Samoa : Alaoa Multipurpose Dam Project

Sovereign Project | 52111-001

The multipurpose dam is intended to increase flood protection, supply seasonal water, and provide additional hydropower. The primary objective of this proposed project is to enhance resilience to increasingly intense cyclones by mitigating Apia City flooding associated with extreme rainfall events on the upstream catchment of the eastern and eastern-central branches of the Vaisigano River. The secondary objective is to improve the stability of the water supply during dry periods and reduce the turbidity of raw water taken into Apia's main water treatment plant during flood periods. The tertiary objective is to install a hydropower capacity of 0.60 MW, generating 2.12 GWh of clean electricity. The project will support the government's 70% renewable energy target for electricity generation by 2031. The project will enhance non-physical flood management systems and capacity and the biodiversity conservation and management capacity associated with the proposed dam development.

Description
The multipurpose dam is intended to increase flood protection, supply seasonal water, and provide additional hydropower. The primary objective of this proposed project is to enhance resilience to increasingly intense cyclones by mitigating Apia City flooding associated with extreme rainfall events on the upstream catchment of the eastern and eastern-central branches of the Vaisigano River. The secondary objective is to improve the stability of the water supply during dry periods and reduce the turbidity of raw water taken into Apia's main water treatment plant during flood periods. The tertiary objective is to install a hydropower capacity of 0.60 MW, generating 2.12 GWh of clean electricity. The project will support the government's 70% renewable energy target for electricity generation by 2031. The project will enhance non-physical flood management systems and capacity and the biodiversity conservation and management capacity associated with the proposed dam development.
Project Rationale and Linkage to Country/Regional Strategy
The project will support Samoa's climate adaptation and mitigation efforts by addressing interrelated development challenges in flood management, sustainable water supply, and energy security. The proposed Asian Development Bank (ADB) financing will support the construction of a multipurpose dam with a run-of-river small hydropower plant (SHP) in the capital Apia and provide flood management systems (nonstructural) and capacity building and biodiversity conservation and management supports.

Stakeholder Communication, Participation, and Consultation

During Project Design
The ADB safeguards policy puts a strong emphasis on ensuring inclusive and meaningful consultations with all affected persons and other key stakeholders. Hence, as part of the ongoing project preparation for the Alaoa Multi-purpose Dam Project, the government with support from a Communication Specialist engaged by ADB, is implementing a Stakeholder Consultation and Communication Plan which requires consultations and engagement with affected persons such as those who could experience physical eviction and/or economic loss or livelihood impacts due to the project. The key areas for consultation include: project information and its likely involuntary resettlement impacts to gather affected persons' feedback/concerns and how this should be taken into account in the safeguards planning; (ii) solicit recommendations on how to effectively develop grievance redress mechanism appropriate to the Samoan culture and values; and (iii) disclosure of the draft safeguards plans to solicit feedback from the affected persons before finalizing the version for posting on ADB/government websites. To date, several public consultations among the affected persons, relevant communities and key stakeholders have already been undertaken and will continually be undertaken.
During Project Implementation
Project consultation will be an ongoing process not only while we are completing the project preparation but especially during project implementation. ADB also requires consultations to be done in an atmosphere free of intimidation or coercion so affected persons are able to share their concerns and feedback without fear of retaliation. All the issues being raised from consultations are being assessed through the ongoing safeguards due diligence.

Project Data Sheets (PDS) contain summary information on the project or program. Because the PDS is a work in progress, some information may not be included in its initial version but will be added as it becomes available. Information about proposed projects is tentative and indicative.

The Access to Information Policy (AIP) recognizes that transparency and accountability are essential to development effectiveness. It establishes the disclosure requirements for documents and information ADB produces or requires to be produced.

The Accountability Mechanism provides a forum where people adversely affected by ADB-assisted projects can voice and seek solutions to their problems and report alleged noncompliance of ADB's operational policies and procedures.

In preparing any country program or strategy, financing any project, or by making any designation of, or reference to, a particular territory or geographic area in this document, the Asian Development Bank does not intend to make any judgments as to the legal or other status of any territory or area.
