The robust GreenLife underground tank with a 2,200-liter capacity is ideal for the underground storage and use of rainwater—for example, for garden irrigation, cleaning tasks, or domestic water use. Thanks to its compact, cylindrical design, the tank can be installed in a particularly space-saving manner and is ideal for small properties, gardens, or tight installation spaces.
The factory-preassembled sliding dome with a walk-on cover enables flexible and safe installation. The tank is delivered ready for connection and can be selected with various equipment options depending on requirements—from the basic version to the variant with a Biovitor rainwater filter.
Use our rainwater calculator to easily determine the right system size for efficient rainwater harvesting.

Material, Sustainability & Quality
The tank is made of high-quality polyethylene (PE), is recyclable, and contains a proportion of recycled plastic. The material is environmentally friendly, 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.
Notes
Please follow the installation instructions and read all notes carefully and in full before installation, connection, and commissioning. Improper installation or failure to follow the instructions may void warranty and guarantee claims, particularly if the defect is attributable to faulty installation.
For round tanks, dig deeper rather than wider. If groundwater or stratum water is present, appropriate precautions must be taken (see installation instructions) or, alternatively, flat tanks must be used.

GAP X80 Rainwater Tank Pump – Your Automatic Submersible Pump with Dry-Run Protection The GreenLife GAP X80 automatic submersible pump is a high-quality, reliable, and powerful device designed specifically for extracting clear water from rain barrels, rainwater systems, flat tanks, and cisterns. The pump can be used, among other things, for emptying rainwater storage tanks as well as for watering gardens and green spaces. The pump is fully submersible and is immersed in the water. Water delivery is automatically controlled when the line to the consumer is opened. When the consumer is closed, the pump switches to standby mode. The pump then enters start/stop mode and maintains pressure in the line. Included as an accessory is a telescopic tube with a bracket (hose kink protection) to position the pump at the edge of the tank. The convenient shut-off valve with quick-connect coupling allows you to easily draw water from the rainwater barrel. If the pump is located in a tank or cistern, a water connection box or garden tap can be operated directly via the ¾-inch connection.

Vent and air release valves for safe pressure equalization & reliable emergency drainage The vent and air release valve with DN 100 emergency overflow ensures reliable air equalization in tanks, pipes, and soakaway systems and effectively protects the system against overpressure or underpressure. If the maximum water level is exceeded, for example during heavy rain, the component also acts as an emergency overflow for safe drainage. The vent is typically installed at the end of an infiltration system and is usually discreetly located outdoors, e.g., in a hedge or flower bed. To ensure that (rain)water can flow smoothly into the system, a controlled air outlet must be provided elsewhere. For this purpose, a DN 100 KG pipe is installed behind the system, which safely guides the air to the surface. The vent is the terminus of this line and is designed to reliably prevent the entry of animals. Product Features & Benefits at a Glance Pressure equalization during water withdrawal or supply – prevents damage caused by overpressure or underpressure Automatic venting and de-airing – ensures trouble-free system operation Integrated emergency overflow – protects against overfilling during heavy rain Standard DN 100 connection – compatible with common KG pipe systems Lightweight & durable – approx. 350 g, made of robust polypropylene Made in Germany – manufactured to high quality standards and DIN EN ISO 14001:2015 Typical applications Rainwater storage tanks & infiltration systems – for ventilation and emergency drainage Wastewater collection pits & infiltration systems in wastewater treatment plants – for pressure equalization and operational reliability Sustainability The product is made of durable, single-grade, and fully recyclable polypropylene. The material is long-lasting, free of harmful substances, environmentally friendly, and chemically inert – it has no impact on the environment. The production and recycling of this plastic are resource-efficient. Responsible use in line with the circular economy is a central component of our sustainable practices. Notes The vent should be inspected once or twice a year to ensure consistently reliable operation.
DetailsSmooth inflow of rainwater into the rainwater storage tank. Fine particles of dirt slowly settle to the bottom and form a sediment layer, which has been proven to have a positive effect on the stored rainwater. Turbulence in the sediment layer is prevented, while oxygen is simultaneously supplied to the stored water. Technical DataMaterial: PolyethyleneConnection: DN 100 (Ø110)Height: 296 mmDiameter: 288 mm
