The UK’s highest residential skyscraper - One St. George Wharf will fast become an architectural landmark across the London skyline. When built it will rise 181 meters over the St. George Wharf development with a total of 49 floors. ‘The Tower’ will bring to London a new standard in design for living. Taking a not only a green approach to construction but delivering a continued contribution to the environment long term throughout the buildings services, pioneering sustainable development and technologies. 


A fundamental feature of the tower is its approach to green issues including the efficient use of natural resources and protecting the natural environment. The commitment of St. George to sustainable development and an innovative approach lead them to Project Fire who provided the perfect sustainable solution for the fire protection strategy at One St. George Wharf... Zonecheck. Traditionally routine testing of sprinkler systems is incredibly wasteful, discharging clean drinking water to drain. As a result large fire pumps are run in order to refill the system and not to mention the cost and man power required to carryout such tests. 



“An annual saving of 281,600 litres of drinking.”



Zonecheck is a sustainable flow-switch tester which saves 1280 litres per flow-switch per annum. ‘The Tower’ requires 220 Zonecheck, this is an annual saving of 281,600 litres of drinking water a year! 


Zonecheck was specified for the development although an obstacle had to be overcome. The design of the building left little room between floors and Zonecheck would not fit as planned. Being the only product of it’s kind an alternative is not available on the market and so Project Fire went back to the drawing board in order to find a solution. Zonecheck was finally redesigned for the project so that The Tower could add Zonecheck to its long list of pioneering green and sustainable technologies. Zonecheck saves huge amounts of drinking water and energy, making efficient use of natural resources whereas traditional methods are increasingly costly to both the environment and the building owner. Over the life cycle of the building it is predicted that without Zonecheck the total amount of water wasted during testing would amount to approximately 16.9 million liters of drinking water.
