shower saves 90% water

A typical 10-minute shower can use 150 liters of water and requires energy to keep all of that incoming water hot. An innovative new design recycles shower water so only around five liters of water is needed and can be used and reused for weeks.

The OrbSys shower system is the brainchild of Mehrdad Mahdjoubi, an industrial designer. The idea was first conceived when he was studying at the University of Lund in Sweden when he wanted to combat the large amounts of water waste associated with bathing.


After graduation, he began to collaborate with NASA to bring life to the idea. Astronauts recycle water all the time, as urine, bathing water, and even condensed humidity from the crew’s breath are filtered into drinking water. That urine and breath aren’t just collected from humans, even the lab rats are included in this massive recycling effort. Mahdjoubi was inspired by efficiency onboard the ISS and has been working tirelessly to recreate a system like that on Earth.

Simple, but brilliant

It may sound a bit disgusting to have old water circling through the pipes and falling back on your face, but a state of the art filtration system means that the water coming out of the shower head is clean enough to drink and is actually more pure than average tap water.

As the water falls down, it goes down into the drain, through the filtration system, and then is pumped back up to be used again. Because only a little heat is lost during this process, it only needs to be slightly reheated, which can significantly reduce energy costs.

Orbital Systems has done the math, and over the course of a year, this showering system can save over US$1300 on energy bills.


To test the practicality of the shower, 1000 people used the showers over the summer and gave feedback.

  • The system produces 24 liters per minute, which may entice more customers who have passed on previous low-flow design
  • The efficiency of the filtration system has the potential to be used on many other applications where water waste or water cleanliness is an issue
  • When the filters become dirty, they can be sent back to the company to be recycled, which also minimizes landfill waste from filters

For house owners and businesses

This new shower system isn’t just saving house owners. Think of big swimming pools, sport centers, sauna’s and even business who offer bathroom facilities to their employers. For example: Ribersborgs open-air bath in Sweden saved $51,000 a year (5,475,000 liters of water and 180,000 kWh) with this shower system.
