Building, modifying or demolishing property drainage systems may only be carried out by recognized specialist companies in accordance with 13b HmbAbwG.
With the division into different implementation areas, the specialist companies were given the opportunity to only have those in which they actually work certified. If a specialist company is certified for certain areas of execution, it may only carry out the work associated with it.
In order to be certified, the specialist company must submit an application to one of the approved certification organizations. The authority itself does not issue any certificates. The certification organizations provide information about the requirements for certification and the associated costs.
