摘要

North Carolina experienced record drought in 2007, especially the Triangle area in the central part of thernstate. The drought caused extremely low water levels in the reservoirs that supply drinking water to therncities of Raleigh and Durham, prompting them to look to their neighbors for emergency supplies. ThernTown of Cary, a neighboring water system which is supplied by Jordan Lake, had sufficient supplyrncapacity to meet its needs and to supplement Raleigh and Durham, primarily in the winter when demandsrnwere lower.rnThis paper describes the hydraulic modeling that determined the maximum amount of water that Caryrncould supply to Raleigh and Durham on a sustained basis. The project identified limitations imposed byrnplant capacity, pump sizes and the capacity of the pipe systems on either side of existing and potentialrninterconnections.rnThe study involved combining three large hydraulic models and simulating flow between systems forrnextended periods. The combined model predicted flow rates, pressures and tank performance. The modelrninvestigated various scenarios aimed at maximizing flow through interconnections given pressure zonernconfigurations and other unique features of each distribution system.rnThis presentation may help other water utilities face the challenge of supplying the state’s growingrnpopulation using limited water supplies during emergencies such as drought, contamination, main breaks,rnand equipment failures. Interconnections between water systems play an important role in maintainingrnreliability and planning for contingencies. This project demonstrates the value of hydraulic modeling inrnmeeting these challenges.
