Fourth, dispose of any treated water very carefully. You may likely pour the treated water down your drain, but use caution. Large volumes of chlorinated water may cause problems for your wastewater treatment facility. Check with the facility's operators to see if they have any special concerns or suggestions. Fifth, know where your drain goes.
Some floor drains go directly to a storm sewer or open body of water.
It's best to avoid these. Passing the treated water through a wastewater treatment plant further ensures that no mussels survive your treatment efforts. Zebra mussels and other exotic organisms can be effective teaching tools for a variety of biological topics. However, careless use of any exotic species will likely result in an undesired, costly lesson-both in terms of potential repairs and in terms of adverse ecological effects on your local aquatic ecosystems.
