Urinate in the shower to save a wee bit of water

This is not my personal recommendation; the BBC is reporting this water saving approach.

University students are being urged to urinate in the shower in a bid to save water.

The Go with the Flow campaign is the brainchild of students Debs Torr and Chris Dobson, from the University of East Anglia (UEA) in Norwich.
They want the university's 15,000 students to take their first wee of the day while having their morning shower.
Mr Dobson, 20, said the idea could "save enough water to fill an Olympic-sized swimming pool 26 times".
The pair want those taking part to pledge their allegiance on Facebook and Twitter and have offered gift vouchers to the first people to join the challenge.
