 So what does a water-wise world mean for a city? Well, the city has water systems. Water systems that deliver drinking water, sanitation, that ensure that wastewater is collected and treated properly and efficiently. Water systems also ensure that rainwater and stormwater is drained safely out of the city. For these water systems to be more efficient, we need to plan them in the context of the whole city, in the way we design our buildings, our neighborhoods, and even the way we integrate it all at the basin scale. Looking at what's happening upstream and downstream of the city, at what the other stakeholders in the basin are doing, will lead us to a secure city from drought and floods risks. This is about all of us in the city working together, from the leaders to the institution managers, the professionals, the citizens, all working together towards the same vision. Now what's important is to have strong leadership. Water professionals work hand-in-hand with urban planners, leaders who can inspire all of us to work together towards that water-wise city that we can deliver.
