Autarkic toilets
for your business

Toilets are a basic requirement for every restaurant. Whether it’s a beer garden, a farm winery or a restaurant by the lake, we all need a quiet place to go after a few drinks. However, our excursion destinations are often in the countryside and a sewer connection is not financially feasible. We have the ideal solution for you.

GOLDGRUBE® for business

The GOLDGRUBE® made of concrete can be integrated into buildings. In the case of a new building, integration should be considered from the very beginning. We will be happy to support you in finding your solution. Integration into existing buildings may also be possible, although this is of course somewhat more complex. Some important parameters can be found in the GOLDGRUBE® table below and  data sheets. They are in German only. 

Urine and faeces are collected separately without water or other additives. This means that high usage figures are possible with small collection volumes.

Overview: GOLDGRUBE® versions

The following table shows the different versions of the GOLDGRUBE®. All versions comply with the DIN 30762 standard. Some of them can be used in both private and public areas, but not all of them are suitable everywhere. The usage specifications are estimated values from experts. We will be happy to help you make the right choice. 

 

The concrete versions can all be integrated into a house and then have a round lid instead of a base plate. With a base plate, they are a “stand-alone solution”. The base plates or cover plates can have three different surface structures: concrete-rough, partially concreted or finished floor.

 

The data sheets provide further details on the different versions of the GOLDGRUBE®.

Self-sufficient toilet for the kindergarten

Nature and forest kindergartens also need a toilet solution. Due to their distance from the nearest village, a self-sufficient toilet is necessary.

Together with LivingCircles, we were able to equip two kindergartens in the Swabian Alb with our system in 2023. 

Autarkic toilet at the grill hut

Excursion destinations in the mountains, whether with or without wine, often have the problem that a connection to the sewage system is not possible or involves very high investment costs.

We were able to equip this barbecue hut in the Upper Rhine Graben with one of our toilet facilities in 2019. This was a low-investment solution for the municipality. For the tenants of the hut celebrating, it was a pleasant way to make things easier.

Self-sufficient toilet
at the climbing park

Outdoor sports are in vogue. Whether bouldering, climbing or hiking, we enjoy spending time in nature. However, many places lack the appropriate facilities to provide the necessary relief.

The climbing park in Rothenburg ob der Tauber chose us in 2011. Since then, five people have been able to go to the toilet there at the same time.
