Texarkana Water Utility

Texarkana Water Utility (TWU) operates as a critical water supply provider headquartered in the United States, delivering essential water services to communities within Bowie and Miller Counties. Its operational footprint is explicitly defined by these two counties, where it functions as a core utility supporting residential, commercial, and public sector needs. The utility's infrastructure and network are integral to the region's daily functioning, serving not only direct customers but also underpinning the operations of other local government entities. This interconnected role was starkly revealed during a significant cybersecurity incident, underscoring TWU's position as a foundational component of the area's public services and its reliance on secure network operations to maintain service continuity across multiple jurisdictions.

The most documented event in TWU's recent history is a ransomware attack discovered in late November 2020. This incident involved prior network compromise and triggered widespread system outages that extended beyond the utility itself, disrupting courthouse operations and affecting various BiState agencies that depend on the same network environment. Despite the severity of the attack, which necessitated extensive PC and system repairs and prompted deliberate shutdowns, TWU successfully maintained uninterrupted water treatment and delivery services. This demonstrated a critical competency in isolating operational technology from the compromised business network, a vital capability for any water utility. The full technical and data breach scope remained under investigation for some time, with initial assessments finding no evidence of personal data exfiltration. The recovery process was prolonged, highlighting the complex, multi-jurisdictional challenge of restoring IT systems for an organization whose digital health is so closely tied to regional government functionality. The incident serves as a key reference point for understanding the utility's exposure to sophisticated cyber threats and its operational resilience protocols under duress.
