The green technology even extends to the toilets. The men's toilets use waterless urinals, and a rainwater run-off system collects water from the roof and stores it underground. Club Watt aims to collect 550,000 litres a year, which it then spectacularly flushes through transparent pipes to the club's toilets every time a clubber flushes.
