Electrical Distribution Line Route Survey
1. Objective and Procedure of the Survey
An electrical distribution line route survey (hereinafter referred to as “the Survey”) was carried out in order to study the possibility of supplying power to planned pump houses from the existing electricity grid (the Grid).
The procedure of the Survey was as follows:
1) Data collection from ELECTROGAZ, 2) Mapping of the existing Grid and planned pump station on existing maps 3) Site survey around each planned pump station, 4) Planning of distribution line route along the planned distribution line, and 5) Site survey and study of the planned distribution line route.
GPS was used to conduct the Survey and the surveyed route was plotted on the map.
2. Survey Locations
The Governments requested 17 locations to be surveyed on the original plan. Five of the locations were removed from the plan based on an initial site study. One new location was added to the plan during the study. In total, the 13 locations listed below were surveyed with total length of 85 km.

3. Survey Result and Evaluation
As the survey result in the table below show, all except one location were 2-10 km away from the existing Grid. The purpose of the Survey was to study the possibility of connecting distribution line (low voltage: 0.4 kV) from the existing Grid to pump stations; however, ELECTROGAZ insists that all new power supply lines must be medium voltage (30 kV) and a transformer installed near the planned pump station. Therefore, it is obvious that a transmission line shall be applied for all sites.
From the data collection, it was discovered that the construction cost of a general type of transmission line is about US$5.3 million per kilometer and distribution line is about US$2.8 million per kilometer.

Rukira 13 Rwanyakagezi 9,357 9,298 59 Note: locations shadowed were removed from the plan based on the result of the basic design study.
Besides the result mentioned above, the following two issues were discovered:
It is anticipated that a commercial power supply would be subject to frequent power interruption for up to 12 hours a day on average over large parts of the former Kibungo Province, except in the vicinity of Rwamagana town. This would disrupt the water supply. This situation is forecast to continue because even though ELECTROGAZ plans to improve the situation by the latter part of the year 2007, the plan is likely to be delayed.
The running cost for commercial power supplies is 110% of that of a diesel generator because the electricity price of Frw 112/kwh was raised on the 1st of December 2005 from Frw 81.26/kwh.
Appendix-5.1
A5.1-3
Based on the results above, the power supply from the existing Grid is summarized as 1) rising construction cost, 2) fragile power supply, 3) little advantage in running-cost compared to a diesel-engine-powered generator. Therefore, it was concluded that a power supply from the existing Grid should not be supplied at all locations of the planned pump houses.
Appendix-5.2
A5.2-1
Social Survey Results
1 Objective and Procedure of Social Survey
A social survey was carried out in order to understand the socio-economic and living condition of the people living in the project site so that a sustainable scheme should be constructed under this study. Major objectives of the social survey were set as follows:
(1) to collect quantitative and related information of the present socio-economic situation, water use and hygiene condition;
(2) to collect quantitative information on people’s awareness on their need to participate in the project activities; and,
(3) to collect quantitative information of the present living condition of vulnerable people in the project area. The social survey was executed by means of a sub-contract with a local consultant from the 12th October to 5th November, 2005. The total number of samples for the social survey was 150 for the 10 districts of the project area, including representatives of the community, women group leaders and vulnerable people. The sample of each category was randomly selected from the community in the project area. There were 71 representatives of the communities, 46 women group leaders and 33 vulnerable people selected. An interview method was employed to collect the information from the sampled households employing local surveyors in each district. Prior to the social survey, two days training program for interviewers was held by the local consultant.
2 Main Findings from Social Survey
2.1 Major Industry in the Project Area The social survey revealed that the major industry in the project area was agriculture, with 94% of interviewees engaging in agricultural activities as shown in Figure 2.1. July was identified as the month of highest income because of the host harvest season. On the other hand October or November was identified as the month of lowest income due to no harvest. This indicates that the income of people in the project area fluctuates and is insecure throughout the year.

Figure 2.2 Present Water Source
It was found that rain water use during the rainy season increased dramatically, compared with almost no use during the dry season. It appears that people collect rainfall water using roof catchment or jerry can to minimize drawing water from the water source located at the lower side of the valley. Some people take water from puddles near their houses after rainfall.
Regarding people’s awareness on the quality of present water sources, most of the people were not satisfied with the present quality. The result of the survey on water quality is shown in the following table.

It is supposed that people have no choice but to use such unsatisfactory water sources due to a lack of clean water near their houses.
2.3 Necessary Time for Water Drawing
According to the result of the necessary time for water drawing, most people spend time less than one hour. During the rainy season, the time equal to or less than 30 minutes increases because some other water sources may appear near the house.

