tank. Does the Storage tank foundation does not appear to be structurally sound. (see photo # The storage tank foundation does not appear to be structurally sound. It must be evaluated by a professional engineer familiar with the construction of water-storage tanks. Failure to maintain the structural and sanitary integrity of the tank foundation could lead directly to contamination within the tank, illness and/or the loss of property. The professional evaluation of the storage tank foundation must be made as soon as possible and the foundation repaired if necessary to ensure the structural integrity and reliability of the tank. Are there any in the tank leaks, etc)? Storage tank not sealed. (see photo #) Other than the openings afforded by the #24 mesh screens on the vents and overflows, all openings must be sealed completely to prevent contamination (including contamination carried by insects, rodents, and birds) from entering the water system. [Describe specific openings such as: All openings between the roof and sidewalls must be sealed and watertight. Any openings from antennas, telemetry, and other appurtenances must be sealed and watertight.] If the tank is more than 10 years old, was it and within the last 10 years? Storage tank not cleaned and inspected within the last 10 years. The tank must be cleaned and inspected. Please see the enclosed Finished Water Storage Tank Checklist for a list of items that must be evaluated during the inspection. need to be periodically cleaned and inspected to prevent the growth of potentially harmful pathogens in the accumulated sediments and to address construction issues before they require major repairs. Inspections and cleaning may be done by a professional or appropriately trained in-house staff. Please be aware that some tanks may be considered as confined spaces or hazardous environments; personnel
