A hospital must have two water supply systems as a backup to ensure that it can maintain a continuous and safe water supply for critical operations. This redundancy is essential because hospitals require a reliable water supply for various functions, including patient care, sanitation, and emergency services. Should one system fail or become disrupted, the second system can immediately take over, minimizing potential risks to patient health and safety.

Furthermore, having two water supply systems is part of the regulatory and operational standards aimed at enhancing the overall resilience of the facility. This backup system design not only confirms the compliance with health and safety regulations but also ensures that essential services can continue unhindered, particularly in emergencies or during maintenance of the primary supply. This practice reflects the highest standards of hospital readiness and patient safety.
