State Seeks Public Input on New Reporting Rules and Regulations for Water Sector

New York State took first steps toward mandating cybersecurity standards for water and wastewater systems, a critical infrastructure sector increasingly a source of cyber defender anxiety and a mounting list of attacks.
Governor Kathy Hochul said Tuesday the state seeks public comment on proposed “nation-leading cybersecurity minimum standards” to help local systems defend against escalating threats from foreign adversaries and cybercriminals. Draft rules show the state targeting community water systems serving more than 3,300 people, with some components only affecting systems serving at least 50,000 residents. Among the proposals for water systems are incident reporting within 24 hours, regular training and vulnerability assessments. Wastewater systems would be required to implement access controls, multifactor authentication and incident response plans.
The state also announced a $2.5 million cyber grant program dubbed “Strengthening Essential Cybersecurity for Utilities and Resiliency Enhancements,” or SECURE, dedicated to the water and wastewater sector. The program is set to offer competitive grants to fund risk assessments and hardening efforts aligned with the proposed rules, helping systems strengthen cybersecurity, boost resiliency and ensure clean water delivery.
Hochul said the new regulations and grant program aim to help “under-resourced entities modernize for a digital age.” The proposed guidance was developed through a multi-agency process and includes cybersecurity rules from the Departments of Health and Environmental Conservation for water and wastewater systems, along with parallel proposals from the Department of Public Service for utilities and cable companies.
Cyberattacks on the nation’s water systems have raised concerns in recent years, including a 2024 breach at the largest regulated water and wastewater utility in the U.S. serving over 14 million people across more than a dozen states and 18 military installations. Hackers have yet to affect water quality and industry experts point to the existence of fail-safe mechanisms. But no one disputes that digitization has exposed water and wastewater systems to cyberthreats once unthinkable for a critical infrastructure sector dominated by images of reservoirs and pipes (see: Critical Infrastructure Leaders: Threat Level Remains High).
Water professionals say their sector has little choice but to incorporate remote network access into their operational technology stack, whether because of monetary pressure to outsource technical support or because modern equipment requires it for maintenance and updates. Standard guidance is to keep OT isolated from the IT network, but what may start out as carefully segmented networks over time can easily drift into unmonitored connections.
The Biden administration moved to integrate cybersecurity into routine water system safety assessments but reversed course after a federal judge blocked the effort following a lawsuit by multiple state attorneys general. The push also drew opposition from industry groups, eventually prompting the EPA to abandon the mandate and instead urge states to voluntarily review local cybersecurity programs (see: US EPA Nixes Cybersecurity Assessments of Water Systems).
Among the measures New York proposes is for all publicly owned treatment works to implement baseline controls aligned with the six core functions in the National Institute of Standards and Technology cybersecurity framework 2.0: govern, identify, protect, detect, respond and recover.
Most water and wastewater systems would need to meet strict cybersecurity requirements by 2027 while utilities regulated by the Public Service Commission face a 2026 deadline. The rules say the phased timeline would give operators time to assess risks, allocate resources and build technical capacity to comply with the new regulations.
New York will expand its community assistance teams under the new rules to offer technical guidance and regulatory support to local systems throughout the implementation process. The state will also launch a cybersecurity hub to centralize tools, training and grant resources for operators navigating the new requirements.
The Cybersecurity and Infrastructure Security Agency in 2024 released a joint incident response guide for the sector with the EPA and FBI urging owners and operators of water and wastewater systems to develop organizational-level incident response plans, establish strong cybersecurity baseline standards and enhance information-sharing measures (see: New Guidance Urges US Water Sector to Boost Cyber Resilience).
Stakeholders and the public can submit written comments by September 3, 2025 to the Department of Environmental Conservation.
