The Prefect, the French federal representative in St Martin, just put out an update. Since most here don’t seem to speak/read French I ran it through Google Translate:

WATER SUPPLY DISRUPTIONS: SITUATION UPDATE at 10:30 AM.
A crisis meeting was held this morning at the prefecture to take stock of the water supply situation in Saint-Martin following the ongoing social movement at SAUR.
The gradual re-supply of Marigot is underway, and at this stage, half of the production is operational.
The prefect has asked SAUR to accelerate the acquisition of the missing parts needed to return to full production capacity as soon as possible.
The prefect strongly condemns hostile and dangerous courses of action that have led to the theft of parts vital to the operation of the plant, thus endangering the health and public safety of Saint-Martin and the people of Saint-Martin.
Pending a full recovery, a prefectural decree has been issued to limit non-essential uses of water. In addition, a water supply ramp is made available to users in Galisbay to meet urgent needs.
A press briefing will be held today at 3 p.m. to inform the population of the development of the situation.
