EGLE offers tips for the proper disposal of residential pool water

Labor Day marks the traditional end of summer when pool owners must dispose of pool water.

At this time of year, EGLE hears from many homeowners who wish to dispose of chlorine-based pool wastewater into the ground, into a storm sewer, or into another surface water body.

If an owner with a chlorine-based pool meets the following conditions, they generally meet the conditions for a sewage discharge permit, without having to apply for and obtain one:

  • Leave the pool uncovered and exposed to the sun for at least two weeks to remove chlorine from the water
  • Filter backwash waste water cannot be discharged.
  • No solids should be released with the water (eg leaves, dirt).
  • Spa water must be cooled before being discharged.

If discharge is planned directly into surface waters, it should be done slowly and in a manner that prevents erosion. If a discharge is provided to the ground, it must be carried out in such a way that all water remains on the property of the owners of the pool and that the discharge does not cause physical damage or nuisance conditions (such as flooding ) on neighboring properties.

More information is contained in this document which covers domestic wastewater discharges into state groundwater.

Please note that saltwater pools and non-residential pools cannot be discharged into storm sewers or surface waters without applying for and obtaining a permit.
