You have entered the website of the Water and Environmental Research Institute of the Western Pacific (WERI) at the University of Guam. We are currently six faculty and five staff and our mission is to seek solutions through research, teaching and outreach programs, to issues and problems associated with the location, production, distribution and management of freshwater resources in Guam, the CNMI and the FSM.
The purpose of this project was to develop a model of the water distribution system for Moen Island in Truk Lagoon. The water distribution system on Moen Island is one that has been plagued with operating problems for years. Even though there appears to be an adequate supply of water, the system is not operated on a 24-hr a day delivery basis and there are also problems with leakage, over use and back flows into the system. System data was gathered and two system models were developed for the water distribution system. The first model was of the Southfield area on the south end of the island. This model is a comprehensive model and can be used to study individual use rates and the operation of an adequately constructed system. The second model is of the entire island water distribution system, but all the individual services have not been identified. Although this second model is not as comprehensive as the Southfield model, it is still valuable in that various operating schemes can be investigated to optimize the coordination of available supplies, storage and demands. A complete listing of raw and annotated data for each model is contained in the appendices to this report.
Development of a water distribution model is only the first phase of solving the many problems with the Moen Island distribution system. This report describes in detail a series of five follow-up studies that will use the system models. The follow-up studies should be useful in determining solutions that are both sound in engineering concepts and also feasible in both a political and social sense.
