Mr. Boucher
Yes, it’s sodium bisulfate that removes the sodium hypochlorite.
Alderman Klee
And the reason you needed this was because — we haven’t had a whole lot of rain or anything else like that.
Mr. Boucher
But we had process upsets throughout the year. Process upsets can come, there’s temperature changes that
can cause upsets. Increased solids coming into the facility can cause upsets, there’s several things that can
cause upsets. But we have to add chlorine because if there’s more solids that make it through the process, we
have to treat it, it takes more chlorine, it uses up more chlorine because that’s what this is, it is chlorine.
Alderman Klee
Thank you so much, | appreciate your answer.
Mr. Boucher
You’re welcome.
Mayor Donchess
Alderwoman Kelly?
Alderwoman Kelly
| think | have a somewhat ridiculous question but your comment about upsets in the system, has there been a
higher impact on the wastewater treatment plant with people working and being at home more.
Mr. Boucher
It is hard to tell where — a lot of it is temperature. Usually people being at home more, there’s more rags and
when we had a shortage of toilet paper, people were using other things that cause problems. But no it is hard
to tell what causes the upset sometimes. It is a very sensitive process because it is organic life we are trying
to keep alive; they are sensitive. They need the right amount of oxygen, the right temperature so it is a tricky
balance.
Alderwoman Kelly
| appreciate your answer. Thanks.
Mr. Boucher
You're welcome.
