This Manual describes the DC Water Design Extension Version 2.12.3.
This Document uses Terminology from ArcView and EPANET. Refer to the respective documentation for in-depth explanations.

Be sure to check the DC Processing Extension and the DC Sewer Design Extension which are also freely available. These extensions provide additional functionality that is very helpful. E.g. the DC Sewer Design Extension can be used to draw water network profiles. |
The DC Water Design Extension is an Extension to ESRI's ArcView GIS software. Starting with Versions 2.00 the DC Water Design Extension integrates the EPANET 2.00 hydraulic modeling software with ArcView. It allows to store, edit and retrieve EPANET hydraulic models including all options in ArcView. Also it's possible to run the EPANET hydraulic analysis from ArcView and load the results into the GIS.
An Elevation calculation tutorial has been added to the extension (the section called “Elevation Assignment from Spot Heights”).
When writing EPANET INP files, the
Statusfield of aPipethat contains "closed" will be set to "closed".
Bytecode Calculator byte numbering starts with 1 now instead of 0.
"Extract Model" allows to select models that should be extracted as well as the folder to which the models should be extracted.
Robustness improvements for "Extract Model", "Split Model" and "Merge Model".
Fixed bug in "Split Model" and "Extract Model" that could lead to feature duplication when elements are moved from zone to zone in split models.
A Thiessen Polygon tutorial (the section called “Demand Calculation using Thiessen Polygons”) has been added to the documentation.
Experimental writing of OptiDesigner files (the section called “Write EPANET File”).
New function to select economic diameters based on the velocity result (the section called “Set Economic Diameter”).
Critical bug fixes for "Load Results for Step ...", "Extract Model", "Merge Model" and "Split Model". The bug could result in involuntary changes to the original data.
Bug fixes for
DCWatDes.Bitcode.or()andDCWatDes.Bitcode.xor()functions.Improved "Bytecode Calculator" functionality (the section called “Bytecode Calculator”).
"Write Epanet File" collapses setting entries of valves to "closed" if they contain "closed".
"Extract Model" allows now to create one view per model (the section called “Extract Model”) and will extract demand junctions to a separate file if a field
HasDemandis found in the junction table..New "Enforce Data Model" option that allows to relax data model checks when editing networks (E.g. sewer or street networks). See the section called “Setup”.
"Select Connected Pipes" looks for "closed" as a substring rather than a closed string (If "Closed Valve" is selected).
Bitcodes became byte codes (strings) and can distinguish up to 255 zones.
New "Split Model", "Merge Model" and "Extract Model" functions in the Project GUI (the section called “Split Model”, the section called “Merge Model”, the section called “Extract Model”).
INP file import is handling virtual lines now. Function robustness has been improved and error messages are displayed in ArcView.
More robust "Create Missing Junctions" function.
Updated documentation
New installer interface.
Bug fixes for patterns, help file integration, result import.
Switched Documentation to DocBook. Documentation is accessible from DC Water Design Extension Menu now.
Fixed pattern export
The extension doesn't use the power_kw field of the pump table any more.
Bug fix for result import.
Better handling of curves and patterns.
Improved "Check Epanet model" functionality.
Basic skeletonization function.
Bug fixes for the "Create Missing Junctions" function.
Russian localizations (Thanks to Tom Chidley).
More Arabic localizations (Thanks to Maher Karim).
Bug fixes for emitterexponent and demandmultiplier export to EPANET INP files.
Added emitter coefficient as to the junction class.
Updated documentation.
Completely new and much faster EPANET INP import based on the EPANET toolkit and shapelib. Import function still incomplete: Attributes are omitted.
French and Arabic localizations.
Bug fixes for one-node themes, snapping radius, pipe splitting, popup menus and exporting.
Fixed several problems when the view contained raster themes.
EPANET INP import: Fixed junction import, improved performance. Import function still incomplete.
Customizable timeout and other improvements for external command calls (Thanks to Melissa Henderson of Lockwood, Andrews & Newnam, Inc.).
Check EPANET model checks now for pipes that are shorter than the snapping radius.
Import of EPANET binary result files.
Preliminary support for importing EPANET INP files: Importing pipes and junctions.
Added function to automatically add the theme fields required by the data model.
EPANET result import works now without MySQL.
Check EPANET Model provides more checks now and is much faster.
"Create Missing Junctions": Add additional junctions to make sure that the network topology is sane.
Updated Documentation.
Checking for spaces in path names which are not allowed.
Customizable backdrop map resolution.
Support for patterns.
More checks while writing EPANET files.
Various bugfixes (see
ChangeLogfor the details).
Updated Documentation.
Support for Backdrop Maps (Thanks to Roland Salgado, the section called “Write EPANET File”).
Create Zones From SOV Controls (the section called “Create Zones from Controls”).
Bugfix for coordinate systems using decimal feet (Bug reported by Arnold Strasser).
