A well-maintained rainwater tank can provide you with a reliable source of water for various household and agricultural purposes.

Step-by-Step Guide:

  1. Regularly inspect your tank: Frequent visual inspections of your rainwater tank can help you identify any issues, such as leaks, cracks, or signs of wear and tear. Addressing these problems early on can prevent more severe damage and save you money on costly repairs.
  2. Keep gutters and downspouts clean: Clean gutters and downspouts are crucial for preventing debris from entering your rainwater tank. Regularly remove leaves, dirt, and other debris from your gutters and ensure your downspouts are free of blockages.
  3. Install and maintain filters and screens: Installing and maintaining filters and screens at the tank inlet can help to keep debris, insects, and other contaminants out of your rainwater tank. Regularly clean and replace filters and screens as necessary to maintain optimal water quality.
  4. Monitor water quality: Regularly check the water quality in your tank by filling a glass and observing its clarity and smell. If you notice any unusual odours or discolouration, your tank may require cleaning or further investigation.
  5. Clean your tank roof and surrounding area: Keep the roof of your rainwater tank clean by using a leaf blower or garden hose to remove debris. Maintain the area around your tank by trimming overhanging branches and removing potential sources of contamination.
  6. Schedule periodic professional cleanings: Even with diligent maintenance, it is essential to schedule professional cleanings for your rainwater tank. A professional cleaning service can thoroughly clean the tank's interior, remove sediment build-up, and inspect the tank for any issues.
