Using Pool Water for Irrigation: Safe for Plants?

Wondering if you can water your sugar maples and bermudagrass with swimming pool water? The short answer: yes, it's generally safe.

Chlorine Levels Compared

Pool water typically contains 1-3 parts per million (ppm) of chlorine—roughly the same concentration as most municipal tap water. At these levels, chlorine dissipates quickly when exposed to air and soil, posing minimal risk to established landscape plants.

Best Practices

• Test first: Verify chlorine levels are within normal range (1-3 ppm).
• Dilute if needed: If recently shocked, wait until levels normalize.
• Apply normally: Use pool water just as you would tap water for irrigation.
• Monitor plants: Watch for any signs of stress, though unlikely at typical concentrations.

Considerations

Saltwater pools (using salt chlorine generators) have slightly higher salinity, but still generally safe for occasional use on tolerant plants. Avoid using on salt-sensitive species like azaleas or blueberries regularly.
