TERMS OF REFERENCE FOR THE DEVELOPMENT OF RULINDO, GICUMBI, AND KARONGI DISTRICTS WASH INFRASTRUCTURE DISASTER RISK REDUCTION AND CONTINGENCY PLANS

1. INTRODUCTION

Water For People is an international non-governmental organization (NGO) that works with people and partners to develop innovative and long-lasting solutions to developing countries’ water, sanitation, and hygiene problems. The organization strives to continually improve, experiment with promising new ideas, and leverage resources to multiply its impact.

Water For People, Rulindo District, and the Ministry of Infrastructure, (MININFRA), entered into a partnership to implement Rulindo Challenge Program in 2010, GICUMBI and KARONGI WASH Programs, respectively in 2016 and 2020, to bring safe and sustainable water, sanitation, and hygiene services to the entire population of the mentioned districts.

After more than 10 years of hard work in Rulindo District, 8 years of investment in infrastructure development and sustainability activities related to WASH in Gicumbi District, and almost five years of investment in Karongi District, everyone (every school, every community, every health care facility), has access to safe drinking water, adequate sanitation, and improved hygiene practices. However, due to the topography of the districts mentioned above, water and sanitation infrastructures have been from time to time, threatened by landslides due to heavy rains leading to interrupted water and sanitation services and frequent rehabilitation of water infrastructures, especially during rainy seasons.

To address these seasonal WASH crises, Water For People, in partnership with Rulindo, Gicumbi, and Karongi Districts, plans to hire services of a qualified consultancy firm to develop a District WASH Disaster Risk Reduction (DRR) and Contingency Management Plan (DWCMP), which will help Rulindo, Gicumbi and Karongi Districts to mitigate the above-mentioned hazard/disaster and ensure sustainable WASH services in the district.

2. OBJECTIVE OF THE CONSULTANCY

General Objective

The objective of this consultancy is to develop a WASH Contingency Plan aimed at establishing a series of preparatory measures aiming at preventing or reducing impacts on WASH services in case disasters occur to the infrastructures in the three districts and establishing comprehensive disaster risk reduction strategies adopted to WASH infrastructure in the Rulindo, Gicumbi, and Karongi districts of Rwanda for the purpose of enhancing community resilience against potential disasters impacting WASH services.

Specific objectives

• Identify and map climate change-related risks affecting WASH infrastructures.
• Identify and map all infrastructures that are prone to disasters.
• Conduct a thorough risk assessment to identify vulnerabilities in existing WASH infrastructure.
• Develop operational procedures for effective response during various disaster scenarios.
• prepare the strategy to Enhance community engagement and capacity building for local stakeholders in disaster preparedness.
• Analyze potential hazards affecting WASH infrastructure
• Assess the current state of WASH facilities and identify critical vulnerabilities.
• Gather data on historical disaster impacts on WASH services.
• Establish communication protocols for timely information dissemination.
• Create a resource inventory for emergency response
• Develop guidelines for infrastructure resilience improvements (e.g., flood-proofing wells).
• Recommend training programs for local communities on emergency preparedness.
• Assess the social economic impact of the identified risks.
• Identify and suggest actions required to mitigate the identified risks.
• Define the roles and responsibilities of different stakeholders responsible for each provision in the contingency plan given the findings and recommendations per scenario.
• Propose engineering solutions, such as retaining walls or soil stabilization techniques, to improve infrastructure resilience in high-risk areas.
• Conduct flood risk assessments using hydrological and hydraulic modeling to map flood zones around critical WASH infrastructure
• Propose design modifications for new and existing WASH infrastructure to enhance climate resilience
• Develop structural and non-structural measures for flood protection, such as the construction of levees, flood walls, or the integration of green infrastructure solutions.
• Develop guidance on resilient design principles tailored to local climatic conditions, focusing on minimizing water loss, increasing energy efficiency, and reducing maintenance requirements.
• Assess geotechnical risks in areas prone to landslides or subsidence, particularly for critical WASH facilities located on sloped or unstable terrain.
• Conduct structural assessments of existing WASH infrastructure to identify areas susceptible to physical failure under various disaster scenarios.
• Propose the implementation and monitoring plan of the proposed mitigation measures to avoid or reduce the identified risks per scenario within a specific timeframe.

The consultancy will propose an appropriate methodology to deliver on the proposed assignment. This will include, but not be limited to the following:

• Review of existing documentation on disaster management including but not limited to National Disaster Management plans and laws,
• Collecting data from stakeholders and fields.
• Review of existing documentation of water supply systems of each district (maps and shapefiles).

