Abstract

Geologically the Pacific island countries include high volcanic islands, low-lying coral atolls and raised atolls. The amount of rain that falls on these islands varies considerably, depending on whether the island lies in the path of the tradewinds or in the equatorial doldrum belt. The high volcanic islands receive more rain than the low lying coral atolls, due to the orographic (lifting) effect of the wind in the mountains. Rainwater catchment is essential, especially on small, low-lying coral atolls where all available freshwater needs to be conserved, managed and protected. This paper draws on the experience of water supply experts and volunteers who have dealt with various water supply facilities including rainwater catchment systems. It discusses different types of rainwater tanks, community participation and the responsibility of women. It also looks at the problems and costs of logistics in project implementation, especially on small isolated islands. The paper rests on the experiences gained in one project in Tuvalu.
