Full Description

Water quality modeling is becoming popular with water utilities seeking to betterunderstand the dynamic behavior of their distribution systems. The development of awater quality model often involves intensive data collection efforts, making it difficult formany utilities to undertake. This paper illustrates an application of water qualitymodeling for small systems. Because of their compact size, water quality modeling canbe successfully implemented by small systems with minimal effort, particularly if themodeling goal is a general understanding of water quality dynamics rather than a preciseprediction of specific water quality parameters. A water quality model was developed forthe Town of Carthage, North Carolina and was used to simulate free chlorine concentrations insummer months, combined chlorine concentrations in winter months, and the movementof constituents throughout the system during a switch in disinfectants. The results of themodeling effort show that tank sizing, pipe material, and residence time all affect thewater quality in the distribution system. Includes 3 references, figures.
