Mike Rose, Director at RPS has put together the following guidance to outline the steps to be taken to help minimise the risk of legionella growth and the general deterioration of water quality, within engineered water systems.
01 Apr 2020
With many offices and buildings currently experiencing low or no occupancy levels, there are a number of steps that owners should be taking to minimise potential risks when buildings become reoccupied. The immediate implementation of these steps provides assurance that the water quality remains of a good standard and, in most cases, without the need for a disruptive chlorination of the water systems. ย
Where possible, and safe to do so, water systems in buildings should be kept operational and normal usage should be simulated. At present we wouldnโt advocate โmothballingโ buildings, which involves charging systems with chlorine and closing down access to the building. This should be seen as a last resort. Furthermore, at this time we also advise against draining water systems. This can cause leaks, biofilm growth and damage to pipes etc.
What to do next
Our guidance relates to water systems typically encountered. It doesnโt cover all scenarios and individual water systems which may have their own unique characteristics that need to be considered.
