Know Your Chlorine Level Before Emptying Your Pool

Overview:

Properly dechlorinating your pool before draining helps protect local waterways and is required by City ordinance. A few simple steps can prevent harmful chemicals from entering the environment and affecting your neighborhood.

Dechlorinating your swimming pool before emptying it is required by City ordinance. Improper drainage can introduce pollutants into stormwater systems, including chlorine, copper, and mosquito larvae. Pool chemicals used for maintenance can be harmful to fish and other aquatic life, making proper disposal important.

Before draining your pool:

• Stop adding chlorine and allow the water to sit undisturbed for at least five days so chlorine can naturally dissipate

• Test the water to ensure the residual chlorine is at or near zero (below 1 ppm, or parts per million)

When draining your pool:

• Never drain pool water into the street or a storm drain

• Drain water onto your yard in an area where it can soak into the ground

• Avoid directing water toward neighboring properties to prevent flooding

Why this matters:

• Chlorine and other pool chemicals can harm aquatic life

• Storm drains carry untreated water directly to local waterways

• Improper drainage can contribute to pollution and mosquito breeding

By following these guidelines, you help protect the environment, comply with local regulations, and support a safe and healthy community.
