SoilPipe

Size soil drainage pipes and calculate gradient for self-cleansing velocity

Engineering AIFree

SoilPipe sizes foul and surface water drainage pipes from fixture unit loading using simultaneous demand probability methods per BS EN 12056 and UPC standards. The tool calculates minimum pipe gradient to maintain self-cleansing velocity at design flow using Manning's equation with appropriate roughness coefficients for PVC, clay, and concrete pipe materials. Inspection chamber positioning at gradient changes, junctions, and maximum spacing intervals completes the drainage layout design.
