Plumbing is one of the main facilities in a residential building. Competent approach combines housing design with optimal engineering solutions. Therefore, our task is to create an individual project of a water supply system for your house or apartment.
Water supply design is necessary to ensure the supply of water to a house or apartment, considering the main factors – the amount of consumption and the characteristics of sanitary ware (plumbing).
The whole process of water supply can be divided into two types – external and internal.
External water supply – these are communications through which water enters private houses and apartments. For apartment buildings, water is supplied from the central city pipeline. It is cleaned according to certain sanitary standards and supplied to the residential sector. For private houses, as a rule, water from an artificial well is used, which is supplied to a boiler station, and then is distributed throughout the house.
Internal water supply is the circulation of water within the building itself. The task of design in this case is to make sure that water moves through the pipes without problems in the required volume and complies with the design solutions of your home. It is also important to understand that the plumbing system is inextricably linked with the sewerage system.
Alter Air company designs internal water supply systems and implements effective engineering solutions for apartments and private houses.
To design an internal plumbing in an apartment or house, you need to consider several factors that will form the basis of engineering calculations. Water supply design considers:
the number of people living,
the number of “water supply points”,
plumbing development.
Depending on these parameters, it is necessary to calculate the features of the piping, as well as the amount of water that will be required for permanent use. For example, if there are two people in a family and one bathroom point, we understand that the shower will be used in turn. In this case, water consumption is calculated per person, which is approximately 30-40 l / min. However, if there are two bathrooms in which residents take a shower at the same time, the flow rate will be already 60-80 l / min. The difference is noticeable, and this load on the pipelines must be considered.
A plumbing development is a clear list of what plumbing will be used in a particular apartment according to a design project. Why is it important? In plumbing, there are certain key points. For example, at what height should the bathroom sink faucet be located or where the hidden parts of the shower system (temperature controls, mode switches) will be installed.
It is necessary to clearly understand where exactly they are in the design project to correctly lay the pipelines at the construction stage. Only then you can install the visible parts of the plumbing and add new ones if necessary (for example, over time you will need to add another shower head for a child or an additional faucet under the bathroom sink).
It is significant to consider that the diameters of pipelines for plumbing are also selected based on water consumption. After all, for example, one shower head can consume 36 liters of water, and the other – 12 liters. If you choose the wrong piping system, a pressure drop situation can arise: when you take a shower in one bathroom, and the water pressure drops sharply when someone opens a tap in another area.
There are two types of piping:
Plumbing design also includes the Neptune water leakage protection system. Special sensors identify the leak and automatically shut off the water supply. In the case of a dead-end wiring, the water will be blocked to all “wet zones”, and with a radial system, only the branch where the problem is detected will be blocked.
The installation teams of Alter Air implement the final project.
According to state construction norms and regulations, the most important thing is to combine the design project for plumbing with water consumption calculations. The plumbing is designed in such a way that it considers the number of people living and passes as much water as needed for a particular device and the built-in parts that they have (washbasins, bathtubs, shower systems).
Usually, water comes to private houses from wells. These wells are made by individual companies, which, because of maps of regional resources, determine the location of a high-quality water layer. By “quality layer” we mean water with a minimum number of impurities – minerals, salts, and iron. However, without technical water treatment, it cannot be used in the household segment.
Therefore, before implementing water distribution in a private house, it must first be cleaned and softened. The treatment system is selected based on the results of water quality analysis. If it has an increased level of iron content, a water iron removal system is additionally installed. Thus, the technical purification of water from a well will consist of two parts: iron removal and softening. However, even after these stages, you cannot drink it.
The water supply to the apartment is limited by the norms of city water supply. Water is supplied to a multistory building in a volume calculated for the number of apartments and the people living in them. The piping layout is standardized, so it is impossible to influence the water pressure and regulate the pressure.
