Quick Answer
A cistern that needs repair may show signs of water leakage, corrosion, or structural damage, such as cracks, rust, or holes in the walls or bottom. Water levels may fluctuate or drop rapidly, indicating a leak. The cistern's surroundings may also be affected, with signs of water erosion or damage to nearby plants.
Identifying Signs of Water Leaks and Corrosion
Water leaks are often the most common issue with cisterns. To identify a leak, inspect the cistern’s walls and bottom for signs of water damage, such as rust, holes, or cracks. Check for water droplets or mineral deposits on the surrounding surfaces. Look for areas with uneven or loose mortar between bricks or stones. Use a water test: mark the water level, then turn off the source of water and wait 24 hours. If the level changes, there’s a leak.
Assessing Structural Damage
Inspect the cistern’s walls and roof for signs of structural damage. Check for cracks, gaps, or loose joints between bricks or stones. Look for water damage to the surrounding soil or vegetation. Use a level tool to check the cistern’s walls for any signs of leaning or tilting. If the walls are not level, it may indicate a structural issue.
Sizing a Cistern for Optimal Performance
A well-sized cistern is essential for optimal performance. A general rule of thumb is to size the cistern based on rainfall data for your area. A good starting point is to size the cistern to hold at least 1-2 inches of rainfall per day. For example, if your area receives 2 inches of rainfall per day, a 2,000-gallon cistern would be a good starting point. However, this calculation should be adjusted based on your specific needs and climate. Consult local experts or use online tools to determine the optimal cistern size for your area.
