Water Safety Management

Microorganisms such as Legionella species and Pseudomonas aeruginosa can grow in water distribution systems. Growth is promoted by conditions such as low flow, stagnant water, and warm water temperatures.

This document is concerned with the management of risks posed by water systems to ensure sources of risk are identified, and measures taken to prevent and control risk when water systems become contaminated with Pseudomonas aeruginosa from water outlets, or Legionella species, or other water associated micro-organisms; and where there is a means of creating and transmitting water droplets or aerosols that could be inhaled.
