However, risks arise in many drinking water installations: stagnation, corrosion, deposits, or biofilms promote the growth of Legionella and other bacteria.
If a limit value according to the Drinking Water Ordinance is exceeded, immediate action is required—to protect people and facilities.

We ensure sustainable drinking water hygiene through targeted cleaning and disinfection of
✔ Drinking water pipes
✔ Fittings
✔ Taps
✔ Entire systems

Our processes eliminate Legionella, Pseudomonas, and other microorganisms effectively and permanently – naturally in compliance with the law and documented.

Drinking water needs a system

Clean drinking water is not a matter of chance - it requires a functioning overall system consisting of technology, analysis, special chemical products, and monitoring.
Only when all components work together can drinking water quality remain hygienic, legally compliant, and economically stable in the long term.

In concrete terms, this means:

• It is not individual measures (e.g., flushing) that ensure quality,
  but the coordinated interaction of all system components.
  
  
• Materials, hydraulics, temperature control, dosing, and monitoring must be perfectly coordinated.
  
  
• Systematic planning, control, and documentation form the basis for sustainable drinking water hygiene.
  
  
• Dr. Hartmann Chemietechnik offers exactly this system:
  From drinking water analysis to cleaning and disinfection to digital monitoring with DHC W|C|S® – everything from a single source, in accordance with TrinkwV, DVGW W 551, and VDI 6023.

Your benefits:

Health protection, legal certainty, longevity of the systems, and confidence in your water quality.
