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: €18.1M (its accounts).

What the intercommunality paid in 2025 for these kinds of purchase, from its accounts
- Insuranceall suppliers together · contract in the list: Les Assurances Territoriales Asterpaid €267k
The accounts say how much was paid for each kind of purchase, not to which company. A purchase paid by another public body (joint order, shared service) is not in them.
Why this total differs from the €18.1M 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
€13.1M of capital spending in 2025 (building, renovation, equipment), €184 per resident. Urban-area groupings of the same size: €101.
On top of that, €3.8M paid to other bodies for their own equipment (towns, intercommunalities, associations…).

Who is part of Communauté d'agglomération Bassin d'Arcachon Sud (COBAS)
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.
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.
