New research suggests that the 30-year-old data water companies use to predict extreme rainfall may be underestimating by 40% the pressure drainage systems are under, with the figure rising to 60% by 2080 as climate change kicks in, according to the report "New climate data challenge sewer design," sponsored by the UK Water Industry Research.
