B. Stormwater inflow E. Low pressure in the sewer system
C. I/I F. None of the Above

4. Sewer systems are designed to maintain proper flow velocities with?

Sewer System Capacity Evaluation - Testing and Inspection

8. The collection system owner or operator should have a program in place to periodically
evaluate this missing term in both wet and dry weather flows and ensure the capacity is
maintained as it was designed.
A. Design flow(s) D. Capacity of the sewer system
B. Stormwater inflow E. Low pressure in the sewer system
C. I/I F. None of the Above

9. The capacity evaluation program evaluation begins with an inventory and characterization
of the?