As we said at the beginning, water enters the multistory buildings from the Kyiv city water supply system – either from wells or from the Dnipro River. Connection and design of the water supply system is not implemented without water treatment. The state is obliged to purify the extracted water and make it suitable for use. Minerals, salts, iron are removed from it, but the water is not made “soft”.
At the household level, we notice this in the form of scale in the kettle or when we have dry skin after a shower. Therefore, for apartments it is necessary to apply additional cleaning and softening, and only then distribute it through new pipes.
We receive main information from customers, on which the calculations and design features depend. It is important for us to understand how many people will use plumbing, what kind of plumbing will be installed in the house.
Based on the input information, we calculate the required amount of water for the house, consider the requirements of the plumbing project, and select a hydraulic system—dead-end or radial.
At this stage, we create a ready-made plan for installation work. The water supply project considers the requirements for water consumption and combines the design project of the house with optimal engineering solutions.
The selection of components for piping is carried out in parallel with the development of the project. These are inseparable processes that must be coordinated with each other.
The price for designing water supply systems depends on the so-called “water supply points”, that is, the points of water outlets in the house. The price includes a water supply and sewerage project.

This allows you to take into account the smallest details of the project, speed up and simplify the process - one team will work on the object, which has thoroughly studied all its details and features. For each system, we select the best lighting equipment that can integrate into other systems in your home - for example, Smart Home.
Full integration, automation and easy control - we do everything for your maximum comfort.
The supply and exhaust ventilation system with heat and moisture recovery assumes the supply of fresh air to the premises and the removal of waste air. At the same time, it allows you to save up to 70% on heating, since with help of an enthalpy recuperator it heats and humidifies the supply streams due to heat and moisture taken from removed streams. The air circulates through the duct system, which are installed during the construction phase or during the renovation process. Air distribution is carried out using slot diffusers or ventilation grilles. As the most functional and efficient solution to date, we recommend supply and exhaust ventilation based on a VAV system, which allows large volumes of air to be supplied locally to those rooms where people are, while maintaining the air balance in the rest of the rooms.
For implementation of ventilation system, we use round galvanized steel (tin) air ducts. Due to circular cross-section, the minimum air resistance is ensured, which means less noise during the operation of the system. Such air ducts are easy to install and maintain, while providing high-quality air exchange in household and commercial facilities. In our projects we use tin air ducts of our own production.
For air distribution throughout the room, concealed slot diffusers are used, which are completely invisible in the interior. This is a stylish and extremely popular solution. In projects, we prefer linear diffusers from the TROX and Disair brands. A simpler and more economical option is to use ventilation grilles. They are more noticeable, however, they are realized in different sizes and colors, you can choose the most suitable for your interior design.
Plenum box is one of the important elements of the round duct system, which connects them to air distribution devices: grilles, diffusers or anemostats. Plenum boxes are made of galvanized steel and installed both for supply and for air intake - they are shown in diagram in blue and red, respectively. Suitable for all types of ceiling systems, can be insulated if necessary.
In our projects, we prefer to use a ducted air conditioning system. There are a number of reasons for this: duct air conditioners distribute chilled air flows more efficiently without creating drafts, moreover, they are hidden as much as possible in the interior, as they are mounted in the ceiling space. Air is supplied through ventilation grilles or slot diffusers. They can be installed in technical and household premises in order not to lower the ceilings in living rooms. We recommend paying attention to Daikin duct air conditioners as one of the highest quality and most efficient on the market.
The heat pump can act as a source of heat in the heating system - as the most efficient and energy-efficient unit. You can also consider a gas condensing boiler (as a more advanced type of gas boiler) or an electric boiler - as a fairly inexpensive and affordable option. The latter also has the advantage that it can be installed as an intermediate solution before purchasing a heat pump. When implementing heating, Alter Air experts recommend giving preference to an air-to-water heat pump, since it uses renewable resources, helps to save energy and can be used for hot water supply and even air conditioning (together with fan coil units).
