EcoWater- Nimbus: Digital Legionella Control Validation 

The EcoWater Nimbus Platform is a specialized, IoT-enabled Digital Water Management System (DWMS) designed to provide Water Treatment and Water Hygiene companies with a high-integrity, verifiable infrastructure for proactive Legionella risk control and regulatory compliance.

Recognizing that the core of Legionella management lies in controlling proliferation conditions, the Nimbus Platform offers crucial support by validating the execution of preventative hygiene measures.

Core Technical Functionality and Risk Mitigation:

• Flushing Regimen Validation: The platform delivers reliable, time-stamped verification that both manual and automated hygiene flushing schedules for infrequently used outlets and water lines have been executed to the specified flow duration and frequency. This feature directly substantiates the control measure related to preventing water stagnation (water age), which is a key requirement of the ACoP L8, HSG274, and HPSC National Guidelines.

• Time-Series Temperature Profiling: Nimbus utilizes IoT sensor telemetry to continuously monitor and record time-stamped temperature profiles at critical control points (e.g., calorifier flow/return, cold water storage vessels, and representative distal outlets). This function provides real-time assurance that water systems are maintained outside the Legionella proliferation temperature range (20C to 45C).

• Intelligent Deviation Alerting: The system incorporates a robust alerts and alarms matrix, instantly flagging non-conformance when monitored parameters breach defined Critical Control Limits (CCLs). This proactive notification system (e.g., for temperature drops or missed flushing tasks) enables the service provider and Duty Holder to initiate rapid corrective action and minimize the window of amplified risk.

• Electronic Audit Trail (e-Logbook): By centralizing all collected sensor data, validated task execution records, and incident response logs, the Nimbus Platform establishes a secure, non-repudiable electronic logbook. This secure repository provides the comprehensive evidence required to demonstrate due diligence and streamline regulatory compliance audits.

The Nimbus Platform empowers providers to transition from reactive compliance documentation to a proactive, data-driven methodology for managing the conditions that favor Legionella growth.
