What is the last treatment step before water storage?

• A. Filtration
• B. Sedimentation
• C. Coagulation
• D. Disinfection

Answer: (D)

Disinfection is the final treatment step before water is stored. This process is crucial for eliminating pathogens and harmful microorganisms that can pose health risks to consumers. Various disinfection methods, such as chlorination, ultraviolet light, or ozone, are employed to ensure that the water is safe for distribution and consumption. After disinfection, water is typically stored in tanks or reservoirs, ready for delivery to users. This step is essential to maintain public health standards and prevent waterborne diseases. The earlier processes, such as coagulation, sedimentation, and filtration, serve to remove particulate matter and impurities from the water, but they do not provide the same level of microbial safety that disinfection does. Thus, without the disinfection step, stored water could still harbor pathogens, making it unsafe to drink.
