Frequently asked questions about separator cleaning
Here you will find answers to the most frequently asked questions about separator cleaning.
Yes, professional maintenance, emptying and inspection of separator systems is legally mandatory for companies in Austria.

Our full service ensures that you comply with all legal requirements. We professionally clean and empty the system, dispose of the contents in accordance with the regulations and maintain the technical components. As one of the few certified sealing testing companies, we also carry out periodic leak testing in accordance with ÖNORM B 2503.

Our goal is to provide you with a cost-effective solution that prevents expensive emergencies. Contact us for a clear and transparent offer that is tailored exactly to your needs.
The exact intervals depend on the type and size of your system as well as the use and are regulated by legal regulations. As part of our initial assessment, we create an individual maintenance plan for you that is tailored exactly to your system and regulatory requirements so that you no longer have to worry about anything.
Only a certified company such as derkanal.at can provide you with the legally secure documentation that you need for authorities. The certification is your guarantee of professional implementation in accordance with the applicable standards. With us, you are always on the safe side during checks.
If a need for renovation of the separator system or the supply and outlet pipes is discovered during the inspection, our service does not end.

This allows you to conveniently get analysis, maintenance and solution from a single source.
A neglected investment represents a significant risk. This can lead to blockages of the drainage pipes, severe odors and, in the worst case, the escape of environmentally harmful substances into the soil. This can result not only in high repair costs, but also in severe penalties from authorities.
