Where the money goes
The €4.1M spent in 2025, by who receives it.

Contracts state a maximum amount for their whole term, often several years. That amount differs from what was paid. Purchases, services and works paid to companies by the intercommunality in 2025: €2M (its accounts).
- Butin - Sedic1 contract over 4 years · at most ~€55k a year on average · framework agreement: maximum envelopeup to €220k
- Espace Architecture International1 contract over 6 monthsup to €61k
2 contracts signed in 2025 · €281k before tax
Why this total differs from the €2M of purchases, services and works 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
€1.1M of capital spending in 2025 (building, renovation, equipment), €28 per resident. Town groupings of the same size: €90.
On top of that, €133k paid to other bodies for their own equipment (towns, intercommunalities, associations…).

Why the levels are not added up
