Pressure Sewer System (PSS) Design Assistant

Enter pipe network details and pump station information. The tool calculates estimated friction losses, TDH, concurrent pump operation, and checks minimum velocity based on the principles in the provided Pressure Sewer Design Guide Formulas, using simplified methods (Hazen-Williams, approximated minor losses).

1. System Parameters
