JCM Project Design Document Form
A. Project description
A.1. Title of the JCM project
Energy Saving by Inverters for Distribution Pumps in Water Treatment Plant
A.2. General description of project and applied technologies and/or measures
The proposed JCM project aims to reduce CO2 emissions by introducing inverters to two
existing pumps (520kW and 272kW) which are owned by Phnom Penh Water Supply Authority.
The pumps with inverters are automatically controlled by the central monitoring system underthe best operational conditions. It can reduce the electricity consumption mostly derived fromthe Cambodia grid and leads to reduce CO2 emissions reduction at the water treatment plant.

A.6. Contribution from Japan
The proposed project was partially supported by the Ministry of the Environment, Japan(MOEJ) through the Financing Programme for JCM Model Projects, which provided financial
support of less than half of the initial investment for the projects in order to acquire JCMcredits.

methodology
Inverter(s) is installed to theexisting constant-speed pump(s) for

inwatertreatment plant.
The value of ECR of project pumpis always smaller than that ofreference pump at the same
operational load except when theoperational load is equal to one (1),which is demonstrated by equations
fixed ex ante or may bedemonstrated by equations ex postat the time of the first verification.
