Today, the majority of plumbing fixtures are from European manufacturers (Grohe, Hansa, Hansgrohe, Ideal Standard, Damixa, Roca, Laufen, Oras, Jacob Delafon, Geberit, Gustavsberg, WasserKRAFT, Mora Armatur, Villeroy & Boch, Keramag, VitrA, Kludi, Plados, etc. ) are “tailored” so that consumers can save water and not experience discomfort. For this purpose, water-saving technologies are being introduced into faucets, shower heads, and toilets. Let's talk about this.

The least economical are two-valve models, in which it takes longer to “adjust” the flow to the desired temperature and intensity. The design of a single-lever mixer allows you to set the temperature and water flow with a slight movement (provided that the lever moves smoothly, without jerking), as well as change the flow intensity without changing the temperature. Manufacturers have included several ways to save water in single-lever models, including hot water, which, as you know, is more expensive.
In traditional faucets, the water flow rate is approximately 12 l/min, while in faucets with the Eco function it is reduced by almost 60%, to 5 l/min.

Almost everyone is equipped with an aerator - a device built into the tip of the spout. Mixing it into the air stream at the outlet provides at least 10–15% water savings. At the same time, the restriction of the flow is imperceptible; on the contrary, the stream becomes voluminous, foamy, and more pleasant to the touch.

There are several ways to limit the flow limit. For example, using an elastic ring or membrane built into the aerator. This reduces water consumption by 60%, that is, up to 5 l/min. Another method is two-stage adjustment of the control lever. Its slight resistance will serve as a signal about the transition from economy mode to maximum flow mode. Manufacturers call this technology differently (Eco-Save - Damixa, Eco-Plus - Kludi, “green” eco-button - Oras, Eco-Disk - Roca), but its goal is the same - 50–60% water savings, that is 5– 7.5 l/min versus 12–13 l/min.

If saving hot water is important to you, if you want to protect your loved ones (especially small children and the elderly) from burns, ask when choosing a mixer whether the model you like has such protection. Its essence lies in the fact that the mixer will never let in hot water without first mixing it with cold water. For example, Gustavsberg faucets are equipped with a built-in Ecotemp lock. A characteristic click will indicate that the water temperature has reached 40 °C. Kludi, Grohe, VitrA, Roca, Hansgrohe, Noken and other manufacturers solve the problem of saving (10–15%) hot water differently. They offer “cold” opening models, in which cold water flows first when opening, rather than mixed water. To get warm or hot, you need to turn the knob to the left. Handle movement to the right is blocked.

The strictest controller of water consumption is a touchless faucet. Its body is equipped with an optical sensor (infrared sensor) of movement and an electronic module that activates the flow of water. The magnetic valve locks or releases the spout mixed water, the temperature of which is set in advance using an external lever regulator on the body or an adjustment screw built into the mixer. The mixer is powered by battery (6 V) or AC mains (230 V).

Often, the user does not assume that water can be saved by simply reconfiguring the cartridge (however, this is only included in single-lever models). Often, the economy mode is preset at the factory, but the user can adjust it independently during installation and even during operation to suit his needs. The lever and the protective plate must be removed. Then, using a screwdriver, tighten the screw that passes through the cartridge rod, which will limit the movement of the cartridge and, accordingly, the flow of water. For some manufacturers, reconfiguring the cartridge can also solve the problem of saving hot water.
It is estimated that 12 minutes of washing in the shower consumes 100 liters of water, but usually we spend half as much time and, accordingly, water on a hygienic morning shower. While we spend 140–200 liters of water to take a bath.

Looking at the ceiling watering can, you involuntarily ask the question: how much water do you need to use to feel the beauty of a real tropical downpour? When designing ceiling-mounted faucets, the same technologies are used as in faucets: mixing air, integrating devices into the shower head and even the hose (at Kludi) to regulate the flow of water. Thus, it is possible to save water by 60%.
For example, the huge Rainshower Jumbo (Grohe), whose diameter is 400 mm and the number of nozzles is 252, needs only 8.5 l/min to function and give the user the pleasure of water. Characteristic feature models of the Sensum (Roca) collection is the NightRain function: water is mixed with air, resulting in savings of 25–35% (compared to Rain mode).
Another device that allows you to reduce water consumption is an eco-jet. To operate the mechanism, the rotary ring on the watering can must be set to the Eco indicator. The water-saving mechanism in the shower head will block part of the water supply channels inside the latter. As a result, the flow volume will be reduced by 50%.

