For training new water treatment plant operators, the “best” operator training simulator (OTS) is usually the one that most closely matches your actual plant, SCADA/HMI, equipment, alarms, and operating procedures. A simulator with realistic graphics but inaccurate process behavior will not prepare operators for real events.
My shortlist:
| Simulator | Best fit | Recommendation |
|---|---|---|
| Hydromantis SimuWorks | Municipal drinking water and wastewater plants | Best overall fit for most water utilities |
| AVEVA Operator Training Simulator | Large, highly automated plants needing SCADA/DCS realism | Best for control-room replication |
| Yokogawa Electric Corporation OmegaLand OTS | Plants using Yokogawa automation | Excellent high-fidelity option |
| Jacobs Replica for Water | New plants, digital twins, commissioning | Strong for design + startup + training |
Hydromantis AVEVA Jacobs## My first choice for most water treatment plants: Hydromantis SimuWorks
SimuWorks is specifically designed for water and wastewater operations. It is often described as a “flight simulator” for treatment plants because it uses dynamic process models rather than only simulating button clicks. It can be customized with plant-specific data, graphics, and scenarios.
It is particularly good for teaching:
If your main goal is control-room qualification, especially at a large facility with sophisticated automation, I would look closely at AVEVA OTS. It combines dynamic process simulation, control-system emulation, and replicated operator interfaces so trainees can practice in an environment similar to the real control room.
This is especially valuable when you want operators to practice:
For smaller utilities or initial operator familiarization, Water Simulation Lab provides a browser-based simulated treatment plant with HMI screens, alarms, trends, and operating scenarios. It is useful as an introduction, but it is not the same as a plant-specific digital twin.
A serious operator simulator should include:

| Simulator | Best fit | My assessment |
|---|---|---|
| Hydromantis SimuWorks | Municipal drinking-water or wastewater plants | Best water-specific choice |
| Schneider Electric EcoStruxure OTS / AVEVA OTS | Plants wanting a realistic replica of their control room | Best for SCADA/control-room realism |
| Jacobs Replica for Water | Utilities wanting a broader digital twin + operator training platform | Very interesting for new/modern plants |
| Water Simulation Lab | Smaller utilities and entry-level operator training | Best low-cost/easy-start option |
| Yokogawa OmegaLand OTS | Large/complex industrial facilities | Excellent, but potentially more than a municipal plant needs |
For a conventional municipal water or wastewater facility, SimuWorks is the first vendor I would investigate. Hydromantis specifically designed it as a "flight simulator" for water and wastewater plants. It can use actual plant data, plant graphics, customized interfaces, and dynamic process models.
The important distinction is that operators can practice cause-and-effect, rather than simply clicking through a training course:
That is exactly where an OTS provides value: you can deliberately create situations that would be unsafe, expensive, or impossible to reproduce on the live plant.
I'd look closely at Schneider Electric EcoStruxure Operator Training Simulator (formerly AVEVA OTS). Schneider describes it as allowing operators to train in an environment identical to the control room, with accurate plant simulation models.
This becomes especially attractive if your plant already uses Schneider/AVEVA control technology.
Jacobs' Replica for Water is particularly interesting if you're building, expanding, or modernizing a facility. It combines a high-fidelity digital twin of water/wastewater hydraulics, controls and treatment processes with automation testing and operator-readiness training.
For a municipal drinking-water plant, my preference would be:
Actual plant model + actual SCADA screens + instructor-controlled scenarios + operator scoring/debriefing.
The software brand is secondary to getting those pieces right.
I'd require the vendor to demonstrate a scenario such as:
"Raw-water turbidity suddenly increases, one chemical pump fails, a filter begins loading rapidly, and the operator must recognize the alarms, diagnose the problem, adjust the process, and return the plant to stable operation." If the simulator can realistically reproduce that scenario using your plant's equipment, controls and SCADA, you're looking at the right class of system.
If you give me your plant type (drinking water vs. wastewater), capacity (MGD), SCADA platform (Ignition, AVEVA/Wonderware, VTScada, Rockwell, Siemens, etc.), and approximate training budget, I can narrow this down to 2–3 specific vendors and compare likely implementation cost, training capabilities, and pros/cons.
