Maintenance & repair: Professional care for your wastewater infrastructure

Your partner for scheduled maintenance
A functioning sewage infrastructure is essential for every property. Ensuring long-term functional reliability and at the same time keeping costs predictable is a central task for owners, property managers and facility managers.
This is exactly where we come in as your strategic partner. We offer you individual maintenance and repair concepts to solve problems before they arise. These include concrete, recurring measures that we tailor exactly to your property — whether as part of annual house sewer maintenance or to meet the requirements from the building book (ÖNORM B 1300).
Our services range from regular inspection of surface inlets to detailed inspection of the sewer system using CCTV Inspection to certified maintenance of grease, oil and gasoline separators. Together, we develop predictive planning that gives you the security of a perfectly maintained system.
Frequently asked questions about the maintenance & repair concept
Here you can find answers to the most frequently asked questions about maintenance & repair
A maintenance concept is a plan individually tailored to your property, which includes all necessary, recurring work on your sewage system. This includes regular cleanings (e.g. from surface inlets, traps, filters) exams (e.g. functional control of backflow protection) and professional inspection of the entire sewage system. This work is also often carried out within the framework of the requirements of Building book (ÖNORM B 1300) carried out.
Our care concepts are ideal for anyone who wants to plan for the long term and place responsibility for their wastewater infrastructure in professional hands. In particular, these include owners, property managers and facility managers who want to secure the value of their property and keep operating costs predictable and budgetable.
A one-time operation solves an acute problem. A maintenance concept, on the other hand, is a proactive partnership. We “manage” your system, take care of all necessary measures proactively and keep you up to date with complete documentation. This not only gives you security, but also saves considerable costs and effort in the long term.
The maintenance intervals depend on your system. As a guideline, we recommend annual house sewer maintenance and the inspection and cleaning of surface inlets twice a year.
Special systems have their own requirements: For separator systems (grease/oil/gasoline), we comply with clear legal requirements. For the backflow protection Quarterly to annual inspections are recommended, depending on the type of building.
As part of our initial assessment, we create an individual plan that is tailored exactly to the needs of your property.
Should a need for renovation be identified during an inspection, you benefit from our advantage as a full-service provider. We will inform you immediately and, upon request, create a transparent restructuring plan with a clear priority recommendation for the necessary measures. This gives you analysis, advice and solutions from a single source.
Since every care concept is individually tailored to the needs and circumstances of your property, there are no flat rates. The costs depend on factors such as the size of the plant, the condition of the pipes and the agreed scope of services. Our goal is to provide you with a predictable and budgetable solution that prevents expensive emergencies in the long term. After an initial assessment, you will receive a clear and transparent offer from us.
