PLAN FOR SOFT COMPONENT

1. Background for Planning Soft Component

The Project aims at securing safe and stable water supply through development of new water

source (new groundwater wells), construction of settling tank for turbidity reduction for eliminating

turbid water in the network during and after heavy rain, construction of new water reservoirs and

establishment of block distribution system.

SIWA, management authority for conducting operation and maintenance of the facilities to be

constructed in the Project, has been doing operation and maintenance of the existing water supply

facilities. However, they are facing with the following issues:

(1) Establishment of Daily Control System for Water Quality

SIWA has basic skills for water quality analysis. However, they do not have water quality

control system including daily water quality monitoring system and communication system when

water quality exceeds its standard. They are required to establish water quality control system

consisting of defining water quality items to be analyzed/frequency of analysis/sampling points,

keeping and sorting-out of data, diagnosis for abnormal cases, procedures for taking actions in case of

emergency, etc.

(2) Control of Water Distribution Volume and Water Pressure in Water Supply System

Since SIWA has not conducted water distribution control according to the water distribution

volume and water pressure, a part of the distribution districts are suffering from extremely low

pressure. For coping with this problem, block distribution system will be adopted for stabilizing water

distribution volume and water pressure.

In order for SIWA to implement an appropriate control for water distribution volume and water

pressure in the service areas, it is required for SIWA to do water distribution and water pressure

control in each block of distribution districts.

(3) Economical Operation for Facilities

Since rising price of electric power is affecting financially for SIWA’s management, economical

operation of facilities based on water demand and water quality is required to minimize the cost for

operating pump equipment and chlorine disinfection equipment.

Furthermore, SIWA has no experience with operation and maintenance for settling basin for

turbidity reduction. Issues mentioned in items 1) to 3) above are related each other and they can be

A5-2

summarized as three issues of “understanding of water supply system”, “learning method for operation

and maintenance of water supply system” and “learning method for taking record, sorting out and

utilizing of water quality and quantity data”.

Technical assistance to cope with the above-mentioned issues is required to SIWA for at least

securing sustainability of outputs from the Project.

2. Objectives of the Soft Component

Among SIWA staff, 15 staff of water supply section of engineering service department shall

achieve the following objectives:

Understanding water supply system

Conducting operation and maintenance for water supply system

Taking record, sorting out and utilizing of water quality and quantity data

3. Outputs from the Soft Component

Outputs from the Soft Component are as follows:

(1) Understanding of water supply system

Water supply system from borehole facilities to water transmission pump station and

distribution reservoir is understood.

Treatment process and functions for settling basin for turbidity reduction is learned.

(2) Learning method for operation and maintenance for water supply system

Necessity for stopping water intake based on water quality of raw water can be judged.

Monitoring and control based on water quality/quantity of raw water and water quality

/water demand of distributed water can be conducted.

Injection of disinfection agent can be done properly.

Monitoring and control for water quality and quantity of distributed water can be conducted.

(3) Learning method for taking record, sorting-out and utilizing of water quality and quantity

Taking record, sorting-out and utilizing of water quality and quantity of raw water into

settling basin for turbidity reduction can be conducted.

Taking record and sorting-out of data for water intake, water transmission and water

distribution volumes can be conducted. Then, based on those data, demand projection of

water distributed can be conducted and plans for required water transmission volume and

operating control of water distribution can be formulated.

Taking record, sorting-out and utilizing of data for water quality and water pressure of

A5-3

distributed water can be done.

4. Methods for Confirming Achievement of Outputs

Achievement level of outputs from the Soft Component shall be examined by confirming

acquirement level of knowledge and improvement level of routine works by utilizing acquired

knowledge.

9. Responsibilities of the Implementing Agency in the Recipient Country

(1) Practicability for Implementation

Since SIWA has much desire for technical transfer of three (3) objectives in the Soft Component

to SIWA staff, practicability for implementation is considered high.

However, in order to achieve those objectives of the Soft Component, institutional and financial

conditions of SIWA have to be guaranteed.

Recently, SIWA have been recruiting new staff for operation and maintenance (O&M) and it is

expected that organization for O&M should be strengthened by the completion of facility construction

work for the Project. Also, financial situation is relatively in good condition with surplus in the

balance in the fiscal year of 2007 and there are no problems in the financial aspect for implementation

of the Soft Component. Therefore, it is considered that SIWA is capable of bearing necessary

undertakings by the Solomon Islands side for implementation of the Soft Component.

(2) Impeding Factors and Required Actions by SIWA

Although no impeding factors in training items are expected, trainees for the Soft Component

should satisfy with the following requirements. In order to meet these requirements, SIWA is required

to make those trainees acquire the necessary skills for the training. Also, key personnel for O&M

A5-9

should be trained for all the items of the Soft Component.

Acquiring basic operation method of computer

Acquiring operation method of operating system (MS-Excel and MS-Word)

Securing enough time necessary for class-room training and practical training (4 hours a day)

SIWA is required to prepare the following for smooth implementation of the Soft Component:

Personal computers (4 units), Software (1 set), Printers (1 unit)

Training place and spare (one room in SIWA office)

In addition, in the training for “Leaning method for taking record, sorting out and utilizing of

water quality and quantity data, SIWA is required to prepare hardware such as personal computers, etc.

before commencement of the training. For this reason, SIWA is requested to prepare for the training,

working closely with the Japanese consultant who will provide application software for data process.

For the above-mentioned hardware and software, it has been confirmed during the field survey

of the basic design study that all the necessary items are ready in SIWA and will be utilized for the

training of the Soft Component.
