Objective and Purpose of the Assignment

The National Water Supply and Drainage Board intends to call financial proposals (remuneration and per diem) from the individual consultants to provide expert services to carry out pre-feasibility studies for the construction of lower Pali Aru Reservoir.

The study of lower Pali aru reservoir is proposed to carry out in two phases as follows;

Phase 1: Pre-Feasibility Study

In the Phase 1, the Pre-Feasibility study is proposed to carry out by individual consultants. This study is to carry out a detailed hydrological study and geotechnical study in order to identify a location to construct a reservoir across lower Pali aru and assessing the capacity of reservoir with a conceptual design of dam and spill way structure and recommendation for further studies.

Phase 2: Feasibility Study

In the Phase 2, the detailed study shall be carried out based on outcome of Phase 1 pre-feasibility study and submit the necessary documents to construct a reservoir and water treatment plant. This study shall be carried out in detail with respect to technical, environmental and social aspects and produce the feasibility report, detail design reports, working drawings and bid document.

This Terms of Reference (TOR) below outline the scope of the work, responsibilities of individual consultants to carry out the Pre-Feasibility Study to achieve the tasks and to produce the deliverable such as the pre-feasibility report with conceptual design, tentative cost estimate within the stipulated period of five months.

In this Phase 1 – Pre Feasibility Study four individual consultants are proposed to involve to develop the Pre-Feasibility Study Report. One of the individual consultant with the capacity of Water Resources Engineering shall act as Team Leader and the team shall comprise of Hydrologist, Geo technical Engineer and Environmental Specialist. Further above mentioned expert team shall assist with Engineering Assistant, GIS specialist, CAD person and Secretary.

The detailed scope of the study, output of the work and facilities to be provided by the Client are described in sections below. The detailed scope of the study and output of the work of other experts are described in Annex 1.

Objectives of the Consultancy Service under Phase 1

The objectives of the Consultancy Service in respect of this pre-feasibility study is to formulate a composite project proposal to optimize the water resource under lower Pali aru river basin by constructing a reservoir to meet the demand taking into consideration of technical, social and environmental aspects with necessary documents required for next phase of detailed study.

Accordingly, it is proposed to engage the service of individual consultant for a pre-feasibility study of proposed Pali aru reservoir.
