CONSULTANCY SERVICES TO CARRY OUT FEASIBILITY STUDY AND DETAILED DESIGNS FOR WATER SUPPLY IMPROVEMENT IN BUGESERA DISTRICT

Background and Objectives of the Project

The Water and Sanitation Corporation (WASAC) is responsible for the provision of water and sanitation services across Rwanda. According to the National Strategy for Transformation (NST2), the Government of Rwanda has placed high priority on the development of safe and adequate water supply and sanitation services as a key instrument for fighting poverty and accelerating socio-economic development. The target of NST2 is to ensure universal access to water supply for productive use and scale up access to all villages countrywide. 

As part of an ambitious multi-country urban water initiative, WaterAid intends to support WASAC with interventions to improve water supply service delivery in Bugesera District, with a population of about 590,000 people.

Bugesera district is one of the seven districts of the Eastern province of Rwanda. It is located in the South west of the Province. It is divided into 15 sectors, and it is one of the fastest growing districts in Rwanda with an increasing urban population, especially in areas around Nyamata sector. According to the Rwanda Population and Housing Census of 2022, Bugesera had a population of 551,103 people (271,468 males and 279,635 females). About 75.1% of private households in Bugesera (87.8% in urban and 66.4% in rural) use an Improved Water source compared to the national average of about 82.3%[1]. It is clear that most households, especially in the rural areas, still depend on unimproved water sources, leaving the population exposed to the risk of water borne diseases.

The water supply systems in Bugesera district are characterised by inadequate production capacity to meet the growing water demand currently estimated at 31,031 m³/day.  This is compounded by old water supply infrastructure and a high rate of Non-Revenue water (NRW) currently estimated at 42.4%. There is clearly a need for urgent interventions aimed at increasing access to adequate water supply for the communities in the district.

Objectives

The consultant shall carry out a feasibility assessment and detailed designs including Environmental and Social Impact Assessment (ESIA) and associated Environmental Social Management Plan and Resettlement Action Plan for water supply interventions in Bugesera District. The Feasibility assessment shall consist of a review of available feasibility studies and investment plans for the district and shall include socio-economic and technical assessments. The Socio-economic assessment shall incorporate a review of financial sustainability, social inclusion, institutional and management set-up, as well as a review of the legal and policy environment. The technical assessment shall include an assessment of water resource adequacy, climate change impacts, and detailed design of interventions including engineering surveys and designs. The consultant shall also prepare tender documents and support procurement of contractors.