For efficient space heating in frosty weather, we use floor convectors, for example, models from the Kampmann and Kermi brands. They are installed in the floor and only an inconspicuous grille remains outside. Heat is supplied from the bottom up, which makes heating as efficient as possible. Floor convectors are especially recommended for use near panoramic windows and in places with low window sills, they prevent cold air from entering the rooms, heat the room with high quality and at the same time preserve the aesthetics and style of the interior.
Underfloor heating is a low-temperature heat source. For comfortable use, it should not heat up to more than 26 ° C. We recommend the installation of underfloor heating to all our customers. The most optimal areas of application are bathrooms, bathroom, bedroom. Since the temperature of the underfloor heating cannot exceed the value indicated above, it is rational to connect heating using radiators or convectors in the event of frost. Together with the underfloor heating system, they will effectively heat the premises. You can always set the desired temperature yourself and further adjust it.
Organization of the water supply system to a large extent depends on the chosen equipment. XLPE pipes are considered quite effective. In our projects, we prefer to use the world famous brands Uponor, NanoFlex and GofraFlex. They are characterized by increased strength, great flexibility and 100% protection against oxygen permeability.
Before choosing a water treatment system for a house or apartment, you should send a water sample for analysis. Based on the results obtained, Alter Air specialists will select a water treatment system that will solve the existing problems. The system can include a filter to soften water, to remove iron, chlorine, hydrogen sulfide, organic impurities. If necessary, you can connect ultraviolet disinfection. Such a system is an absolute necessity for houses and apartments, if the owners do not want breakdowns of household appliances and climatic equipment that uses water, an unpleasant sensation on the hair and skin, and spoiled clothes. Modern Ecosoft systems are easy to maintain, and our company's specialists will accurately select the right system for your house or apartment.
We design a power supply system depending on your needs: standard, lighting on programmable relays, or we implement an integrated Smart Home system with the ability to remotely control all systems. All we need is to know your preferences for the placement of switches, sockets, blinds, know the power input and have a measurement plan.
The automation system allows you to control - both personally and remotely - all systems in your home. It can be either only lighting (automatic light switching on and off, additional lighting and dimming), or full control of all climatic systems: air conditioning, heating, ventilation. You can also control alarms, surveillance cameras, household appliances. Everything can be switched on and off at your request completely remotely. We will help you design and install a turnkey automation system.
The use of solar PV modules and wind turbines is gaining more and more popularity in Ukraine. Of course, we do not stand aside and our portfolio contains a sufficient number of projects for the implementation of alternative energy systems. However, this is a rather expensive service and its expediency must be assessed. Indeed, from November to March it will be extremely difficult to obtain a sufficient amount of solar energy, and the installation of a wind generator generally requires six months of observations of the terrain and complex calculations. Therefore, we consider the installation of an air-to-water heat pump as the most optimal in terms of efficiency and budget, which also uses the inexhaustible resources of nature.
In swimming pools, it is important to maintain high-quality air exchange, preventing moisture from constantly concentrating in the room. For this we use Calorex and Dantherm pool dehumidifiers. To ensure the supply of fresh air sufficient for the stay of the required number of people in the pool, as well as the intake of exhaust air, we use supply and exhaust ventilation without heat recovery. Why not? Because there is a high risk that the heat exchanger will freeze up due to the high humidity of the extract air.
We will select for you and install high-quality sanitary ware of European brands: Duravit, Agape or any other of whose quality we have no doubts. Bathtubs and shower trays from these manufacturers are an example of grace, elegance and attention to detail. Do you have a minimalistic interior? We have different solutions!
We will select for you stylish high-quality sanitary ware - toilets and bidets of famous world brands. Among them are the aesthetic Cielo, the elegant and minimalist Antonio Lupi and others. We deliver and install all selected plumbing fixtures ourselves.
