You never know what special circumstances might arise when inspecting an industrial water tank.  Our crew in Florida got an unexpected surprise last month when they reached the top of this water tank.

A family of raccoons greeted the inspector on the ladder!

The presence of raccoons inside an industrial water tank could be the result of several possible scenarios.  In this case, the tank had been out of service for several years. Since it wasn’t in use, routine maintenance may have been overlooked. Deterioration of the steel provided openings for contaminants. Raccoons are known for their agility, so they are capable of finding their way into various places. Water tanks should be properly sealed and protected to prevent wildlife from entering them.

Another way contaminants can enter a tank is through a failed screen on a vent. If the screen is damaged or missing, it allows the entry of debris and contaminants. The primary purpose of screens on vents is to prevent the entry of debris, insects, animals, and other contaminants into the tank. This can include leaves, sticks, and bird droppings which increases the risk of water contamination. Debris and contaminants that enter the tank through the open vent can mix with the water, compromising its quality and safety. This can result in the presence of pollutants, bacteria or other harmful substances in the water supply.

If the tank is still in use, it can also clogging and reduced water flow. Debris entering the water tank can accumulate over time and lead to clogging issues.  This can obstruct the flow of water within the tank, impacting the water pressure and distribution.  Reduced water flow can cause inconvenience and affect the efficiency of the water system.

If larger debris enters the water tank it may cause harm to the pump, float switches, or other equipment inside the tank.  This can result in mechanical failures and require costly repairs or replacements.

Are there guidelines and recommendations for water tank inspections?

Yes, there are guidelines and recommendations for water tank inspection to ensure the safety and quality of the water supply.  These guidelines may vary depending on the use of the tank.  If the tank is used for fire protection, the National Fire Protection Association recommends that fire protection tanks without cathodic protection be inspected and cleaned out every three years.  Tanks with cathodic protection used for fire protection are only required to be inspected every 5 years.

The American Water Works Association recommends tanks be inspected every 3 years.
