Types of use for our cisterns
Our RTMO underground tanks are variably adaptable thanks to various modules
Variable
Speidel's indestructible underground tank can be used for more than just rainwater harvesting. Massive reinforcing ribs and the thickest walls of all PE underground tanks also make it the ideal storage tank for
1. Rainwater
2. Drinking water
3. Groundwater
4. Soakaways
5. Waste water
6. Retention
Rainwater
For garden irrigation of green areas, the underground tank can be used as a rainwater storage tank up to a large rainwater harvesting system

The principle of our cisterns simply explained and illustrated:
Drinking water
With the drinking water set, you can upgrade your underground tank to a drinking water storage tank
Drinking water tank
All Speidel underground tanks are made of high-quality, food-safe PE. This is confirmed by the KTW test certificate and the W 270 test. If you have clarified the official regulations, you can also use your underground tank as a drinking water storage tank without hesitation.
Groundwater
This revolutionary solution offers reliable groundwater protection at any water level:
Groundwater tank
With a module developed by us, all Speidel underground storage tanks can also be used in groundwater. The automatic water level control in the tank means that no pressure is exerted on the tank from outside. Compared to conventional systems, the groundwater module can be easily and simply installed in all Speidel underground storage tanks.
Retention
Retention cisterns only gradually discharge rainwater into the sewer system
Retention tank
A retention cistern often also brings financial benefits when calculating the sealed area and therefore the rainwater charge. In addition to pure retention, where all the rainwater is throttled and released into the sewer system, Speidel also offers the option of retaining part of the rainwater and using it for the garden and house.
Percolating juices

Don't make a mess with the manure
Leachate tank
The so-called LLDPE is resistant to almost all chemicals - and also to the components of leachate and its reaction and decomposition products. For this reason, our containers are particularly suitable for use as collection containers.
Waste water
The waste water module allows your underground storage tank to be used as a drainless collection pit
Waste water tank
The so-called LLDPE is resistant to almost all chemicals - and also to the components of leachate and its reaction and decomposition products. For this reason, our containers are particularly suitable for use as collection containers.
