GRIS water saving system: A simple tool to capture and recycle all the water you use during a shower

GRIS is a set of water-containers that are to be laid on the bathroom floor under the shower. They then capture water from the showerhead, a person’s body and from the wall whilst a shower is being taken. The collected water can be stored in these containers for a while and/or immediately be reused for other purposes including toilet-flushing, cleaning, washing or watering the garden, for example. GRIS can collect up to 95% of the shower water.

One set of containers consists of four 33x33x10cm size interlocking water containers with a non-slip surface. Each container has a water collector opening and a spout opening with open-close threaded caps. The water can be reused by simply lifting one of the containers, opening the cap and pouring out the grey-water.

Each container capacity is 10 liters, which means 40 liters per set. The four transparent containers allow users to see the amount of water filled. Gris is able to hold a 150kg person and is made of PET-R plastic – a highly reusable plastic material with a heat resistance up to 70 celsius degree. The product can be cleaned easily with baking soda, vinegar or conventional washing soap as well. The estimated lifetime of a GRIS product will be 5 years.

South America is facing a large-scale water crisis caused by factors such as climate change and deforestation. Water conservation is essential, yet household water recycling systems are expensive and complex. The product can help combat this problem. Currently, water scarcity affects over 40% of people in the world, a proportion set to reach two-thirds by 2050. In addition, a mere 2.8% of the water is fresh and only 0.01% is in lakes and rivers.

Gris does not only recycle water but can contribute to changing water usage. For example, an average citizen of Sao Paulo uses 175 liter water per day although the World Health Organization recommends using 110 liters. The Gris containers can cover 40 liters (60%) of the 65-liter difference.

With a population of 2.8 billion people affected by drought and water scarcity, according to UN statistics, the company estimates that 20% of households are potential customers in the long term. In addition, it foresees that at least 50 million of environmentally-conscious potential customer in the developed countries as well, will be willing to use Gris to save water.

In a 4-member family the saving could amount to 5,000 liters per month. Calculated on the water fee in Brazil, this is a 15 USD saving every month. In a period of 4 months, Gris will amortize its own cost and within 3 years a family could save 540 USD.
In total, the market size estimated is about 250 million households in the world at a cost of 37 USD per unit with production costs at 22 USD per unit.
