Dear Board Members:
Camo Pollution Control operators at the Sanitary Sewage Collection
System for Wappinger Sewer Improvement Area No.1 have completed a
flow study at the Roberts Road Pump Station.
As you know the proposed Deanna Estates 5 Lot Subdivision would be
tributary to this pump station.
It was clear to us that the capacity of the pump station may not be able to
take the additional flows and therefore a study would need to be
completed.
As per Mr. Tremper's memo of April 11, 2000, it is obvious that during
peak times (i.e. 7:00 a.m. to 9:00 a.m.) this station is at or near capacity.
If you look at the overall flow through the day, the station appears to have
excess capacity, but it is the peak times that are significant.
In conversations with Mr. Tremper, he has indicated that because there is
no holding vessel prior to this station that any excess flows during peak
times or any mechanical failures during these times would result in sewage
backing up into the lower homes that exist on Roberts Lane.
This coupled with the age of the station, lead to Mr. Tremper's
recommendation that an alternative solution be studied.

We have determined that there is a potential for a gravity connection from
Roberts Road into Rosewood Court that would allow for this pump station
to be abandoned. The savings in operation maintenance of the district
would be significant on a yearly basis and the return of the capital
investment would be realized in a short period of time.
I have enclosed a sketch of the proposed route of this sewer line. There
would be legal concerns that would need to be addressed as far as
easement acquisition, etc.; however the proposal is technically feasible.
I would recommend that a meeting be set up with the Town, the operators
of the sewage system, and the developer to discuss the potential of this
connection as it appears to be the best solution to serving this proposed
development's need for sewage collection.
I am taking the liberty of coping the Town Board and the Developer on this
memo and ask the Town Board that this matter be addressed at the next
available workshop.
If there are any questions, please do not hesitate to contact this office.

RE: Future Flows At The Roberts Road Pump Station
To help determine the existing flows at the Roberts Road Pump Station, CAMO
Pollution Control, Inc. installed a counter on the ejector at the station.
As you are aware, this is not a typical pump station. It is referred to as an
air ejector station, and the counter counts the number of times the lower pot is
blown with air. Assuming that the station blows at full pressure, the estimated
volume per ejection is 100 gallons. However, if the station fires off several times
during peak periods, it can be less than 100 gallons per pot.
The attached pages show the number of ejections and the flow, by date, since
March 15, 2000. I have also indicated the number of hours between each reading. In
addition to the existing readings, I also had the station monitored for a few days
during peak morning flow periods, between 7:00 a.m. and 9:00 a.m. It appears that
the station fired off, on average, approximately 25 times (2,500 gallons) during this
2-hour period.
As CAMO pollution Control, Inc. has previously mentioned, there are a number of
concerns at the station. CAMO Pollution Control, Inc. strongly recommends that, if
at all possible, this station be removed and the sewage gravity-flowed to another
location in the collection system, as opposed to making any improvements to the
existing station.
If you have further questions, please do not hesitate to contact me at (914)
463-7310.