Washbasins, taps and shower systems from Hansgrohe, Cristina and CEA Design complement your bathroom design and add interesting details. We will select, deliver and assemble all your chosen plumbing elements!

Highly efficient air handling unit for general ventilation in houses and apartments. Reuses the heat and moisture that are present in the room. Has a "native" VAV-system (variable air supply).
Double-slot diffusers from the TROX brand are designed for high-quality air distribution throughout the room. They combine visual aesthetics and high technical potential. Air currents are given in different directions, evenly scattering and avoiding any drafts. Outwardly, only laconic lines on the ceiling remain visible.
A low-pressure internal duct unit Daikin FDXM 35F is installed in the ceiling space of the bathroom - it works to cool the bedroom. It is accessed through hatches. The capacity of the air conditioner is enough to service rooms up to 35 m2, which is optimal for a given room. The lowering of the ceiling in a technical room was 300 mm.
Vertical indirect heating boiler Drazice OKSE 200 l is designed to provide apartment residents with hot water. The inner surface of the tank is covered with high-quality enamel without nickel, which ensures a long operation of the water heater, and there is also an anti-corrosion coating. The temperature inside can be kept between 7 and 77 ℃. The water heating indicator always shows the current temperature on the front of the tank. There is a fast heating function. This is an excellent solution for an apartment, allowing you not to depend on seasonal blackouts and other inconveniences.
Electric boiler Vaillant Ecoblock An electric boiler Vaillant Ecoblock with a capacity of 6 kW and efficiency of up to 99% works for heating and hot water supply of the entire apartment. It has a wide range of temperature settings for both heating and hot water supply. There are frost protection and 2-level overheating protection. Equipped with eBus data transmission technology. With the help of a capillary thermostat, residents can smoothly regulate the heating temperature in the range from 25 to 85 ℃
The Zilmet expansion tank is designed to compensate extra pressure in the heating system. Works in conjunction with the Vaillant electric boiler above. The special inner lining of the tank prevents the growth of any bacteria, that is, the water does not acquire a metallic taste, does not stagnate or change its properties.
A modern system for filtering and softening water: cleans water from all kinds of impurities and odors, neutralizes iron, making it soft, pleasant and safe for household appliances, water pipes and human use. The purified water is also suitable for drinking directly from the tap. The refiner does not require changing the carbon filters, and is controlled via WiFi - maximum automation and comfort!
It is necessary to make a project for water supply at the construction stage, taking into account three factors: the number of people, the number of “water supply points” and the location of sanitary ware (plumbing). When installing a water supply system, there should be clear bindings for plumbing, in which there will be a combined design project and engineering solutions. For example, at what height the faucet and its handles should be, what distance from the sink and what distance from the cabinet or other furniture or how to install an asymmetric bathroom sink faucet. All these key parameters must be calculated in advance and to the smallest detail, so that in the future you do not have to remove tiles, pipes, or change plumbing.
Therefore, to make water supply for housing (a house or an apartment), two factors must be agreed – a competent design project (especially in terms of plumbing) and the choice of a company that will design the water supply to meet these requirements. In the process of developing a design project, you should pay attention to visual solutions for plumbing and the cost of materials that will suit you. In addition, when the project is ready, you can contact Alter Air to install the optimal plumbing system.
The main difference is that it is impossible to change the water pressure in a water supply system in an apartment. City water supply provides a specific volume of water through a pipeline of a certain diameter, which cannot be changed. Therefore, when buying an apartment, you should always pay attention to what pipelines were installed, materials used and what is the real water pressure in the house.
In a private house, water comes from a well, and the pressure can be regulated by a submersible pump. The diameter of the pipeline is selected independently considering the necessary plumbing so that there are no problems in the future.
The cost of the project should be calculated individually.
If we focus on the average cost of design (excluding installation and materials), we can talk about 15,000 UAH for an area of 100 m2. The price of the water supply project of a private house and an apartment is approximately the same.
