What should be done before putting a tank back into commission after maintenance?

• A. Only fill the tank with water
• B. Inspect the exterior for damage
• C. Disinfect the tank and test for coliform bacteria
• D. Paint the interior surfaces

Answer: (C)

Before putting a tank back into commission after maintenance, disinfecting the tank and testing for coliform bacteria is essential to ensure safe water quality. This process involves cleaning the tank to eliminate any harmful pathogens, biofilms, or residues that may have accumulated during maintenance. Testing for coliform bacteria is a crucial step in verifying that the disinfection process was effective and that the water supply is safe for consumption. Coliform bacteria are indicators of possible contamination and their presence raises concerns about the safety and potability of the water. Disinfection helps to prevent any health risks associated with pathogens, which is critical for maintaining water quality standards and public health compliance. Therefore, this practice ensures that the tank is not only physically ready for use but also safe for the distribution of water.
