The basin committees are deliberative bodies in charge of the administrative management where negotiations and participatory decision making take place to debate on water issues, arbitrate use conflicts and design basin management plans. The basin agencies are the “executive arms” of the committees, providing technical support and implementing their decisions. The latter are financed through the collection of bulk water fees with the objectives to i) better balance water demand and supply, and ii) provide the necessary funds for the adequate operation and maintenance of existing systems and new projects at the basin scale.
