Rain barrels from WISY: sustainability meets functionality
Rain barrels are an environmentally friendly way to utilise rainwater efficiently and reduce the consumption of valuable drinking water. With minimal space requirements and simple installation, they offer an ideal solution for garden irrigation and at the same time contribute to the protection of resources.

Which rain barrel do I need?
For occasional water requirements, we recommend storing rainwater in a frost-proof rain barrel with a lid. It should be impermeable to light, made of UV-resistant material and have a solid lid. This prevents algae growth and you can enjoy a safe rain barrel with lid for a long time in which no mosquito larvae can multiply.

The perfect location for your rain barrel
To get the most out of your rain barrel, the location is crucial:
- Stable base: Place the barrel on a level, solid surface to prevent it from tipping over. Filled rain barrels can weigh up to one tonne.
- Proximity to the downpipe: Position the rain barrel directly next to a downpipe so that the water is collected effectively.
- Shady location: A shady location is ideal for rain barrels. Also choose an opaque material that keeps out sunlight and thus extends the service life of the rain barrel.
Position the water butt so that a watering can fits comfortably underneath. A platform can be placed under the barrel for this purpose, again ensuring sufficient stability. Alternatively, the outlet tap in the water butt can be mounted slightly higher so that the lower area always remains filled with water. This provides additional stability in strong winds and sediment remains in the tank without getting into the watering can.

Care and protection
To ensure that your rain barrel lasts a long time, follow these tips:
- UV protection: A rain barrel made of UV-resistant plastic remains durable and stable even when exposed to direct sunlight.
- Frost-proof storage: WISY offers frost-proof rain barrels that remain stable even when filled and frozen in winter. All other rain barrels should be completely emptied in winter to prevent damage from freezing water.
- Protect with a lid: A lid prevents contamination from leaves or insects and provides additional safety for children and animals. WISY rain barrels are designed to provide a secure closure to minimise risks.
Modern designs and colours
For many, the aesthetics of the garden are decisive. WISY offers rain barrels in different colours and shapes:
- Popular colours: Anthracite, stone grey or a dark green.
- Decorative rainwater barrels: Models in the style of antique columns, in a minimalist design or simply plain and functional.
- Practical features: Rain barrels with lids or integrated outlet taps that make it easier to draw water.
High filling capacity with minimum space requirement
Whether small or large gardens: there is a suitable rain barrel for every need.
- 500 litre rain barrel: Ideal for medium-sized gardens.
- Rain barrel 1000 litres: Perfect for large plots or vegetable patches.
- Narrow rain barrel: For limited space, e.g. on house walls or in narrow aisles.
Thanks to innovative designs such as above-ground rainwater tanks, a lot of water can be stored in a small space.
Connection options at a glance
Connecting a rain barrel to the downpipe is particularly simple and efficient with the specially developed WISY filter collectors. The filter collector directs clean water into the rain barrel and has a self-cleaning filter function that automatically flushes coarse and fine dirt particles such as leaves and moss into the downpipe. This keeps the filter insert low-maintenance and efficient.
The watering can can be quickly filled at the water butt with tap - without any electricity!
Expansion of the storage capacity:
Several rainwater barrels can be connected using rainwater barrel connection sets to increase the storage volume. WISY offers suitable filter variants for all standard downpipe diameters. Matching housings are available in stainless steel, copper or plastic, which impress with their durability and frost resistance.

Why collect rainwater?