When it comes to training new plant operators (and sharpening the skills of veteran staff), the "best" operator training simulator (OTS) depends on whether you are focusing on **drinking water treatment** or **wastewater treatment** , as well as whether you want a generic training environment or an exact digital twin…

For new operators at a municipal drinking-water or wastewater treatment plant, I would not choose a generic “OTS” just because it has impressive graphics. The best simulator is one that reproduces your actual process, SCADA/HMI, alarms, control logic, and abnormal operating procedures.
| Simulator | Best fit | My take |
|---|---|---|
| Hydromantis SimuWorks | Municipal water & wastewater | Best overall choice if process understanding and realistic water-treatment behavior are the priority |
| Schneider Electric EcoStruxure OTS / AVEVA OTS | Large, highly automated plants | Best for control-room training when you want the simulator to look and behave like the actual SCADA/DCS |
| TSC Simulation OTS | Custom/high-fidelity training | Excellent if you want sophisticated scenarios, multiple trainees, and potentially 3-D field-operator training |
| Waterversity | Training/onboarding and qualification | Interesting newer option for water-specific simulated facilities and competency-based training |
| Water Simulation Lab | Low-cost/basic onboarding | Useful browser-based option, but considerably less capable than a plant-specific digital twin |
Why I put SimuWorks first: it is specifically built around water and wastewater treatment rather than adapting an industrial-process simulator. Hydromantis describes SimuWorks as a “flight simulator” for water/wastewater plants, with dynamic models, customized operator interfaces, plant data, and customized scenarios.
If you're training someone who has never operated your plant, I'd want the simulator to let them practice things such as:
The simulator should then score what the trainee actually did, not simply show an animated plant.
I'd seriously consider EcoStruxure Operator Training Simulator. Schneider says it allows operators to train in an environment identical to the control room and uses accurate plant simulation models. AVEVA's OTS similarly combines dynamic process simulation with an emulated control system and replicated interfaces.
This changes my recommendation. I'd strongly favor a plant-specific digital twin/OTS that can be connected to the actual PLC/SCADA, because you can use it for:
For example, Jacobs' Replica for Water specifically models hydraulics, controls and treatment processes and can connect to HMI screens for operator training and control-system testing.
If you tell me (1) drinking water or wastewater, (2) plant capacity in MGD, (3) your SCADA/PLC platform—e.g. Allen-Bradley, Siemens, Schneider, Wonderware/AVEVA—and (4) the major treatment processes, I can narrow this down to 2–3 vendors and give you a practical procurement comparison, including what I would put in the RFP and what questions to ask during the vendor demos.

Key Considerations for Your Decision
To help narrow down the ideal platform, could you share:
If your goal is to **train new operators for an actual drinking-water or wastewater treatment plant**, I would prioritize a **plant-specific dynamic simulator** over a generic “water treatment game” or SCADA-only training package. ### My top choices | Simulator | Best for | My take |
If your goal is to train new operators for an actual drinking-water or wastewater treatment plant, I would prioritize a plant-specific dynamic simulator over a generic “water treatment game” or SCADA-only training package.
| Simulator | Best for | My take |
|---|---|---|
| Hydromantis SimuWorks | Municipal water & wastewater | Best overall choice |
| AVEVA Operator Training Simulator | Large/complex plants with sophisticated SCADA/DCS | Best for control-room realism |
| Yokogawa OmegaLand OTS | High-fidelity industrial plants | Excellent, but often more than a municipal utility needs |
| Water Simulation Lab | Low-cost introductory training | Good supplement, not my first choice for full operator qualification |
| ANDRITZ OTS | Industrial water/effluent treatment, particularly alongside ANDRITZ equipment | Strong if your plant already uses their automation/process systems |
This is the one I'd investigate first for a municipal treatment plant. Hydromantis specifically describes SimuWorks as a “flight-simulator for water and wastewater treatment plants.” It uses dynamic models and can be customized around the actual plant, including plant graphics, operating data, and training scenarios.
That's important because a new operator needs to learn things like:
A simulator that behaves like your plant is vastly more valuable than one that simply teaches generic water-treatment concepts.
AVEVA's OTS combines dynamic process simulation with control-system emulation and replicated operator interfaces. It is designed to reproduce the look and behavior of the actual control environment and supports instructor-created scenarios and performance tracking.