The optimal way to ensure comfort and save water and energy is a thermostatic mixer (thermostat). The thermostat control valve is equipped with a temperature limiter that prevents accidental water supply above 38 °C. If you want to take a hotter shower, you just need to release the lock by pressing a button. It is noteworthy that in the event of a sudden shutdown of cold water, the hot water supply will be blocked. When the supply is resumed, the mixer will immediately dispense water at the programmed temperature. This type of faucet is primarily relevant in the shower.

Most require 6 liters of water for complete cleaning. This is only for one flush, and even a small family flushes the toilet many times during the day. There is an exit.
Toilet bowls with dirt-repellent properties are ideal smooth surface(each manufacturer has its own secrets of cleanliness) allow you to reduce the use of chemicals by 80–90%, reduce the time for cleaning the device and save water.

The current EU standard is 6/3 liters of water: 6 liters for main and 3 liters for half. New products from leading manufacturers break stereotypes. For example, in the latest Villeroy & Boch models the standard is 4.5/3 l (including one liter clean water, providing additional reinforcement for flushing beyond the water seal). Gustavsberg products in Scandinavia come with settings of only 4/2 liters of water (regulators there do not require an additional liter of clean water when flushing). The same models are supplied to Russia with a 6/3 liter setting.

The innovative, so-called rimless design of the toilet bowl, which from different manufacturers was called Rimfree (Keramag), Rimless (Laufen), Rim-Ex (VitrA), DirectFlush (Villeroy & Boch), Rimove (Jacob), contributed to the hygiene of the device and saving water. Delafon), Hygienic Flush (Gustavsberg), Clean Rim (Roca), Clean On (Cersanit). Unlike a standard device, in this toilet the open edge (small protrusion) remains, but the inner edge in the bowl is removed). The flushing system with a powerful vortex flow in such toilets covers and cleans the entire toilet bowl. Given its power, this system is more economical. It is easier to keep the device clean; strong chemicals are not required. It is noteworthy that rimless toilets use 4/2 or 4.5/3 liters for flushing, resulting in water savings of about 30%.
Any modern faucet is equipped with a regular nozzle, which prevents water from splashing and makes the stream even. However, few people think about the fact that during operation, 12-15 liters of water flows out of the mixer per minute. This approach is extremely ineffective, because in order to wash your hands or brush your teeth you need much less liquid. A water-saving shower head will help make your water consumption more balanced and rational.
How it works?
Shower heads to save water physically limit the flow of liquid to 8 l/minute. This volume will be completely enough to satisfy your household needs. One way or another, they are connected to a faucet or to a water supply system, and the liquid flows through them. Water saving attachments can be used:
- on the kitchen faucet, which allows you to save water when cooking or washing food,
- on the washbasin to reduce water consumption when washing hands and brushing teeth,
- on the shower or on the bathroom faucet to minimize waste during each bath.
The installation of these nozzles is also relevant for owners of catering establishments, hotels and other establishments where it is impossible to constantly control water consumption. In most cases, installing a nozzle to reduce the flow yourself will not be difficult. It is enough to remove the standard nozzle and screw the economizer in its place. In the case of a shower, installation is done on a hose, and then a watering can is screwed to the nozzle itself.
Savers are divided into several types:
The shower aerator nozzle for saving water ranks first in popularity among various plumbing devices. It can be produced in all kinds of sizes and have all kinds of modifications. In some aerators, you can change the cross-section of the water flow by simply turning the nozzle. Others are equipped with a complex aeration system that fills the water with oxygen, but at the same time maintains its flushing ability. You can also purchase a water-saving shower aerator with lighting. In addition to saving water, they become an interesting element of the interior.
Aerators and other water-saving attachments should not be used if the pressure in the pipes is low. In such cases, the device will work very poorly or produce a jet with low pressure.
Sensor nozzles to save water
Touch attachments are multifunctional devices. In addition to significant savings, they allow you to forget about the problem of open taps, because liquid is supplied from them only if infrared sensor will feel warm. Another advantage of touch devices is hygiene. You do not need to touch the tap or any of its components with your hands, which will be useful when cooking. To ensure stable operation of the sensor attachments, you should replace the batteries every six months. The disadvantages of this device include its bulky appearance.
Magnetic nozzles to save water
This type of device is mounted on water meters. It acts on the anti-magnetic coupling installed inside the device and stops the counting of consumed water.
Magnetic attachments are produced from various materials: neodymium, iron, boron and other metals that can affect the antimagnetic field. They have an affordable price and are very easily fixed to the water meter body.
However, those who decide to purchase such a nozzle should be aware that any third-party impact on the water meter is a violation of the rules for using housing and communal services. And if magnets are found, you may be subject to a significant fine. It should be noted that a correctly selected magnet will not break the water meter, and after its removal the meter will function in standard mode.
Shower water limiters
This type of device is most often installed between the hose and the shower head. It significantly reduces pressure and reduces wastage of water. The water-saving shower head will be an excellent solution for large families, where bathing becomes as frequent a procedure as brushing your teeth. You should choose a limiter depending on what pressure is most comfortable for you, because it will no longer be possible to adjust it after installing the device. Depending on the model, the limiters can be 4, 6, 8 or 10 liters per minute.

