DAM EXPERT FOR LARGE DAMS PANEL OF EXPERTS

1 Introduction and Background

The World Bank approved $300 million in financing under the International Development Association’s (IDA’s) grant, credit, and scale up window to help the Government of Rwanda increase the use of irrigation and commercialization among producers and agribusiness firms to support value chains, and to increase access to agricultural finance.

The Commercialization and De-Risking for Agricultural Transformation Project (CDAT) will support the Government to provide services and create an enabling environment for the private actor throughout the agricultural value chain. It will finance public investments in the seeds sector, develop and rehabilitate irrigation systems on over 17,673 ha, provide accompanying land husbandry development on about 10,986 ha in surrounding water catchment areas to increase productivity and promote climate smart agriculture.

The project will also support commercialization by helping farmers’ access markets and availing matching grants for investments in mechanization, post-harvest infrastructure and processing equipment. A CDAT challenge fund will invest in particularly innovative solutions for the sector that can be brought to scale. The project is nationwide and is foreseen to directly benefit at least 235,000 households, including women and youth.

In partnership with financial institutions, the Commercialization and De-Risking for Agricultural Transformation Project will seek to enhance access to affordable financial services and products in the agricultural sector by providing short and long-term financing and reducing risks and challenges faced by agricultural value chains through strengthening market linkages and scaling up agriculture insurance.

The project development objectives indicators are:

• Increase in share of agricultural produce sold by participating producers.

• Increase in the cultivated area being irrigated in new and rehabilitated schemes.

• Increase in value of agricultural production quantities procured by participating aggregators (cooperative and contract buyers).

• Increase in number of borrowers obtaining agricultural loans from participating financial institutions.

• Total number of benefitting households reached by the project.

According to ESF/ESS4 Annex 1: Safety of Dams, It is the Bank's Good practice note on Dam Safety, the safety of these facilities must be independently reviewed, that any needed corrective measures be implemented to ensure the safety of the dams, and that dam safety be subsequently monitored by the responsible authorities.

The following terms of reference are therefore outlined to guide the direction of activities of the Dam Expert for a Panel of Experts (PoE) for Kageyo and Warufu Projects. The PoE will concern itself primarily with the safety aspects of Kageyo and Warufu Dams. The primary objective of the PoE is to provide an independent and high level technical evaluation of the safety of the proposed dam(s). Aforementioned sites will be primarily be considered at first phase and if there is a need to incorporate more dam sites the project management will notify consultants.

The reports of the PoE are to become the basis for conducting any necessary actions to upgrade the proposed design and operation of the dam(s) from a safety perspective.

• Project Description

With the support of the World Bank, the Rwanda Agriculture and Animal Resources (RAB) through CDAT Project will develop 17,673 ha multiple irrigation schemes across the country. The Bank will finance the detailed design and irrigation development for Kageyo and design review of Warufu irrigation schemes as well as project implementation.

2.1 Kageyo Dam

Kageyo dam site is proposed downstream of the Kageyo village. The dam site is proposed at the location of an existing small dam of 3.5MCM where the dam axis of the new dam will be just downstream of the existing dam. As per the feasibility study the new dam will be constructed on top of the existing dam incorporating it into its upstream slope like an upstream coffer dam (see Figure 2.1). The anticipated reservoir capacity according to the feasibility study is approximately 18 MCM for irrigating 2,442 ha command area. The dam height from river bed level is expected to be around 11m with crest length of 598m.

The salient features of the dam and command area taken from the Feasibility Study are illustrated below.

2.2 Warufu Dam

The Warufu site is a multi-purpose project aiming at developing 3,000 ha irrigation, providing drinking water supply of 5,000m3/day to 240,000 people and generating 1,260mWh/yr electricity sufficient to light about 4,000 houses in the project area. It involves construction of a 20 m high dam (above river bed level) to store 25 Million m3, 3,000 ha irrigation system, and land-husbandry technologies in the irrigation area and catchments. Water supply outlets for hydropower and domestic water supply are also be provided. The detailed study was developed and approved by the former LWH, World Bank funded Project under MINAGRI in 2016, and the design was prepared by two Greek Consulting firms in JV; Z&A P. ANTONAROPOULOS AND ASSOSIATES (Leading company) & G. KARAVOKYRIS AND PARTNERS CONSULTING ENGINEERS (Z&A).

Warufu project is located in Gatsibo and Nyagatare Districts of the Eastern Province of Rwanda. The proposed dam site is located 0.7 km upstream of the road bridge next to Nyagahanga town. The dam is reached from either the Kayonza – Kagitumba asphalt road and then the earthen road near Kabarore Gatsibo, or the Kigali – Byumba asphalt road and then the Byumba – Nyagatare asphalt road to Nyagahanga town where the dam site is located and further to Ngarama town which is in the command area. The coordinates of the dam axis are E 524,795/N 4,821,009.

Currently the client is on the process of hiring a consultant. This consultancy service relates to the design review updates and supervision of construction works of Warufu Dam, and the command
