Description
In April 2023, four villages (~3,000 residents) in Pyrénées-Orientales were placed under a tap water drinking ban when their shared well fell to 30 cm above the pump intake. Emergency response was improvised: free bottled water (one 6-pack of 1.5 L per person per week) and testing of a farmers' backup well as an alternative source. Neither restored a drinkable network. The durable fix required interconnection works to neighbouring networks, undertaken only after the crisis hit. The episode was not isolated: in summer 2022, more than 100 communes nationally had water trucked in and over 1,000 took exceptional measures; 76 communes around Perpignan remained in official crisis status in April 2025.

Lessons learned
- A single shared well is a single point of failure: once it physically runs low, no demand-side measure restores supply — interconnection to a neighbouring network is the only durable fix.
- Emergency bottled water distribution is far more expensive per resident than pre-crisis interconnection and leak repair — making the cost case for preventive works straightforward.
- Backup sources (e.g. agricultural wells) must be surveyed, water-quality tested, and administratively permitted before a crisis; identifying them mid-emergency adds weeks of delay.
- Regional droughts persist across multiple years: 76 communes around Perpignan were still in crisis two years after the 2022–2023 episode, so a single wet winter does not close the resilience gap and structural works cannot be deferred.