An aerator for a faucet can be purchased at any hardware store or online When choosing a faucet for a bathroom or kitchen, pay attention to the aerator. What quality is it and how is it attached? In stores you can find a device with internal or external thread. Different kinds aerator nozzles allow you to choose best option for each.
Faucet aerator: its design and types
The faucet aerator nozzle consists of main parts. Inner and outer casings designed for assembling and installing the aerator. They allow you to install it on the faucet of a washbasin, sink or bathtub. The mesh limits the water pressure in the tap. And one more part - o-rings, which are necessary for a tight connection between the aerator and the tap. The faucet aerator is very popular among consumers. It is able not only to control the water pressure, but also to save it. When using it, water is saved 2-3 times.
Different types of aerator perform different functions. In addition to saving water, some can regulate the pressure of the jet, others saturate the water with oxygen, and still others purify the water from various large particles.
The faucet aerator may vary in shape and design
The types of aerator for the mixer can be:
- Vacuum,
- Turning,
- Aerator with lighting.
The rotary aerator is easy to use. It is the best of the above types. The nozzle can be made from different materials. Ceramic aerators are the highest quality and most durable; they have one drawback - they are expensive. Aerators made from plastic are cheaper and can last a long time. There may also be aerators made of stainless or chrome steel, but they are not durable. Aerators made of non-ferrous metals (bronze or brass) are also expensive.
Cleaning and replacing the shower aerator
An ineffective shower head is one of the main reasons for not saving water in the shower. To reduce water consumption, you need to limit the flow of water used. Currently, there are economical watering cans or attachments for them that allow you to save water.
A shower aerator is a modern invention that can save up to 50% of water. And it won't even be noticeable. Savings occur without compromising your comfort.
In order for the aerator to perform its functions, it must always be in good working order. Water currently contains a large number of various impurities, particles of salts, iron oxides. All this settles on the filter mesh and leads to contamination of the device, it stops functioning. To prevent this from happening, you need to clean the aerator in a timely manner.
Procedure for cleaning the aerator:
- Disassemble the aerator: wrench, use pliers or hand to unscrew it clockwise,
- Remove the cylinder with screens from the valve body,
- Disassemble the cylinder into all the parts it consists of,
- Clean the individual elements under a strong stream of water,
- Assemble and install in place.
Cleaning the aerator, as you can see, does not require much difficulty. You can do this very simply, with your own hands, without the help of specialists. Replacing the old nozzle is just as easy; you only need to have a new one on hand.
Beautiful aerator with lighting
If you are a connoisseur of any aesthetic little things, or you have small children, then you will like an aerator with lighting for the bathroom. They are made mainly from brass with a shiny finish. This design is complex. Inside the case there is a micro-turbine with an electric generator and a temperature sensor with diodes. This device does not require connection to an electrical network.
The illuminated aerator attaches to the faucet as easily as a regular one. You can screw it in by hand, without any special tools. When we open the tap, the jet illumination turns on automatically.
An illuminated aerator looks great on the Internet, made in high-tech or modern style
The color change of the jet depends on its temperature. The most heat such a nozzle should not be higher than 60 degrees.
Colors that are completely dependent on temperature:
- Green – its temperature is below 29 degrees,
- Blue – its temperature is from 30 to 38 degrees,
- Red – its temperature is higher than 39 degrees.
Such an aerator performs not only a decorative function, but also a practical one. It promptly signals changes in the temperature of the water in the tap. With lighting, the aerator will not leave either a child or an adult indifferent.
Flexible or rotating faucet aerator
Aerators always have a standard diameter, as well as a thread. To replace the device there are no problems, you just need to buy it in the store. If the mixer is unusual and has a rectangular spout, then of course a regular aerator will not work. You need a special repair kit for a particular crane model.
The rotary aerator for the mixer allows it to work in shower mode. Thanks to its hinged connection, the flow of water, consisting of many streams, can be redirected in any direction you want.
Among the advantages rotary aerator practicality should be noted
The rotary aerator is used not only for the bathroom, but also for the kitchen. Such aerators are installed to save water.
The aerator saves water consumption due to its following qualities:
- Increase the amount of water in the tap,
- The tip can be rotated 360 degrees,
- Eliminate contamination efficiently.
The rotary aerator can change the angle of inclination and force of the jet, and also allows you to select the mode of incoming water. The rotary aerator has two modes: a spray jet and a single jet. This aerator is very easy to use. A flexible aerator is used in the same way as a rotary one. Its peculiarity is that it is suspended from the tap on a hose. This allows you to collect water in any container. Even if it does not fit into the sink itself or is located at a distance from it.
Aerator – small, but very useful device, which allows you to save a considerable amount of water and is a coarse filter. It also saturates the water with oxygen, making it softer and more foamy. Helps eliminate the noise of flowing water. To some extent eliminates excess chlorine from water. And it hasn’t been invented yet in our time best device, the aerator combines durability and efficiency.

