A temporary shutdown or reduced operation of a building and reductions in normal water use can create an environment favorable for growth of Legionella and other opportunistic bacteria. Building owners and managers should take actions to ensure that water systems are well maintained during and after a prolonged shutdown to minimize the risk of Legionnaires’ disease and other diseases associated with water among returning occupants.
