MANUFACTURER'S OPERATION & MAINTENANCE MANUALS
SECTION 1 - INTRODUCTION
The purpose of this manual is to provide a format for the
operation and maintenance of the Fishers Island Wastewater Treatment
System. Proper use of this manual will result in a safe, effective,
and efficient sewage treatment facility. Therefore, it is important
for those involved with the facility to learn and understand the
guidelines and procedures set forth in this Manual.
The Fishers Island Sewage Disposal System is actually three (3)
separate systems. One services three (3) cottages on Reservoir Road
and consists of a septic tank and leaching pool system. Another
services a local cinema on Whistler Avenue and consists of a septic
tank and leaching gallery system. The third services the community
in the eastern part of the island and consists of three (3) septic
tanks and leaching gallery system. Each of the three (3) systems
will require maintenance but the community system will require the
most attention because the sewage in this system has to be pumped
to the treatment site.
All final decisions regarding the operation and maintenance of
these three (3) systems are the responsibility of the
Superintendent of the facility. The size of these systems does not
warrant a full time operator, therefore, Gada Construction
Co. will be hired as a Superintendent to operate and maintain the
facility as a representative of the Fishers Island Sewer District
(FISD). The Gada Construction Co. is required to have on staff a
person who is qualified to perform the duties described below.

SECTION 3 - DESCRIPTION, OPERATION, AND CONTROL - COMMUNITY SYSTEM
Sewage flows by gravity along existing sewers* from community
buildings to where the sewage outfall is located. The old outfall
hms been abandoned and a new pipe has bmen installed to carry the
flow by gravity along two hundred five (205') feet of pipe to a
wet well and pumping station located on Fox Lane. The sewage is
then pumped along a six (6") inch force main to the septic tanks
and leaching galleries located on Whistler Avenue. This system was
designed for a summer average flow of twenty thousand (20,000)
gallons per day (gpd) and a winter average flow of seven thousand
five hundred (7,500) gpd. The flow during the peak hour is
estimated to be eighty thousand (80,000) gpd.
The sewer use ordinance prohibits discharge of undesirable wastewater
to the system. Septage or chemical wastes shall not be dumped into the
system and all extraneous wastes from roof leaders, sump pumps and
catch basins shall be kept out of the system. Any of these kinds of
connections if identified should be removed. The sewer collection
system should be inspected and cleaned as necessary.This will involve
cleaning manholes and pipes of grease and grit at least on an annual
basis or more frequently as inspection would indicate.
The pump station is composed of a valve pit, an external back-up
generator, an underground fuel tank, a control panel, and a wet
well which contains the two (2) pumps.
The valve pit houses the pressure gauges and valves** used to monitor
and control the effluent from the pumps. A four (4') foot by four
(4') foot access hatch is provided for inspection and maintenance
purposes. These valves and gauges should be monitored occassionally
to determine if the pumps are operating as specified. In the event of
an emergency, the valves can be manipulated to accomodate by-pass
pumping with a portable pump.
The external generator is provided as a back-up in case of an
electrical power loss. The generator is a 33 kw Kohler generator
from GLT Industries, Inc.and is located just outside of the wet well.
The generator is activated when the automatic transfer switch senses
a loss of power. The transfer switch is a one hundred (100) amp
automatic switch from Kohler Industries and is mounted above
ground at the control panel. The switch should be checked monthly
and the generator should be checked according to the manufacturer's
maintenance procedures. The generator is presently programmed for
½ hour excersizing on Tuesday of each week which can be adjusted to a
* The old U.S. Army Base Sewerage System is still intact.
** Note: These check valves must be monitored to assure that they seat
properly i.e. the counter weight is very sensitive; if it is
mounted too far out on the arm, the valve will have trouble
opening; if the weight is too close, then the valve will not
seat properly and leakage will result.
4
different day if desired (see manufacturer's
event that the generator is in use for an
it should be checked more frequently.
instructions). In the
extended period of time,
The underground fuel tank is a five hundred fifty (550) gallon
fiberglass tank which is located near the stand-by generator. It
holds diesel fuel which is pumped by the fuel pump to the Day Tank.
