WISY makes it fit!
WISY rainwater storage tanks have a predefined construction height, which can, however, be changed by shortening the manhole or by attaching an extension pipe and thus adapted to the ground surface. The construction height can be shortened or extended by a maximum of 30 cm.Special note: When installing the rainwater storage tank in the ground, always ensure that there is no groundwater (e.g. also in the case of strata water on slopes).
All dimensions (in mm) are subject to manufacturing variations. Pipe and lead-through dimensions always refer to the bottom of the pipe.
The installation and operating instructions for this product are only provided in German and English. By purchasing this product, you agree to this.
NOTE: The extension of the dome shaft for the rainwater storage tank is only recommended up to a maximum of 30 cm.

Stable and tight - guaranteed!
The WISY rainwater storage tank is optimally shaped for the dissipation of vertical pressure loads. The rainwater storage tank is seamlessly manufactured in one piece and remains leak-proof in the long term. We give you a 20-year guaranteeon the durability of the environmentally friendly and durable polyethylene !
This stability makes the WISY cistern passable for cars. It can therefore be installed not only in the garden, but also under the garage driveway.
Even in adverse weather conditions, the anti-slip lid provides a safe surface. To ensure that no one can unintentionally endanger themselves, the lid of the rainwater storage tank can only be opened by using tools.
Easy handling on the construction site
Two stable lifting lugs facilitate handling on the construction site, for example with a small mini-excavator. The rainwater storage tank is underfilled in a load-bearing manner by filling gravel into the excavation pit. Pipe penetrations with inserted seals simplify installation.
The pressure water equalisation valve in the bottom of the cistern provides safety in case groundwater should collect outside. The wide dome shaft ensures easy access for inspection work.
