Ecological sink that separates gray water for reuse

This invention describes a domestic laundry room with two drains in the sculptor’s area, the first connected to the common drainage network and the second which offers a different destination from the first, allowing gray water to be captured (by closing the mouth of the first with a removable plug). Residual water generated during the processes of cleaning clothes, kitchen utensils, personal hygiene, washing food and similar processes, to be then conveyed to a reservoir for storage and reuse or further treatment .

Due to the increasing demand for drinking water due to increasing population and dwindling reserves of the vital fluid, the maximum utilization of this natural resource becomes an extremely important issue. That’s why, for years, governments around the world have urged people to take care of water by using it more wisely.

By analyzing the processes in which water is commonly used in homes, it has been found that most gray water, which is commonly discharged into the drainage network, has the qualities necessary to be used satisfactorily in multiple applications ranging from use in toilets, washing clothes (with detergent and only for rinsing), watering plants, cleaning floors and walls, cleaning vehicles, etc.

While those with significant amounts of fats, detergents or soaps, organic materials (food remains) and with turbidity, color, odor and transparency that are not to the taste of the user, reuse represent only a fraction of the total volume that is regularly consumed.

The industry has joined this initiative by redesigning a number of utensils that involve water from shower heads, washing machines and water-efficient toilets, toilet cisterns that reuse water from the sink , etc.

It should be noted that some laundromats were designed with a basin to store gray water, but they failed commercially as their size increased dramatically, discouraging buyers due to the increasingly limited space of modern houses, coupled with a considerable increase in price, in addition to the fact that they have a very limited capacity. However, of the whole house, the laundry room is the best gray water collection point, since it is here that the least polluted and the least dangerous to health is generated. Besides the fact that it is also the second point where they are most generated, the first is the shower or the shower, which has many disadvantages in various aspects for this purpose.

Traditional laundries have always had a single drain in the carver’s area, which is almost always connected to the drainage network, making any attempt to reuse gray water impossible, so it is wasted and must be treated again to return it. human consumption and later pumped to urban centers, all this involves high costs and great permanent losses of the vital liquid.

That is why, in order to solve this problem, this new sink has been designed with two drains in the sculptor’s area, one connected to the domestic drainage network and the other which offers a different destination from the first, allowing the collection of gray water that can be routed to a tank for storage or later reuse, allowing the user to determine at their discretion which destination will give the gray water by inserting a plug that closes the mouth of one drains depending on its purpose.


draining element.

A drainage element to allow traditional sinks to be able to separate gray water for reuse, the device costs around 4 euros.

Easy to install and requiring a minimum investment, we can condition any sink, sink, even the outlet of the washing machine to determine what end we want to give to gray water.

If we think the water is too dirty, we can eliminate it in the domestic drainage network.

And if it has the necessary characteristics to be reused by inserting a simple plug, it is diverted for storage.
