Description: Technical Report
Abstract: This report assesses the reliability of the existing Federally Owned Water Main (FOWM) system with a special emphasis on possible long-term outages. A mathematical model of the system was created using information supplied by Washington Aqueduct Division and Arlington County officials. The model was calibrated using fire hydrant flow test results. The response of the system to different pipe outages under different loading conditions was then examined using the computer model. Several alternatives for improving the reliability of the FOWM system were investigated. These alternatives include new river crossings between FOWM and Washington, DC, new pipeline construction within the FOWM system, a new storage tank, new interconnections between FOWM and an adjacent distribution system, and the use of existing interconnections between FOWM and Arlington County. Hydraulic, engineering, and economic analysis of each alternative were performed. The impact of the new and existing interconnections on the extended performance of both systems was also investigated. Recommendations to improve FOWM system reliability based on the hydraulic, engineering, and economic analyses are given. NOTE: This file is large.
