Integrated Water Resource Management (IWRM) offers a systematic approach to address the sustainable development, allocation and monitoring of water resources for Pacific island Countries (PICs). The key concept of IWRM is that it provides a framework to integrate societal, economic and environmental considerations in water resource management. It recognises that all water use is interdependent and therefore should be managed in an integrated manner.
The Republic of Nauru is an isolated, uplifted limestone island located 41 km south of the equator at 0o 32' S latitude and 166o 56' E longitude. The total land area of Nauru is only 22 km2 (2,200 ha).
Small island nations in the Pacific, such as Nauru, have critical water supply problems. Nauru is a permeable island with very little surface runoff and no rivers or reservoirs. Potable water is collected in rainwater tanks from the roofs of domestic and commercial buildings. Water for nonpotable uses is obtained from domestic bores at houses around the island. There are four small desalination plants on the island, of which two are operating and supply Menen Hotel and the refugee camp.
