1What Accumulates in Water Tanks?
Over time, mud, rust, algae, and biofilm layers form at the tank bottom. This environment is ideal for breeding Legionella, E.coli, and coliform bacteria. Bacterial growth accelerates especially in hot weather.
2Health Risks
Dirty water tanks can cause gastrointestinal infections, diarrhea, typhoid, cholera, and Legionnaire's disease. Children, elderly, and immunocompromised individuals are especially at risk. Changes in water color, smell, or taste are the first warning signs.
3Cleaning Frequency
Water tanks should be professionally cleaned at least twice a year (at the start of summer and winter). Clean immediately if there are cracks, rust, or changes in water color. Building managers are responsible for tracking this process.
4Professional Cleaning Process
1. Tank draining, 2. Mechanical cleaning (scrubbing), 3. Disinfection (chlorine application), 4. Rinsing, 5. Water sampling. The entire process takes 2-3 hours and a certificate is provided afterward.
5Legal Regulations
According to Ministry of Health regulations, all water tanks must be regularly cleaned and reported. Building managers are responsible for apartment buildings. Legal sanctions may be applied if cleaning is not performed.
