Do Cisterns Require Regular Cleaning and Maintenance?

Importance of Regular Cleaning and Maintenance

Buried concrete cisterns, in particular, can be prone to contamination from soil and groundwater. Sediment and debris can accumulate at the bottom of the cistern, while mosquito larvae, bacteria, and other microorganisms can multiply in stagnant water. Regular cleaning and maintenance are crucial to prevent these issues and ensure a safe and reliable source of water.

Suggested Maintenance Schedule

The frequency of cleaning and maintenance will depend on the cistern’s usage, climate, and water quality. As a general rule, it’s recommended to inspect and clean the cistern at least once a year, and more frequently in areas with heavy rainfall or high water usage. Here’s a suggested maintenance schedule:

• Every 3-6 months: Check the cistern’s water level, inspect the lid and surrounding area for signs of damage or debris, and ensure the overflow pipe is functioning properly.
• Every 6-12 months: Remove any sediment or debris from the bottom of the cistern using a submersible pump or a siphon hose.
• Every 1-2 years: Perform a more thorough cleaning, including scrubbing the walls and floor of the cistern with a brush and mild detergent, and disinfecting the area with chlorine or other approved disinfectants.

Tips for Effective Cleaning and Maintenance

When cleaning and maintaining a buried concrete cistern, it’s essential to take precautions to avoid contamination and injury. Always wear protective gear, including gloves, safety glasses, and a face mask. Use a submersible pump or siphon hose to remove water from the cistern, and avoid using electrical equipment near water. Finally, ensure the cistern is properly sealed and secured after maintenance to prevent unauthorized access or contamination.
