Objective and Purpose of the Assignment
  
The Ministry of Industry and Handicraft (MIH) is the executing agency for the Provincial Water Supply 
and Sanitation Project (PWSSP). A small team of national staff from MIH is currently responsible for the 
overall project coordination. Under the General Department of Potable Water Supply within MIH, and the 
General Department of Public Works within MPWT, two Project Management Units (PMUs) have been 
established for project implementation, and will be assisted by the Project Implementation Assistance 
Consultants (PIAC) for technical, safeguards, accounting and management aspects of the project, as well 
as provide support to the four PIUs with project implementation. The PIUs have been established in the 
four project towns and are responsible for monitoring and reporting monthly to the PMU on project 
progress, contract supervision, liaison, implementation of training programs, and coordinating with 
other provincial agencies.

Currently, the overall project implementation progress is slow, and the project is rated as an ‘actual 
problem’. The EA’s (MIH) team is new and not fully familiar with international practices in water supply 
systems. PIAC will be responsible for preparing the detailed engineering designs (DEDs) for the river 
intakes, transmission mains, water treatment plants (WTPs), and distribution networks in Battambang and 
Kampong Cham. To strengthen MIH’s capacity and to assist with PMU to review the technical deliverables 
including detailed engineering designs and providing technical support to the project in general, there 
is a need to recruit an international water supply expert.

Scope of Work
  
The Consultant will directly support the MIH’s Project Director and his team on technical matters 
related to water supply for implementation of MIH projects, including PWSSP. The Consultant will assist 
MIH in reviewing the detailed engineering designs (DEDs) for the river intakes, transmission mains, 
water treatment plants (WTPs), and distribution networks in Battambang and Kampong Cham prepared by 
PIAC, and any other technical tasks related to water supply under the MIH projects.

Detailed Tasks and/or Expected Output
  
S/he will carry out, the following main tasks, including but not limited to:
(i)	Assist MIH in reviewing the detailed engineering designs (DEDs) for the river intakes, transmission 
mains, water treatment plants (WTPs), and distribution networks in Battambang and Kampong Cham prepared 
by PIAC,
(ii)	Assist MIH in reviewing detailed hydraulic designs, pump working curve calculations, drawings, 
bills of quantities, and technical specifications for the Intake pumping stations, WTPs for Battambang 
and Kampong Cham, as required.
(iii)	Review the specific design report that includes DED for the proposed design and treatment process, 
specifically on expected flow and water quality, screening equipment and functionality, disposal of 
screenings and process sludges, use of sand filters, coagulation flocculation, disinfection, etc.
(iv)	Review specific design review reports that include major nodes of proposed network system.
(v)	Review designs of pipe diameters, routes, materials of construction, pipe support materials, bedding 
and cover, and concrete quality.
(vi)	Review designs of equipment support plates, noise protection and ventilation.
(vii)	Ensure that designs are appropriate and represent good practice.
(viii)	Review the proposed selection of materials as per national standards for water transmission and 
distribution, taking into account the local conditions, in particular pipe corrosion and durability, and 
equipment robustness and repairability.
(ix)	Review the proposed selection of materials/chemicals for water treatment taking into account the 
local conditions.
(x)	Review specifications, cost estimates, and bidding documents for other water supply works and goods 
packages, if required.
(xi)	Review the manual for successful operation of both treatment plants to use by the PWWs.

Minimum Qualification Requirements
  
Twenty (20) years of relevant professional experience since graduation. Fifteen (15) years of experience 
in the design and installation of water intakes, water treatment systems and water distribution 
networks. Five (5) years of experience in developing countries, preferably in Southeast Asia. Experience 
in the operation and maintenance of water and sanitation facilities is preferred. Previous experience in 
projects financed by multilateral development agencies is preferred.
