Challenges

-To keep a strategy of cooperation among the public organizations

To establish legislation and mechanisms that mitigate the differences between the formal and the informal city

- To expand the infrastructure and control of environmentally negative uses

- To optimize productivity of the sewerage

- To develop studies for improving the water treatment plants and for innovative interventions in the raw water (pre-treatment in the

reservoir and tributaries)
