← HistoryWhich outcome occurs when a Roman aqueduct's settling tank is bypassed during heavy rainfall?
A)Increased sediment load in water supply✓
B)Reduced flow rate due to debris blockage
C)Structural damage from hydrostatic pressure
D)Contamination by overflowing sewage systems
💡 Explanation
When the settling tank is bypassed, increased sediment load occurs because the water is no longer pre-filtered, meaning fine particles are not removed from the water. Therefore, sediment increases, rather than reduced flow, structural damage, or sewage contamination, which involve blockages, pressure, or sewer overflows, respectively.
