Act now.

EMERGENCY WATER SAFETY RESPONSE 

A positive Legionella test is not the end.
How you respond in the next 48 hours determines the outcome.

When Legionella is confirmed in a healthcare, hospitality, elderly care, or public facility, rapid corrective action becomes critical. Public health authorities and facility operators are expected to document the measures implemented to reduce exposure risk and maintain safe water access during remediation activities.

​

Installed point-of-use filtration can provide an immediate physical barrier at the outlet level while broader system remediation and investigative procedures are ongoing. MWT supports facilities with rapid-response deployment, technical documentation, and operational guidance designed to help maintain continuity during active water safety incidents.
