Water Supply Analysis Study for the Island of Saipan.
Abstract
The Saipan water system is characterized by leaks, poor quality water, inadequate quantity of water, and deteriorated transmission lines. Several water supply alternatives for public water use on Saipan were evaluated. These alternatives involve developing new sources and/or improving the distribution network. Part II of this report describes the water resources on Saipan, potential sources for future development, and analyses of six alternatives related to sources. These source-related alternatives represented various combinations of using existing sources, adding new sources, abandoning poor quality wells, and leak repair. Alternatives involving the distribution system improvements are described. These alternatives included the improvements suggested by a 1982 contractor report and various modifications to the existing system including service lateral repair, improvement of system operations, and installation of a dual system. Complete replacement of the distribution network was also evaluated. A computer model of the distribution network was developed and then calibrated using fire flow test results. This model was used in evaluating the distribution alternatives. The model will be useful in future management of the system. Three combinations of source and distribution alternatives offer advantages of source adequacy, water quality improvement, and operational simplicity. Order of magnitude costs for each alternative are given.
