Key success factors for the action of Interagua at the service of the city and its inhabitants include:

• Consider the public-private partnership as a flexible framework made of commitments, trust and shared ability to adapt to unexpected changes.

• Promote the use of a mix of different technologies that would not have produced the same outcome if used independently (e.g. the combined use of macro meters, geographic information system and surveys allowed for reduction in water losses).

• Innovate at the service of local communities, covering both technical but also socioeconomic dimensions which are inherent to access to basic services.

• Promote bottom-up and participatory approaches, leverage social cohesion to reinforce appropriation processes and facilitate responsible behaviours by local communities.

• Work with pilot projects to assess feasibility and performance on the ground and then replicate and upscale best practices to make them available for the whole population.
