 In mid-2009 the finance chief of the Federal District, Mario Delgado, and the director general of the District's water company SACM announced that from mid-2010 onwards the District intends to enhance the participation of the private sector in water supply through concessions, under which the concessionnaires would buy bulk water and distribute it, thus providing an incentive to reduce non-revenue water.A total of four concession covering 11 of the District's 16 "delegaciones" would be bid out.The concessions would replace the existing four service contracts for metering and billing.
