The correct answer is focused on the role of domestic water systems in supplying water for standard daily usage. Domestic water systems are designed primarily to meet the everyday needs of occupants within a healthcare facility, including drinking, cooking, bathing, and sanitation.

These systems are engineered to provide a consistent and safe supply of water that is essential for the daily operations of a healthcare facility, where hygiene and patient care are paramount. The management of these systems ensures that water quality is maintained, which is vital for both patient safety and compliance with public health regulations.

In contrast, while fire suppression is a key component of facility safety, it does not fall under the primary role of domestic water systems. Fire suppression systems typically utilize dedicated plumbing lines designed specifically for emergency scenarios. Similarly, water used for construction projects or emergency purposes are distinct functions that do not define the core purpose of domestic water systems, which primarily cater to routine facility demands.