From the Day Tank, a transfer pump sends the fuel at a controlled
rate to the back-up generator. The diesel fuel level and the fuel
pumps should be monitored and inspected monthly. In the event of a
declining fuel level, a leak should be suspected, the problem
should be investigated, and a remedy to the problem should be
implemented immediately. The generator engine is heated. However
the day tank is not heated. Therefore, the diesel oil should be
winterized . If the diesel oil is allowed to freeze and becomes more
viscous, this could clog up the internal workings of the generator.
The control panel serves as the central control system for the pump
station. It contains the transfer switch, a one hundred (100) amp
safety switch, twenty (20) amp circuit breakers, a three (3) KVA
transformer, and a red alarm light. From here, the sewage pumps
and fuel pumps, the alarm signals, the telephone alarm circuit, and
outdoor lighting can be controlled. The electric meter is on th~
telephone pole across the street. The records of the power usage for
the pump station should be maintained on a monthly basis in order to
monitor pump efficiency and the lapsed time meter should be checked
on a daily basis. An imbalance of hours usage when the system is in
the alterr~ing mode means a pump is not functioning properly. The
mercury column on the face of the panel shows the elevation of the
wastewater above the bottom of the wet-well. The key elevations are:
the elevation of the water level triggering the highwster level alarm,
the lead pump on, the la~ pump on, the lag pump off and the low water
level alarm. The elevations in the mercury column can be set in 3"
increments. The wire leads and increments are shown on the back of
the panel.
The wet well is the unit where the sewage is pumped from the eight
(8") inch gravity sanitary sewer to the six (6") inch force main.
The two (2) pumps in the wet well are four (4") inch,
non-clogging submersible pumps which run at one thousand seven
hundred fifty (1,750) revolutions per minute (rpm) and deliver one
hundred eighty (180) gpm against a total dynamic head of forty
(40') feet. The pumps are equipped with several safety features
which include a high temperature shutdown sensor with automatic
reset, a lightning arrestor, a moisture detection device to detect
seal failures, and a high water and low water sensor.

Water levels are sensed by an electro-gage from The Electromate
Corporation. The water levels are sensed by comparing the air
pressure exerted by an air compressor through a bubbler tube to the
water pressure created by a certain depth of water.The bubbler tube
can be purged through a port on the control panel.The port is a 1/4"
fitting onto which a portable compressor can be connected. The
compressor will then force air through the bubbler tube and clear
the tube of any debris. This purging process should be done once
every three months. The end of the tube in the wetwell should be
checked and cleaned of any buildup as necessary. There is also a
test port located on the control panel. By covering the test port
tightly the system will react as if the high water alarm went off.
This is a good test of the systems alarm system. As the water
level changes, signals are sent to the pump controls on the control
panel and the pumps are activated or deactivated as needed. If ~he
water level becomes too high or tho lnw, the high water mr lnw
water alarms are activated, the alarm horn will sound, the alarm
light will flash and the predesignated emergency telephone number
will be dialed to alert the Gada Construction Co. The high water
alarm is set to go off when the water level reaches an elevation of
1.00. The Iow water alarm is set for an elevation of -2.50.
The electrogage contains a blow down port which can be used by
the Superintendent to clean the bubbler tubes if necessary, and a
test port which can be used to check the accuracy of the sensing
device. The whole sensing device and alarm system described above
should be checked on a monthly basis or as the manufacturer's
operation procedures dictate. The pumps and pump motors should be
maintained regularly according to the manufacturer's operation and
maintenance schedule.
The quantity of sewage pumped through the system should be
determined on a monthly basis. The flow(Q) can be measured by the
drawdown method. This method is an indirect method by which the
flow is calculated by knowing the change in depth of the water
over a given time period. The procedure is as follows:
Observe the depth of the water in the wet well using the mercury
column on the control panel when the Dumps are off at time =
tO , in minutes, X1 in feet
With a stop watch, record the amount of time that passes until
the second observation is made.

7. Q Total = Q1 + Q2 in gpm
Where 211.49 is a conversion~factor to gpm accounting for wetwell
dimensions snd Q Total is the total flow passing through the pump.
