RTMO

Rainwater cistern - the PE underground storage tank from Speidel

For garden irrigation of green areas, the underground tank is ideal as a rainwater storage tank through to a large rainwater utilisation system.

Using our RTMO as an example, we will show you what characterises our PE plastic cisterns.

Think carefully about what you bury in the garden

The indestructible underground tank from Speidel is made of high-quality PE plastic and is Made in Germany. Massive reinforcing ribs and the thickest walls of all PE rain tanks make it so robust that we can ensure the proverbial Speidel quality for 25 years.
