The PIPES++ program is an extended version of the PIPES program and is intended for analysis of larger town water supply systems where the user is interested in monitoring reservoir levels, pump operating times etc over an extended time period (eg 24 hours) with system demands varying with time. It also includes water quality simulation which can be used to predict how chlorine and fluoride concentrations vary with time throughout the network.
DRAINS is a Stormwater Drainage System design and analysis program. It 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.
The demo versions of the programs are limited to a maximum of 5 pipes. There is no limit to the size of network which the full programs will analyse. The only limit might be imposed by the amount of RAM in your computer. However, as a machine with 4 MB of RAM can handle thousands of pipes it is most unlikely that your network will be too large for your machine.
Like the PIPES programs, 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 runoff hydrographs are displayed graphically and can be pasted into other Windows programs such as spread sheets and word processors. A demo version of the DRAINS program is available for download.
The DRAINS program will perform hydraulic grade line analyses, design stormwater drainage systems and produce summary graphs and tables, and pipe long section drawings. The movie shown above is an animation produced by DRAINS after an analysis using the unsteady flow engine.
