Quick Answer
Cistern maintenance is crucial to ensure clean, healthy water storage. Regular tasks should be performed to prevent contamination, maintain water quality, and extend the lifespan of the cistern. These tasks include inspecting the cistern's interior, cleaning filters, and testing water quality.
Inspecting and Cleaning the Cistern
Inspect the cistern’s interior every 6-12 months, looking for signs of algae growth, sediment, or animal infestation. Use a submersible pump to remove any debris or sediment that has accumulated at the bottom of the cistern. Clean the cistern’s walls and floor with a mild detergent and a scrub brush, taking care not to scratch the surface. Rinse the cistern thoroughly with clean water.
Maintaining Cistern Filters and Intakes
Regularly inspect and clean the cistern’s intake screens and filters to ensure they are free from debris and sediment. Replace filters every 3-6 months, or as recommended by the manufacturer. Consider installing a sedimentation chamber or a self-cleaning screen to reduce maintenance tasks.
Monitoring Water Quality
Test the water quality in the cistern every 3-6 months, checking for pH, turbidity, and bacterial levels. Use a water testing kit or send samples to a certified laboratory for analysis. Adjust the cistern’s maintenance schedule based on the water quality test results, taking corrective action if necessary to prevent contamination and maintain healthy water storage.
