it can take 2,700 litres of water to produce a single conventional t-shirt

Estimates vary based on where the cotton is grown and how it's produced, but the widely accepted global average is that it takes about 2,700 litres of water to produce a conventional cotton t-shirt*. Growing cotton takes about 60% to 70% of the water used. Once harvested, the cotton must be bleached, spun and dyed - processes which are also incredibly water-intensive.