Not all people value water the same. In the arid corners of the planet, it is considered liquid gold, which is used only in the most necessary cases. In other countries, there is so much water that taking a bath for pleasure and relaxation is considered the norm.
And yet - even with free access to water, the idea of saving natural resources is becoming more and more popular. This implies not only a change of habits, but also the introduction of new technologies.
In Japan, where immersion in a deep tub is a national tradition, members of the same family take the same bath, not changing the water, but heating it. The Swedes went even further and proposed using one of NASA's technologies in the bathroom. So what ways to save water exist today? Below we've outlined several options, from high-tech faucets to small household tricks. Choose any one and join the movement for economical water consumption!
1. Reheat and use again
The Japanese are known for their penchant for lengthy water procedures, but relatives (or roommates) pour water into the ablution container only once - and then use it again. Japanese woman Anne Shimamoto says: “First you need to wash yourself thoroughly, and only then immerse yourself in hot bath. The water in the bath should remain clean and free of any traces of soap or shampoo to ensure that the next person feels comfortable. Since childhood, our parents taught us to take a bath correctly, it was an obligatory part of our upbringing.”Plus, many baths in Japanese houses are equipped with an “oidaki” system, which makes it possible to heat the water. If the bath has cooled down, you just need to press a button that turns on the boiler installed outside or in the utility room. The water is heated, allowing family members to take the same bath several times and significantly save water.
2. Turn to the latest technology
Resource conservation specialist and Marketing Director of the French branch of Hansgrohe, Eveline Stratmann, offers an innovative approach to introducing water-saving devices to the market. This approach is especially good where people are reluctant to give up the feeling of freely flowing water to save money. “The French are thrifty and strive to save on everything, but at the same time they are not ready to sacrifice comfort and change their everyday habits. Therefore, here water-saving plumbing should be introduced gently, unobtrusively and provide the same sensations during water procedures as conventional faucets and showers.”For Hansgrohe, the solution was the Rainmaker Select 460 3jetEcoSmart shower system, which has a secret weapon - the “Remember” button. When you press this button, the water temperature is automatically saved in the system, so the user does not have to waste time and, accordingly, pour excess water when he turns the shower back on. “We believe this innovation will help people break the habit of leaving the shower on during the entire wash process,” says Evelyn. ─ This is how we encourage people to soap up when the shower is turned off, because then they can instantly get water at the desired temperature, without wasting time on adjustments and without experiencing the unpleasant sensations of ice water or boiling water pouring under high pressure.”
But even if these innovations turn out to be effective and help save several liters of water, this will still not be enough for full savings. The fact is that the French are very fond of rain shower heads (they are also called rain shower heads), but they are the real culprits of excessive water consumption. “Therefore, despite all the new smart systems“, the first thing that needs to be changed is habits,” admits Evelyn.
Mikhail Chizhov, marketing director of the Russian branch of Hansgrohe, says that in Russia people have no special motivation to save water, since it can always be obtained in any quantity - and at a low price. “Water consumption in a regular sink faucet is about 13 l/min. All our basin mixers feature EcoSmart technology that reduces water consumption by 60%, i.e. up to 5 l/min. How does this happen? Thanks to air mixing and a special water flow limiter. The EcoSmart aerator, built into the faucet spout, enriches the water with air. The result is a rich, voluminous water jet.
As for shower heads, our line includes models both with water saving and without this function. The difference in price between the models is insignificant, but at the same time, 95% of watering cans sold in Russia do not have a water saving mode, says Mikhail. ─ This is because water in Russia is cheap, and buyers do not yet have the motivation to save water and consciously reduce its consumption - it is much more pleasant to take a “full” shower under a powerful stream.”
The installation of water meters in Russia has become mandatory since January 2015. Natalia Stogova says: “We installed water meters several years ago and did not expect that we would save so much as a result! The actual amount of water we use turned out to be 2-3 times less than what was indicated in the bill for average consumption.”
3. Buy a smaller bathtub or ditch it in favor of a shower.
Those who cannot imagine life without taking a bath can look for a small bowl with a volume of less than 270 liters. Others, like Danish user Jette Yde, are confident that they can do without it altogether: “I decided to go against the grain and say no to baths. This may be fun for children, but adults simply cannot justify such a reckless waste of natural resources. Water supplies are not endless, and I think that concern for the environment should be expressed at the household level. Therefore, remove bathtubs and install showers. There will be more space in the bathroom, and this decision will in any case be good for the environment and your wallet.”