The wet well is provided with an access hatch measuring two and a
half (2.5') feet by four (4') feet. Through the hatch, the pumps
and sensors can be maintained. If major repairs are necessary, the
pumps can be removed by using a tripod hoist over the access hatch.
The hoist will be stored in the valve pit when not in use. The
hoist has a twenty-five (25') foot deep reach and can lift up to
one (1) ton. The hook of the hoist can be connected to a chain
which is attached to the pump itself.
A key wrench will be needed to open the access hatch doors on the
wet well, valve pit, and the distribution box at the leaching field.
The same key wrench can be used for all the hatch doors -by
inserting the key in the flush lift handle, turning and lifting.
The key wrench will be kept with the Gads Construction Co.
The sewage is pumped by the pump station to the leaching system
where it is treated. The sewage first flows into a manhole where it
is directed into a distribution box. It is then distributed to
three (3) septic tanks which remove the settleable solid waste.
After leaving each of the septic tanks, the effluent goes through
three (3) distribution boxes and is directed to one (1) large
distribution box. From this distribution box, sewage is directed to
other distribution boxes and then to the leaching galleries. The
distribution boxes serve as a controlling feature to direct the
sewage to certain leaching fields. These leaching fields and
distribution boxes should be inspected on a semi-annual basis. The
Suffolk County Health Department will inspect the leaching fields
for loading periodically.The septic tanks should be inspected every
three (3) months. Should any maintenance be deemed necessary by Gada
Construction Co., the shear Rates in the distribution boxes may be
adjusted as needed to divert sewage away from the unit in question.
The scum layer in the tanks should not be allowed to build up to the
point where it drains into the leaching field.
Some problems that may be anticipated are:
(1)
(2)
Septic tanks becoming filled with sludge or floating scum. The
scum layer should be removed before it goes into the fields.
Distribution boxes becoming filled because of incomplete
settling from the septic tank;
(3) Distribution pipes become clogged; and
(4) The leaching galleries become clogged.
It is estimated that the septic tank sludge will have to be removed
every three (3) to five (5) years. The actual frequency will
be determined by the Gads Construction Co.. Cleaning will be super-
vised by the G ada Construction Co.. Septage disposal will be in m
solid waste disposal area as approved by the regulatory agency of
the place of disposal.
During the winter months, the population is less than during the
summer months and thus sewaRe flows will be less. In this situation,
the shear gates in the leachinR system can be adjusted so that
less than one hundred (100%) percent of the system will be used.
The actual percentsRe of the system that will be used will be
determined by the Superintendent based on the actual amount of
sewaRe flow during the winter months. One or two sets of galleries
may be used.

DESCRIPTION, OPERATION AND CONTROL - CINEMA
The sewage disposal system serving the cinema located on Whistler
Avenue treats only the sewaRe Renerated by the cinema. This system
consists of one (1) septic tank, one (1) distribution box, and twn
(2) gallery trenches. Gravity flow prevails throughout the system,
making operation of the system self-sufficient. However, the system
must be maintained on a regular basis. The septic tank is provided
with two (2) inspection covers. The leachin~ ~alleries are also
provided with two (2) inspection covers each. These units should be
inspected and maintained on the same schedule as that previously
described for the community system.
DESCRIPTION,
OPERATION AND CONTROL - THE COTTAGES SYSTEM
The subsurface sewage disposal system located on Reservoir Road
serves three (3) cottages. This system utilizes part of the old
sewerage to transport the sewage to the treatment system. The three
(3) cottages have sewer hook-ups to an old eiRht (8") inch cast
iron pipe. This pipe is then connected to a new eiRht (8") inch
ductile iron pipe which leads to one (1) septic tank. The septic
tank effluent then proceeds to four (4) leaching pools. The sewage
flows by gravity and thus would be self operating. Maintenance must
be provided to insure efficient treatment. A sanitary manhole 'is
provided at the junction of the eight (8") inch cast iron pipe and
the eight (8") inch ductile iron pipe. These manholes can be used
for inspection and cleaning of the pipes in the event flow becomes
blocked.The septic tank is provided with two (2) inspection covers.
