Water utilities around the world are at a critical juncture. Climate change, urban growth and aging infrastructure are putting unprecedented strain on already limited and precious resources, of which, water is key. Research from the World Resources Institute’s Aqueduct Water Risk Atlas puts at least 50% of the world’s population, about 4 billion people, at high risk of facing water stress each year1. These risks are not theoretical or in the distant future - they are evidenced today through failing pipelines, service disruptions and escalating operational and maintenance costs.

This blog is part of our 'AI for Water' series, where we explore how artificial intelligence can transform water utilities. In this perspective, we delve into the practical applications of predictive AI and how it can address some of the water sector’s most pressing challenges, from aging infrastructure to operational inefficiencies.


The State of Play and Role of Predictive vs Generative AI

In Europe, systems built over a century ago are grappling with meeting modern infrastructure demands. In the United States, the American Society of Civil Engineers (ASCE) has consistently graded the nation's drinking water infrastructure at a "C-" level, indicating significant deficiencies. Further, in India, water demand is projected to double by 2030 due to population growth.

Despite these pressures, many water utilities still continue to rely on outdated systems that are costly, inefficient and vulnerable. Failure to innovate could mean widespread disruptions, and moreover, result in huge economic and social costs.

    Artificial Intelligence (AI) offers a way forward. If applied effectively, AI could revolutionize how water utilities manage limited resources and optimize operations. While much of the conversation today evolves around generative AI - a technology that creates content and has sparked debates around ethics and risks - predictive AI is a more promising solution, operating quietly in the background, delivering tangible results.


    Unlike generative AI, predictive AI has been around for decades and has matured significantly over the past 10-15 years. Its purpose is clear: to forecast, optimize and improve systems based on data-driven insights. What’s more, the risks associated with predictive AI are far less, making it a more practical and reliable solution for water utilities. And, it focuses on critical applications needed today like pipe condition assessment, forecasting future system states and optimizing resource utilization.


    With the urgency to act, now is the time to move from theory to practical application.

A Lifeline for the Aging Infrastructure Crisis

Aging infrastructure remains one of the most significant challenges for water utilities worldwide. A critical consequence is non-revenue water – treated water that is distributed but lost before it reaches customers due to leaks, theft or billing errors. This not only results in billions in lost revenue globally but also leads to waste of valuable energy and resources used to pump, treat, and distribute water, directly contributing to avoidable carbon emissions. The financial consequences add to billions in revenue lost across the globe. In Europe, an umbrella group of water suppliers, EurEau estimates that about 25% of all water distributed is lost, with nearly all of this attributed to leaky pipes2. While in the UK, this has led to a staggering 3 billion liters of water lost every day3. And in the US, ASCE's 2021 Report Card highlighted an estimated 6 billion gallons of treated water lost daily through aging and deteriorating pipes, costing utilities approximately $2.6 billion annually.

These losses are not only a financial burden but also a critical resource challenge, as utilities struggle to meet increasing demand amid climate pressures and growing urban populations. The sheer scale of water loss warrants urgent action to address aging infrastructure. Yet, traditional methods of repair and maintenance are often costly and too slow to implement. Furthermore, taking a reactive approach fails to prevent systemic issues or anticipate vulnerabilities. Instead, utilities must embrace smarter, more proactive strategies that tackle the root causes of water loss.


Predicting failures before they happen

Aging infrastructure is an issue that will only get worse unless we get smarter about how we manage it. Predictive AI enables utilities to quickly identify potential weak points in their networks, prioritize maintenance efforts and prevent failures before they occur. By leveraging real-time monitoring and advanced analytics, utilities can minimize water loss and secure their financial and environmental future.

In the UK, the High Speed 2 (HS2) project requires significant water utility and management efforts, including major asset diversions or rerouting,, flood protection and river management. These were supported by advanced analytics through Arcadis’ EDA platform, leveraging artificial intelligence (AI) and machine learning (ML) to ensure data-driven decisions in planning and execution.

In the US, Arcadis partnered with the San Antonio Water System to implement an AI-driven asset management system that analyzed variables such as pipe material, age and environmental conditions to predict failure risks. This proactive approach is helping the utility prevent costly disruptions and reduce water loss, enabling them to prioritize investments where they are most needed and extend the lifespan of critical infrastructure.


Accelerating intelligent and responsible infrastructure design

Intelligent water solutions can also support smarter infrastructure planning. Generative design tools allow utilities to simulate multiple design scenarios, incorporating resilience and efficiency into every option. These tools such as Arcadis’ Asset Generator, which is a cloud-based tool to automate the design and creation of 3D models and facilitates master planning in a GIS environment, speed up the planning and design process while enabling utilities to future-proof their investments, ensuring long-term viability.

Transforming Water Management and Service Delivery

Predictive AI is not just about leveraging advanced technology because of the ‘hype’ - it’s about accurately pinpointing and addressing long-standing operational inefficiencies and environmental challenges in water utilities. If used right, it can help utilities transform scattered data into actionable insights that drive efficiency, optimize resources and minimize risks.

