Despite XP Software's strong commitment and investment to Research and Development, the software remains a price competitive software modeling package that provides all the major hydrology methods to allow you to predict your stormwater runoff, sanitary wet weather infiltration and inflow and dry weather flows.

XP-SWMM is a dynamic unsteady flow model rather than a steady state, standard step model. Our program is therefore capable of delivering results far more accurately and closer to real life than a steady state model will be able to accomplish.

The software provides a fast solution for analyzing the design of the most complex hydraulic networks including loops, tidal inflows, hydraulic structures, regulators, multiple time varying boundary conditions and distributed storage structures.
