ONE CONNECTED PLATFORM

Where engineering
comes together.

Most tools teach one piece of the system. NUOC.SI helps you explore how water, equipment, logic, and decisions affect one another.

01 / 03

Model the physical world

Build a connected network of pumps, tanks, pipes, valves, and treatment stages. Explore flow, pressure, storage, and changing demand.

Explore systems
02 / 03

Program the controls

Work with PLC logic, device I/O, HMI screens, and SCADA communications. See how control decisions change the physical process.

Try PLC and HMI
03 / 03

Test the consequences

Change operating conditions, introduce faults, replay responses, inspect trends, and compare simulation evidence over time.

FROM IDEA TO SYSTEM

Don't just read
the diagram.
Build it.

Start with a ready-made facility or create your own. Follow the same connected chain from equipment to controls to measurable results.

01

Design the process

Place components and connect the hydraulic, electrical, and communications paths.

02

Make it respond

Configure controllers, author logic, and operate through simulated HMI.

03

Learn from the results

Observe conditions, diagnose faults, and review the evidence behind an outcome.

BEYOND A SNAPSHOT

What happens
after hour one?

Simulation is more useful when the effects have time to appear. Explore extended-period scenarios and inspect how demand, storage, pump operation, pressure, and controls interact.

Students & curious engineers

Connect theory with visible behavior using guided examples and hands-on experimentation.

Controls & automation learners

Trace the chain from field signals and PLC logic to SCADA screens and device responses.

Water system professionals

Explore operational scenarios and ask better questions before drawing conclusions about real facilities.

THE DETAILS

Questions,
answered.

Understand what the platform is built to do and where its boundaries are.

Is NUOC.SI an actual water utility control system?

No. NUOC.SI is a browser-based educational simulator using fictional equipment and simulated signals. It does not control real water infrastructure or connect to operational PLCs or SCADA networks.

Do I need to install engineering software?

No installation is required for the browser-based workspace. Open the Studio to explore prebuilt scenarios or start a new design.

Does it model real engineering physics?

The Studio uses an EPANET-based hydraulic model alongside simulated PLC and equipment behavior. Water treatment and other processes use simplified educational approximations. Results need calibration and independent verification before real-world engineering use.

Can I test a full day of operation?

Yes. The engineering studio includes extended-period, 24-hour analysis with scenario results. Performance depends on the model and device running the simulation.
