Sudden pressure drop detected — PL-047

Pressure fell from 6.28 bar to 2.31 bar in under 4 minutes at 03:47 UTC. Indicative of pipe burst or major valve closure upstream.

Minimum Night Flow exceeds threshold — FL-012

MNF of 64.8 L/s recorded against expected baseline of 42.0 L/s. Excess of 22.8 L/s (~82 m³/hr) indicates significant real losses in DMA Zone 4.

Pressure transient spike — PL-047

Pressure surged to 7.14 bar at 07:12 UTC, exceeding the 7.0 bar operational limit. Possible pump startup transient or valve slam. Monitor for fatigue.

Data gap — TL-003 offline for 47 minutes

Tank Level Logger TL-003 stopped transmitting between 01:22 and 02:09 UTC. Data gap of 47 records. Tank filling analysis for this period is unreliable.

Hydraulic efficiency below threshold — FL-012 to FL-019

Head loss between FL-012 and FL-019 is 2.4 bar over 1.8 km — 38% higher than Hazen-Williams prediction (C=120). Possible partial valve closure or heavy sedimentation.
