We have designed a product that helps students wash their laundry using less water than a normal washing machine. Water is collected in the removable water tank, which can be placed on the shower floor like a mat. Once you have finished showering, you can reattach the tank to the base. The machine filters the water and uses it to wash your clothes. If every student in London were to use our washing machine, we would save enough water to fill 700 Olympic size swimming pools per year.
