Showerloop

Minimising water and energy usage through real-time shower ‘looping’

T

ypical ‘linear’ shower systems are

wasteful; taking clean water heated

to a comfortable temperature, the

resulting grey water and heat energy

goes down the drain after a

moment’s use. The longer the shower,

the bigger the associated energy and water footprint

becomes. Jason Selvarajan, an environmental

engineer from Finland, started the Showerloop project

in an attempt to create a water and energy-saving

shower solution to reduce this footprint, while

bringing water and basic sanitation to people and

places that otherwise wouldn’t be able to access it.

Jason’s primary objective during POC21 was to

improve the appearance of his system and to

introduce his work to a broader audience.

THE MAN WHO LOVES TO SHOWER...

A standard shower uses approximately 10 litres of

water per minute and a substantial amount of energy

to heat the water, depending on the temperature.

Showerloop’s filtration system cleans shower water in

real-time, reducing the amount of water and energy

consumed by up to ten times. According to Jason,
