DRAINS is a Stormwater Drainage System design and analysis program.

DRAIN  provides a much enhanced successor to the ILSAX program which has been widely used for urban stormwater system design and analysis in Australia and New Zealand. It is co-developed by Watercom and Dr. Geoffrey O'Loughlin, developer of the ILSAX program.

DRAINS provides a Windows graphical interface. Users can draw drainage system components such as sub-catchments, pits, pipes and overflow routes. Right clicking on a component will display a pop-up menu from which you can choose to enter data or view results in various formats. Design rainfall patterns can be entered separately. Results such as run-off hydrographs are displayed graphically and can be pasted into other Windows programs such as spread sheets and word processors.

The DRAINS program will perform hydraulic grade line analyses, design stormwater drainage systems and produce summary graphs and tables, and pipe long section drawings.

When used in conjunction with Autodesk Land Desktop or Civil 3D + Advanced Road Design, DRAINS completes the design / analysis / drafting cycle.

1. Use Land Desktop/Civil 3D + Advanced Road Design to determine water catchment areas and design pits and pipes
2. Export this data to DRAINS and perform analysis
3. Export analysis results to Land Desktop/Civil 3D + Advanced Road Design - and see your design automatically update!
