The water and wastewater industry is an essential part of society, responsible for providing safe drinking water and managing wastewater to ensure public health and environmental protection. However, the rise of digitalization and operational technology (OT) integration has introduced significant cybersecurity risks. As the sector becomes more interconnected, the threat landscape expands, leaving water and wastewater utilities vulnerable to cyberattacks that could compromise safety, disrupt services, and cause substantial financial loss.
Why is OT Cybersecurity Critical for Water & Wastewater Systems?
In today’s digital world, OT is essential for optimizing the operations of water and wastewater facilities. However, the convergence of Information Technology (IT) and OT creates new vulnerabilities that cybercriminals are increasingly exploiting. These cyber threats have grown more sophisticated, especially with the rise of AI-powered attacks targeting critical infrastructure like water purification plants and wastewater treatment facilities.
Water and wastewater utilities often struggle with limited resources, making it difficult to implement comprehensive cybersecurity strategies to protect critical assets. As a result, cybersecurity has become a pressing concern in the sector, especially with the increasing reliance on remote access and automated systems for operational efficiency.
Key Cybersecurity Challenges in the Water & Wastewater Industry
Lack of Asset Visibility: Many water and wastewater utilities operate geographically dispersed facilities. With an expanding infrastructure, utilities often lack full visibility into their OT assets, making it difficult to detect potential vulnerabilities and mitigate risks.
Remote, Unmanned Facilities: A significant number of water and wastewater facilities are unmanned, and operations are often managed remotely by employees or third-party vendors. This opens the door for unauthorized access, especially if security protocols are not enforced properly.
Regulatory Compliance: Water utilities must comply with federal regulations like the U.S. Environmental Protection Agency’s (EPA) mandates under the Water Infrastructure Act (AWIA). These regulations require a detailed understanding of OT networks to ensure security and resilience assessments are met.
Consequences of Cyberattacks on Water & Wastewater Infrastructure
Cyberattacks on water and wastewater systems can have disastrous consequences. From ransomware attacks to insider threats, the risks of a breach are growing every day. A successful attack could contaminate water supplies, disrupt services, and cause significant public health and environmental hazards. For instance, in 2021, a cyberattack on a water utility in Florida attempted to manipulate the chemical levels in the water supply, potentially endangering public health.
Moreover, the operational consequences can be severe, as such attacks could lead to downtime, financial losses, and a loss of public trust in the water supply system.
How to Protect Water & Wastewater Systems from Cyber Threats
To safeguard critical infrastructure and ensure operational continuity, water and wastewater utilities need a robust OT cybersecurity strategy. Here are the key cybersecurity measures to implement:
Real-Time OT Asset Monitoring: It is vital for water utilities to identify and monitor every asset connected to the OT network in real time. Cybersecurity platforms that offer asset discovery and continuous monitoring are essential to detect vulnerabilities early and prevent unauthorized access.
Network Segmentation & Access Control: Water and wastewater systems should implement strict network segmentation to limit lateral movement by attackers. By controlling access, utilities can ensure that only authorized personnel and vendors can access critical systems.
Compliance with Industry Standards: Ensuring compliance with regulations like AWIA is essential. This involves conducting risk and resilience assessments and implementing solutions to meet these mandates. Compliance ensures that water utilities follow best practices and maintain the necessary security controls.
AI-Powered Cybersecurity Solutions: As the threat landscape evolves, AI-powered cybersecurity solutions can help detect emerging threats and anomalous behaviors in real time. AI can analyze vast amounts of data to identify patterns and predict potential risks, which is crucial for early detection and response.
Incident Response and Recovery Plans: Water and wastewater utilities should develop comprehensive incident response plans to quickly mitigate the damage in case of a breach. These plans should include defined steps for recovery, communication strategies, and measures to prevent future attacks.

Future of Cybersecurity in Water & Wastewater Systems
The water and wastewater industry is at a pivotal moment, where it must enhance its cybersecurity posture to keep pace with the evolving threat landscape. As operational technology continues to grow, so does the attack surface for cybercriminals. By implementing comprehensive OT cybersecurity solutions, water utilities can protect their critical infrastructure, ensure the safety of the public, and meet regulatory requirements.
With AI-powered solutions, real-time monitoring, and secure access controls, water and wastewater systems can build resilience against cyber threats and maintain the integrity of their operations. The time to act is now, as the water sector faces mounting pressures to safeguard its vital infrastructure from increasingly sophisticated cyber threats.
