Cybersecurity Risk Management, Strategy, and Governance [Line Items] |
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | We have taken critical steps to ensure the security and protection of our computer systems and networks. Our processes for assessment, identification and management of material risks from cybersecurity threats include routine monitoring of vulnerabilities, evaluations of new service providers, written policies for incident identification and management, and regular testing and assessment of our cybersecurity posture. We have integrated cybersecurity risk management as part of our company-wide culture. The measures undertaken include, but are not limited to, monthly cybersecurity training for all employees and frequent communication to all employees on the importance of cybersecurity measures. We continue to advance our cybersecurity governance program and are evolving key practices to align with the National Institute of Standards and Technology (“NIST”) Cybersecurity Framework. These efforts include strengthening our risk assessment processes, control environment, and incident‑response capabilities. We have engaged third-party experts to assist us in monitoring and managing our cybersecurity process. Furthermore, we monitor cybersecurity threats at certain of our third-party vendors on a regular basis. As of the date of this report, we are not aware of any material risks from cybersecurity threats that have materially affected or are reasonably likely to materially affect the company, including our business strategy, results of operations, or financial condition. We have discussed cybersecurity risks that may affect the company in Item 1A, “Risk Factors,” under the headings, “The necessity for ongoing physical and technological security has resulted, and may continue to result, in increased operating costs,” “Water Utility Services rely on information technology and systems that are key to business operations. A system malfunction, security breach, cyber-attacks or other disruption that compromises our information and expose us to liability and adversely affect business operations. In addition, noncompliance could expose us to liability and adversely affect business operations,” and “We may not be able to maintain adequate insurance coverage at reasonable costs, or at all, to cover all losses incurred in our operations.”
