Overview
- Police and fire services say groups have been forcibly opening hydrants across Paris suburbs and other towns to cool off, producing jets that can discharge 30,000–60,000 litres of water per hour and lower local network pressure.
- Officials warn the loss of pressure can compromise firefighters' ability to fight fires and that high‑pressure jets can injure people, cause electrocution if water reaches power lines, and provoke hydraulic shocks that may break pipes.
- Local responses have stepped up with arrests, deployment of police reinforcements including CRS after violent incidents, and municipalities using video surveillance to identify suspects.
- As a recent municipal action in Asnières shows, towns are seeking financial recoupment by billing parents for repairs and water loss, with two minors charged roughly €1,000 each for an incident that wasted about 80 cubic metres of water.
- Water companies and emergency bodies are rolling out technical measures such as hydrant security kits and sensor monitoring while reminding the public that illegal openings carry criminal penalties and heavy fines.
