The contribution of the associated communes mentioned in 1° of article L. 5212-19 is compulsory for these communes for the duration of the syndicate and within the limit of the requirements of the service as determined by the decisions of the syndicate.
The committee of the syndicate may decide to replace all or part of this contribution with the proceeds of the council tax on second homes and other furnished premises not used as the principal dwelling, property taxes and the business property tax.
The levying of these taxes may not, however, be continued unless the municipal council, which must be consulted within forty days, has not objected by allocating other resources to the payment of its share.
