Alderman Caron
Yes big time.
Ms. Gill
That whole neighborhood too, the Marshall Street area, Ald Street.
Alderman O’Brien
Thank you. Ms. Gill | completely understand, | used to work at the Arlington Street Station and | know it is a
very ancient system, it is one of the oldest in the City if | think what it is.
Ms. Gill
That is correct, it is the closest to the oldest.
Alderman O’Brien
If we were going to build a Nashua we could not build that type of sewer system, a combination system like
that today. But as we replace with modern upgrades, which | fully support, if we had damage at Chase Street
we had to get to that first and | completely understand that. Are we doing anything to help mitigate the odor or
anything when we look at the upgrades, are there any P-trap system or anything else that we could put in that
as we change them, can we alleviate some of that.
Ms. Gill
Depending on what we are trying do at that location, the odors generally come from the catch basins which are
also connected to the combined system that is one pipe that takes the sanitary waste from the household as
well as the runoff into the catch basins. The catch basins in the older systems are shallower and that is where
the odor is allowed to come out of the catch basins without being stopped by any water that typically might be
in a catch basin. A lot of that depends on funding, if we were to replace all the catch basins at the time we did
the sewers we would exhaust our dollars. But in known areas we do take care of the catch basins, when we
can correct.
Alderman O’Brien
If | may follow up, | completely understand we can’t do them, it would be separate, but it would be nice and it
sounds like we are, the ones we are getting to we are upgrading as best we can. But that’s all | think we can
do.
Ms. Gill
The best we can. And the interesting thing just to point them out on Chase Street area and those areas down
by Crown Hill, those pipes are the deepest pipes because the system is set up to be a gravity system, as you
get closer to the water, the pipes are deeper so it does cost us more money to replace these sewers.
Unfortunately we try to catch the sewers before they need replacement, we are doing a huge lining project in
order to try to capture those pipes when their condition is still that they can be refurbished through the interior
be lining those pipes so it is a lot less expensive.
Alderman O’Brien
Thank you.