4. Look to space for inspiration
It has long been known that space is not just an endless space somewhere out there, but also a fertile field for experiments and technological innovations, which are then returned to earth as inventions tested in the harshest conditions. One of latest developments in this area is a shower system from the Swedish company Orbital Systems, which saves 90% water and 80% energy compared to traditional showers.The invention is based on a joint science project, developed in 2013 by NASA and Orbital Systems founder Mehrdad Majoubi. At the time, Mehrdad was still a student and in his final year at Lund University in southern Sweden.
The idea was that the technology used to purify and reuse water on space stations could be used just as well on Earth - in both regular bathrooms and in public places: gyms, schools, baths and hotels. “It was an indescribable feeling,” says Mehrdad. ─ I found something that can be developed and used equally on earth and in space.”
Savings occur due to the fact that the same water passes through the filters and enters the shower system again and again. The cost of the basic “space” shower is $5,995 for a free-standing shower stall. A shower tray that is built into the floor during construction or major renovation will cost a thousand dollars less.
5. Collect what falls from the sky
In arid California, not only homeowners but also policymakers are concerned about how to reduce the amount of water required to maintain private gardens. According to the U.S. Environmental Protection Agency, about 30% of the water consumed by one person per day is spent on irrigation.Previously, according to local regulations, no more than 33% of plants requiring frequent watering could be planted in areas larger than 230 square meters. In 2015, the California Water Commission approved new rules that limited the number of lawns and other water-loving plants to 25% on new lots over 46 square meters and renovations over 230 square meters. For old plots with an area of less than 230 square meters, a list of restrictions was also introduced and necessary requirements. “It’s high time to review the law, because this is a joint initiative of residents and the administration. We're moving in the same direction with the new rules,” says Vicki Lake, program manager for the California Department of Water Resources.
Homeowners in all states are paying attention to how their gardens use water and are looking for ways to save. In May 2015, Houzz conducted a Landscape & Garden Trends study. Of the 1,600 users who had completed a landscaping project in the last 12 months, were in the process of renovating their property/garden, or planned to start in the next six months, water use reduction topped the list priority tasks. 70% of Californians who took part in the study noted the drought as main problem when implementing landscape projects.
One in five homeowners who are planning a garden renovation are planning to install a rainwater harvesting device on their property. 3% are considering installing a water purification system to use wastewater from bathrooms and laundry rooms for irrigation. "Two of our latest project were completely aimed at solving the problem of saving water,” says landscape designer Sara Warto from San Francisco.
Rainfall Shower Style Head High Efficiency Square Thin Water Saving Contemporary - $29.99
However, measures to reduce water consumption have affected not only Californian gardens, but also the homes themselves. Starting in July 2016, the only shower heads available in this state are those that flow no more than 11 liters of water per minute (2 liters less than before). This decision was approved by the California Energy Commission. In 2018, the limit will drop even lower - to 8 liters per minute. According to preliminary forecasts, this will save 11 billion liters of water in the first year and 173 billion liters in the next ten years.
6. Use simple but proven methods
A French specialist from RAAB Architecture offers several solutions that will help you start saving water in the bathroom today: “To start, just start using the water differently: turn it off when you soap yourself and brush your teeth. The most determined owners can put a bucket under the tap to collect the cold water that flows at the beginning. It can then be used not only for watering plants, but also for cooking. It is also worth buying an ordinary aerator for faucets (sold in hardware stores and construction stores). It restricts the flow and thus reduces water consumption by almost half. By the way, all modern mixers are equipped with it.”
Australian user Skyring architects suggests rescheduling long water treatments for the weekend: “If you like to stay in the shower longer, you shouldn’t deprive yourself of this pleasure. Just get into the habit of showering for four to five minutes on weekdays, and allow yourself to relax on the weekends.” In other words, before you take a shower next time, first go to the kitchen and grab a timer. Then, standing under the shower and listening to the inexorable ticking, you will begin to treat these minutes with all possible respect.
Following the Europeans, Russians are beginning to be more careful about water consumption. However, saving luxury is not a hindrance, and new plumbing products make this process easy, enjoyable and even fun.

