Can Swimming Pool Water be Used for Plants?

Swimming pools are a great way to cool off during hot summer days. However, swimming pools also require regular maintenance, including the addition of various chemicals to keep the water clean and safe for swimmers. But what happens to the water after it has been treated? Can swimming pool water be used for plants? Let's explore this question in more detail.

The Chemicals in Swimming Pool Water

Before we can determine whether swimming pool water is safe to use on plants, it's important to understand the types of chemicals that are typically added to the water. Chlorine is the most common chemical used to disinfect swimming pools. It is highly effective at eliminating harmful bacteria, viruses, and other contaminants in the water. However, if the concentration of chlorine is too high, it can be harmful to plants.

In addition to chlorine, other chemicals such as algaecides and pH balancers may also be added to the water. These chemicals can alter the pH level of the water, which can make it difficult for plants to absorb the nutrients they need to grow. In some cases, the chemicals in swimming pool water can be toxic to plants, causing them to wilt, turn yellow or die.

Using Swimming Pool Water on Plants

While swimming pool water can be used on plants, it's important to take certain precautions before doing so. First, the water should be tested to determine its pH level and chlorine concentration. Ideally, the pH level should be between 6.0 and 7.5 and the chlorine concentration should be less than 0.5 parts per million (ppm).

If the pH level or chlorine concentration is too high, the water should be diluted with fresh water until it is within the recommended range. It's also important to avoid using swimming pool water on plants that are sensitive to chlorine, such as ferns, succulents, and citrus trees.

The Benefits of Using Swimming Pool Water on Plants

Despite the potential risks associated with using swimming pool water on plants, there are also some benefits. For example, using swimming pool water can help conserve water, especially during droughts or other times when water is scarce. Additionally, the minerals and nutrients in the water can provide some essential nutrients to plants.

Using swimming pool water on plants can also help reduce the amount of chemical runoff that enters streams, rivers, and other bodies of water. When pool water is discharged directly into storm drains or nearby bodies of water, the chemicals can harm fish and other aquatic life.

The Bottom Line

So, can swimming pool water be used on plants? The short answer is yes, but with some caveats. If you decide to use swimming pool water on your plants, it's important to test the water and make sure it's within the recommended pH and chlorine concentrations. You should also avoid using the water on plants that are sensitive to chlorine. By taking these precautions, you can help conserve water and promote healthy plant growth while minimizing the environmental impact of swimming pool maintenance.
