What Dynamita does
Dynamita S.A.S. is a French scientific-software company that builds process simulators for water and wastewater treatment, with company headquarters in Sigale, in the mountains near Nice. Its flagship product, SUMO, is a dynamic wastewater process simulator covering biological nutrient removal (nitrification, denitrification, biological and chemical phosphorus removal), biofilm and granular sludge reactors (MBBR, MABR, IFAS), SBRs, lagoons, clarifiers, aerobic and anaerobic digestion, greenhouse gas/N2O modeling, and integrated carbon footprint, energy, and cost calculations. The platform is built on an open process code architecture with a proprietary modeling language (SumoSlang), a numerical engine (SumoCore) supporting steady-state and dynamic simulation, and a Digital Twin Toolkit (DTT) exposing C/C++ and Python APIs with OPC UA connectivity for real-time plant integration. In February 2026, the company extended into potable, reuse (REUT), and ultrapure water via DYNAMIZU.

Dynamita product offering
Product offeringCore offering
Dynamita develops and licenses process simulation software for water and wastewater treatment plants. Its flagship SUMO platform performs dynamic, steady-state, and algebraic simulation of municipal and industrial treatment processes, supported by the proprietary SumoSlang language and a Digital Twin Toolkit for real-time plant integration. The company also released DYNAMIZU in February 2026, a dedicated dynamic simulator for potable, reuse (REUT), and ultrapure water applications.
Product overview
Dynamita offers a portfolio of specialized process simulation software centered around two core products: SUMO (wastewater process simulator) and DYNAMIZU (water-focused dynamic simulator). SUMO is the flagship wastewater process simulation platform supporting dynamic, steady-state, and algebraic simulation of municipal and industrial wastewater treatment plants. DYNAMIZU, launched in February 2026, is one of the first dynamic simulators dedicated to potable water, effluent reuse (REUT), and ultrapure water applications. The portfolio includes a Digital Twin Toolkit (DTT) providing Python and C/C++ APIs for external application development and real-time OPC UA connectivity. SUMO for Rent offers a cloud-based weekly rental option for intermittent users. Add-on modules extend SUMO capabilities in areas such as densified sludge modeling. All products share an open process code philosophy allowing users to build custom models. Dynamita also provides professional training services globally.

Dynamita competitors and assessment
Company assessmentRegional players
- Kurita Water Industries: Major Japanese industrial water treatment company (Takayuki Ohtsuki's former employer) that operates its own process modeling and digital water solutions. Becomes a relevant peer/customer profile as Dynamita expands into ultrapure and industrial water via Dynamita Japan and the Ohtsuki partnership.
Broad incumbents
- Bentley Systems (OpenFlows): Provides water and wastewater infrastructure modeling software (OpenFlows SewerGEMS, WaterGEMS, HAMMER) widely used by engineering consultants and utilities. Adjacent competitor to SUMO in the water-domain digital-twin stack, with much broader enterprise reach and bundled platform offerings.
- AVEVA (Schneider Electric): Global industrial software platform covering process simulation, digital twin, and plant operations. Broad incumbent that overlaps with Dynamita's Digital Twin Toolkit ambitions at large industrial water customers and could bundle water-process modeling into its PI System / CONNECT platform.
- Kemira (SIMBA#): Major chemistry supplier that bundles the SIMBA# wastewater simulator with its water-treatment chemicals and services portfolio. Competes with SUMO at municipal and industrial clients by offering the simulator as part of a broader chemistry-and-service contract.
Direct peers
- EnviroSim Associates: Developer of BioWin, a leading wastewater process simulator used by consulting engineers and utilities worldwide. Direct competitor to SUMO across BNR, sludge digestion, and integrated plant modeling, with comparable academic and engineering consulting customers.
- DHI: Developer of WEST (Wastewater Engineer's Software Tool), a mechanistic dynamic wastewater modeling platform. Direct competitor to SUMO in the activated sludge/BNR modeling space, with strong academic and municipal utility presence especially in Europe.
- Hydromantis Environmental Solutions: Developer of GPS-X, one of the most widely deployed dynamic wastewater process simulators in the municipal and industrial markets. Direct competitor to SUMO in activated sludge, BNR, and biofilm modeling with overlapping customer base of utilities and engineering consultants.
Emerging players
- Transcend: Provider of the Transcend Design Generator (TDG) automated engineering documentation platform for water and wastewater infrastructure. Became a Dynamita partner in October 2025, embedding SUMO inside TDG — a complementary rather than competing relationship that nonetheless overlaps in serving the same consulting-engineer buyer.
- USDOE NAWI / WaterTAP: US Department of Energy-funded open-source water treatment modeling platform. Listed by Dynamita itself as a complementary tool; emerging open-source alternative to proprietary simulators like SUMO that could pressure pricing in academic and budget-constrained utility markets.
- Forain S.r.l. (LESS): Italian software firm offering LESS, a wastewater treatment process simulator with biofilm and activated sludge modeling capabilities. Smaller-scale direct peer to SUMO serving a similar consulting-engineer and academic customer base in Europe.

Does Dynamita have an API?
Yes. Dynamita offers a Digital Twin Toolkit (DTT) providing APIs to the SUMO numerical engine. The C/C++ API is a low-level function API. The Python API includes sumon.py for direct connection to the numerical engine via the C/C++ API, and scheduler.py for connection through the SUMO scheduler. Additional Python tools include tool.py for extracting information from .sumo project files, dmqclient.py and dtcontrol.py for OPC communication helpers. A DTT license is required. SUMO also supports OPC UA connectivity (Windows only) for connecting to OPC servers and hardware. The JSON exporter utility extracts parameters, scenario inputs, and chart symbols into a .json file for easier Digital Twin setup. Developer documentation is at wiki.dynamita.com/en/home.
