What is the minimum requirement for external tank fill intakes on a Mobile Water Supply (MWS) apparatus?

The minimum requirement for external tank fill intakes on a Mobile Water Supply (MWS) apparatus is that there must be at least two external tank fill intakes. This design promotes efficiency and reliability during water supply operations. Having two fill intakes allows for faster filling of the tank, which is crucial in emergency situations where time is critical. It also provides a backup option in case one fill intake becomes unusable due to malfunction or contamination.

This requirement is important for ensuring that the MWS can quickly replenish its water supply, maintain its operational capabilities, and effectively support firefighting efforts. Multiple fill intakes enhance the flexibility of the apparatus, allowing it to draw water from different sources simultaneously or provide redundancy in case of difficulties with one intake. Thus, the specification for at least two external tank fill intakes is a fundamental aspect of MWS design that enhances operational readiness.
