On all islands in the Republic of the Marshall Islands (RMI) rainwater is the primary source of freshwater, putting the country at high risk from droughts. The water sector was therefore chosen by the RMI Government to benefit from the Pacific Adaptation to Climate Change (PACC) project which has been working since 2008 to increase the country’s resilience to drought events. The island of Majuro was selected as the site for the project as it is the most densely populated area in the RMI. This report details the process undertaken to design and implement various measures to enhance Majuro’s water reticulation system.
