STAFFING AND TRAINING
A Fishers Island Sewer District (FISD) has been established and
will serve as a central body of control for the new treatment
facility. A firm will be contracted to act as Superintendent. The
Superintendent will represent the FISD and serve ss Chief Operator
of the treatment facility. The Superintendent will be responsible
for periodic maintenance of the facility as scheduled by the
Operations and Maintenance Manual (0 & M Manual), end will be on
call for twenty-four (24) hour emergency service. The Gada Construc-
tion Co. will be hired to act as Superintendent.
In order to assure adequate time for familiarization with the new
facility and to adequately prepare for start-up procedures, the
Superintendent will be required to be hired on or before the fifty
(50%) percent completion date. TraininR will consist of a briefing
of the Superintendent on the functions of each particular unit of
the treatment facility. Because the Superintendent will be hired
prior to completion of the project, training will include field
visits to inspect the construction of each unit of the facility,
paying particular attention to the control and safety features of
each unit. The Superintendent should also become familiar with
each section of the Plan of Operation and the 0 & M Manual.

ADMINISTRATION
The size of the sewaRe treatment facility does not lend itself to
maintainin~ a full time office or administration. Therefore,
administration of the wastewater treatment facility will be per-
formed by the firm actin~ as Superintendent.
The duties to be performed by the administration are described in
Section 2 of the 0 & M Manual. The responsibilities associated with
these tasks will lie with the Gada Construction Co. and the FISD as
defined in Section 1 and Section 2 of the 0 & M manual.
EMERGENCY OPERATION
Due to the size and type of this sewage disposal facility, the
system is not expected to have major operating problems. SafeRuards
such as hiRh level and low level water alarms and a standby
Renerator are provided at the pump station and adjustable wier
gates are provided at the septic tanks and distribution boxes. A
more specific discussion of the emergency operation is presented in
Section 4 of the 0 & M Manual.
OPERATION AND MAINTENANCE MANUAL
The 0 & M Manual should be formulated according to
schedule:
a) Drafted December 15, 1985
b) Final September, 1986
c) Approved September, 1986
d) Updated based on
past year's
experience May, 1987

OPERATIONS BUDGET
This facility is scheduled to be~in operation in May, 1986. The
hirinR and training of personnel should begin by December, 1985.
Money for this pre-operation budget and start-up budRet has been
provided by the Fishers Island Development Corporation (FIDC0).
FIDCO has also paid for the Town's share of the construction cost.
The State of New York contributed seven and a half (7.5%) percent
and a federal Rrant financed the remaininR eiRhtv-five (85%)
percent of the construction cost.
FIDCO will be reimbursed for its initial costs by monev collected
from the system users by the ¥ISD after operation of the facility
has begun. This money will be collected in the form of sewer rents
imposed on the user by the FISD. In addition to coverinR the
initial costs, the rent will be collected to pay for operation and
maintenance costs incurred over the life of the facility, includinR
administration, repairs, parts replacement, utilities, trainin~ and
maintenance fees.The operating budRet should be updated annuallv
to maintain adequate funding and sewer rents should be changed in
an equitable fashion to the users. A detailed summary of the Total
Annual Operation and Maintenance Costs is found on pa~es 10 and 11.

A. ET~CTRICAL (See computation below) = $ 850.00
B. OIL (2gph x 1/2 hr x 52 weeks
+ 30 hfs) x $1.75/gal. = 143.50
C. PHONE (ALARMS) $32/mo. x 12 mos. = 384.00
D. SEPTAGE PUMPING once/3 year x 30,000 gal. -
2,500 gal/.load x $200/load = 800.00
E. ANTI-FREEZE 2 gal/year x $5/gal = 10.00
F. OIL & FILTER $25/each x I/year = 25.00
G. AIR FILTER $25/each x I/year 25.00
H. CLEAN WET WELL 4 times/year x $60 240.00
I. MISCELLANEOUS = ~ 150.OO
TOTAL ANNUAL OPERATION COST = $2,627.00
ELECTRICAL = is weighted to include decreasing rate structure and demand
charge.
DETERMINE: ELECTRICAL ENERGY COSTS

TDH = 40 feet
Input per certified pump curve = 3.75 KW
Eff. = 0.85
Pump Capacity = 180 gpm

12-300 kwhr = O.1517/kw
300 kwhr + = $O.1122/kwhr
Demand = $10.54/mo.
MONTHY COST ESTIMATE
kwhr/month = 20,000 ~al/day = 111.11 min./day = 1.85 hr/day + 1 hr allowance*
180 gpm
2.85 hr/day - 0.85 eff. = 3.35 hr/day x 3.75 kw = 12.56 kwhr/day
12.56 kwhr/day x 30 day/mo. = 376.8 kwhr/mo (say 377)
= $4.82 + 288 kwhr x $.1517/kwhr + 77 X $0.112/kwhr =
$4.82 + $43.69 + $8.62 + $10.54 = $67.70/mo.
