Quick Answer
A damaged concrete cistern may exhibit signs such as cracks, holes, or crumbling surfaces, water leakage, uneven settling, and visible damage to the tank's internal linings or coatings. These symptoms can compromise the cistern's integrity and affect the quality of stored water. Regular inspections can help identify potential issues.
Visual Inspection Indicators
A thorough visual inspection is essential to identify potential damage to a buried concrete cistern. Look for cracks or holes in the concrete surface, especially around the tank’s outlets, inlets, and where the tank meets the surrounding ground. Check for uneven settling, which can indicate soil settlement or improper foundation. Measure the depth and width of any visible cracks to assess their severity. Use a flashlight to inspect the cistern’s interior, checking for signs of water damage, rust, or corrosion on metal components.
Water Quality and Quantity Issues
Damage to a concrete cistern can lead to contamination and decreased water quality. Inspect the tank’s internal linings or coatings for signs of wear, cracks, or holes. Check the water level and flow rates to ensure the cistern is functioning correctly. If water is leaking from the tank, inspect the affected area to determine the cause and potential repair options. Consider testing the stored water for pH levels, bacteria, and other contaminants.
Repair and Maintenance Techniques
If a damaged concrete cistern is identified, repair or replacement may be necessary. For minor damage, apply a concrete patching compound to fill cracks and holes. For more extensive damage, consider hiring a professional to assess and repair the tank. Regular maintenance can help prevent damage, including inspecting the cistern annually, cleaning the interior, and applying a protective coating to the concrete surface.
