Technical Support Following Fires and Other Incidents
After a fire, businesses, government agencies, and emergency responders often face the next challenge: the safe treatment of contaminated firefighting water. During firefighting operations, firefighting water can absorb pollutants, chemicals, soot particles, oils, heavy metals, or other hazardous substances. Depending on the type and concentration of the substances it contains, this can pose risks to soil and water.
Prompt and professional assessment and treatment may therefore be necessary. Depending on the location, substance composition, and facility approval, the ZIMMERMANN Group offers services for the collection, transport, temporary storage, treatment, and treatment of contaminated firefighting water. The Group’s own logistics, treatment facilities, temporary storage sites, and the emergency and claims management enable a response tailored to the specific incident.


Why Firefighting Water Must Be Disposed of Properly
After a fire, firefighting water often has properties that are completely different from those of ordinary wastewater. Depending on the materials involved, firefighting water may contain numerous pollutants.
These include, for example:
- Chemicals
- Solvent
- Oils and Fuels
- Heavy metals
- soot particles
- Production backlogs
- Varnishes and Paints
- Cleaning products
- contaminated solid particles
If these substances are released into the environment in an uncontrolled manner, they can cause damage to water bodies, soil, and public infrastructure, depending on their type, quantity, and concentration. The appropriate treatment and disposal method must therefore be determined based on the specific nature of the contamination and the relevant legal requirements.
