ホルヘ・ラファエル・ビデラ
In 1980 the military government under Jorge Rafael Videla decentralized the provision of water and sanitation services in the main cities served by OSN, except for the metropolitan area of Buenos Aires where OSN continued to provide services. In other cities OSN transferred its responsibilities to provincial governments. Each province chose its model of service provision (municipal, public enterprises, cooperatives or others).
