Control Schemes

The written scheme is separate to the Legionella risk assessment and is a legal requirement identified by the Health & Safety Executive in their ACoP L8 (Fourth edition) Legionnaires’ disease. The control of legionella bacteria in water systems.

A Control Scheme for Legionella is a comprehensive Legionella risk management document that clearly identifies those measures required to control the risks from exposure to Legionella bacteria, and how those measures are implemented and managed so that control over water systems is achieved and remains effective.

The written Control Scheme forms an essential risk management document that should be developed as a practical tool to be used by all parties involved in the Legionella control process.

Our Waterman Consultants can create site-specific Control Schemes for all types of water systems & services to help you comply with ACoP L8 (Fourth edition).
