The UK average is, drum roll pls... 140L per day (!!)
This per capita consumption (PCC) has been a fascinating thread through this week's #WaterwiseConference. PCC used to be low & went up in the 1990s as ppl showered more & installed en-suites (The Men's Health effect?) [2/9]

The water industry is falling over themselves to bring PCC down, having remained stubbornly high. The tech exists for low water homes but remains expensive. Here's @ArtesiaRob outlining a few of them (intrigued by an air flush toilet!):

The industry already knows the best way of bringing PCC down: water meters. When @SouthernWater increased its metering from 41% of customers to 91%, its PCC became the lowest in the UK (127L) + leaks detected early & reduced. It's now aiming for 100L PPC. https://www.southernwater.co.uk/water-for-life/target-100
#COVID19 has made this challenge far harder. Stuck at home we use water that we would have otherwise flushed at work or eaten in Pret. These @thameswater figures show household water use in #lockdownuk up by a staggering 10-60%, and PCC up to 155L... [5/9]

Households used more water in May than even during the record-breaking summer of 2018. [6/9]

However, there's a twist to this PCC tale (or tail).
The 140L average is greatly skewed by a very long tail of very high users. The Mode use is *already* 100L (Southern's 2040 target) and many use below 50L (Cape Town 'Day Zero' levels). [7/9]

And the previous 3 slides from @thameswater's Andrew Tucker are only possible due to smart meters: an industry game changer that give real time data, but expensive to roll-out. Users with smart meters see usage go down 12-16%. And smart meter data suggest the Covid-increase in...
...PCC was offset by low business demand: during lockdown, total volume of water supply in London went down. Analysts will be poring over this for years. But it suggests that PCC may not be the best metric to focus on, afterall. [9/9]
