Two towers which overlook the Nanjing Pukou District are scheduled to be completed by the end of 2018. Overflowing with 1,100 trees from 23 local species, as well as 2,500 cascading shrubs and plants, the installation will clean the city’s air by producing 132 pounds of oxygen every day. Additionally, passersby and tourists will be greeted with a breathtaking view. There will be approximately 600 tall trees and 500 medium-sized trees, in addition to the other foliage, that will help regenerate biodiversity in the area, c. 2017.

can anyone link me to projected water usage reports on these sorts of projects because as utopian as they look…. water is (often) a scarce resource too. depending on the location i guess
That's a really good question, that should definitely be considered. Whilst noting that these projects are undoubtedly irrigated, theoretically dependent on climate and plant choice, they should work like a plant covered cliff, or steep hillside, and not require water input. Further, there's strong evidence that trees 'call' rain, so a leafier city environment may well receive an increase in rainfall, helping to mitigate water usage.
