100 contracts signed in 2025 · €87.4M before tax

Why this total differs from the €68M paid to companies

These are the amounts of the contracts signed in the year, over their whole length, not what was paid. The money paid in a year also goes to older contracts and to purchases too small to be published (under €40,000 excl. VAT). For a framework agreement, the amount is a ceiling.

Investment and works

€33.6M of capital spending in 2025 (building, renovation, equipment), €104 per resident. Urban-area groupings of the same size: €114.

Largest works contracted since 2023, among published contracts. Amounts planned at signature, often spread over several years.

On top of that, €12.4M paid to other bodies for their own equipment (towns, intercommunalities, associations…).

Understanding these figures

Who does what

The intercommunality collects and treats waste, often runs water and sanitation, organises urban transport, and pays part of its revenue back to its member towns.

Official table of responsibilities (July 2025)

Why the levels are not added up

The same euro can appear twice: once when a region or a département pays a grant, again when the town spends it. Each page shows its own body’s spending.

Where these figures come from

Spending: the accounts of the main budget published by the DGFiP, by public policy. Revenue, debt and taxes: OFGL. Contracts: published contract data (DECP), amounts planned at signing.
