Within the frame of the Oudin-Santini Bill, the Joint Syndicate of Production of the Rennes Region supports the communities of Dankassari in the field of access to water.

Within the framework of the Oudin-Santini bill, The Rennes Water Production Syndicate has been supporting the Rennes Area Decentralised Cooperation actions concerning access to water.

It has now become the Rennes Area Water Community, with wider authority over the whole cycle of water in the Rennes Metropole communes.

In Dankassari the support is used to rehabilitate water drill holes.