3. SCOPE OF WORK

The consultant will undertake a review of relevant literature, including but not limited to the following:

• National DRRM policy
• National Preparedness Plan for WASH sector in Rwanda
• National Water and Sanitation Policy
• Integrated Water and Sanitation Master Plans
• Climate Risk Assessment and Climate Rationale for Rwanda
• Guidelines for Climate Resilient WASH programming in Rwanda
• District WASH investment plans
• Other relevant literature

The consultant will carry out an extensive situational analysis of all infrastructure of Karongi, Rulindo, and Gicumbi Districts and identify those that are prone to landslides, flooding, heavy rains, and other climate-related factors that could impact the water services. The Consultant will be required to develop a detailed district plan of critical mitigation measures that would be considered by the districts and the national governments while planning for future climate change adaptation and resilience.

The consultant is required to conduct the same assessment on critical sanitation infrastructures (fecal sludge treatment plants and dump sites) and suggest appropriate solutions to mitigate challenges that are affecting sanitation facilities and related to climate change.

The contingency plan will be the strategy to manage and deal with any identified risk, mainly landslides and floods.

4. METHODOLOGY

The successful consultant will propose methodologies to be used to deliver the assignment and these will be validated during the inception phase.

DELIVERABLES

Technical deliverables

• Geological and landslide susceptibility analysis report for each district: The consultant will compile and analyze relevant datasets including but not limited to topography, geology, hydrology, land use, soil characteristics, rainfall data, and historical landslide occurrences. Using an appropriate methodology, the consultant will analyze the landslide susceptibility and validate it based on the comparison with historical landslide data and adjusting parameters as necessary. In this case, slope stability analysis will be conducted to fully validate the susceptibility of landslides in a particular area.
• Detailed disaster risk assessment on WASH infrastructure for each district based on geological and hydrological status
• Hydrological and hydraulic model of each district using open-source software (such as HEC-HMS and HEC-RAS): The estimated areal rainfall will be used for frequency analysis where extreme rainfall events with 5, 10, 25, 50, and 100 years return periods will be estimated for each delineated sub-catchment in each district. Once the hydrological and hydraulic models have been developed, the Consultant will model various flooding scenarios considering climate change and land use change. At least the following scenarios will be modeled: current and future scenarios taking into account climate change and land use changes, these two scenarios will be validated by past event data that had occurred in the area referring to meteorological historical data. During the delineation of sub-catchments within the districts, it may happen that the district’s boundaries may not coincide with sub-catchment boundaries. Therefore, the consultant will consider the boundary of the contributing sub-catchment regardless of the district boundary.
• Provision of a detailed risk map for each scenario per each district
• Identification of water supply and sanitation infrastructures that are prone to risks in each scenario.
• Develop Comprehensive DRR strategies that enhance the resilience of WASH infrastructure in Rulindo, Gicumbi, and Karongi districts.
• Develop well-defined contingency plans that facilitate quick response during emergencies affecting water supply and sanitation services.
• Propose design modifications for new and existing WASH infrastructures to enhance climate resilience
• Propose engineering solutions (with detailed specifications), such as relocation, retaining walls, and soil stabilization techniques to name a few, to improve infrastructure resilience in high-risk areas.
• Provision of costed mitigation plans for risks associated with each climate change scenario.
• Produce a training manual on the WASH Contingency plan and provide training on identified district and sector staff.
• Provision of actionable climate resilient plan for existing infrastructures

Delivering timeline and expected reports.

• Inception Report: After 14 days the consultant will provide the preliminary report with a literature review, methodology, content outline of the WASH contingency plan, and proposed changes on the TORs if any.
• Interim report: After data collection and analysis for all water supply systems in each district, this is an intermediate report with the extent of risks assessed and will be submitted on the 60th day upon contract signature. The interim report will be validated in each district.
• Draft Report: The draft WASH contingency plan taking into consideration the approved scenario and proposed costed actions to mitigate the impact of identified risks per water supply system will be submitted on 80^th days after the contract signature. The draft report will be validated at each district.
• Validation workshop: The validation workshops will be organized at each district 5 days after the submission of the draft report.
• Final report: The final report will consider all comments and inputs from the validation workshops and will be submitted 5 days after the validation took place.

Note: Activities must be done concurrently in all districts
