Water storage tanks are important for homes and businesses, especially where water supply is unreliable. They store water for future use, but over time can collect dirt, bacteria, and other contaminants. To keep your water safe for drinking, cooking, and other uses, it’s essential to clean and maintain your tank regularly.
How often should you clean it? That depends on the type of tank, water quality, and how often it’s used. But a general rule is to clean your tank twice a year.
Recommendation: Twice a Year
It’s advised to clean your water tank every six months. Regular cleaning removes sediment, algae, bacteria, and other contaminants, ensuring your water stays clean and reducing the risk of harmful organisms.
However, some factors may require more frequent cleaning:
- Water Quality
If your water has a lot of minerals, debris, or impurities, clean the tank every 3-4 months. Hard water, for example, can leave mineral deposits that affect water quality. - Tank Type
Plastic tanks are less prone to rust but can still get algae. Metal tanks may rust and need more maintenance. Underground tanks are less exposed to light, which can reduce algae growth but still need cleaning. - Tank Location
Outdoor tanks collect more dirt, debris, and insects. These may need cleaning every 3-4 months to keep contaminants out. - Tank Usage
If you frequently empty and refill the tank, contaminants have less time to settle, meaning less cleaning. But if the tank is rarely used, clean it more often to prevent stagnation. - Algae Growth
Algae thrives in sunlight. If you see green or brown algae in your tank, clean it every 3 months to keep water quality high.
Steps to Clean Your Water Tank
- Drain the Tank
Empty the tank to reach all areas, especially the bottom where dirt gathers. - Scrub the Inside
Use a brush or sponge with soap to clean the tank walls and bottom. For tough stains or algae, use a bleach solution (1 tablespoon per gallon of water) and rinse thoroughly. - Rinse
Rinse the tank with clean water until no dirt or soap remains. - Sanitize
Disinfect the tank with a bleach solution (1 part bleach to 100 parts water). Let it sit for a few hours, then drain and rinse again. - Refill
Once cleaned, refill the tank with fresh water and seal all openings to prevent contamination.
Signs Your Tank Needs Immediate Cleaning
- Strange odor, taste, or color in the water.
- Visible debris or sediment in the water.
- Algae growth on the tank walls.
- The tank hasn’t been cleaned in over a year.
Conclusion
Cleaning your water tank twice a year helps keep your water safe. Depending on factors like water quality, tank type, and location, you may need to clean it more often. By following a regular cleaning schedule and addressing signs of contamination, you’ll ensure your water stays healthy for you and your family.
