With technical support from the Asian Development Bank (ADB) and the Ireland Trust Fund for Building Climate Change and Disaster Resilience in Small Island Developing States (ITF), a comprehensive study is being conducted to assess strategies for ensuring sustainable, safe, and affordable drinking water access for all populations in Samoa, while considering the impacts of current climate change scenarios. This initiative builds upon prior ADB and donor assistance in Samoa's water and sanitation sector, aiming to enhance service coverage and performance through strategic planning and appropriate technologies. The project will yield a 10-year national water supply masterplan, outlining policies, standards, and guidelines for sustainable water supply systems across Samoa, along with a costed and prioritized investment plan to facilitate informed decision-making for achieving sustainable access to safe drinking water.
Phase 1 – Inception Report
-
In consultation with key stakeholders the consultants will prepare an inception report. The report should include (i) a detailed workplan, (ii) desk review of existing information, (iii) a baseline assessment, (iv) a situation analysis, and (v) a needs assessment.
-
The study should maximize the use of readily available information. Some primary data collection is expected to reinforce existing information and to enhance the studies. Issues for study should also be guided by relevant ADB or European Economic Community (EEC) publications including: “Guidelines for Water Resources Development Co-operation (1998);” “Project Cycle Management Manual (2001);” “Manual for Financial and Economic Analysis (1997);” and “Manual on Environmental Procedures and Methodology (1993).” Lessons learned from past project and program evaluations in Samoa, and elsewhere, should also be considered.
-
Consolidation of information and a situation analysis will provide a common understanding of the current water supply status, its short-comings, and serve to support the development of options. Items for review and assessment:
-
the extent of waterborne diseases and the impacts of inadequate water supply in Samoa;
-
the adequacy of policies, legislation, institutional arrangements, and programs for service delivery;
-
an assessment of current roles and responsibilities and review the institutional capacity of these organizations (including SWA, community-based service providers, and the private sector) to undertake these roles;
-
the operational performance of SWA including service levels, coverage, and regional variations;
-
the financial performance of the SWA including costs to deliver services (disaggregated according to supply/demand zones), operation, maintenance and management costs, tariff revenues, and capital replacement profiles;
-
water resource assessments and water quality assessments and determine water resource issues and constraints;
-
Review of existing SWA coverage area (i.e., population served and combined length of functioning pipeline) and methodology used to determine coverage area.
-
Assessment of the operational performance of existing SWA assets and preparation of conditional assessment plan to upgrade all assets in need of repair/upgrade.
-
the use and appropriateness of technology in the different service delivery systems; and
-
an overview of SWA performance.
-
-
The inception report will reaffirm the relevance of a water supply and sanitation (WSS) program and ensure a program is designed to meet the real needs and problems of target beneficiaries. The consultants will confirm the following:
-
the coherence of a WSS program within the overall framework of national development, development policies, etc.
-
the nature, number and type of beneficiaries and other stakeholders that the proposed program will potentially affect;
-
all organizations and agencies affected by or involved in the proposed program;
-
all major problems experienced by the supposed beneficiaries (including rural communities) of the program and by any other parties likely to be involved, the causal interrelationships of these problems, and the intersectoral links;
-
other interventions or priorities by any national organization or donor which may be affected by the proposed program;
-
information from previous studies and evaluations relevant to the proposed program.
-
-
The inception report should emphasize the need for SWA to progress towards digital transformation. This report should identify areas that would benefit from investment in modern technology as well as establishing a strategic plan outlining SWA goals for digital and technological development and creating steps to ensure that these goals are met.
-
Following endorsement of the inception report by SWA, the consultants will begin Phase 2. Endorsement by SWA comprises approval by the Board of Directors acting on the advice of the Managing Director.
Phase 2 – Preparation the draft final water supply masterplan and investment plan
-
In consultation with key stakeholders the consultants will prepare draft final water supply masterplan and investment plan. Based on findings from the Inception Phase, the draft masterplan and draft investment plan should include an evaluation of the (i) feasibility, (ii) assumptions, and (iii) sustainability of the proposed solutions.
-
The consultants will determine the feasibility of alternative solutions to deliver WSS services across different supply/demand zones. Technical options should take account of the hydrological and hydro-geological regimes in different supply/demand zones and result in preliminary designs for each zone. The consultant shall verify water resources and water quality information and carry out additional analyses (e.g., hydro chemical analysis) where necessary at potential water sources. Technical solutions should also involve investment in advanced technologies and applying them to further improve the authority’s performance and service delivery to Samoa and its customers (e.g., SCADA, smart water meter systems, intake level monitoring devices, etc.). An analysis of existing and projected water demands up to a design horizon of 20 years, including an analysis of elasticity of demand with price will be undertaken.
-
The Study will include establishing a contingency plan for the design and implementation of a new Trunk Main water supply purposed for supplying various demand zones in Savaii and Upolu. Key stakeholders shall be consulted and involved in the planning process.
-
The identification and analysis of options should not consider technical concerns alone but should also consider institutional and other means to improve efficiency and sustainability of service delivery. Solutions should be consistent with the economic and financial, institutional and management, environmental and socio-cultural frameworks. The analyses should ensure involvement of key stakeholders with recommendations formulated in discussion and consultation with these stakeholders.
-
The Study will detail any assumptions/pre-conditions that would be necessary before the WSS options could be designed and implemented. This may include further essential studies and analyses and the consultant should include definition, phasing, and costing of such activities where necessary.
-
The sustainability of proposed WSS options will be determined by an assessment of key sustainability factors. The Consultants are required to use their professional experience to review and bring to the attention of the Government and ADB all relevant factors ensuring sustainability including (but not limited to):
-
policy framework and support measures:
