Event Description

Participants will be introduced to advanced topics like dynamic simulations, load calculation and allocation, field data monitoring, dry weather and wet weather model calibration, and planning system improvements. To reinforce concepts learned during the course, participants will engage in hands-on EPASWMM tutorials for each section of the training.

About the Event

Learning Objectives

Participants will be introduced to the following advanced topics.

  • Dynamic Simulations: What are the advantages of dynamic simulations over static simulations? What types of input data are important when building your dynamic model?
  • Load Calculation and Allocation: What is the importance of proper load calculation? What is the best method for allocating the loads? What are the best sources of load data (water mater, population, etc.)? How should I predict future loads?
  • Field Data Monitoring: How to review recorded flow signals to identify any missing recording periods, anomalies in patterns, and potential recording errors. How to estimate and allocate inflow and infiltration rates (GWI and RDII). How to analyze dry weather flows and develop diurnal patterns.
  • Dry Weather and Wet Weather Model Calibration: What parameters should I adjust? When and by how much should I adjust them? What sources of input data do I need to properly calibrate my model? How accurate does the calibration need to be? What are the steps for calibrating my model? How to use the 3-triangular hydrograph RTK method to generate accurate rainfall driven inflow and infiltration flows (RDI&I) in the mode?
  • Planning System Improvements: What evaluation and planning criteria should I use? How should I go about planning infrastructure upgrades? How do I size pipes and pumps facilities for future scenarios? How should I evaluate operating strategies?

Finally, at the end of the training session, participants will have the opportunity to play the Aqualibrium competition to test their newly acquired skills in hydraulics. The Aqualibrium competition is a fun way to learn about the complexity of network hydraulics. The aim of the competition is to distribute 3 litres of water equally between three reservoirs (containers) placed randomly on a grid of 16 points. Participants will build a pipe network between a water source and the three reservoirs using pipes of different diameters.


A basic level of proficiency in EPASWMM is assumed and a fundamental understanding of the operation of sanitary sewer collection systems is expected.
