Rain barrels offer many benefits, but they also require some maintenance to ensure clean water and long-term performance. Whether you’re watering your garden or filling a pool, proper upkeep will help keep your barrel in good shape.
Over time, leaves and small debris can enter the barrel through the downspout, leading to hose blockages and water contamination. This debris can break down and make the water cloudy—unsuitable for most uses. Cleaning out leaves at least once a year is essential. Gutter protection systems like T-Rex®, DoublePro®, or Gutter Clean System® help minimize the amount of debris that enters the barrel, reducing maintenance.
Algae can form inside the barrel, especially if it's translucent and lets in light. To prevent this, clean the interior with a long-handled brush and a mix of water and bleach. This is particularly important if the barrel wasn’t emptied before winter.
Each spring, inspect all pipes and connectors to ensure they’re in working condition. If water wasn’t fully drained in the fall, freezing temperatures could have caused damage.
If you’re thinking about drinking the collected water, take proper precautions. Water from rooftops—especially those with asphalt shingles—is not recommended for consumption or for watering edible plants. If you do want to use it for drinking, the Red Cross advises boiling the water for at least one minute and then adding a small amount of chlorine bleach. However, it’s generally safer to reserve rainwater for non-potable uses like watering lawns and gardens, washing vehicles, or filling pools.
While rain barrels do require some basic maintenance, they remain a simple and eco-friendly solution for collecting and reusing rainwater efficiently.
