How to Choose the Optimal Size of an Underground Rainwater Tank?
Selecting the right size of an underground rainwater tank is a crucial step for anyone looking to efficiently utilize rainfall. A tank that is too large can be costly and underutilized, while one that is too small may not meet all irrigation and household needs.
How to Determine the Optimal Size?
Several key factors should be considered when choosing the tank size:
1. Roof Area
Rainwater is collected from the roof, so its size plays a crucial role. The larger the roof, the more water can be harvested during rainfall. If the roof is small, the water inflow will be limited, making an oversized tank unnecessary.
2. Garden and Property Size
If you plan to use rainwater for irrigation, the size of your lawn and garden is important. The larger the area, the more water you will need. In hot summer months, dry periods can last for weeks, making a sufficient water supply essential.
3. Other Uses for Rainwater
Besides irrigation, collected rainwater can also be used for:
-
toilet flushing,
-
car washing,
-
laundry.
Although water consumption for these purposes may not be high, frequent usage can make it significant. If you intend to use rainwater beyond irrigation, factor this into your tank size selection.
4. Climate in Your Region
Rainfall levels vary by region. If your area experiences infrequent or seasonal rainfall, a larger tank may be necessary to store enough water during rainy periods.

Choose a Tank with Extra Capacity
When selecting an underground tank, it’s better to opt for a slightly larger size. The cost increase with a bigger tank is minimal, but the extra water reserve can be invaluable during dry periods.
We offer underground tanks from Planus, Profi, and Czech Standard brands, with capacities ranging from 2 to 17 m³, allowing you to choose the ideal size for your needs. If necessary, multiple tanks can be connected to create a larger storage system.