Single lever mixers
Water saving nozzles. You can switch to an economical water consumption model using stop-start nozzles or an aerator mesh for an old mixer. Some SmartBoy nozzles are designed in such a way that when you turn the central rod, a maximum fixed water flow is set. Other models have the option to automatically stop water supply after 5-35 seconds. You can set the shutdown time yourself.
Using this mixer with an aerator, you can regulate the water flow (up to 2.5 l/min.).

Cold welcome. Another “smart” mechanism for the rational use of water from Roca is Cold Start. When the faucet is opened in the front position, only cold water flows from the tap. To get a mixed flow, you need to exit the economy mode.
Flow regulators. Hansgrohe EcoSmart technology limits the water flow for Hansgrohe and Ahog mixers to 5 l/min. (for comparison: previous generation models consume 14 l/min.). The water in these mixers is aerated: the air-saturated stream becomes softer and more voluminous. At high blood pressure the built-in ring-shaped flow restrictor becomes flat and partially blocks the culvert.
Restrictive cartridges. These latest control devices reduce water consumption by 50%. Thus, Roca Plus with Hidrocontrol technology gives you the choice between economical and maximum water flow. The mechanism is as follows: when raising the lever, the flow of water increases until the user feels the resistance of the elastic regulator. This is a sign of transition to the maximum flow rate mode.

A godsend for housewives. Water saving kitchen solution from the Kludi company, all of whose faucets are equipped with s-pointer eco aerators with a water flow rate of 6.5 l/min - Swing & Stop. You can turn off the water by turning the tap itself to the side, which is easily done even with your elbow. If you return the mixer to its original position, the water will flow again.
Electronic mixers. The basis for the operation of contactless faucets from the brands Oras, Hansgrohe, Roca, Kludi, Hansa, Gessi and others is a photocell that responds to hand movement. Water flows only when you raise your palms. Fixed temperature: 38 °C (thermostats - irreplaceable helpers in saving water and electricity), the miracle faucet operates in pulse mode using four AA batteries.
Economical shower heads
The solution from Grohe. Grohe EcoJoy ® technology provides both automatic and user-controlled water savings. And Rainshower ® shower heads with a diameter of 130 and 160 mm use 20% less water than standard counterparts.
Examples of shower heads with automatic water flow limitation.
Vitra solution. Vitra shower systems use water flow regulators that reduce the performance from 20 to 7-8 l/min. This results in a net water saving of 60%.
The solution from Hansgrohe. The air mixing function in EcoSmart technology limits water consumption to 6 l/min, which is 60% more economical than average, while maintaining the comfort of water procedures.

