Draining Your Swimming Pool

Summer is coming to a close and many swimming pool owners are preparing their pools for winter.  When draining your pool, please keep in mind that the water from your pool can have a negative environmental impact if not done properly. The chlorine and other chemicals that are added to swimming pools  can be harmful to fish and wildlife so here are some guidelines for safely draining your pool:

  • If possible, discharge swimming pool water to a sanitary sewer.
  • If draining to the sanitary sewer is not possible from your site, stop chlorinating a week or so prior to emptying your pool to allow the chlorine to dissipate.
  • Check the chlorine level with your pool test kit before emptying the pool to make sure that the chlorine is less than 0.1 milligrams per liter (mg/L)
  • Dispose of the pool water slowly onto your property and use it to irrigate your lawn or allow it to infiltrate into the soil.  If the water will eventually make its way to a stream, allow it to flow across a grassy area first.
  • Empty the pool in a way that ensures that the water does not flow onto a neighbor’s property.
  • Empty your pool in a way that does not result in the water pooling for more than a couple of days so that it does not become a mosquito breeding spot.

The City’s storm drains lead to our brooks, rivers, ponds and wetlands.  Please protect our fish, wildlife and waters by following these practices when draining your pool.
