This week on The Sydneyist we’ll welcome 2024 with talk of SPONGE CITY. Elizabeth Farrelly speaks with one of the world’s most imaginative engineers, Tristram Carfrae, global lead of ARUP Engineers, about how to keep rainwater where it falls, rather than sluicing it out to sea - and why Sydney ranks so badly in this regard. Join us on for a great conversation on The Sydneyist, Eastside Radio 89.7FM or streaming on EastsideFM.org every Thursday evening at 6pm.
