- Drainage Design Software



Storm and foul networks are laid out, manipulated and edited automatically; sensing manhole and pipe locations, applying design rules, cover levels and chainage locations appropriately. The most comprehensive drainage layout package available - and the only one that fully integrates with Causeway Flow for full hydraulic network analysis.
