For Rivers, For Sewers, For Stormwater
Modules: xp2D, xpviewer, RTC

xpswmm is a comprehensive software package for modeling stormwater, sanitary and river systems. xpswmm is used by scientists, engineers and managers to develop link-node (1D) and spatially distributed hydraulic models (2D). It simulates natural rainfall-runoff processes and the performance of engineered systems that manage our water resources.

xpswmm incorporates data to facilitate design for Malaysian conditions. xpswmm software  among software recommended in Urban Stormwater Management Manual for Malaysia (Manual Saliran Mesra Alam Malaysia). 

This comprehensive software suite provides fast and intuitive tools to size new drainage structures including closed conduits of any shape, natural sections, channels, on-site detention (OSD), detention ponds and sewer networks.

xpdrainage is a sustainable drainage design package for use by landscape architects and civil engineers. Create new designs with both traditional pipes and pits/manholes combined with LID/SuDS/WSUD elements.

xpdrainage walks the user through the entire drainage design process, from conceptual design to water quality analysis to hydraulic flow analysis. The design is built upon the base map of the site and can include connected drainage systems such as bio-retention, ponds, swales and permeable paving. Handy calculators within the program size individual drainage systems and the analysis lets you know how well the whole design will control flows and pollutant removal. Fully-engineered drainage designs can then be exported back to the base-map or CAD program.
Functions include:
  • Private or commercial drainage design
  • Sustainable design for WSUD/SuDS/LID

psite3D is a revolutionary 3D site and road design software package built by engineers for engineers. The suite offers advanced road and site engineering with an easy-to-use interface and powerful automated design functions. It allows for quick and easy production of site and road layouts including complex junctions and roundabouts. It provides full control of very rapid 3D views of all aspects of your designs – above and below ground.

xpsite3D takes you from conceptual layouts through to fully engineered models and drawings in a way that is intuitive to design engineers and CAD professionals. Its inbuilt engineering intelligence allows you to create accurately engineered surfaces and volumes, which results in excellent productivity gains. But it gives even more benefit for the inevitable design reworks: when you move or modify any part of the roadway, the dimensions of the connected objects are adjusted automatically. The ease of use of the suite means designers can retain control of their road and site design rather than relying on others to interpret their designs into other software packages.

Functions include:

  • Intuitive 2D to 3D layout automation

  • Easy to us design tools

  • Building Information Modeling (BIM)

  • Automated junctions and roundabouts

  • Customized channel design

  • Grading tools

  • Earthwork & surface tools

  • Utility layout and clash detection

  • Output of full engineering drawings

  • Schedule of works

All the advanced features you need in a low-cost, unbelievably versatile program

There has never been a more comprehensive, powerful, all-in-one software solution that provides an easy-to-use and intuitive user interface for digitizing, geographic referencing, reprojection, tiling, and mosaicking. Didger solves the problem of combining data files in different coordinate systems, by providing extensive tools to transform the data into one cohesive coordinate system. You can use Didger to precisely convert paper maps, graphs, aerial photographs, or any other plotted information into a versatile digital format that you can use with other software. Didger can create new maps from the ground up or edit any map, drawing, image, or data set imported into it. 

A Powerful and Innovative Well Log and Borehole Plotting Program for Geoscientists

Strater is a well log and borehole plotting software program that imports your data from a multitude of sources (database files, data files, LAS files, ODBC, and OLE DB data sources). Strater provides innumerable ways to graphically display your data. All the logs are fully customizable to suit your needs. Design and save template and scheme files to make log creation efficient and consistent, create multi-page continuous logs, and quickly display new borehole logs. Utilize the header and footer panes to store all the information about the logs, such as well number, driller, location, method, company name, and company logo. The flexibility Strater offers is unparalleled. Strater is written for use with Windows 98, Me, 2000, and XP.

Water supply software

Waterworks combines the efficient algorithms of WATER with the spreadsheet capabilities of Excel for Windows to provide a complete modeling tool for water distribution systems.

Examine what if questions by simply changing a value in your spreadsheet and rerunning the analysis. For example, check if a booster pump will improve pressure for fire flow protection at a given location, or see how the addition of a pressure sustaining valve will affect the flows upstream. View the results in the spreadsheet or in a graph.
