Preventing Legionella and stagnation in water services – awareness of problems, especially in a post Covid world.

November 19 @ 1:30 pm - 2:30 pm

Speaker: Niall Phillips, Hygiene and Technical Services Manager, Hydraclean

About the session

This session aims to highlight potential problems with water stagnation, biofilm formation and Legionella proliferation in water systems and to show how these issues have been exacerbated by reduced footfall and occupancy in buildings due to lockdown followed by an increase in home working.

The session will also look at solutions to these issues and ways of balancing the need for safe water systems with the environmental and cost impacts of control regimes.

About Niall
