Compact 500 litre mini underground water tank for efficient rainwater harvesting

500 litre mini underground water tank is the ideal solution for storing rainwater underground in small gardens or on plots with limited space. The tank is made of black, food-safe PE plastic, which is moulded in one piece and has no weld seams. This design ensures exceptional stability and durability of the tank.

With a diameter of 120 cm and a height of 100 cm, the tank can be easily installed underground. The manhole dome with a diameter of 55 cm and a 48 cm opening ensures easy access. The green tank lid can be screwed on, is double-walled insulated and is fitted with a stainless steel child safety lock for added safety.

Thanks to its compact design, this tank is ideal for rainwater utilisation in domestic gardens. It is installed inconspicuously below ground and can store up to 500 litres of rainwater, which can be used for irrigation, garden maintenance or other purposes.

The mini underground water tank is a sustainable and space-saving solution for anyone who wants to utilise rainwater and at the same time store water in an environmentally friendly way.
