Rating of the best plastic and metal caissons for 2022

A serious problem for owners of cottages and private houses located far from the centralized infrastructure is providing them with water. For a successful solution, wells are equipped, pumping equipment is installed and pipes are brought to the facility. The result is a complete autonomous plumbing system. At the same time, the water source (well) must be reliably protected from the negative impact of adverse climatic factors and the ingress of groundwater with a special device - a caisson.

What it is

A caisson is a hollow waterproof chamber for isolating the wellhead, withdrawing the casing from it, placing pumping equipment and auxiliary elements.

Main functions:

• insulation and prevention of freezing of water, rupture of pipes and overload of pumping equipment;
• preventing the penetration of groundwater and wastewater into the water supply;
• prevention of corrosion damage to devices on the head;
• protection of equipment from rodents and insects;
• base for installation of pumps and cleaning filters;
• restriction of access of unauthorized persons to the well.

Device

The standard design is square, rectangular or cylindrical in the following form:

• at the bottom there is a hole for the well and connection with the pipe;
• at the top there is a neck with an insulated hatch;
• inside, a ladder is installed along the side wall to go down to service the well;
• inside the cavity there are pumps, pressure gauges, valves, pipelines, an expansion tank, filtration and reverse osmosis systems, pressure switches, as well as automation for controlling the operation of pumps.

Usually installed in a hole that is dug around the casing. The mouth is located below the freezing level at a depth of one to two meters, but above the water intake. The casing pipe goes inside by one or two meters, so the height of any caisson is more than two meters.

You can refuse to install a caisson, if the well is located next to the heated building. Then you can freely access any components of the system, but the noise is greatly increased.

Standard configurations

The section of the tank affects the geometry of the structure:

• square tank - width 90 - 150 cm;
• cylindrical tank - diameter 90 - 100 cm.

In order to accommodate a generator, a heater and other large automation, you need a tank with a width of at least 130 cm and a height of more than 200 cm.

As a rule, standard products are made with a height of 150 - 250 cm. The dimensions of the pit during installation should exceed the dimensions of the tank by 20 - 30 cm. In this case, the protruding parts of the neck should be taken into account: in width - 60 cm, in height - 50 cm.

A standard tank is enough to provide water to a private house. If necessary, you can find caissons with large dimensions.

Varieties

Depending on the material used, process tanks can be:

• plastic;
• metal;
• concrete with reinforced transverse metal rings;
• brick.

Plastic

They are made of polymer sheets or a solid cylinder in accordance with the requirements of GOST. The composition includes polyvinyl chloride (PVC), fiberglass, polyethylene, polypropylene. The walls of the tank are usually 1 - 4 cm thick. The stiffening ribs provide additional strength. Popular with users.

• easy access to equipment;
• durability while maintaining characteristics;
• resistance to corrosion and decomposition;
• long service life up to 30 years;
• complete tightness;
• good waterproofing;
• easy transportation and installation;
• excellent thermal insulation properties;
• relatively small price.

• the possibility of "floating" when the groundwater rises;
• the need for pouring a cement-sand cushion;
• vulnerability to deformation in case of soil compression;
• poor maintainability in case of cracking or breakdown.

How to properly equip a well with a plastic caisson:

metal

For production, stainless steel, aluminum or other metals with a thickness of 0.5-1.0 cm are used. It is usually made in a round shape, which has few joints. To improve the anti-corrosion properties, a primer must be applied from the inside, and bitumen from the outside.

• long service life up to 50 years;
• high strength;
• simple installation;
• good tightness and water tightness;
• stable position;
• maintainability;
• increased weight, preventing the "surfacing".

• susceptibility to corrosion;
• additional costs for waterproofing;
• low thermal conductivity, requiring insulation of the structure;
• the complexity of transportation and the need to use special equipment during installation;
• overcharge.

Reinforced concrete

Among users are considered the most unpopular.

Manufacturing options:

1. The construction is carried out by pouring concrete formwork with reinforcement installed in it. The shape of the filling well can be any.
2. Reinforced concrete rings are stacked on top of each other on a pre-prepared base. The connection of individual elements is carried out using a waterproofing compound. After reaching the desired height, a plate with a hatch is placed on top of the tank.

• long service life up to 100 years;
• high strength;
• low cost;
• non-susceptibility to ascent when the level of groundwater rises.

• the need for strict compliance with the GOST regulations;
• the possibility of subsidence due to the large weight;
• difficulties during transportation and installation;
• poor waterproofing with the development of corrosion of the reinforcing cage;
• insufficient tightness at the joints of reinforced concrete rings;
• poor thermal insulation with the need to insulate the concrete surface.

Video about the caisson of concrete rings:

brick

Usually, users make their own with their own hands. First, a concrete base is made, on which the walls are erected. A special cover with a hatch is placed on top. There are two options:

1. With backfill, a pit is excavated larger than the planned design of the caisson. After the erection of the walls and drying, the voids are covered with soil.
2. Without backfill, the dimensions of the pit correspond exactly to the dimensions of the tank. To prevent the formation of voids, the bricks are tightly pressed against the walls.

• durability;
• reliability;
• thermal conductivity without the need for additional insulation;
• profitability at a low price of bricks.

Criterias of choice

Experts advise what to look for in order to avoid mistakes when choosing:

1. Planned tank configuration.
2. The dimensions of the tank, taking into account the dimensions of the equipment installed for servicing the well.
3. Calculation of the level of soil freezing to determine the depth of the pit for the caisson.
4. Refinement of wall thickness depending on the intensity of soil heaving (determining parameter for a plastic tank).
5. Regularity of maintenance and repair work.
6. The need to install additional equipment, placing pockets for reinforcement.

The choice of material is based on the following rules:

1. When the well is in calm ground with low water levels and little soil movement, the best option is a plastic construction made of polyethylene with a high density and installed stiffeners.
2. Heavy reinforced concrete boxes are best installed on unstable ground, where there is a high level of groundwater. Plastic is less durable than metal. In addition, their repair will be much more expensive, unlike steel ones. In such cases, it is better to take stainless steel structures, although they will be more expensive at a price.

Sanitary standards

Due to the fact that the caisson, together with the well, is part of the adjacent residential area, the use of materials containing chemical elements harmful to the human body and the environment is prohibited.

The dimensions and location of the pit should ensure that repair or preventive measures are taken.

It should be noted that the upper chamber of the device with a sealed hatch must be located above ground level to prevent rainwater from entering.

Happy water supply. Take care of yourself and your loved ones!
