To provide country houses with water, many owners drill holes. To protect the site of water intake and equipment for water supply, installed caissons. They are a sealed tank in which a dry microclimate is created, and in winter a positive temperature is maintained. Today there are different options for the installation of protective structures for wells. Experts recommend to pay attention to several nuances.
- The first step is to determine the size of the tank. For one pump that pumps water, the smallest reservoir will do. But if additional equipment for accumulation or water treatment is installed inside, the dimensions of the caisson can be comparable with a small utility room.
- Concrete and brick tanks go to the past. Today, homeowners often prefer steel or plastic models. If it is better to put metal structures at the construction stage, then light plastic tanks can be mounted manually, even in dense building conditions.
- For the northern regions, where there are severe frosts in winter, it is important to choose a caisson with a warm lid. It is through it that the cold penetrates, often the water freezes, and the equipment fails.
Our review includes 5 best caissons for the well. In compiling the rating, expert opinion and homeowner reviews were taken into account.
Top metal caissons

A country: Russia
Average price: 22 209 rub.
Rating (2019): 4.7
In the conditions of severe Russian winter, it is important to prevent freezing of water. Therefore, the designers of the Rolling Plant developed a metal caisson with a heat-insulating cover. This approach allowed us to normalize the temperature inside the tank, to prevent the formation of condensate and freezing. The model is made of steel 4 mm thick, to protect against corrosion, the manufacturer has applied the Kuzbasslak proven for decades (BT-577). The overall dimensions of the caisson (2x1x1 m) allow you to insert into it a storage tank with a capacity of 100 liters, as well as a ladder to service the equipment. To facilitate the installation and fixation of the steel tank, there are special mounting brackets.
Users note the reliable thermal insulation of the caisson, which provides a cover with foam. Among the shortcomings is the absence of a liner for the casing, there are also no loops for closing the cover.

Domestic manufacturer Akvolux Plast managed to create the easiest caisson. Its mass is only 60 kg. Such a tank can be easily transferred and installed together. Moreover, the manufacturer has provided special eyelets that facilitate installation and transportation. Particularly relevant is the low weight, when there is no possibility to use special equipment due to the density of the building. The body is made of plastic with a thickness of 6 mm, and the bottom is made in a reinforced version (8 mm). Thanks to the skirt at the bottom of the caisson, it is possible to securely lock the container in the ground and prevent it from being pushed out.

Rating (2019): 4.9
The high level of tightness of the space around the well is provided by the plastic caisson Triton. Condensate does not form inside the tank, reliable thermal insulation maintains a positive temperature. All these important qualities are achieved by engineers of the domestic company Expocom-Plast through the use of polypropylene. The material has the necessary strength, and the corrosion and oxidation owners caisson can be forgotten. The model has a cylindrical shape (height 2 m, diameter 0.96 m), there is a plastic tank and neck (0.5 x 0.7 m). For durability, stiffening ribs are installed, and a skirt in the lower part of the body allows for the container to be pushed out of the ground.
According to some users, plastic caisson Triton is the best way to protect expensive equipment for a well. The only disadvantage of a product made of polypropylene is the high price.
