Why Clean Your Water Tank Every 6 Months
Dubai’s hot, humid climate creates ideal conditions for bacteria, algae and biofilm to accumulate inside water tanks. Without regular cleaning, pathogens like Legionella, E. coli and Giardia can contaminate your water, leading to serious health risks such as skin infections, hair loss, gastrointestinal illness and even respiratory issues.
To ensure public health, the Dubai Municipality and World Health Organization (WHO) recommend professional water tank cleaning every six months. Compliance with Dubai Electricity and Water Authority (DEWA) water safety standards also supports this routine. Regular disinfection helps maintain optimal pH and chlorine balance, ensuring your water is safe for everyday use.
HACCP-compliant procedures
Municipality-approved sodium hypochlorite disinfectants
Environmentally responsible & safe for children and pets
Stay safe and protect your family by ensuring your water tank is professionally cleaned and disinfected at least twice a year.
