It is not enough just to drill a source in a personal plot. It needs to be equipped properly. Well casing is an important and integral stage, which is approached with full responsibility. Before starting work, they become familiar with the types of strapping, each of which differs in functionality, reliability and price.
What is the wellhead piping for?
The piping is a complex of engineering works that ensure an effective connection to the water supply system, as well as the uninterrupted and unimpeded operation of a submersible or surface pump.
As a rule, after carrying out the work, it is possible to solve the following tasks:
- Protection of the autonomous water supply network from freezing with the arrival of cold weather.
- Arrangement of a suitable place for pumping equipment, where you can easily approach for maintenance and repair of equipment.
- Protecting the casing from negative environmental influences, such as precipitation, debris.
- Connection of the pressure pipe from the electric pump to the water supply network.
In conclusion, you need to lower the submersible pump to the required depth, which will effectively raise water to the surface without losing the productivity and power of the pumping station.
The well tie-in process has a list of requirements. The necessary conditions:
- Installation of the caisson directly at the wellhead or the top of the casing.
- Selection of pumping equipment and its installation, it is also important to take care of providing the system with power.
- Digging trenches, as well as laying pipes in them to water intake points in strict accordance with the project.
- Installation of main and auxiliary equipment, which was not previously equipped with a caisson.
The most important requirement is that all actions are carried out in a strict sequence, otherwise there is a risk that expensive equipment will fail.
Required list of equipment and parts
The organization of autonomous water supply for a country house includes mandatory equipment and tools. The main ones are:
- Submersible and surface water pump. When the depth of water in the well is large, it is recommended to give preference to centrifugal models.
- Casing pipe fitted with pump mountings. They come in the form of a regular pipe from a surface water pump, adapter, or wellhead.
- Pipeline. As a rule, specialists give preference to pipes made of low pressure polyethylene. The material has many advantageous features: strength, durability, ease of installation and reasonable cost.
- Automation, which includes an idle and pressure switch, filters, a pressure gauge and a hydraulic accumulator. If we are talking about surface models of pumping equipment, then they are initially equipped with automation.
Also, for the operation of the water supply network, ball valves, couplings and fittings are required.
An example of a water well piping scheme
The duration of the well operation depends on the correctness of the design work and the quality of the piping fabrication. It is at the design stage that it is important to take into account all the features of water consumption, based on the required volumes, climatic conditions of the region and the depth of water occurrence.
The standard piping scheme includes the following:
- manufacture of an adapter, caisson or pit;
- design (drawing up) and installation of a water supply network;
- search for suitable pumping equipment and filters;
- installation of a hydraulic accumulator;
- installation of a submersible or surface water pump;
- trial run of autonomous water supply.
There are three main methods for arranging the water outlet to the surface: adapter, caisson and pit. It is also possible to erect a ground building near the place of water intake, but this is advisable only when living in warm regions. In the central and northern regions, the building needs to be heated with the arrival of winter.
Arrangement of a well on a personal plot is a responsible business. The quality of the water, as well as the efficiency and duration of operation of the autonomous water intake network, will depend on the correct choice of the location for drilling the well and further arrangement.
Injection equipment plays a great role in the work; it is chosen based on the needs and characteristics of the well. The heavy duty pump will run "idle", which will cause rapid wear of parts. Insufficient performance will work continuously, which will lead to overheating of the engine and its combustion.
