Access to safe drinking water is a basic need and is one of the most important contributors to public health and to the economic health of communities. Pacific island countries have yet to overcome the challenge of providing a safe and adequate supply of drinking water to its populations. Infectious, waterborne diseases, such as Typhoid and Cholera and newly emerging pathogens are a major cause of morbidity and mortality within the Pacific region. The World Health Organization (WHO) report that about 2 million people in the world die each year due to diarrhoeal diseases, most of them are children less that 5 years of age. The worst affected are the populations in developing countries. Lack of access to safe drinking water is one of the main contributors to this situation. Traditional approaches that rely on sampling and testing water have failed to achieve extensive improvement in access to safe drinking water. Pacific island countries are committed to achieving targets specified in the Millennium Development Goals (2000), including halving the proportion of people without access to safe drinking water by 2015. A new strategy is now being promoted globally that is based on risk management principles – drinking water safety planning.

The importance of safe drinking water for health and development in the Pacific Island Countries (PICs) has been reflected in many regional action plans and policies. Through the Regional Action Plan on Sustainable Water Management (Sigatoka, Fiji, 2002) Pacific Island Countries outlined actions that were needed to achieve sustainable water management through collaborative efforts by water sector authorities and inter-sectoral partners. The WHO workshop on Drinking Water Quality Standards and Monitoring in Pacific Island Countries (Nadi, Fiji, 2005) developed a Framework for Action on Drinking Water Quality and Health in Pacific Island Countries, designed to support the implementation of drinking water quality actions envisioned in the Regional Action Plan. The Pacific Island Countries embraced the Water Safety Plan concept during the workshop and this was reflected in the Regional Framework. It was recommended that PICs should use Water Safety Plans to better manage their water supplies to ensure safe quality drinking water for Pacific communities.

Flooding imposes significant costs on households and businesses located in the lower Vaisigano catchment area. SOPAC, under the European Development Fund (EDF) project Reducing Vulnerability of Pacific ACP States, has worked with the Government of Samoa to develop the Samoa Flood Management and Action Plan, which identifies actions for government agencies, the private sector, NGOs and communities responsible for flood and floodplain management that can assist in reducing flood risks in Samoa, particularly in the lower Vaisigano catchment area located in Apia, which is subject to frequent flooding.

The Pacific Islands Applied Geoscience Commission (SOPAC) is currently executing the project Reducing Vulnerability in Pacific ACP States with funding from the European Development Fund (EDF). The project has the objective to reduce Pacific ACP States' vulnerability to natural disasters affecting their coasts through the development of an integrated planning and management system which targets: hazard mitigation and risk assessment; alternative sources of aggregates for construction; and water resources and sanitation. Major activities undertaken through this project with participating countries are: -assessment of aggregate resource supplies to mitigate the impact of unsustainable aggregate mining from the coastline; -development of bathymetric maps, 3D bathymetric and hydrodynamic models spatial databases relating to resource use, exploration and survey, and vulnerability to disasters; and -investigating and raising awareness about coastal processes.
