Water pollution control

Avoiding hazards in a targeted manner

We provide assessment drawn up by experts pursuant to the Water Resources Act (WHG), § 62 Section 4 Nr. 7 (former § 19 i) for plants that handle water-polluting substances,. We also support you with:

  • Commissioning inspections
  • In service inspections
  • Decommissioning inspections
  • Advice relative to plant licensing 
  • Elaboration of Ordinance on Facilities Handling Substances Hazardous to Water (VAwS) concepts (e.g. in the framework of renovations)

Our task: Inspect, evaluate, and advise

The regulations concerning specialist companies and plants that handle water-polluting substances require that operators constantly monitor the leak-tightness and operability of the safety features of facilities where water-polluting substances are handled. The self-monitoring of plants requiring inspection should be supplemented with the supervision of an external VAwS expert.

Facilities subject to mandatory inspection

The inspection requirement for above-ground facilities usually depends on the quantities handled and/or the hazard rating of the plant. Underground facilities are generally subject to mandatory inspection. The hazard rating determines the quantities and water hazard class (WGK) of the materials found in the facility.

Therefore, underground fuel oil storage tanks (buried tanks), for example, are generally subject to mandatory inspection, while basement tanks are considered aboveground storage facility and only those over a certain size and/or the facility's hazard rating (the rating varies depending on the federal state) are subject to inspection.

Who needs to carry out inspection, and when?

As a rule, the plant operator must appoint a VAwS expert to carry out inspections pursuant to WHG, if a new plant was built, commissioned, significant changes were made to an existing facility and/or if the facility is being decommissioned. In addition, the inspection of underground storage tanks must be repeated every five years, and every 2.5 years in water protection areas. The operator will be required to correct any deficiencies found at the time of inspection immediately. The facility will be verified by the expert in case of considerable deficiencies, and the plant will be shut down if there are hazardous deficiencies.
