Description
North Carolina experienced record drought in 2007, especially the Triangle area in the central part of thestate. The drought caused extremely low water levels in the reservoirs that supply drinking water to thecities of Raleigh and Durham, prompting them to look to their neighbors for emergency supplies. TheTown of Cary, a neighboring water system which is supplied by Jordan Lake, had sufficient supplycapacity to meet its needs and to supplement Raleigh and Durham, primarily in the winter when demandswere lower.This paper describes the hydraulic modeling that determined the maximum amount of water that Carycould supply to Raleigh and Durham on a sustained basis. The project identified limitations imposed byplant capacity, pump sizes and the capacity of the pipe systems on either side of existing and potentialinterconnections.The study involved combining three large hydraulic models and simulating flow between systems forextended periods. The combined model predicted flow rates, pressures and tank performance. The modelinvestigated various scenarios aimed at maximizing flow through interconnections given pressure zoneconfigurations and other unique features of each distribution system. Includes table.
