Garden system AKTION with 4200 l flat tank

Product information " Garden system AKTION with 4200 l flat tank"

Rainwater harvesting system for the garden: “AKTION” garden system with a 4,200-liter rainwater tank 

Easy-to-install complete system for garden irrigation 

Our “AKTION” rainwater harvesting system is an all-inclusive package featuring a practical flat tank for easy installation underground. The high-quality rainwater tank is made of eco-friendly polyethylene (PE) and is 100% recyclable. 
The ready-to-connect complete set includes everything from the rainwater cistern to the submersible pressure pump—all the small and large components you need for rainwater harvesting in your garden. Collect precious rainwater in the underground rainwater tank during wetter times and use it for garden irrigation during drier periods.

How does garden irrigation work with the "AKTION" garden system? 

Rainwater flows from the roof through the gutter grate (which acts as a pre-filter), then down the downspout and through the inlet surge arrester into the flat tank. The automatic submersible pressure pump located in the tank is connected to the water connection box via a hose that runs through a conduit. When the valve in the box is opened, the pump starts automatically. Closing the valve causes the submersible pressure pump to shut off on its own. You can install the water connection box wherever is convenient for you. 
When the cistern is full, the rainwater drains off via the overflow siphon. The barrier integrated here prevents small animals from entering. If there is a risk of frost, the pump must be disconnected from the power supply and the valve on the water connection box must remain open. 
You can find all further information under the DOWNLOADS tab and in the DOWNLOAD AREA.


Who is the "AKTION" irrigation system suitable for? 

The complete set is suitable, on the one hand, for anyone who wants to keep the effort involved in installing their tank to a minimum. On the other hand, it is suitable for those who value the convenience of water withdrawal at a water connection box. 

Is the "AKTION" garden system drive-over? 

The flat tank is not drive-over in this form. However, upon request, all flat tanks can be retrofitted with our kit for car drive-over capability. The resulting wheel load is 600 kg per wheel—sufficient for standard cars and small vans. In this case, the cistern must have a soil cover of at least 60 centimeters. 

Where does the water from the overflow go when the tank is full? 

The excess rainwater can be discharged into the sewer system. However, this may incur fees. Additionally, the water does not return to the groundwater in a natural way when discharged this way. 
The most environmentally friendly option is (trough) infiltration through the soil surface. However, this is often not structurally feasible. 
With our infiltration elements, we offer a good way to allow overflowing water to infiltrate: Using infiltration cubes, infiltration blocks, or infiltration shafts, rainwater is guided through the soil back into the groundwater. 

Do I need a rainwater filter? 

This rainwater harvesting system generally does not require an additional rainwater filter. The gutter screen already provides sufficient coarse filtration. However, if you place particular importance on extra-clean water in your garden, you can install our fully biological Biovitor rainwater filter for flat tanks in all flat tanks. 

Installation and Maintenance Instructions for the 4,200-Liter Flat Tank

Our customer service team is available to provide expert assistance. Please contact service@greenlife.de or our customer service at 0385 77 337 72 (weekdays 8 a.m.–4 p.m.). 


The entire system must be checked regularly for leaks, cleanliness, and stability. 

Maintenance of the entire system should be performed at intervals of approximately 5 years—every 10 years if a GreenLife Biovitor is used in accordance with the instructions. During this process, the system components must be cleaned and checked for proper function. 

Maintenance should be performed as follows:
  • Empty the tank completely
  • Remove solid residues with a soft spatula
  • Clean surfaces and internal components with water
  • Completely remove dirt from the tank
  • Check that all internal components are securely fastened

Delivery Process

Once you place your order, you will first receive an email with the order confirmation. One to two business days later, we will send you a digital order confirmation, in which you will find the estimated delivery week in the top right corner—unless you have ordered with prepayment: In that case, the estimated delivery date is approximately 10 business days (Mon.–Fri.) after receipt of payment. 
One of our freight carriers will typically contact you 1–2 business days before the actual delivery date—for this, we need your (ideally mobile) phone number.
If no one will be on site for delivery, please provide us with a drop-off authorization (in the comment field during the ordering process). Double-tank systems are excluded from this.

The tank is unloaded “curbside”—the recipient must provide unloading assistance (in the form of 1–2 people). The recipient is responsible for transporting the tank the rest of the way to its final location.** 
It may happen that our goods are delivered by a large truck (7.5–40-ton). Therefore, please inform us during the ordering process (comment field in the “Complete Order” step) about the conditions at the delivery address or any access restrictions; this is necessary for planning the delivery and cannot be taken into account on the delivery day itself! If you fail to do so, we will have to pass on any resulting additional costs to you! 
If your delivery address is inaccessible even to a light truck, you must pick up the tank yourself (from the last accessible road). 
Please also note that there are no deliveries on weekends or holidays. 

* Accessories (e.g., dome + cover) may be included in a separate package/pallet, but may also be placed directly inside the container/tank. If you order accessories or covers separately, they are generally shipped separately via parcel service. 
** Please refer to the product description for the weight of your tank. You will need assistance from personnel or machinery to transport your tank.

ATTENTION: Should delays occur during delivery, any additional costs incurred (rental of equipment) cannot be claimed from us/the seller.

GreenLife's gutter guard is the perfect filter for rainwater. Whether the water is collected in cisterns or rain barrels, plant debris such as leaves and twigs can reduce water quality. It is therefore always recommended to pre-filter rainwater as thoroughly as possible, starting right at the gutter. Leaf guards filter rainwater Especially in the fall, when trees shed their leaves, it can be very frustrating when heavy rain causes leaves to enter the downspout and thus the rainwater tank. Not only does the quality of the collected water suffer from the debris, but it can also quickly clog the downspout. Cleaning often involves a lot of effort. Therefore, always use a leaf guard. Potential problems without a leaf guard Clogged downspouts Blockages in water hoses or showerheads Discoloration of the water Reduced water quality Staining of the gutter Breeding ground for pests With this simple leaf guard from GreenLife, such problems are a thing of the past. Assembly is incredibly easy, and cleaning usually requires nothing more than a hand brush. The gutter guard also provides reliable protection against birds. They can no longer nest in the gutter and must find other places to settle. Can I filter the rainwater even further? Yes, because the gutter guard is only a pre-filter. Depending on the type of your rainwater harvesting system, you can also use downspout filters, built-in filters, or tank-mounted filters. In addition to these mechanical filters, the patented Biovitoren for cisterns can also be used. These are biological filters that require very little maintenance. Installation of the gutter protection grid Installing the gutter guard is very straightforward. Each package contains segments for approximately 3.00 meters, which simply slot together. Depending on the width of the gutter, the guard can be folded. It fits any standard gutter size.https://www.youtube.com/watch?v=IVG8j1yDEMM
