... they call it the "caustic room" ... I wasn't wild about going in it to begin with and we weren't supposed to without an escort so we shot it with the doors open at a distance ..... love those zoom lenses. We shot  Dempsey Water Purification Plant in North Carolina  in May and learned how awful water is made drinkable.... by noon it was too much information. We shot this for a specialty construction company that builds these very specialized facilities. It is amazing what goes into ( and out of for that matter ) making clean water. 

I don't leave myself in images typically but we had 2 cameras operating to get 2 slightly different perspectives for the client to choose from .... what an extraordinary night ! The rep from the company was a great guy to work with and we really had a great time documenting this project for them.
