RE: UV light disinfectant
In another career long ago, I submitted a bid to our municipal water treatment facility to install six 8” pipe size UV radiation devices. They were to be installed in the lines that fed the three water towers (actually concrete tanks situated on a nearby high hill). I was fascinated by this concept. The devices were furnished; we were to install. I have no clue as to the cost of these. Probably happened around 2008.
The doctor on Laura Ingraham last night said the lights for a restaurant would now cost around... $150