Each leaching pool is also provided with an inspection cover. These
units should be monitored and maintained in the same fashion as the
community system ie. septage and scum should be removed to avoid
excessive build up.

SECTION 4 - EMERGENCY OPERATION
Although the Fishers Island Sewage Treatment Facility is a
relatively simple one, the benefits derived from it are great and
failure of the system could have far reaching effects. There are
several locations in the system in which failure could occur.
The pump station is the most vulnerable. The pump station could
fail if both pumps cease to operate because of mechanical
malfunction or if there is an electrical shortage and the stand-by
generator fails to activate. This type of failure could result in
backing up the pipes leading to the pump station. Odor problems and
possible health problems could result. This situation would
activate the high water alarm, a light and horn will sound at the
pump station and the Gada Construction Co. will be notified to
rectify the situation via automatic telecommunication lines.
Pumps will also be shut down by a self-monitoring mechanism if
the motor temperature becomes too high. This feature will
automatically reset when the motor temperature returns to safe
ranges.If the pumps remain idle for a long period of time, the high
water alarm will be activated and the situation can then be
corrected.
Another self-monitoring mechanism is a moisture detector which
senses moisture in the oil cavity of the pump motor should the
lower seal fail. The pump will shut down if the sensor detects
moisture, until it is manually reset. Again, the high water alarm
will signal attention to this problem. Another possible cause for
a high water alarm would be pump failure. A low water alarm will b~
sounded in the same manner as the high water alarm if the pumps
fail to shut off at their pre-designated times. The high water and
low water level alarms are an important warning system for the
pump station and maintenance as defined in the "Description,
Operation, and Control" secton of this manual and should not be
neglected.
The pipes leading to and from the pump station are another location
where problems could occur. If pipes clog before the pump station,
sewage will back up in the pipes and result in odor problems. Th~s
occurance would activate the low water level alarm at the pump
station before any significant problems result. A clog in the force
main leaving the pump station would result in the triggering of the
high water level alarm before any major problems occurred.
Pipe cracks or joint leaks could occur resulting in contamination
of the groundwater. Groundwater contamination is of concern because
most of the inhabitants of the island have, as a prime source of
their drinking water, wells that tap directly from the groundwater
supply. Detection of these types of failures are difficult. A
11
however, by odor problems,
or sandy deposits in the
major leak in the pipes can be detected
prolonged deficiencies in the flow rate
septage.
Another unit in the system susceptable to failure is the septic
tank. Leaks can cause the same problems as the leaks in pipes.
ARain, these leaks are difficult to detect but careful inspection
during cleaning and monitoring any decline in flow passing into the
leaching system can help. Weir gates in the distribution box
leading to the septic tanks can be used to stop flow from entering
into a specific septic tank for cleaning and inspection. This
operation would not cause an interruption of the entire system.
Septic tanks must be functioning properly to insure adequate
treatment in the leaching system. If the septic tank is not fu.lly
cleaned according to the schedule specified in the "Description,
Operation, and Control" section of this manual, solids in the
sewage will not be able to settle out and will clog the
distribution boxes and the leaching system resulting in uneven
distribution and inadequate sewage treatment.
Even distribution to the leaching system is essential to the sewage
disposal efficiency. Uneven distribution by the distribution boxes
can occur because of clogged pipes or incorrectly positioned weir
gates. Uneven distribution will mean a possible overload in the
leaching system and the result would be contaminated groundwater.
During start up the weirs and field loading have been adjusted to
be equal.
The gallery trenches in the community system and the cinema system
and the leaching pools in the cottages system are essential in
treating the septic tank effluent. Liquid sewage enters the
leaching system and filters through the underlying soil which
provides for aerobic treatment of the sewage. If a single trench
or pool becomes clogged or overloaded, it cannot function in the
way it was designed. Untreated sewage will then leach into the
s~il And c~ntaminate the ~roundwater.
If any unit in the disposal system fails or becomes ineffective and
is discovered either by alarm, or by inspection, the Gada Construc-
tion Co.will correct the problem immediately.
