Specialist company according to the Water Resources Act

To protect water and the environment, work on systems for handling substances hazardous to water may only be carried out by specialist companies as defined by the Water Resources Act (WHG). Such facilities include commercial and industrial facilities designed for the storage, production or use of these substances. Due to the high risk to the environment, particularly high requirements are placed on WHG specialist companies.

A&W Maschinenbau GmbH is appropriately qualified as a specialist company and therefore authorized to manufacture containers and drip pans for this sector.

This results in a quality guarantee that you as a customer can always rely on.

Our ISO 9712-certified testing personnel are on hand to provide you with advice and assistance

in the field of weld seam testing.

NDT (non-destructive testing) is subject to a strict certification process in order to prevent personal injury and damage to property.

We can also offer VT2, PT2 or MT2 tests as an on-site service provider.
