Which risk increased for Roman aqueducts utilizing inverted siphons across deep valleys?

💡 Explanation

When Roman aqueducts used inverted siphons, hydrostatic pressure increased significantly at the bottom due to the water column's weight, risking structural failure of the pipes. Therefore, structural failure was a major risk, rather than sediment, freezing or algae, which affected other parts or used other mechanisms.
