This Department 1S 1n the process of reviewing the State Operation and
Maintenance Aid Applications for the Town wastewater treatment plants.
This review process brings to light again the numerous problems that
exist at all these facilities. Since the Town no longer is a part of
Tri-Municipal, they must face the fact that these plants will be in
existence for some time and a program for improved operation and mainten-
ance and rehabilitation must be established. Accordingly, the Town must
submit to this office prior to September 1, 1984 an Engineer's Report
evaluating and providing a detailed program of rectification for a minimum
of the following items:
Oakwood Knolls S.D.
1) High flows; frequent bypassing and overflowing tanks.
2) The inadequacy of the rapid sand filter units. These units
must be made reliable on a continuous basis.
Wildwood S.D.
1) High flows at the plant.
2) Facility deterioration as a result of age.
Royal Ridge S.D.
1) High flows at the plant.

2) A total rebuilding of the sand filters to be completed by
the end of 1984 i.e.:
a) removal of old sand; inspection and replacement of
underdrains, if necessary;
b) new sand;
c) replacement of perimeter walls;
d) new distributors.
3) Rebuilding of settling tank to improve skimming and eliminate
short circuiting.
4) Improved disinfection to ensure continuous compliance with
SPDES Discharge Permit.
Rockingham Farms S.D.
1) High flows at the plant. of particular concern is the fact
that average daily flows are above the design capacity of the
plant.
2) Modifications to the disinfection system to ensure continuous
compliance with the SPDES discharge limits for co1iforms. The
utilization of a larger contact tank during sand filter bypass
must also be considered on a temporary basis. On a long-term
basis, these filters must be used continuously.
Fleetwood Manor S.D.
1) Reduction of flows.
2) Installation of approved backflow preventer on potable
water supply line.
3) Rebuilding of both settling tanks including weirs, etc.
4) Progress report on revamping the influent structure and
installation of bar screen.

5) Progress report on installation of flow meter.
6) Progress report on security patrol.
Because of the Town's past inclusion in the Tri-Municipal Project, this
Department has been extremely patient with regard to these facilities.
We have tried to cooperate so that funds were not spent on facilities soon
to be abandoned. The result has been a "band aid" approach and a further
deterioration of already disgraceful conditions. Please be assured that
this must now end and vie are prepared to take whatever actions are necessary
to improve these plants and protect the water quality in the Town of Wappinger.
