How to save water: taps, nozzles, aerators and other devices

How to save water: taps, nozzles, aerators and other devices

Despite the different design solutions of “economical plumbing”, in principle there are only two ways to save water: the recycling of gray drains and reducing consumption without compromising the efficiency of using a plumbing fixture.


The first principle has long been known in Europe, where waste separation is a widespread practice. Yes, and we have “private traders” with autonomous sewerage sometimes use this scheme, and let the treated gray drains to water the site.

But how can this be done in a city apartment? The answer was found a long time ago – to combine the washbasin and the toilet bowl. Even in a “compact” that is conventional in design, such a solution looks quite natural.

There are also more “solid” sets made of stainless steel, in which the classic toilet bowl is combined with a cabinet for the sink and drain tank.

The only inconvenience of such “frontal” models is that in order to use the sink, you need to have free space on the side. But there are also asymmetric models. For example, in such a set, the toilet bowl is “shifted” to the edge of the cabinet. In this case, the toilet was “turned” by 45°.

And one more example of the perpendicular arrangement of the axial lines of the toilet bowl and sink. The tank consists of two compartments: the right one for clean water, the left one for waste water. And in order to know when the left tank can be used, an indication is provided in its key.

Economic mixers

You can argue for a long time which mixer is more economical – two-valve or single-lever. For example, the British believe that a two-valve design prevents hot water from being wasted, which is more expensive than cold water.

But if we talk about the overall water savings when turning on / off the mixer, then the best are sensory models that are triggered when hands (or other objects) approach at a distance less than the sensor sensitivity threshold. Moreover, this threshold can be adjusted. And the operation of the sensor and the shut-off valve is provided by a battery.

The simplest model of such a mixer may have a single temperature control knob.

Advanced models are equipped with a built-in thermostat, in which the temperature is regulated by turning the knob. In the initial position, the thermostat is set to a comfortable temperature of 38°C.

And mixers are considered to be the height of perfection, the operating modes of which are configured using the touch control panel.


In this chapter, we will briefly talk about nozzles that save water.

The most sophisticated nozzle has a sensor like a sensor faucet. And the simplest are aerators. The vast majority of mixers go on sale complete with them. It can be a head with a metal mesh or a plastic grill.

There are models of aerators with a variable direction of the jet and switching modes of operation, and for kitchen faucets they use nozzles with an aerator on a flexible hose.

The task of the aerator is to obtain a volumetric stream of water with a small pressure. And this is possible if it is divided into streams (like a shower head) or saturated with air