I'd lean toward this if you have a large, highly automated facility and want the simulator to be very close to the actual control-room experience.
OmegaLand is another high-fidelity option. Yokogawa emphasizes reproducing actual plant behavior and using the same DCS/SIS/interface environment, with training for startup, shutdown, normal operations and abnormal situations.
It's particularly attractive if your control system is already in the Yokogawa ecosystem.
This is interesting for initial onboarding because it is browser-based and provides simulated HMI screens, alarms, trends and scenarios covering a water-treatment process.
I would consider it a training supplement, however, rather than the primary simulator for qualifying operators on a specific plant.
If you told me, “We have a municipal plant and we're hiring several inexperienced operators; give me one recommendation,” I'd start with Hydromantis SimuWorks and request a demonstration using a model of our actual process.
The critical requirement isn't the brand. It's whether the vendor will build a simulator that reflects:
Your process → your equipment → your SCADA/HMI → your alarms → your SOPs → realistic failures → measurable operator performance.
I'd also require the vendor to demonstrate at least these scenarios before purchasing:
One particularly important point: don't let a vendor sell you a simulator that is essentially an animated SCADA screen. The underlying dynamic process model is what makes an OTS valuable. The operator's actions should actually change the simulated chemistry, flows, levels, pressures, filter condition, etc.
If you tell me (1) drinking water vs. wastewater, (2) plant size in MGD, (3) your SCADA platform—Ignition, AVEVA, VTScada, Rockwell, Siemens, etc.—and (4) roughly what you want to spend, I can narrow this to 2–3 specific systems and compare likely cost, implementation time, and training capabilities.
If your goal is **hands-on training for new operators at an actual water/wastewater treatment plant**, my first choice would be **Hydromantis SimuWorks**—especially if you want the simulator to behave like *your plant*, rather than simply teaching operators how to use a generic control system. ### My ranking |…
If your goal is hands-on training for new operators at an actual water/wastewater treatment plant, my first choice would be Hydromantis SimuWorks—especially if you want the simulator to behave like your plant, rather than simply teaching operators how to use a generic control system.
| Simulator | Best for | My take |
|---|---|---|
| Hydromantis SimuWorks | Water & wastewater treatment | Best overall for a municipal treatment plant |
| Schneider Electric EcoStruxure OTS | High-fidelity control-room/operator training | Best if your plant uses Schneider/AVEVA automation |
| Yokogawa OTS / OmegaLand | High-fidelity DCS/process operations | Excellent for complex industrial treatment facilities |
| Honeywell UniSim | Process-industry training | Very strong, but less water-specific |
1. Hydromantis SimuWorks — my pick for water/wastewater
SimuWorks is specifically built as a "flight simulator" for water and wastewater plants. It can use a site-specific calibrated process model, actual plant data, and an interface customized to resemble the plant's SCADA system. Operators can practice normal operation as well as deliberately induced problems without affecting the real facility.
That's particularly valuable for new operators because you can create scenarios such as:
Its advanced version can use dynamic models and customized SCADA-like interfaces, rather than merely being a static training program.
2. Schneider Electric EcoStruxure Operator Training Simulator
I'd put this ahead of SimuWorks if your primary objective is training operators on the actual control-room environment and your facility is built around Schneider/AVEVA systems. Schneider describes its OTS as reproducing the control-room environment while using accurate process models.
3. Yokogawa OTS / OmegaLand
A very good choice for sophisticated process facilities. Yokogawa's OTS provides a virtual plant where operators can practice offline throughout the plant lifecycle, including inexperienced operators learning the process before startup.
I would not choose a simulator solely because it has nice graphics. For operator competency, the most valuable system is one where:
operator action → realistic process response → alarms/trends change → operator diagnoses problem → operator takes corrective action → instructor can score the response.
Ideally, the simulator should reproduce your actual SCADA/HMI screens, tag names, control logic and operating procedures, while the underlying process model behaves like the real plant.
So if you tell me (1) drinking-water or wastewater, (2) approximate plant size/capacity, (3) your SCADA/PLC/DCS platform—e.g. Rockwell, Schneider, Siemens, Ignition, etc.—and (4) your budget range, I can narrow this down to the 2–3 systems I'd actually put on an RFP, including approximate implementation complexity and what I would require in the vendor demo.
