Systemwide Analysis for Water System Plan Update, North City Water District

Shoreline Washington


Update to the systemwide hydraulic model in support of the District’s Water System Plan Update.  Existing system demands, demand projections and diurnal demand patterns were updated. A range of modeling related tasks were performed, including static and extended period simulation (EPS) analyses, pressure zone reconfiguration analyses, system-wide fire flow analyses, water age analyses, identification of improvement alternatives, and development of an updated CIP.


  • Hydraulic model update and calibration
  • Live modeling workshop with District
  • Updated CIP resulting in significant District savings
