Water Tanks for Irrigation: What Is the Best Way to Store Water?

Agriculture is one of humanity’s oldest and most important activities. Over time, techniques, tools, and technologies have evolved, but water, as the primary source of life for plants, remains unchanged. This makes water tanks essential and perpetually relevant in agriculture. Modern farmers cannot rely solely on rainfall to meet their needs.

Water Tanks: From Small Gardens to Large Agro-Industrial Complexes

Meeting the water storage and irrigation needs of a small backyard garden is relatively simple. However, managing water for large-scale agricultural operations is much more complex. For example, a water tank for drip irrigation in a greenhouse might hold 200–400 liters. Meanwhile, to irrigate extensive farmland, reservoirs with a capacity of 25–50 cubic meters, or even larger, may be required.

For smaller needs, the range of options is broad – from plastic barrels purchased at a hardware store to homemade metal containers. In larger agro-industrial complexes, old automotive or railway tanks are still commonly used. Traditional metal tanks have certain advantages, such as their ability to heat the stored water effectively. However, they also come with significant drawbacks, the most critical being corrosion, which gradually destroys the container and alters the water’s chemical composition.

Irrigation Water: Quality Determined by Storage Conditions

To ensure proper irrigation, it is essential to follow a few basic rules:

  • Do not use tap water for irrigation as it is often chlorinated and harmful to plants.
  • Avoid watering plants with cold water, which can cause temperature shock and potentially kill them.

Water should be stored in closed tanks to prevent debris, insects, and sunlight from entering. Direct sunlight can promote algae growth, while the water should ideally be warmed to 15–20°C for optimal irrigation and to maintain its chemical composition.

The quality of irrigation water directly affects plant growth and their ability to absorb nutrients. Moreover, modern agricultural practices often involve fertigation (the addition of fertilizers to irrigation water). This requires a dedicated water tank that can handle not only water but also critical elements such as nitrogen, potassium, and phosphorus. Such tanks must maintain the chemical integrity of the solution over time.

Advantages of Flexible Water Tanks

Finding the right water tank that meets all these requirements is not as easy as it may seem. A universal flexible tank Flexsol for irrigation and fertigation offers a versatile solution that meets all the criteria. These mobile tanks, made from technical fabric, resemble a hot water bottle in shape and take up minimal space when folded.

Key Advantages of Flexible Water Tanks:

  1. Chemical neutrality to the contents of the tank.
  2. Excellent thermal conductivity, ensuring that the water is warmed appropriately.
  3. Durability, resistant to UV rays, corrosion, and climatic, chemical, or seismic impacts.
  4. Compactness when stored.
  5. Quick deployment and readiness for use without the need for extensive preparation.
  6. Lower cost compared to traditional metal or plastic counterparts.

Flexible water tanks have been used in Western Europe for over 50 years. In Ukraine, they are gaining recognition among farmers, though they are still considered a relatively new solution.

Where to Buy a Water Tank?

You can purchase water tanks directly from manufacturers, avoiding commissions and additional charges.
