I would try Lemishine. It's made to remove mineral deposits from dishwashers, but you can safely use it on diapers. The brown in the water is most likely minerals, so I would think it would work well. Good luck, mama! I would be furious. If Calgon and/or Lemishine doesn't work, I would contact the city and try to get them to replace what they ruined.
