• Description:
• Request for proposals are invited for Feasibility Study for Water Supply at Motufoua School - Vaitupu, Tuvalu Tuvalu is a small sovereign country of less than 12,000 people. Consisting of 9 islands (6 atolls and 3 reef islands), Tuvalu has a total area of approximately 26 square kilometres and a coastline of 24 kilometres. The highest point is 4.6m above sea level, making it extremely vulnerable to the impacts of climate change. While water security has always been a concern for the people of Tuvalu, the impacts of climate change have threatened to diminish the very limited water sources it currently has. With no rivers or lakes, people depend on water drawn from natural aquifers and collected from rainfall. These are endangered by seawater intrusion and frequent, prolonged periods of drought caused by climate change. Motufoua Secondary School (Motufoua) is located at the southern end of Vaitupu atoll. It is the largest and the only public boarding high school in Tuvalu apart from a single private high school located in the capital island. From 2018-2022, the average number of students and staff was around 650 people. The school is fully funded by the government and has the most and majority of essential facilities designed for boarding school. Motufoua has 6 water cisterns, but they are not used due to extensive damage. An assessment made by the Public Work Department in the wake of the dry spell this year reported a large-scale deterioration on roofing, piping system and water cisterns for which a significant cost for rehabilitation would be needed. Cracks, rusty on structural elements and extensive damages were identified in and around the unused water cisterns. The condition of the cisterns is given below. Cistern Storage Capacity Status Year built Donor No.1 225 mᶟ Good 1997 Japan No.2 225 mᶟ Good 1997 Japan No.3 250 mᶟ Damaged 1987 N/A No.4 250 mᶟ Damaged 1987 N/A No.5 90 mᶟ Damaged 1979 N/A No.6 90 mᶟ Damaged 1979 N/A In 2005, 18 water tanks were installed as temporary replacement for water storage for drinking and cooking. Each water tank holds 10,000 litres. During droughts, the school is very vulnerable and water security is a challenge. Groundwater from wells is used for washing, toilet flushing and other activities requiring water. The quality of groundwater varies across Tuvalu and can be highly saline as well as contaminated from pit latrines and septic tanks. The Ministry of Finance in Tuvalu is currently developing a proposal to be submitted to the Adaptation Fund requesting support to provide reliable access to a safe and resilient water supply to Motufoua under a changing climate. The objective of this piece of work is to provide the technical, gender equality and social inclusion (GESI), and environmental and social safeguards assessments that will feed into the proposal. • The Climate and Abstraction Impacts in Atoll environments (CAIA) project • Summary of the groundwater field investigations conducted on Vaitupu, Proposed Activities and Methodology The consultant shall perform the following four tasks: Task 1: Inception Task 2: Assess water needs Task 3: Assess water supply options Task 4: Assess gender equality and social inclusion Task 5: Assess environmental and social safeguards One mission trip is expected to be carried out during this project. We advise bidding consultants to consider ferry schedules. Ferries often only stop at an island for a few hours, and the schedules are often changed at the last minute. Before bidding, the consultant should consider whether chartering a boat will be needed to stick to the timeframes and have the required amount of time on island. Task 1: Inception The project will start with a call between the consultant, the Ministry of Finance, and GGGI to confirm he scope and objectives. The consultant shall then gather and review relevant data and information about the school, the islands geography, climate and water sources. A mission plan should be developed with key data that will be collected. Deliverable 1: Inception report with confirmation of objectives and workplan and summary of desktop review and gaps (maximum 5 pages plus appendices) Task 2: Assess water needs To gain a deep understanding of current water needs at Motufoua, the consultant shall conduct desktop research and visit the school and the surrounding area to collect essential data. This will involve the following: • Stakeholder engagement: Identify and engage relevant stakeholders, including school administrators, local community leaders, teachers, parents, and students • Water sources assessment: Identify existing water sources (e.g., wells, springs, rainwater harvesting systems). Evaluate their quantity and quality. Test water samples for contaminants if necessary. • Infrastructure inspection: Examine the condition of water storage tanks, pipes, roof catchment, gutters, and cisterns. Note any leaks, damage, or maintenance needs. • Water