What is essential for the operation of an establishment regarding water supply?

The requirement for a water supply in an establishment is that it must come from an approved source. This means that the water supply has been vetted and meets all the health and safety standards set by regulatory bodies. Utilizing water from an approved source ensures that it is safe for consumption and use in food preparation, sanitation, and personal hygiene, which are essential for maintaining public health and preventing the spread of waterborne illnesses.

In contrast, relying on a river source or private well water may not necessarily meet the required safety standards unless specifically tested and approved. Distilled water, while safe for consumption, is not typically feasible or practical for the daily operational needs of an establishment, making it impractical as a standard requirement. Being sourced from an approved facility ensures compliance with local regulations and reinforces the safety and integrity of the establishment's operations.
