President Wilshire
Okay, thank you.
Alderman Klee
Again, thank you Madam President and I'm glad you brought up the CSO because that was what my question was. |
have a couple of questions relative to that and basically where are they located. But before that when we do open and
we do put into the Nashua River and the Merrimack River, | know we dilute as much as possible but I've heard that you
should stay away from the area for 24 hours. | know that Manchester sends out a report that this has been happening.
The reason | bring this up is | have a constituent who is very keen on getting these reports in real time as possible.
Manchester does seem to put out an alert. | think Lowell does the same thing. We do put out the information, but its
well after the fact after that 24 hour period where people should be avoiding that area. Is there anything that we can do
to make that more real time is my first question and then part of that is also is where are these CSOs located? | know
you said five on the Merrimack and four in the Nashua River.
Dave Boucher, Wastewater Superintendent
So we do have flow meters that measure the flow leaving. We do get reports. We do have to verify the data before we
put it out there because sometimes we have false readings. When these do go off, it's usually a major storm - the rivers
are high. It does take a while for the rivers to recede so no one is using the river typically. We don't usually have dry
weather discharges but we do post the discharge on our site - the city's website. How soon is that done?
Noelle Osborne, Plant Operations Supervisor
Within 24 hours.
Dave Boucher, Wastewater Superintendent
So we do do that and at all these sites, it is posted. We do have signs that kind of indicate that there is CSO outfall here
and what would be discharged? Don't go into the river during this time. The specific locations - | don't know if you have
specific locations.
Noelle Osborne, Plant Operations Supervisor
They are on the website on the wastewater portion of the website. There are addresses of all the locations.
Alderman Klee
That's perfect. Thank you that does answer the question.
Dave Boucher, Wastewater Superintendent
Sometimes they don’t have street addresses so it's hard to describe where they are.
Alderman Klee
That's absolutely fine. | can look that up myself and | do appreciate that. Madam President if | could...| had to look up a
word that was in there and it was septage. | looked at it and went okay - 800 gallons of that. So that comes through the
Nashua wastewater is that what you're saying?
Dave Boucher, Wastewater Superintendent
Yeah, correct. The septage is if your house if you're not near a gravity sewer main, you might have a septic tank out
your yard. You'd have to have it pumped every other year or every four years. A truck would pick that up and bring it to
the wastewater facility for treatment.
Alderman Klee
Do we have septic tanks in Nashua?
