INP format is the native format for EPANET, a public domain, water distribution system modeling software package developed by the United States Environmental Protection Agency (EPA).  Water Supply and Water Resources Division. It performs extended-period simulation of hydraulic and water-quality behavior within pressurized pipe networks and is designed to be "a research tool that improves our understanding of the movement and fate of drinking-water constituents within distribution systems".    INP describes networks and does not store projection information.


The Manifold INP dataport is designed to extract tabular and other network information from an INP file.   The current version focuses on network nodes, not on the pipes between them.



To import from INP format:


  1. Choose File-Import from the main menu.

  2. In the Import dialog browse to the folder containing data of interest.

  3. Double-click the file ending in .inp for the data of interest.

  4. Many tables and some drawings will be created.



We can double-click on drawings or tables that are created to view them.   


This particular drawing shows the nodes in the Net3 example network for EPANET.  It is not georegistered and has no coordinate system assigned.  By default, we can assign it a Pseudo Mercator projection, which is meaningless other than to provide a coordinate system for the node points.
