Storm drains provide a convenient way to recycle water. Most storm drains capture water, which prevents flooding, then drains into nearby streams or saturates into ground soil. Odour can form in the storm drain from time to time, either when things fall into the drain and begin to rot, animal faeces gets into the drain, or other elements that lead to the development of an unpleasant odour. It is important to use safe products when getting rid of the odour, as using harsh chemicals will lead to water and soil contamination.

  1. 1

    Fill a bucket with a 50/50 solution of hot water and white vinegar. The vinegar is a natural disinfect and deodoriser. This means not only will odour be removed, but the vinegar is a natural element that will also kill any bacteria that leads to odour development.

  2. 2

    Pour 2 cups of baking soda into the bucket also. This is another natural cleaning and deodorising agent.

  3. 3

    Pour the bucket of cleaning solution down the drain slowly, and repeat daily until all odour has dissipated.

Tips and warnings

  • Never use bleach in storm drains, as most storm drains run into a stream or groundwater supply. Using a harsh chemical such as bleach can kill wildlife and contaminate water and soil.
