Build modelling apps like epanet-js

Run hydraulic analyses, or create custom frontend and server-side applications using the EPANET engine with JavaScript.

epanet-js toolkit is a javascript library for engineers, developers and academics to simulate water networks. The toolkit allows you to run and share hydraulic analyses, or create custom frontend and server-side applications using the OWA EPANET engine.

The epanet-js toolkit is a full port of version 2.2 OWA-EPANET Toolkit in Typescript, providing access to all 122 functions within the toolkit.

The JavaScript library is for engineers, developers and academics to run and share hydraulic analyses or create custom front end or server-side applications.

The epanet-js toolkit allows you to simulate water distribution networks in javascript using the EPANET engine. If you’re not familiar with either water modelling or EPANET, have a read through what is water modelling.

Both the epanet-js toolkit is MIT licenced, which allows the library to be used in comerical applications. The hydraulic engine used within the epanet-js library is OWA-EPANET 2.2, which is also MIT licenced, with contributions by the following authors.

The source code for the project is hosted on GitHub and external contributions are welcome! You can learn more about the development process, our roadmap and also visit the Github repo.

To get started in using the epanet-js toolkit in your applications, follow the instruction below to install the library. To see complex applications built on top of epanet-js, check out the showcase. If you have a project which uses epanet-js and want to share it, please let us know!
