Aquanuity Releases AquaTwin Water Pro, World’s First and Only Multi-Species Modeling with Dispersion and Mass Conservation

Key Highlights

  • Allows for the consideration of multiple interacting species in the bulk flow and on the pipe walls.
  • Allows multispecies reaction with dispersion. In dead end regions, dispersion may play an important role in constituent transport.
  • New improved topological sort water quality routing algorithm with no mass loss or creation.
  • New Lagrangian Time Driven transport method (Rossman and Boulos 1996) as in EPANET 2.2 and provides mass balance report for all the RATE species.
  • Uses parallel computing (parallelization) with up to 60% faster run time.


Aquanuity, Inc., the leader in strategy-led simulation-powered water infrastructure digital twin software, today announced the release of AquaTwin Water Pro for ArcGIS Pro. The new extension extends the powerful water quality modeling capabilities of AquaTwin Water with the ability to model complex reactions between multiple chemical and biological species in both the bulk flow and at the pipe wall. It allows users the flexibility to model a wide-range of chemical reactions of interest, including, auto-decomposition of chloramines to ammonia, the formation of disinfection byproducts, biological regrowth, combined reaction rate constants in multi-source systems, and mass transfer limited oxidation-pipe wall adsorption reactions. It further substantiates Aquanuity’s steadfast commitment to delivering value-driven geocentric innovation to its customers.

“AquaTwin Water Pro continues our strategy of raising the bar and setting new standards in ArcGIS Pro-centric water infrastructure digital twin innovation,” said Paul F. Boulos, Aquanuity Chairman and CEO. “It allows users to model any system of multiple, interacting chemical species. And for the first time, users can now model dispersion in dead ends. We are thrilled to introduce this breakthrough digital solution to help water utilities better meet the needs of their growing customer base and best serve and protect their communities and ensure their systems meet State and Federal standards for safe drinking water.”
