French Valley and Winchester Sub-Regional Master Plan
Eastern Municipal Water District, California

West Yost developed a regional sewer master plan for Eastern Municipal Water District in the French Valley and Winchester Region. Future flows were developed from District growth projections and county land use sources. West Yost developed future infrastructure requirements as well as a Capacity Remaining analysis to estimate the growth allowed before improvements are triggered. A sensitivity analysis was performed to determine how the infrastructure requirements were impacted by the conversion of low density residential land uses from septic service to collection system service.

Key components of the project included:

  • Flow monitoring
  • Model calibration
  • Growth flow projections
  • Sensitivity analysis
  • Capacity remaining analysis
