Preventing Harmful Chemicals from Entering Storm Drains
Updated: Aug 8, 2025
If you see stormwater pollution, call the Stormwater Helpline at 919-996-3940 or email IllegalDischarge@raleighnc.gov.
Chlorinated or salt water from pools can pollute streams and creeks. This happens when chlorine and other pool chemicals enter a storm drain or stream. You can help protect the environment by making sure only rain goes down the storm drain. When you are maintaining a private or public pool – do not pump or drain water into the stormwater system.
Don’t have a grassy area? De-chlorinate and test the pool water to make sure chemical levels are low before releasing it. Visit a pool supply store for instructions.
