Backflow Water Distribution Study

BKI was selected by the City of Shreveport to provide analysis of the existing potable water distribution system, review previous engineering studies for the City and formulate recommendations for near-term, short-term and long-term protective measures to the City distribution system. BKI created both hydraulic and electronic models of the existing potable water distribution system in the City, which were used to predict flow, pressure, reidual, age containment transport and other parameters of the improvements. The models also made future connections between it and the City's GIS, and SCADA system feasible.

The hydraulic analysis began with creating a representative computer model of the existing potable water distribution system in the City. It was calibrated with data obtained from a field testing and investigation program. This model was a hydraulic and water quality model, useful for prediction in flow, pressure, residual, age, containment transport and other parameters. With the calibrated model a detailed review was completed, stressing homeland security, fire preparedness, residual disinfectant levels, and sufficient pressures. The entire model was constructed and all computations were performed within and ArcGIS framework. This allowed the City of Shreveport GIS data to be used as raw input and the model output to be reviewed within the City's GIS database making future connections between the model, the City's GIS and the City's SCADA system feasible.
