The approval of the Water Law in Brazil (Law nº 9.433/97) did not guarantee its operation, including the partaking management principle on the jurisdictions of basin organisms (comitês de bacias hidrográficas). This work approaches the importance of conjunct consideration of scientific and experimental knowledge, as well as the formation of a net information society, for the viability of the process. Aspects such as deciders training, systemic vision, subjectivity, values, perceptions, attitudes, ethics and dialog are some of the approached cognitive elements, which are considered strategic for the success of partaking management. The work aims to raise reflections about the role of knowledge and about the relevance of the integration of individual qualities on the search for efficient deciding processes. The research was made as part of the doctorate process at the Centro de Desenvolvimento Sustentável/UnB.
