
there are three (3) embedded Engineers already deployed under TA sources to provide on-ground technical
support.
To strengthen project delivery, OMDP intends to engage a National NRW Technical Consultant (the
Consultant) to provide comprehensive technical consultancy services, working in close collaboration with
the International NRW Technical Expert and embedded Engineers and under the guidance of OMDP.
Scope of Work
The primary objective of this consultancy is to provide specialized engineering consultancy services,
including technical knowledge, advisory support, and capacity strengthening. The Consultant will work
closely with the International NRW Technical Expert, embedded Engineers and OMDP to ensure effective
project preparation and tendering of the Project.
Detailed Tasks and/or Expected Output
The Consultant will report directly to OMDP Leader and will work collaboratively with the embedded
Engineers, who are under the supervision of OMDP. The consultancy services include, but are not limited
to, the following:
