Name of the project : The guideline study on large-scale water supply projects

Place : All districts of Eastern Province

Name of client : JICA, RWANDA OFFICE

Description of the Project: The Consultancy aims to:

• Develop a clear definition of the concept large scale/high impact drinking water project including its relevant criteria through the review of GoR policy, the long term plans as well as the consultation of main players in the WATSAN sector;
• To evaluate potential large scale resource of drinking water for Eastern Province;
• Conduct a pre-feasibility study for a maximum of five (5) potential sites selected in the Eastern Province based on the agreed criteria (under objective 1). The format of study shall serve as a model for future similar studies.

Description of services provided by the company personnel :

Component 1: Defining and documenting the concept of “large scale” water supply projects

• Develop a statement of the problem : Reasons for EWSA / the Sector to focus on large scale water supply projects
• Conduct a comparative analysis of small water systems and large scale systems and highlight the vantage ground
• Propose single definition of concept of large-scale water supply project for EWSA/ in the context of the WATSAN sector
• Highlight and explain the provisions of Policy, EDPRS II, Sector Strategy or any guiding document about  the concept
• Propose a set of criteria to determine such a project in the context of rural water supply
• Propose an appropriate framework/structure for developing and implementing such a project (partnerships model, co-funding, progressive implementation…)
• Provide basic considerations on Operation and Maintenance model
• Selecting sample sites that meet the criteria as defined in point 5 through a documentation-based review, consultations with EWSA and districts. At this stage, a site visit can be envisaged in case there is a lack of important information in order to decide on one or another candidate site. At least the following process shall be followed for selecting the sample sites :

1. a) Collecting information on main surface water resources (river, dam, lake, pond, etc),
2. b) Roughly estimating the potable water development potential of those water resources,
3. c) Listing up the suitable places for large-scale water supply facility development,
4. d) As a result, selecting the target sites for the Pre-Feasibility Studies

Component 2: Conduct a pre-feasibility Study for maximum Five (5) selected sites

• Conduct a survey for each site on the following (non-exhaustive) aspects:

1. Conduct a site reconnaissance including (hydrological and geological investigation),
2. Evaluation of water source capacity and water demand (time horizon 20 to 30 years) including the current use of water e.g. irrigation, hydropower, in order to assess the current water scarcity and future availability (water balance);
3. Conduct water quality analysis for each candidate water resource,
4. Assessment on status of existing water system(s) (if any),
5. Assess the environmental and social considerations,
6. Conduct an analysis of risks and advantages,
7. Estimation of potential beneficiaries,
8. Analyze the possible technical options for the project (design requirements; water abstraction; pumping stations; water treatment plants ; transmission mains ; water distribution network),
9. Discuss basic considerations on investment and financial viability(Financial and economic analysis –cost benefit analysis),
10. Propose a rough structural drawing, profile and topographic map of the systems,
11. Detailed investment cost breakdown;

• Mapping work (location of the sites, access from the main road) for the selected sites on a general topographic map of the Eastern Province
• Formulate relevant recommendations with regard to future similar studies and/or the implementation of sampled projects, and a conclusion to the Study.
• Define the priorities among the sample sites and propose an implementation plan
