The Geyser Building, located in Parnell, Auckland, is New Zealand’s 1st 6 Green Star office building. When you see this building you realise the future has arrived! It is environmentally friendly on every front, including the trade waste drainage. UPG’s Stream HDPE Drainage system was installed for the trade waste drainage system in the Geyser project because it is the first choice for 5 & 6 Green Star buildings.
