  • Navigate your network to discover topological and connectivity issues
  • Find and fix orphaned nodes and dead-end pipes resulting from inconsistent source data
Gravity and Pressure Hydraulics

Engineers can analyze pressure or free surface flow conditions using a robust, gradually varied, standard-step algorithm for solving for subcritical, critical, supercritical conditions, and complex composite profiles. Unlike many gravity flow models, SewerCAD can also model pumps, force mains, and pressure sewers:

  • Analyze pressure or free surface flow conditions
  • Solve subcritical, critical, supercritical conditions, and complex composite profiles
  • Steady-state analysis for extreme flow conditions
  • Use SewerCAD’s automated design features to find cost-effective sewer designs
  • Extended period simulations (EPS)
  • Analyze and visualize how the system behaves over time
  • Animate results through time to locate hydraulic jumps and surcharging sections
  • Use common friction methods like Manning, Kutter, Darcy-Weisbach, and Hazen-Williams
  • Calculate structure headloss with a variety of methods including FHWA, HEC-22, and AASHTO
  • Analyze flow profiles with capacity and backwater analysis methods
  • Simulate real-time controls, turn pumps on and off with customizable controls
  • Diversion simulation
Loading, Infiltration, and Inflow

Flexible sanitary loading features help you to accurately estimate dry and wet weather contributions to the collection system:

  • Dry-weather load assignment using hydrographs, unit loads, and pattern-based loads
  • Customizable service area, count, total dry weather discharge, and contributing population based unit sanitary loading library
  • Pipe length, diameter, surface area, length-diameter, or user-defined infiltration load type
  • Manage and use multiple flow hydrographs for Extended Period Simulations
  • Select from pre-defined extreme flow factor methods including Babbit, Harmon, Ten State, and Federov’s, or implement your own
