2,100-Liter Underground Tank – Compact Tank for Rainwater Harvesting
The GreenLife underground tank, with a capacity of 2,100 liters, is ideal for the underground storage and use of rainwater—for example, for garden irrigation, household use, or cleaning tasks. Thanks to its compact, cylindrical design, the tank can be installed in a particularly space-saving manner and is ideal for smaller properties, gardens, or tight installation spaces.
Its relatively low weight makes transport and installation easy to handle. At the same time, the sturdy construction ensures high load-bearing capacity and long-lasting use.
The tank is delivered ready for connection—including an integrated dome, lid, and pre-assembled connection gaskets. Additional connection points allow for flexible expansion or later retrofitting.
Depending on requirements, various configuration options are available—from the basic version without accessories to the model with a Biovitor rainwater filter.

Material, Sustainability & Quality
The tank is made of high-quality polyethylene (PE), is recyclable, and contains a proportion of recycled plastic. The material is free of harmful substances, chemically inert, and has no effect on the quality of the stored water.
The rotational molding process creates a seamless, stress-free tank body with high dimensional stability and permanent leak-tightness. The durable construction enables sustainable and resource-efficient use for many years to come.
