Waste water in processing facilities such as factories for food and beverage production, or even commercial kitchens, can often present unique requirements on the drainage systems.

In a membrane roof design, the overflow should have the same cross-sectional capacity as the primary outlet and give an early conspicuous warning to the building occupier that maintenance is required. But what about the weeping overflow, or one that activates prematurely?

When selecting passive fire and drainage systems, early engagement to select the right solution can have a profound effect.

With the recent unfortunate events in Wellington, it brings back into focus the elements involved in multi-storey buildings regarding fire safety, whether they are active or passive fire protection (PFP) systems within the building envelope. The building's systems need to work hand in hand and function appropriately in the event of a fire related emergency.

Consideration should be taken to futureproofing new developments to ensure surface water drainage is efficient and will prevent unnecessary flood damage to property. Our cities are becoming increasingly less permeable with a higher coverage of hard surfaces as they intensify.
