How to draw water from the well to the house? Well water supply
A well from ancient times is a reliable and convenient artificial source of water. Modern technology allows you to make it convenient delivery directly to the places of use, for example, in the bathroom or in the kitchen. In the absence of electricity, only a well is able to provide the house with water at the expense of traditional gates, chains and buckets.With rare visits to the building and small consumption, this method may be the main. Leaving it as a reserve, in any case, you need to figure out how to draw water from the well to the house.
The well is protected from the ice plug by a warm lid installed below the frost penetration depth. It can be made of moisture resistant plywood, and then lowered and secured on hangers. It is possible to use in addition modern heat-insulating materials, having covered wood with expanded polystyrene. Approximately 1 meter above install the next cover.It should also be insulated and fit snugly to the base. Above the well is mounted a well-built log cabin with a top, which are also protection from the cold. The wooden walls of the mine themselves are heat insulators. In the construction of a well of concrete or brick, the upper part can be pasted on the inside with penofol 10 mm thick, with foil to the outside.
Water filtration in the well
To solve the problem of how to conduct water into the house so that pollution does not get into the system with it, you can filter it in the well. A simple device made of charged natural materials will allow the separation of mechanical impurities that can destroy the pump. Water needs to be cleaned, for which reason bottom filters are used. For loose clay bottom make a direct filter. Stones are laid on the bottom, then rubble, and river pebbles are poured on it. Each layer should be about 15 cm thick. For a sandy bottom, use a return filter with three layers of 15 cm. Below is sand, river pebbles are poured on it, and the largest stones are placed on top. Once a year, filters are cleaned, taking out and washing the stones, and also replace small fractions.
Winter and summer water supply options
The dwelling can be supplied according to the summer and winter schemes. To conduct water to a private house in the first embodiment is the easiest. The pipes are laid on the ground or shallowly buried. As a rule, this is a temporary solution.
How to water the house for all-season use? To do this, the pipeline should be located below the depth of frost penetration. The water in the house from the well should not only be supplied, but also be drained back from the entire system when needed.To this end, the installation of a crane at the bottom point is provided on the pipeline. In such cases, it is preferable to use a submersible pump that provides rapid filling of the system and raising the operating pressure.
Also need a permanent summer water supply for the garden. To do this, out of the house, from the manifold of the pressure line is output outside and is connected to the irrigation system. For the winter, it turns off, and water is drained from it.
Pump station selection
The way how to conduct water in a private house depends on the depth of its location. If the level is above 10 m, a pump station is used. It is located in the house and pumps water into the system along a sufficiently long suction pipe lowered into the well.Solving the problem "how to conduct water from the well to the house," you need to choose how to accumulate it. To do this, use the pressure tank included in the pump station. It consists of two parts separated by a membrane, one of which contains compressed air. When water is pumped into one half, the volume of the other decreases. When the set pressure is reached, the station pump is turned off. The check valve closes and water is retained in the system. As it is used, the pressure decreases, and the station is switched on again, adding a new batch. There is another version of the pressure tank in the form of an elastic pear, which is filled with water. It is located inside the tank with pressurized air. The advantage of the design is the absence of metal contact with water, which increases its service life. The pump is turned on at a pressure in the system of 1.7 atm and switched off at 3 atm. It can be changed by setting up a special relay and pumping air into the tank through the car nipple mounted on it.
Which pump to choose?
The pump for water, in the well supplied, may be of a vortex or centrifugal type.
Many choose it only for two indicators - pressure and flow. This is clearly not enough. An important indicator is the optimum height to which the pump can lift water. It is in the range of 6-10 m. Usability depends on the type of suction. Conventional pumps require complete liquid filling of the system. Self-priming type, when water is suitable due to the created vacuum, more convenient. But at the same time the pump creates less pressure than normal.
Water supply to the house
The pumping station should be installed in a house, basement or room in which there is no negative temperature. Water is supplied to the house through HDPE pipes (low pressure polyethylene) with a diameter of 32 mm. They should be chosen for the drinking variety (black with blue stripes). Before taking the water from the well to the house, you should dig a trench below the freezing depth. It should be evenly tilted toward the well for easy drainage of fluid from the system. The pipe enters the house under the foundation or through the basement and is connected to the pumping station. A hole is punched through the concrete with a jackhammer or perforator.Before you take the water into the house, a sleeve of larger diameter is inserted into the basement wall. And through it the pipeline is passed. This place is then sealed to protect against the ingress of water from outside. The other end is inserted through a hole drilled in the concrete ring to the inside of the well.
A heating cable can be attached to the pipe with adhesive tape. It should be electrically sealed near the well, and the other end connected to the panel inside the house. All this is placed in a cylindrical insulation, which also compensates for shrinkage of the soil after instillation.
Before you order the manufacture of the well, you need to know its value. You can conduct water into the house yourself, which will make it possible to save money. The price of the finished well will be 30-50 thousand rubles, which is several times cheaper compared to drilling a well. In addition, the project should be ordered from the specialists and installation of water supply in the house This will greatly facilitate the operation and maintenance of it in the future.
Together with the water supply system into the well, the individual pipes for connecting the PND of smaller diameters are laid to connect the outlet sockets inside the well and the submersible pump, if later it becomes necessary to install it. To do this, two more holes are drilled in the ring.Electrical wiring to the well can be brought to a shallow depth, which subsequently will facilitate its repair or replacement. Wire cross section is selected by the maximum power of the connected consumer. All connections must be protected from moisture.
Waterproof socket mounted under the tip. It is possible to connect a lantern to maintain the well, as well as an independent submersible pump, if it becomes necessary to resolve the issue of how to conduct water from the well to the house or the site in another way.
Sealing of inputs to the well
The trench is buried with sand, and all openings are sealed with a quick-hardening solution (hydraulic seal, cement with liquid glass, silicone sealant). Transitions through the wall of the well will be more reliable if metal pipes (strains) are installed in them, fixed on both sides by flanges. The water supply is connected to the fitting.
Depth of water intake
The end of the pipe, immersed in the well, should be at a level of 20-30 cm from the bottom. The dynamic level must be higher to prevent air from entering the system. If it is lower, a method should be provided to automatically shut off the pump when the minimum liquid limit is reached.The water supply from the well will be more reliable if a strainer is attached to the suction end of the pipeline. There should also be ensured that the entire system is drained with an additional tap.
When laying water from the well to the house, it is necessary to ensure its reliable insulation, bottom filtration, placement of pipes below the ground freezing point and use of a pressure tank with a reliable pump station.
