The Tarawa Water Master Plan (TWMP) is a response to widespread public concerns over freshwater, voiced during wide spread public consultations conducted during the National Adaptation Program of Action, Kiribati Adaptation Project Phase I (KAP I). It was developed by Professor Ian White, Australian National University, under the Kiribati Adaptation Project Phase II Water Component Project 3.2.1, supported by AusAID, and was overseen by the National Water and Sanitation Coordination Committee under the chair of the Ministry of Public Works and Utilities and by the National Adaptation Steering Committee under the chair of the Office Te Beretitenti. The invaluable assistance of Tony Falkland of Island Hydrology Services, a tireless and longstanding friend of Kiribati and the help of Marella Rebgetz, KAPII Water Specialist and the staff of the Kiribati Adaptation Project (II) Project Management Unit (PMU) is gratefully acknowledged. We thank GWP Consultants LLP for providing data for North Tarawa. This plan is based on the National Water Resources Policy and its accompanying National Water Resources Implementation Plan.
