AWWA DSS58688

The home of the Browns, Indians and Cavaliers is also home to one of the more complex computerized water distribution system hydraulic models. This model is integrated with a geographic information system (GIS) database of the Cleveland, Ohio Division of Water's (CWD) installed distribution system assets. Using this integration, up-to-date hydraulic models are extracted from the GIS hydraulic data in a relatively short period of time. Many of the unwritten operational rules for the system were incorporated into the model in the process of completing and calibrating the model. In doing so, a number of opportunities to make these operations more efficient were identified. The model also incorporates water quality analysis and has led to a greater understanding of how disinfectant residuals are affected by CWD's operational strategies. Includes 2 references, figures.
