Copied forward because I got behind.

The reverse osmosis unit filters do need to be replaced. The home units the village bought need them changed annually. Culligan provided the new r/o units and they change and dispose of them under contract annually. Because the filters take out hazardous materials (arsenic and uranium), Culligan disposes of them through a hazmat service.

As for the small amount of wastewater produced by the r/o units, that is shunted into the sewage system.
