safetygem, What is the difference between the two types of wwtp that you mentioned?
To everyone else, thank you for your comments.
My supervisor & I were talking about this subject again today and he mentioned that our company is bidding on another wwtp with the same design (mixing low voltage & communications with power wiring) and it is by a different engineer. He also said that the engineer referred him to a publication that allows this at a wwtp. I intended to find out what the publication was before I left today but I forgot. I"ll try to remember for Monday.
