Underground containers

Underground plastic tanks are used to store drinking and process water, fuel and oil products, acids and alkalis, and to collect wastewater. Applications include construction, where underground tanks are used to equip water supply and sewage systems. The thickness and type of plastic (impact-resistant, resistant to high temperatures), size and shape determine the price of a tank.

Underground plastic tanks: advantages

Light weight is one of the main advantages of plastic products. Its low weight makes it easier to transport and install the structure. The parameters that make plastic tanks better than their metal counterparts include low cost and corrosion resistance. Unlike metal tanks, an underground plastic tank is not subject to rotting in conditions of constant contact with wet soil. Other advantages:

• Maintainability. Plastic tanks can be repaired with complete restoration of tightness.
• Durability. The service life exceeds 60 years.
• Chemical inertness. The tank material does not interact with the stored contents.
• Easy maintenance. No need for regular treatment with anti-corrosion compounds and painting.
• Versatility. Plastic tanks are suitable for storing drinking water and technical liquids.
• Cost-effectiveness. The purchase and installation of a plastic tank does not require significant financial investments.
• Resistance to temperature extremes. The operating temperature range is from -30 to +50°C.
• There is no need for a caisson during installation.

At transport and construction companies that use specialised equipment, a plastic tank is installed in the ground to store diesel fuel and fuels and lubricants. Plastic tanks are installed underground for the construction of septic tanks, drainage systems and wastewater storage tanks. A supply of process water is necessary for irrigation on farms and private households, firefighting and maintenance of industrial processes. Process water stored in underground tanks is used for cleaning the territory, washing facades and vehicles.
The water tank in the ground is invisible to others. The tank does not take up space on the territory adjacent to the building or adjacent to the industrial facility, which allows you to use every metre rationally. The underground installation improves fire safety, which is important when storing flammable liquids and substances. Plastic structures made by rotational moulding are free of welds, which ensures tightness and increased strength.

Installation features

For underground installation, a horizontal rectangular or cylindrical tank is optimally suited. A horizontal underground plastic tank has an increased support area. No need to dig a deep hole for installation. To install the tank in the ground, it is necessary to involve qualified specialists who will take into account the type of soil, the presence and level of groundwater, and other factors. General conditions for placing an underground tank:

• distance to trees at least 3 metres;
• distance to carriageways at least 5 metres;
• distance to water bodies at least 10 metres.

The depth of the tank is calculated depending on the degree of soil freezing. Septic tanks should be installed in accordance with building and sanitary standards. It is necessary to provide for the possibility of access to the septic tank for special machines that pump out wastewater. For installation in peat or water-saturated soil (sand, sandy loam), it is necessary to equip the formwork. If the groundwater source is located close to the tank, a drainage system is installed to reduce the pressure on the tank walls.
