How to install a water supply system in a country house?

Neither in picturesque village houses, nor even more so in country cottages, life without water is impossible. This is known to each of us Missions "eat", "drink", "wash", "wash" simply not feasible in the absence of water supply =/ Today we strive to spend most of our time outside the city, some live there permanently Let's consider some of the options for solving such a vital issue, we will not ignore the differences inherent in them

The solution to the problem of water supply makes sense, provided that a source of water is available. The proximity of some reservoir will make life easier: armed with buckets, wasting time and effort, you can create a certain supply of water for your own needs. And in the case when it (source ) is difficult to access or does not exist at all, the situation needs to be corrected

For summer cottages and personal plots, it is customary to consider two designs for "extraction"; water – artesian well and well Artesian well – a conventional borehole for lifting underground water lying in aquifers of hard rocks It is possible to accelerate the rise of water using a pump Well – this is a dug-out mine, to strengthen the walls of which reinforced concrete rings or a log house are used. The walls of the well can also be strengthened with ordinary brickwork

What to choose? Any solution to this issue – a special case, taking into account the characteristics of the site

Advantages of an artesian well

It can be drilled in any place where water is present. First of all, underground water is used for drinking purposes, since, as a rule, it does not require forced purification, and in some cases – disinfection In addition, it is free from nitrates, radionuclides and other harmful combinations, which increases its value to humans. Today, use an artesian well as a source of water – very reliable, popular and prestigious option for independent water supply in country houses

Her shortcomings

The depth of drilling a well is influenced by two factors - the depth of the water layer and the quality of the water in it. It is impossible to carry out these works without hiring professionals, which will undoubtedly affect the budget

The advantages of a shaft well

You can dig a well yourself By asking informed and experienced local residents in this matter, you can invite them to help It will cost less than the official hiring of specialistsIt is possible that the water of the upper layer will be at least not very clean. It may be exceptional throughout the district, and you have – with impurities, and even with a smell Over time, any well becomes silted up, which significantly reduces the water level

In the village water supply system, sometimes there are disturbances in the supply of water And with its massive intake for irrigation of garden plots, especially during the hot summer months, the system pressure is significantly reduced For the owner of a cottage with a large amount of household equipment from a water heater to a dishwasher, the threat of failure becomes real of all these units from work, and the water supply system itself can be depressurized. For the most part, they are sensitive precisely to pressure drops in the water supply network

The main components of a continuous water supply are a storage tank and a pump with automatic on-off operation. Any of the above structures is used as a water source: a well, a well, a centralized system. The storage tank is filled with a pump, the automatic system of which is equipped with water level sensors. Even elementary knowledge of electrical engineering will help you do this without much difficulty

If you have decided to live permanently outside the city, then the automatic water supply system will save you and your family members from numerous worries and inconveniences

For automatic water supply by an intra-house system, it is advisable to connect a hydrophore to a water storage tank Hydrofor – small capacity of membrane type – belongs to the category of water-pressure devices and is equipped with an electric motor, a water pump, a hydraulic accumulator (an approximate analogue of an expansion tank), a pressure gauge and a pressure switch. The principle of its operation is quite simple: the water in the system enters the storage tank. and into the rubber membrane At normal pressure in the water supply system, water is taken without replenishment, with a decrease in pressure, the accumulated reserve is consumed

A little about the storage tank It must be installed above the level of consumption points. In the event of a power outage, the pump will stop working, and the water from the tank will reach the right place by gravity

What seems impossible at first glance, it is quite possible to implement in practice. It is only important to choose the right direction

Decentralization of heat supply - salvation for housing and communal services

Despite the wealth of natural energy resources that our country is famous for, they do not even think of getting cheaper. As they approach the level of world prices, the problem of energy saving becomes more and more relevant, because the future of the domestic economy is largely determined by this parameter.
