The best way to water large garden areas is to install an underground tank. Using our RTMO as an example, we will show you what distinguishes our underground tanks.
Made in one piece by rotary process
Thick-walled, robust and dimensionally stable
Massive reinforcing ribs and the thickest walls of all PE rain tanks make this cistern extremely robust and dimensionally stable.
The underground tank with walk-on lid is accompanied by a dome basket filter for installation in the tank dome.
Divertron garden pump and garden extraction kit
Overflow siphon serves as an odor trap and drains off the suspended solids
Large, oval manhole dome for convenient descent even with filter technology installed
Two crane eyes and four carrying handles for easy transport and handling of the tank
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.
It's all about the technique
Size alone does not matter - this also applies to our tanks. They offer enough space inside and thus installations of different technologies can be flexibly designed, no matter which combination you choose.
