SC1: Modern Optimisation for WDS

Short Course Title: From Best-Guess to Better Decisions: Modern Optimisation for Water Distribution Systems

Duration: 3 hours

Short Course Organizer: Prof. Dragan Savic FREng and Lydia Tsiami (PhD Candidate)

Instructors:

1. Prof. Dragan Savic FREng
2. Mark Morley, PhD
3. Lydia Tsiami (PhD Candidate)
4. Dennis Zanutto (PhD Candidate)
5. Christos Michalopoulos (PhD Candidate)

Description of the course:

Optimisation is a powerful ally for water professionals. It can deliver substantial savings and help balance multiple objectives in complex problems. It can support how utilities design networks, plan reinforcements operate their networks, but most of these approaches quietly assume a single “best guess” future. What happens when that future never arrives? Demand is uncertain, energy prices jump, cities grow, regulations tighten, assets deteriorate, and suddenly yesterday’s “optimal” solution starts to crack.

This short course explores how optimisation and modern decision-making strategies can move beyond single-scenario thinking. We look at how a few key modelling choices, namely the length of the planning horizon, the staging of decisions, and daily operations, interact with one another. We will explore how modern planning frameworks, including staged, robust and flexible approaches, can help systems perform better under uncertainty. We also discuss how optimisation can find its place in water utilities practice, rather than living only in research papers.

Participants will get an overview of optimisation in the context of water distribution networks, and see a range of formulations in practice, from classical approaches to more recent methods that explicitly consider uncertainty, staged decision-making and the role of operations. These ideas will be explored through simple, hands-on modelling examples in Python. We will also demonstrate a software platform tailored for water professionals and utilities, designed to make these optimisation approaches easier to apply in practice. Finally, we will briefly touch on modern developments such as agentic AI and how they might support decision-makers in exploring options and stress-testing plans.

Intended audience:

The course is aimed at both newcomers and practitioners with some optimisation experience who are curious about where the field is heading and how these ideas can be applied in real-world water distribution planning. Basic familiarity with Python and water distribution modelling is helpful.

SC2: AI for Water Professionals

Short Course Title: AI for Water Professionals

Duration: 3 hours

Short Course Organizer: Dr Elad Salomons, University of Haifa, Israel

Instructors:

1. Prof Mashor Housh, University of Haifa, Israel
2. Prof Lina Sela, University of Texas at Austin, US
3. Dr Elad Salomons, University of Haifa, Israel

Description of the course:

This short, hands-on course introduces water professionals to the practical use of artificial intelligence (AI) tools in everyday utility and engineering tasks. In just a few hours, participants will see how AI can make routine work faster, easier, and more insightful, without needing to be a programmer or data scientist. Using familiar datasets and examples from real-world water operations, the session demonstrates how AI can help analyze pump and system performance, detect anomalies in SCADA or AMI data, design a simple water distribution network, and its operation. Throughout the session, participants will use AI tools (mainly ChatGPT) directly to complete small, realistic exercises that mirror the daily challenges faced by water utility engineers, analysts, and managers. This introductory session is perfect for water-sector professionals curious about applying AI to data analysis, planning, and operational problem-solving, with no coding experience required.

The course is a condensed version of the full two-day AI for Water Professionals Workshop, which has already been delivered several times successfully to water utility professionals. The complete workshop provides in-depth, hands-on training in applying AI to data analysis, hydraulic modeling, and decision support. This abbreviated version focuses on selected examples and demonstrations, offering a practical introduction to how AI tools can be used to analyze water system data, support operations, and enhance efficiency. It’s designed for participants who want a focused, accessible overview of what AI can do for the water sector.

Intended audience:

This short course is designed for a diverse audience interested in the intersection of water management and artificial intelligence:

1. Water professionals with limited AI experience: engineers, analysts, and utility staff who want to understand how AI tools can make their daily work more efficient. The course focuses on practical, easy-to-use examples, with no programming or data science background required.
2. Students and early-career researchers: those studying water resources, environmental engineering, or related fields who wish to see how AI is applied in real-world water utility contexts. The course bridges the gap between academic learning and professional practice.
3. Trainers and facilitators: individuals or organizations interested in running their own full AI for Water Professionals Workshop. This short session provides an overview of the structure, materials, and teaching approach used in the extended two-day version, serving as a foundation for those who want to deliver similar training programs.

