"The accepted reality is we must move towards sustainable cities, reduce per capita consumption of water as well as storm runoff, noise, the heat island effect and traffic," said chair Neal Landsberg.
"So water demand must be reduced through efficient use, collecting, managing, distributing and disposal including use of sustainable urban drainage (SUDS).
"We need to reduce, re-use and recycle rain water and grey water through design, installed technologies and appropriate use."
The Creating the ‘Green’ Urban Oasis event in London will ask if sustainable approaches can make commercial sense and what is the value of creating healthy places.
Speakers include landscape architect Luke Engleback. The "eco-urbanist" and expert on climate change adaptation will look at how landscape is the "green glue" that holds together developments.
An expert panel discussion will focus on how to turn buildings into "urban oases". It will look at flood and drought adaptation and water sensitive urban design, costs, planning and benefits.
