Differences between the 3,000 L complete sets
Garden irrigation or household and garden

The WISY 3000 litre cistern complete sets are available in several versions to suit different requirements. All variants are based on a 3000-litre cistern with coordinated filter and pump technology, but differ significantly in terms of functionality.

For garden irrigation
with suitable equipment

The 3000 litre complete cistern sets for garden irrigation differ only in the material and design of the cistern. Depending on the installation situation, you can choose from robust concrete cisterns, lightweight plastic cisterns or flat tank versions.

The compact size is particularly suitable for smaller gardens with moderate water consumption and makes the 3000 litre water tank in the garden an ideal solution. The stored rainwater is fed directly to the hose, sprinkler or drip irrigation system via the integrated pump - convenient, reliable and resource-saving.

The integrated Beta garden pump and the water socket are always the same for all 3000 litre complete cistern sets for garden irrigation. However, you can select the lid and the filter package with inlet stabiliser and connecting parts individually on the product page.

For garden and domestic use
Safe and standardised refilling

All 3000 litre complete sets for rainwater harvesting in the home and garden are equipped with a fine vortex filter and a rainwater unit. The appropriate filter model is selected based on the connected roof area to ensure reliable pre-filtration and permanently good water quality.

There are several variants to choose from for the rainwater unit. The ideal design depends primarily on the distance between the cistern and the building. The rainwater unit conveys the stored water via its own pipe network to typical consumption points such as toilet flushing, washing machine or cleaning connections.

The rainwater unit 's automatic drinking water backfeed ensures that the supply remains uninterrupted even when the cistern is low. All systems work in accordance with standards with a strict separation between drinking water and rainwater in accordance with DIN EN 1717 - for maximum safety and long-term reliable operation.

Is a rainwater tank
with 3000 litres sufficient?

Whether a 3000 litre rainwater tank set is sufficient depends primarily on the size of the roof area, the regional rainfall and the planned consumption. For smaller gardens and households with moderate water requirements, a storage tank of this size offers a compact and efficient solution for utilising rainwater over many weeks.

A 3000 litre rainwater tank set is particularly suitable if the irrigation areas are manageable or household consumption remains limited. Thanks to the coordinated technology of the complete sets, the available rainwater can be utilised very efficiently.

If larger lawns are to be watered or additional rainwater is used in the household, a larger storage tank can be useful. Alternatively, several cisterns can be connected together to flexibly increase the total volume.

Sample calculation
for a 3000 litre complete set

A typical roof area of 80 to 100 m² can provide around 60,000 to 80,000 litres of rainwater per year, depending on the regional rainfall. A 3000 litre rainwater cistern is therefore regularly filled and provides sufficient storage volume for watering smaller gardens or for individual household consumption points.

A complete filling is usually sufficient for around three weeks - whether for the needs of a two-person household or for economical watering in the garden. A 3000 litre storage tank therefore offers sufficient reserves to bridge a phase without rainfall and to use rainwater efficiently.

Concrete or plastic
Which material suits your project?

The 3000 litre complete sets are available in various cistern designs, which differ primarily in the material used. Concrete cisterns offer particularly high stability and are ideal for demanding installation conditions or increased groundwater pressure. They are considered to be extremely durable and buoyancy-proof - a robust solution for many decades.

Plastic versions are significantly lighter and are easier to transport and move. A 3000 litre plastic cistern set is particularly suitable for quick installation or when only limited working space is available. The smooth inner surfaces mean that hardly any deposits form, which makes cleaning easier and supports the water quality in the long term.

If the installation depth is shallow, a 3000 litre flat tank complete set is also an option. This shallow design reduces the amount of excavation required and is ideal if above-ground obstacles or structural restrictions need to be taken into account.

All variants are suitable for underground installation, frost-proof and designed for a long service life. Which design is the right one depends on the structural conditions, the accessibility of the site and the individual requirements.

Advantages of the 3000 litre
rainwater cistern complete sets

A 3000 litre cistern set for garden or household use offers a compact and space-saving solution for anyone who wants to use rainwater efficiently. The right combination of storage tank, filter and pump technology creates a system that works reliably in the long term and requires minimal planning effort.

All components are selected to harmonise perfectly in terms of function and performance. This reduces the risk of planning errors, saves installation time and ensures that the 3000 litre rainwater tank set guarantees a stable and reliable supply under a wide range of conditions.

Thanks to the modular design, the systems can be flexibly expanded or supplemented with additional accessories. This means that each complete set can be customised precisely to the individual requirements of the home and garden.

Collect rainwater
with sets from WISY

The 3000 litre complete cistern sets from WISY are designed to collect, store and utilise rainwater as efficiently as possible. A fine vortex filter filters the water on its way from the roof to the cistern, preventing impurities from entering the storage tank in the first place.

In the cistern itself, the water remains largely free of swirling sediment thanks to a calmed inlet and suitable extraction. The collected rainwater is then conveniently available for garden irrigation or domestic applications via the integrated pump technology.

Thanks to the harmonised combination of filter, storage tank and pump, the entire path of the rainwater - from the roof surface to the extraction point - is mapped in a technically sensible way. In this way, natural precipitation can be utilised reliably and in a resource-saving manner in everyday life.
