Clayton County Water Authority

Profile narrative

The Clayton County Water Authority is a public utility responsible for the treatment and distribution of drinking water. It operates a network of pumps, valves and storage facilities that maintain system pressure throughout its service area. The authority monitors water quality to ensure compliance with state and federal health standards. Its infrastructure supports residential, commercial and industrial consumers in the Clayton County region. Routine maintenance and operational oversight are conducted to keep the water supply reliable and safe.

The utility serves approximately 300,000 customers located in the Atlanta metropolitan area. This customer base represents a significant portion of the water demand for Clayton County and surrounding communities. The service area includes both urban neighborhoods and suburban developments that rely on the authority for potable water. By providing a continuous supply of water, the authority supports public health, fire protection and economic activity in the region. Its operational footprint is defined by the geographic boundaries of Clayton County and the interconnected water mains that extend into adjacent jurisdictions.

In July 2026 the authority experienced a cyber incident that disrupted water pressure controls and triggered a boil water advisory. The event involved unauthorized remote access to pumps and valves, prompting a temporary shift to manual operation while service was restored. Federal agencies issued warnings about similar intrusions across multiple states and advised utilities to strengthen passwords and consider disconnecting online controls. Although investigators noted similarities with Iran‑linked activity, no formal attribution has been made for the Clayton County breach. The incident highlighted the authority’s role in regional water security and its need to balance operational technology with cybersecurity defenses.
