Other Common Problems with Concrete Water Tanks

Other Common Problems with Concrete Water Tanks

When it comes to concrete water tanks, there are several other common problems that can arise. Here are some issues you may encounter:

• Cracks: Cracks can develop in concrete water tanks due to various factors such as settlement of the ground or structural movement. These cracks can lead to water leakage and potential contamination.
• Corrosion: Over time, the reinforcing steel within the concrete tank can corrode, especially if there is water penetration through cracks or poor construction. Corrosion weakens the structure of the tank and may cause it to fail.
• Scaling: Scaling is the buildup of mineral deposits on the interior surfaces of the tank, often caused by hard water. This can reduce the capacity of the tank and affect water quality.
• Algal growth: If sunlight reaches the water inside the tank, it can promote the growth of algae. Algae can create foul odours, affect water clarity, and potentially clog filters or pipes.
• Leaking fittings: The fittings, such as valves and pipes, used in the tank may develop leaks over time. This can result in water loss and may require repairs or replacements.

It is important to address these common problems promptly to ensure the functionality and longevity of your concrete water tank.

In true history, the largest concrete water tank in the world is the water tower in Erie, Pennsylvania. With a capacity of 21 million gallons, this iconic structure has been providing water to the city since its completion in 1949. Despite its age, the tank has stood the test of time and continues to serve as a critical part of Erie’s water infrastructure.