General notes:

• Each participant must bring a laptop.
• Participants are required to have a ChatGPT Plus subscription or an equivalent product. Most services allow you to register a premium account for a monthly fee and cancel it at any time.
• The workshop is limited to 25 participants.

SC3: Physics-informed DL surrogates

Short Course Title: A Practical Introduction to Physics-informed Deep Learning for Surrogate Models of Drinking Water Systems

Duration: 3 hours

Short Course Organizer: Dr. André Artelt, Bielefeld University, Germany

Instructors:

1. Dr. André Artelt, Bielefeld University, Germany
2. Inaam Ashraf, Bielefeld University, Germany
3. Luca Hermes, Bielefeld University, Germany

Description of the course:

Rapid urban population growth, among others, makes drinking water system analysis an increasingly challenging task. Often, simulators such as EPANET are used in various tasks, such as planning, state estimation, event diagnosis, etc. However, such simulators are computationally expensive and scale poorly in time and space, challenging the development of digital twins for improved system analysis. In this context, recent work highlights the potential of AI methods for building efficient surrogate models of the simulator that can be used as part of a digital twin.

In this training course, we provide the participants with the necessary knowledge of using physics-informed Deep Learning to develop high-fidelity surrogate models. The course will include many hands-on examples in Python and be split into three parts.

1. Recap of Machine Learning (ML) basics and foundations of (physics-informed) Deep Learning. A special focus will be on pre-processing strategies, evaluation metrics and procedures, incorporation of different types of physics, and hyper-parameter tuning.
2. Data generation for training and evaluating ML models, such as deep neural networks. We will discuss and demonstrate the selection and creation of appropriate benchmarks for building and evaluating the ML models. Most importantly, we will discuss scenario generation in Python, including how to break correlations and incorporate parameter uncertainties to ensure high fidelity of the final ML models.
3. A case study on a physics-informed Graph Neural Network (GNN) based hydraulic surrogate model. After an introduction to Graph Neural Networks (GNNs), we present and explain a hydraulic surrogate model based on physics-informed GNNs. In this context, we will discuss and demonstrate how such a surrogate model can be used in a digital twin for a variety of different tasks, such as state estimation from sparse sensor readings, and network rehabilitation.

Intended audience:

• Practitioners and researchers that are interested in exploring the potential of AI (i.e., Machine Learning and Deep Learning) for building surrogate models that can be used in digital twins.
• Basic knowledge of Machine Learning is required.

SC4: Digital Twin in action

Short Course Title: Using a well (or less well) calibrated Digital Twin to minimize impact of network disturbances.

Duration: 3 hours

Short Course Organizer: Prof Mirjam Blokker, KWR and Delft University of Technology, the Netherlands

Instructors:

1. Dr. Mark Morley, KWR, the Netherlands
2. Prof Mirjam Blokker, KWR and Delft University of Technology, the Netherlands

Description of the course:

During this workshop we will play out an incident in a Drinking Water Distribution Network (DWDN). The participants are asked to determine the location of the incident and tell us which actions to take (which valves to close and open, and at what time – taking into account a reasonable repair time). An overall score will be based on Customer Minutes Lost, minimum pressure and maximum water age.

This DWDN is simulated with two sources (with their own patterns of electric conductivity), stochastic demand patterns, specified pipe diameters, wall roughness and valve settings. From this, we have constructed a Digital Twin, which has deterministic demand patterns, and potentially a deviation in pipe diameters, wall roughness and valve status, as is the case in the real world. A selected number of sensor locations provide calculated time series of pressure, flow and electric conductivity.

Prior to the workshop (end of February 2026), the participants will receive the network model and time series of sensor data, which can be used to calibrate the model. During the workshop an incident (e.g. a pipe break) will be simulated. The participants are asked to determine the location of the incident and tell us which actions to take. We will then simulate these actions in the simulated DWDN (not in the digital twin) and determine an overall score based on Customer Minutes Lost, minimum pressure and maximum water age. The participants will work with EPANET Net3. We will also demonstrate with a real Dutch network model.

Participants are invited to (after the conference) co-author a paper, which will shed some light on the importance and best approach of calibration of a Digital Twin.

Intended audience:

We encourage participants to form teams of 2-5 people. A mix of hydraulic modellers, optimization and water utility experts may yield the best score.
