6,500-Liter Underground Tank – Large-Capacity Cistern for Underground Rainwater Storage More storage capacity for efficient rainwater harvesting: The GreenLife underground tank, with a capacity of 6,500 liters, is a robust and durable solution for underground rainwater storage in homes and gardens. Thanks to its large tank volume, the cistern is particularly suitable for larger properties, intensive garden irrigation, or applications where large quantities of non-potable water are regularly required. Rainwater can be used in a variety of ways, for example for garden irrigation, cleaning tasks, or household applications where drinking water is not required. The underground tank comes ready for installation and can be combined with the appropriate accessories as needed. Choose between versions without accessories, with an inlet stabilizer, with a tank-mounted filter, or with Biovitor—a biological and low-maintenance rainwater filter with integrated inlet stabilization. Use our rainwater calculator to determine the appropriate system size for effective rainwater harvesting.

Delivery within mainland Germany is free of charge, delivered curbside. Please note our information regarding the delivery process. Sustainability, Materials, and QualityThe tank is made of durable polyethylene. The material is corrosion-resistant, durable, and very well suited for underground rainwater storage. Thanks to its robust construction, the underground tank is designed for long-term use and supports resource-conserving rainwater harvesting for many years.The material used is chemically inert and has no effect on the quality of the stored water. At the end of its service life, the product is fully recyclable and can thus be returned to the recycling cycle. Notes For round tanks, the excavation pit is generally dug deeper rather than wider. If groundwater or perched water is present, appropriate protective measures are required. Please refer to the respective installation instructions for this. Alternatively, the use of a flat tank may be advisable if soil conditions permit. Read the installation instructions carefully and in their entirety before installation, connection, and commissioning, and observe all safety instructions. This is the only way to ensure safe and proper operation. Improper installation or failure to follow the instructions may void warranty and guarantee claims, particularly if a defect is attributable to faulty installation.
