I used to work for a rather large Water & Sewerage Company, one of my many hats was to head up the DHS mandated Vulnerability Assessment of our system. I conducted a complete system analysis and submitted my 245 page report on the system, in which I recommended securing access to our water storage and supply facilities, to my General Manager and the DHS. My managers response to my report was to tell me that his system was not that insecure and that I could pick up my final paycheck in a week.
The people in charge don't want to admit that there is a security risk, they just want to keep drawing those checks for basically doing nothing, except promoting the yes men and getting rid of anyone that raises concerns.