So, who stands to benefit? Water Treatment and distribution system operators can leverage AI to better manage water age and energy use across their networks. Collection system and wastewater treatment plant operators can make informed operational decisions translating weather observations with AI into highly accurate flow forecasts. These forecasts allow assets to be brought online proactively and controls to be set at optimal points, maximizing treatment efficiency and minimizing spills.


Process and quality optimization beyond reducing outages

Reducing outages is one of many benefits of predictive AI, but the true potential lies in its ability to optimize operations and quality across the entire utility.

AI empowers utilities to:

 Anticipate weather impacts:

In Southern California, Arcadis implemented an AI-powered predictive modelling system that integrates machine learning with an advanced multispecies water quality model (built in Autodesk’s InfoWater Pro platform) to monitor disinfection byproducts (DBPs). Predicting potential spikes enabled the utility to adjust its processes in real time, achieving compliance while delivering better water quality to customers.


Proactively managing greenhouse gas emissions

Reducing greenhouse gas emissions is a pressing challenge for utilities today, particularly nitrous oxide (N₂O), which is 300 times more harmful than carbon dioxide (CO₂) and also contributes to ozone layer depletion. Unlike CO₂, N₂O emissions cannot simply be offset. This requires them to be addressed directly at the source, making their accurate prediction and management critical for utilities striving to meet climate goals.

Arcadis partnered with Welsh Water to implement an AI-powered system designed to accurately predict N₂O emissions. By collecting process data from six wastewater treatment plants (WWTPs) and feeding it into Cobalt Water’s AI (a machine learning-based platform), the system was able to to forecast N₂O emissions using operational data alone. The predictions were then corroborated with test hoods using N₂O sensors. The result was a phenomenal correlation of up to 90% accuracy between the AI model and physical measurements.

This breakthrough represents a significant advancement in wastewater treatment. Using only operational data, the AI system was able to predict and proactively manage one of the most harmful greenhouse gases. In the pre-AI era, such precision was unattainable. Now, utilities can take targeted actions to minimize emissions as part of their process optimization strategies, aligning with regulatory requirements, while delivering far better water quality for customers.


Overcoming Regulatory Complexities, Enhancing Compliance

As utilities embrace AI, the regulatory environment presents both challenges and opportunities. Governments and regulatory bodies across all regions of the world are increasingly scrutinizing AI to ensure ethical deployment, operational transparency and data security.

The European Union’s Artificial Intelligence Act, one of the most comprehensive regulations for artificial intelligence that came into effect from 1 August 2024, mandates stringent requirements for transparency and accountability. For water utilities, this means ensuring that AI models used for predictive maintenance or water quality forecasting are safe, transparent, traceable, non-discriminatory, environmentally friendly and overseen by humans. Similarly, while AI legislations across the U.S. is at various stages, over 30 states have some form of proposed and/or enacted legislation leading to strengthened cybersecurity measures for critical infrastructure to safeguard against data breaches and malicious attacks.

Integrating AI into water utilities often involves navigating these regulatory complexities. Arcadis conducted independent research in coordination with state regulatory agencies across the United States to understand their stance on AI adoption. Responses varied widely - some indicated that AI use is not explicitly addressed, while others advised that its implementation will require an engineering plan review due to the potential impact on treatment plant effluent quality. These regulatory nuances emphasize the importance of balancing innovation, responsible deployment and compliance.


Turning Compliance into a Competitive Advantage

Predictive AI can help utilities not just meet regulations but often exceed them.

While regulatory requirements may often seem burdensome, they also offer an opportunity for utilities to lead the way in ethical and transparent AI deployment. Predictive AI can act as a compliance enabler. For example:

Data-Driven Reporting:

Transparent AI systems demonstrate a utility’s commitment to ethical operations, building trust with stakeholders.

Preparing the Workforce for an AI-Driven Future

While AI holds great promise, it also presents a challenge: workforce readiness. Utilities are faced with a two-fold problem. On one hand, older workers are retiring at an increasing rate, leaving utilities struggling to fill critical positions. On the other, adoption AI requires a workforce that understands its capabilities and knows how to use it to maximize its potential.

The adoption of predictive AI is as much about people as it is about technology. Without the right workforce strategies, even the most advanced AI systems cannot deliver their full potential. Similar to how the pandemic accelerated the adoption of remote work, these pressures may normalize the use of AI to perform tasks that were once considered too risky or unconventional.

Investing in upskilling

Arcadis is working with utilities in Germany to develop targeted AI training programs. These initiatives ensure workers at all levels are upskilled and equipped with the right skills needed to integrate AI into their daily operations.

Empowering a new workforce dynamic

As older systems and work practices give way to AI-driven operations, utilities need a new breed of workers: who are not only familiar with water systems but also comfortable with data analytics and machine learning.
