Trees and Integrating Stormwater

How can you utilise rainwater to enhance your tree growth?

Our cities are designed in a way that when it rains, the  water is directed away into catchment basins and  pipes, which leaves street trees without rain water

At Citygreen we have designed a paved tree pit  structure that allows the trees root system access  rainfall. This design present an opportunity to restore predevelopment flows and improve water quality  within our cities.  The design enables, rainfall that falls on the pavement to be directed permeable pavements into the tree pit  and then become accessible to the root system.

This supports the continued health and growth of the tree  to cool down the neighborhood and promote evapotranspiration. The interconnected design recreates natural  environmental cycles, and facilitates rainwater harvesting.

It is important to understand the difference between ‘passive irrigation’, ‘water balance’, and ‘stormwater harvesting’. Passive irrigation is the practise of intercepting some water, and directing to the tree for expected benefit of  the tree. This is a good practise, but leaves many of the benefits untapped.

“Our experience, in working with a Citygreen Design Studio was second to none. We found responses from the design studio to be very timely, and technically thorough. We went backwards and forwards a number of times, looking at different iterations of the design and, nothing was too much trouble to examine and explore different possibilities. I would highly recommend the Citygreen Design Studio to any future client considering using your services.”
