Sewer Model Development and Analysis, Clark Regional Wastewater District

About

BHC developed a comprehensive model of the District’s sanitary collection system, using MIKE Urban software. The model was created by importing collection system data from the District’s GIS database, including over 10,000 pipes and 67 pump stations. Existing, 20-year, and buildout flow scenarios were analyzed to identify improvements necessary to re-direct Ridgefield flows to the District’s system, mitigate surcharging, accommodate growth, and efficiently convey flows to the Salmon Creek WWTP.

Features:

  • MIKE Urban model with Rainfall Dependent Infiltration (RDI) Module
  • Flow loading and dry-and wet-weather calibration to District meter data
  • Flow projections and I/I degradation for future scenario analysis
