3,300-Liter Underground Tank – A pre-assembled, ready-to-install solution for your garden and home
The GreenLife underground tank, with a capacity of 3,300 liters, is ideal for the underground storage and reuse of rainwater—for example, for garden irrigation, cleaning tasks, or household use. The compact cylindrical shape and the pre-assembled sliding dome with walk-on cover allow for flexible and safe installation—even on challenging terrain.
Depending on your requirements, your rainwater cistern comes with matching, factory-preassembled accessories. Choose between an inlet sediment trap, a tank-mounted filter with an inlet sediment trap, or the Biovitor—a biological and low-maintenance rainwater filter with an integrated inlet sediment trap.
Use our rainwater calculator to determine the optimal system size for effective rainwater harvesting.

Sustainability
The tank is made of durable and fully recyclable polyethylene (PE). Some of the material used comes from our own recycling program. The robust construction ensures reliable use for many years and helps conserve valuable resources.
The material used is environmentally friendly and chemically inert—it therefore has no effect on the quality of the stored medium. The production and recycling of the plastic tanks are relatively resource-efficient and support a responsible, future-oriented circular economy.
Notes
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 should be used.
Please follow the INSTALLATION INSTRUCTIONS: Before installing, connecting, and commissioning this product, read the instructions carefully and in their entirety, and observe all safety instructions. Failure to do so may void warranty and guarantee claims, particularly if a defect is attributable to improper installation.

It handles large flow rates with ease and is suitable for a wide range of applications, such as water supply and drainage tasks in clear water. The pump automatically regulates the water flow based on the user’s water demand. Examples of applications: Extraction of rainwater from rainwater systems, tanks, and cisternsUse of clear water inside or outside a buildingIrrigation of a lawn or gardenOperation of sprinklers or sprayers (on average, three sprinklers can be operated simultaneously)Draining or pumping water, for example from poolsDomestic water supply Operation / Performance: The pump is fully submersible and is immersed in the water. The maximum immersion depth is 12 meters. The pump automatically controls water delivery when the line to the consumer is open (faucet open). When the consumer is closed, the pump switches to standby mode. The pump is then in start/stop mode and maintains pressure in the line. When the consumer is opened again, the pump restarts and delivers water. The GAP X120 has a maximum flow rate of 100 liters per minute and a maximum head of 45 meters. This extremely high-pressure pump, with a maximum of 4.5 bar, enables effortless and effective irrigation. The power consumption (P1) is 1.15 kW. A built-in thermal motor protection prevents overload and ensures automatic restart after cooling down. Optionally, a pump base with side suction can be mounted for floating intake. This allows clean water to be drawn from below the water surface, not from the bottom. Quality: The use of stainless steel and high-quality plastic ensures a long service life. An integrated dry-run protection shuts off the pump in case of water shortage. A practical handle makes transporting the pump a breeze. With an IP 68 protection rating, the pump is dust- and waterproof. Conclusion: With the GAP X120 submersible pressure pump, you are purchasing a modern, automatic pump that switches on and off automatically according to water demand, features dry-run protection and thermal motor protection, and is suitable for both side and floating suction. Additional Features & Notes: Do not pump saltwater, wastewater, corrosive, highly flammable, or explosive substances (e.g., gasoline, kerosene, nitro thinner), oils such as heating oil and vegetable oils, or food! The water temperature must not exceed 35°C. An integrated, easy-to-clean stainless steel suction filter provides optimal protection against debris.Please note that (as described in the installation and operating instructions) this is a clear water pump that must only pump clean water—ideally pre-filtered with the Biovitor—to remain fully functional. You also have the option of using the pump base if the pump is placed on a surface rather than suspended (see installation instructions). Maintenance and Installation Instructions: If there is a risk of frost, drain the pump and store it in a frost-free location. Please follow the installation and operating instructions.

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