demand assessment: Estimate the daily water demand of the school, including drinking, sanitation, and other needs. • Climate and rainfall data: Collect climate and rainfall data to understand seasonal variations and assess the feasibility of rainwater harvesting. • Planned projects: Understanding planned projects in the medium term will help identify where there are still gaps to be addressed. In particular, SPC plan to develop a horizontal gallery in Vaitupu which will increase water supply. The consultant shall then analyse the data collected to determine whether the existing water sources and infrastructure meet the school's water needs and identify any gaps or issues that need to be addressed. As most of the water used is from rainwater, particular attention should be given to wet season verse dry season needs, and how often and severely droughts are expected to impact water supply. Data series analysis will be needed to understand droughts and water demand. A key document to be utilised during this task is “Climate and Abstraction Impacts in Atoll Environments: Groundwater Field Investigations Vaitupu, Tuvalu”. The consultant shall first deliver a draft report based on desktop research and virtual meetings. The draft report shall highlight the additional data needed for the assessment and the plan to collect that data in country. Once the consultant has completed the mission, a final report shall be submitted. Deliverable 2: Water needs assessment (maximum 20 pages plus appendices) Task 3: Assess Water Supply Options The consultant shall compare water supply options and make recommendations, this will include an assessment of the following factors: • Quantity and reliability: Determine the volume of water available from each source and its reliability throughout the year, considering seasonal variations and drought periods. • Water quality: Analyse the water quality of each source, including tests for contaminants and suitability for drinking and other uses. • Sustainability: Evaluate the long-term sustainability of each source, considering factors like climate change, drought, and the potential for depletion. • Infrastructure requirements: Assess the infrastructure needed to access each water source. If necessary, explore water storage, treatment and purification technologies that can be applied to the selected water source to ensure safe and clean water supply. This will include taking borehole samples of groundwater for larger structures. • Cost: Estimate the capital and operational costs associated with each option. • Environmental and social impact: Consider the environmental and social impact of each option (in parallel with Task 4 and 5). The consultant shall then use a systematic method (e.g., a scoring system or a multi-criteria decision analysis) to rank and compare the water source options based on the defined criteria. Based on the analysis, solutions shall be recommended that best provide reliable access to a safe and resilient water supply. The rationale for each recommendation should be set out in the report. Deliverable 3: Report that summarizes the options analysis, recommendations, and preliminary cost estimates (maximum 30 pages plus appendices). Task 4: Assess Gender Equality and Social inclusion The GESI assessment will involve engagement with the school community and local stakeholders to gather their input and preferences regarding the water supply options. Stakeholders needs and concerns shall feed into the supply options analysis and evaluation in Task 3. The GESI assessment will include the following steps: • Stakeholder identification: Identify and engage with all relevant stakeholders, including school administrators, teachers, students, parents, local community members, and marginalized groups. Ensure diversity in participation. • Desk review: Conduct a review of existing literature, reports, and studies related to gender and social inclusion issues in the project area. This helps to understand the historical context and existing challenges. • Stakeholder consultation: Engage in open and participatory discussions with community members, especially women and marginalized groups, to gather their perspectives and insights on water supply needs and challenges. Create a safe and inclusive space for dialogue. • Gender analysis: Identify gender-specific roles, responsibilities, and access to water resources at the school and in the wider community. Consider questions like who collects water, who makes decisions about water use, and how water affects females and males differently. • Social inclusion assessment: Identify marginalized or excluded groups, such as people with disabilities. Understand their unique challenges and needs related to water access. • Gender and social inclusion impact assessment: Assess the potential impacts of the proposed water supply project on gender and social inclusion. Analyze how the project may affect the roles, responsibili