Figure 2.4 Bathing Time Figure 2.5 Common Diseases
On the other hand, the common diseases in the project area are shown in Figure 2.5. Malaria is the most common followed by diarrhea. Most people live on hill tops, but they usually travel down to lower land to fetch water, increasing their exposure to malaria. People have chronic diarrhea due to drinking unsanitary water and living under poor hygiene conditions. In addition many children have skin disease.
According to the social survey, although local people have an awareness of the benefit of boiling water before drinking, many drink unboiled water due to a lack of fire wood, being thirsty after working, or a lack of cooking utensils. Some people misunderstand
Appendix-5.2
A5.2-4
that settling water is a form of treatment. Demand for clean water is very high in the project area.
3 Vulnerable People in the Project Area
Elderly persons without relatives, widows, orphans and handicapped are normally defined as vulnerable people in Rwanda. They live in the same village as ordinary people. According to the information of each district in the project area, 10-25% of the population belongs to the vulnerable group. The further from the center of the village, the more vulnerable people there are.
Many vulnerable people live under the support of domestic aid organization and/or municipality. Ordinary support from the municipality is payment of social insurance, supply of housing, and payment of the water tariff. Elementary school in Rwanda is compulsory education and no education fee is charged for it. But many children lose the opportunity to go to school because they must work for the family business, take care of livestock, or fetch water.
4 Willingness to Pay
According to the social survey on willingness to pay, 88% of people showed a willingness to pay for water. But the remaining 12% did not show a willingness to pay. On the other hand, 42% of people only showed willingness to participate in operation and maintenance activity by themselves. The social survey suggests that many people have a high willingness to pay for water but low willingness to participate.

Figure 4.2 Willingness to Pay in Each District and Social Background
It is indicated that people show a high willingness to pay in the project area. But awareness on the beneficiary payment principle for operation and maintenance should be accelerated through the project. On the other hand, water taps with motorized pump was selected as the most preferable type of water supply facility. The second is public tap with gravity distribution and third is hand pump. Demand for a piped water supply system is very high because people can fetch water near their house and intend to be free from previous water drawing activity. The expected amount of payment per jerry can (20L) is mainly equal to or less than Frw 10. The average expected amount per 20 liters for hand pump, motor pump and gravity distribution is Frw 5, Frw 7.8 and Frw 9.4 respectively.

The rate of no payment for hand pump was higher than for the other types of facilities. Acceleration of people awareness on the beneficiary payment principle is required to ensure sustainable water supply activity in parallel with education on the necessity for appropriate operation and maintenance.
5 Payable Amount
According to the social survey, the monthly income of most households was below the poverty line which has been defined as daily income of 1 US$. The income gap between vulnerable group and others was almost 2.8 times.

According to the site survey, most local people in the project area are self-sufficient. The above said monthly income may be pointed out as a secondary income. The payable amount for water use shall be decided in consideration of willingness to pay instead of the common index of 4% of disposable income. Payable amount using the common index is estimated at Frw 15 /day/household. Project under such low payable amount will be terminated soon.
6 Proposed Water Charge
As a result of maintenance, the cost estimate for necessary operation and maintenance in each district is shown in the attached table. The operation and maintenance cost per capita per day is estimated to be in the range of Frw 5–10 per jerry can.
A constant water rate should be applied to each scheme in the same district for purposes of equity. The proposed water rate except for hand pump schemes and gravity piped water schems is shown in the following table.

Note: The above rates are guideline values for estimate purpose and vary according to the local conditions.
At the commencement of the project, the water rate shall be set as low as possible to stabilize water use at the constructed facilities. Proposed water rate is set at Frw 10 per

jerry can (20 liters) without any subsidy for the vulnerable group. The water rate shall be gradually increased to Frw 15~20 per jerry can after popularization of water use because of financial reinforcement for periodical improvement of facilities. For economic support of the vulnerable group, it is proposed that vulnerable people who have enough literacy can be employed as administrator of public water tap under the condition of participation in the water committee.

Add. 9 add source with Gahama source with Gahama andMuguruka sources
Gahama source with capacity of 0.8 l/s can cover only 21% of the total beneficiaries of16,107, thus development of existing Nyagasogi supply facilities using Muguruka sourcewas requested as well.

name of Gasenyi sourcechanged to Kabingo,with Kabingo I andGasebura sources
Change to actually used name at site,Gasebura source with flow rate of 1.2 l/s can cover only less than 31% of the total 16,864beneficiaries, thus rehabilitation of Kabugwe supply facilities with Gasebura source, whichare now out of order, is also requested.
Gashongora Mod.15 change of source namechange of coverage area
with Rwimond source,Gashongora sector andGahara sector to be covered

Frw13.9 of estimated O&M cost/day/capita is fairly highcompared to Frw10 of the residents' willingness to pay. Pumpfuel is costly due to large elevation gap between the source andthe distribution pond. In addition, less beneficiaries makes thisscheme unfeasible.

Frw10.4 of O&M cost/day/capita falls just outside of the upperlimit (Frw10) of the selection criteria. Considering the highgroundwater potential and the flat topography of this area, thisscheme is to be selected subject to reduction of the O&M costby means of replacing motor pump with hand pump.

Evaluation Result
Reason for Change or Deletion
Frw13.7 of estimated O&M cost/day/capita is fairly highcompared to Frw10 of the residents' willingness to pay. It ishowever planned that water supply to this area will be doneusing the excess water of Gicaca source which is located in thesame Sector after reform of administrative jurisdiction.
The water source tank and pump are being rehabilitatedapplying CDF fund. The project effectiveness is not high fromthe aspects of the less water quantity available and the limitedcoverage area.
Sovu and Rutonde Sectors are integrated into one Sectorthrough reform of administrative jurisdiction. As a result, watersupply to these 2 areas from Rwakibogo source alone ispossible and the construction cost and the O&M cost for supplyfacilities can be reduced.
Since the spring water potential of Rwakibogo, which will belongto the same Sector after reform of administrative jurisdiction, ishigh, reduction of O&M cost can be expected through watersupply from Rwakibogo source.
