Measures to combat COVID-19 have resulted in many buildings – such as restaurants, offices, factories and hotels – being unoccupied for extended periods of time. Extended building vacancies have the potential to impact drinking water quality within the premises due to non-use.
When water service is returned or when use is restarted in a building after an extended period of non-use, it is important to address the stagnant water in the building’s plumbing to ensure safe drinking water quality is provided.
The CDC has published Guidance for Building Water Systems to help minimize the risk of diseases associated with water that has likely become stagnant in buildings. The guidance recommends an eight-step process before reopening a building, which includes flushing the water system and maintaining the water system.
