Water Shortage Makes Housing Construction in the Var Conditional

Fayence – 15 July 2026: The renewed strain on the water situation in the Var department has once again brought an approach adopted in the Pays de Fayence since 2023 into focus: nine municipalities decided at the time to allow new housing projects only under strict conditions. The reason was concern that existing drinking water resources might no longer reliably cover additional demand.

The Prefect of the Var placed the entire department under a drought alert level effective 1 July 2026. While this does not yet entail comprehensive restrictions, authorities and municipalities are expected to monitor consumption and resource developments particularly closely. The Pays de Fayence intermunicipal community also points to investments aimed at safeguarding the drinking water supply, reducing network losses and adapting to recurring drought periods.

The nine member municipalities are Bagnols-en-Forêt, Callian, Fayence, Mons, Montauroux, Saint-Paul-en-Forêt, Seillans, Tanneron and Tourrettes. Their policy, agreed several years ago, was notable because it directly linked municipal development to the availability of essential infrastructure. In a region under heavy residential and tourism pressure, water thus becomes a binding criterion for spatial planning.

Of particular importance is the legal backing for this practice. The Conseil d’Etat confirmed on 1 December 2025 the rejection of a building application for a five-apartment building in Fayence. France’s highest administrative court found it permissible to reject an application due to a foreseeable threat to drinking water resources under Article R.111-2 of the Construction Code.

The case was based on specific findings: a 2021 study documented inadequate water supply in Fayence after two boreholes had run dry and a third was producing only small quantities. During the 2022 drought, households had to limit their consumption, and water was temporarily distributed by tanker truck. The court considered these circumstances a sufficient basis for the mayor’s decision.

The current situation in the Var is therefore more than a seasonal reminder to use water sparingly. It points to an institutional conflict between housing construction, municipal planning authority and supply security. The ruling from Fayence does not create an automatic construction freeze for other municipalities. However, it strengthens mayors’ ability to reject building projects when there is a demonstrably substantiated threat to the public drinking water supply.

For municipalities, this also entails a high burden of justification. Referring to general drought is not enough; robust data on the resource, the network and the expected additional consumption are required. In the Pays de Fayence, restrictions on construction are therefore linked to long-term measures to safeguard water supplies. The renewed drought warning shows that this balancing act remains relevant in the summer of 2026.