This hand shower head has three spray pressure modes - rain, massage and balanced (water is mixed with air bubbles). EcoSmart technology allows you to reduce water consumption to 9 l/min.
Economical shower cabins
Independent approach. The Templa Rubenus shower cabin from Ruben is equipped with its own pump. It does not depend on the pressure in the water supply system, and if a regular cabin spends 200-350 liters in hydromassage mode in 10 minutes, then the eco-option will only need 40 liters circulating between the watering can and the tray! The drawback of the system is the lack of disinfection and filtration.
Economical baths
Saving luxury is not a hindrance. Roca has developed an innovative solution for the whirlpool bath: In-Flow: 75 liters of water is enough for complete relaxation with hydromassage.

Only 75 liters of water for a full hydromassage - this smart bath with relaxing side cascades it can greatly save resources.
Circular drain. Toilets with this system supply water from multiple locations along the rim of the toilet, so effective cleaning occurs using much less water than traditional systems.

Economical toilets and urinals
Two drain modes. Economical models have two flush buttons on the tank, large and small. For example, Geberit built-in systems are equipped with a dual-volume flush (3 l/6 l) or flush/stop technology with manual interruption. The volume of both small and large flushes can be adjusted manually. The Ido company (Finland) offers the Trevi E toilet, which consumes only 4 liters with a large flush. Annual water savings with this model are 6.5 thousand liters per family member.
Thanks to the special siphon design, the urinal can be used without water connection.

Waterless urinals. In addition to models that use only 1 liter of water to flush, there are Subway urinals from Villeroy & Boch and Arkitekt from Vitra, which do not require water at all. The mechanism consists of a replaceable cartridge with hydraulic valve. The liquid in it is lighter than water, so waste and odors are completely absorbed.
Reuse of water. The development of the Roca W+W company (washbasin + wc - “sink + toilet”) is a monoblock of a sink and toilet with an odor filtration system. The essence of the concept is the ability to reuse water from the sink to fill the toilet tank. Water savings - 25%.

When choosing a mixer for modern kitchen most prefer functional and stylish single-lever models. Let's talk about their varieties and features.
How to create a SPA at home with minimal funds? What kind of shower do men need and what kind do women need? About what to pay attention to to make the bathroom as comfortable as possible.
A sparkling clean bathtub, a dazzling toilet, sparkling taps - these days this ideal picture is achievable without much effort. All thanks to plumbing fixtures with a dirt-repellent coating.
Modern bathrooms are increasingly equipped with wall-hung sanitary ware. There is no other way to install it than using the installation system. Let's talk about the nuances of choosing a hidden installation system.
“Typically, 20% of the water in time is an absolute loss,” says Jonah Schein, technical coordinator for the WaterSense Homes and Buildings program. This program is developed by the US Environmental Protection Agency and aims to promote water efficiency.
The shower accounts for about 17% of the water in the home, and the average American family uses about 160 liters of water per day in the shower. This amounts to 4.8 trillion liters of water annually in the United States alone. According to WaterSense, “this amount is enough to completely supply New York and New Jersey with water for a similar period of time.” If you lose 20% each time, then that’s more than 700 billion liters that are wasted, and somewhere in the world entire countries are suffering from drought and water shortages.
Moreover, we are all accustomed to taking showers, and the shower head only contributes to heat loss, so showering is a very energy-intensive process.
In total, there are three types of losses: water, and, of course, money.
Surprisingly, the reasons for most of these losses are purely behavioral. Before taking a shower, people wait for hot water (which can take a while, especially if the water heater is far away) and so they flush the water. At this stage this is a constructive problem and all we can do is convince people to accept cold shower(not such a bad idea), but it won't make much of a difference. The problem is that even after filing hot people They don’t start taking a shower right away and just spend some time wasted. This is a behavioral problem.
Educating people about the consequences of habitual behavior will probably change the situation in some cases, but in reality it is very difficult to change the routine, especially when there is visually no problem.
Therefore, a lot of attention is now being paid to various things. Among them we note the thermostatic shut-off valve.
Thermostatic valves are already used in fashionable versions of shower stalls to regulate water temperature, ensure that the combination of hot and cold water remains constant and prevent scalding if for some reason the cold water stops flowing. But a thermostatic shut-off valve does something else: it allows water to flow until it reaches a certain temperature, and then stops the flow until you reopen the valve.
The valve can be built into the shower head, or it can be removable.
A removable valve must be installed on the pipe in front of the shower head; it automatically records all typical losses during showering, without causing any inconvenience to the user. You will still be able to get into the shower with hot water, all you need to do is open the valve again.
The video below demonstrates the easy installation and use method.
