Dear Ms. Wright:
The deodorizer we currently use is what is known as a "floater". It creates a film on top of the raw sewage
and prevents the odors from escaping through the vents. It does not mask the odor with something that
smells better. There are many different types of deodorizers on the market. We have experimented with
most of them and have found that this one works the best. It should last six months or more. We have
never gone that long without replacing it. When the lift station is working properly, it will always leave
several feet of sewage in the wet well including the floater. The lift station sensor will malfunction
occasionally and suck the wet well dry including the "floater". When the sensor does malfunction, we
replace the floater. It occurs about every two or three months on average.
In order to help solve the odor problem, I have instructed the crew to add the deodorizer at the beginning
of each month and whenever the sensor malfunctions. We will try this for several months and see if it will
solve the odor problem. If you continue to experience bad odor problems, please contact me and be sure
to include the time of day the problem existed. This will help us to determine if there are other problems
besides the deodorizer.
We are currently in the process of choosing a consultant to design the upgrade to the station. Once the
consultant begins designing the new station, we will look at all of the odor control methods currently
available and determine which one will best suit our needs. I am sure you will be much happier with the
new station. Until that time, we will try to keep the odor to a minimum.
If you have any further comments or questions, do not hesitate to contact me.
Sincerely,
Glenn D. Hollowell, P.E.

Glenn-
As you can see I am copying in my husband who will be dealing with you on
this---but a few comments. First, I am not sure how you keep up with
complaints on the Lift Station but I know that we have sent over 25 letters
and faxes and I know that the people who live down wind from the station
have called in the past---from my perspective, ours alone should be consider
a lot!
Secondly, I would like to know what steps must be taken by us to ensure that
the deodorizer is put on a pro-active schedule rather than a reactive
schedule (i.e. petition, letters, bring it to the Council???) I consider
the current process an inadequate solution and something needs to change.
As far as what will be done in the future, I will let my husband address as
to its effect or lack of effect on the "quality of living" in our area when
the changes occur.
I appreciate your response and please forward messages to both of us. Thank
you.

Dear Mr. Wright:
We added deodorizer to the lift station on Monday, August 23,1999, after we
received a copy of your fax to Ken Griffin. We do not have a set schedule
for adding deodorizer to the lift station. The lift stations are checked
every morning and we add deodorizer if we perceive there is an odor problem.
We also investigate complaints about odor problems when we receive them. We
have had very few complaints about odors at this station.
We are scheduled to enlarge the Deforest Lift Station this winter. We will
expand the capacity of the station by converting the dry well to a wet well
and moving all of the electronics above ground. The consultant that designs
this expansion will make reccommendations on controlling the odor problem.
We will investigate all of the options and determine what will be the best
odor control for this station. There have been many new technoligies
developed in odor control since this station was first installed.
If you have further questions regarding this matter, do not hesitate to call
me at (972) 304-3545.
Sincerely,
Glenn D. Hollowell
