Pools and Spas


Wastes generated form pool, spa, and fountain cleaning are among the common stormwater pollutants that can degrade water quality.  Routine pool maintenance activities generate a variety of wastes.  Chlorinated pool water, backwash residues, algicides, and acid washes are a few examples.  It is illegal to dispose of these wastes to the storm drain system!  Pool drain water may be disposed to the storm drain system only if the chlorine is below 1 part per million and only if the water contains no other contaminants such as backwash residues or algicides.  Note: Chlorine, bromine, and algicides can kill aquatic life.



What can I do?

Use Best Management Practices (BMPs)!
BMPs are techniques or controls used to prevent or reduce the discharge of pollutants, such as oil, antifreeze, and solvents, into the stormwater conveyance system also known as the storm drain system.
