Application For New Well No. 10
GRPT 87-01
System
Gentlemen:
The engineering report and application was authorized
by the Village of Greenport on April 9, 1987. The purpose
is to request authority to develop a new well supply within
the Village of Greenport where water from the area has been
a problem for many years. The proposed well is on the east
side of Moore'· Land in the north edge of the McCann Trailer
Park property of the Village of Oreenport. The well is
proposed at approximately 1600 feet south of the North Road
where existing plant and well field ~3 of the Village is
situated at the southwest corner of North Road and Moore's
Lane. The existing test well constructed in 1985 is on
private property about 25 feet north of the Village-McCann
Park property line. The Village boundary line is the north
line of the McCann Trailer Park. The "Costello" property
has been the subject of development including possible
annexation by the Village for about two years and is
expected to be developed soon.
Test Well Details
· The test well was constructed in 1985 by Joseph Kreiger
Inc, a well drilling contractor, for Mr. John Constello,
owner of the 42 acre parcel. The test well is reportedly
constructed by the cable tool method, to a depth of 57 feet
below land surface. Ground surface elevation is
approximately 12 feet above mean sea level. The well casing
diameter is 5 inches and is 47 feet long. The well screen
is 5" in diameter and 10 feet 1on8 and is constructed of
stainless steel with a 'slot opening to suit the sand
formation ·creened.

Plant 3 is at the southwest corner of Moore's Lane and
North Road and consists of three (3) active wells. (north
· suction) and three (3) inactive (south suction) wells. Well
depths reportedly are 45 to 57 feet. The capacity of this
plant is about 340 gallons per minute. For many years, when
6 wells were in service and pumping capacity was greater,
the well field was flooded by vumein= from the Vi~ge
~eservoir during of -
-- period heavy use. This minimized the
increase in chloride levels, which at times exceeded the
· recommended drinking water standards. Water cualit? from
this plant is poor, ¥~rv
o~ the site is heavil wo
y oded which reduces net recharge to
the aquifer. This plant is a prime location to induce
treated water from the Silver Lake/Reservoir system to
increase the available capacity. This has been discussed
more extensively in alternatives for added supply.
Geology information in this area of the Village is not
complete, but from data available there are thick, tough
clays south and west of Plant 3. Apparently, north, east
and southeast there is more sandy material to clay at depths
of about 60 feet.
Some years ago, test borings conducted adjacent and
south of Plant 3 included a test well adjacent to the pump
house. The boring indicated two (2) possible substrata less
than 60 feet deep but a test well in the south suction to
the shallower depth was non-productive. This should be
repeated in the northerly section for hopefully better
results.'
~lant No. 4 is situated in the western edge of East
Marion Just east of the Island End Golf Course, east of
Greenport Village boundary. There are three (3) wells on
this 15.4 acre site, Nos. 4-6, 4-7 ahd 4-8. The wells are
about 80 2-e~t deep and have capacities of 150 to 260 gallons
per minute. Ail are powered by manually started diesel
engines since no electric power has been installed on this
site. Water quality at this loca~l n~as fluctuated wit
su~bstanti~l increase in chlorides and pest--des
so_~me nitrates. Pesticides in well 4-7 has reSulted i~ a
granulated activated carbon unit in operation ia 1986.

Nitrates have ranged from $ to 8 mg/1 of N for many years
in Wells 4-6 and 4-7 and 2 to 5 mg/1 in Well 4-8. Chlorides
have been rather erratic in Well 4-8 from 60 to mbre than
180 mg/1, while Well 4-6 has ranged from 60 to 170 mg/1.
Well No 4-7 has had a narrower range of 45 to 85 mg/1. Well
.4-8 has been relatively free of pesticides, while 4-6 has
shown as much as 11 mg/1, but an average of about 4 mg/1 for
much of 1985 and well 4-7 went over the limit in 1986.
Wells 4-6 and 4-7 are old wells and are subject to more
frequent mechanical problems. Even well 4-8 is about 30
years old. All three (3) well pumps, engines and
chlorination equipment are each housed in a one-story small
masonry building. An interconnection exists at the plant
with the adjacent Island End Golf Club which has a large
irrigation well (400 plus gpm).
The age of this plant is obvious. Recently, none of
these wells were usable for various reasons. Well 4-6
developed severe air entrainment problems and could not be
used until the cause was determined and corrected by
replacing the pumping units. No. 4-7 was rehabilitated and
shortly after return to service it develoPe~Cessi-Ve

engine problems for some time and is now equipped with a new
engine..
Plant No. 5 was the original pumping station of the
North Fork Water Company, which was acquired in the early
1960ts by the ¥illage. Four of the original 5 wells-are no
longer used, but well 5-5 still can produce at about 150 to
200 gallons per minute. The plant also contains the original
hydropneumatic tanks which extend through the west wall of
the below ground pump£ng station building. The site is L
shaped on South Harbor Road in southwest Southold Hamlet and
consist of 1.4 acres. This plant ~s in the most westerly
end of the water distribution system. The pumping station
structure is primarily below grade and has a large floor
area i£ needed for future facilities. For a few years it
b~t tests in 1986 on various wells a~d recent analy~or
w~ll 5-5 has caused this plant to be inoperative,

(No. 6~1) was a good producar, but Well 6-2 was later very
disappointing. W~thin 2 years, its capacity was reduced
from 500 to 350 gallons per minute and since then was surged

As noted in Table 2, the sustained capacity of the
existing Village sources of supply, prior to the deduction
0£ wells 6,3, with recommended deductions for reserve is
1645 gallons per minute or 2.37 million gallons per day.
If 6-3 is removed from the system the capacity ts reduced to
1155 g.p.m, or 1.66 m.g.d. This compares with a recent peak
day in 1986 of 2.10 million gallons per day and a current
P°tential Peak day of about 2.38, based on 900 gallons per
day per service and 2,640 services. ~__t has become more.

STORAGE FACILITIES
Storage fac%lities on the Greenport System consist of
one major unit, a 300,000 gallon elevated s~eel tank and two
(2) obsolete 15,000 gailon hyropneumatic tanks.
The 300,000 gallon elevated tank is on the west side of
Moore's Lane north of Route 25 in the Village of Greenport.
The tank overflow which controls 'the basic hydraulic
gradient in the distribution system is at elevation 185 feet
above sea level and has a range of water leve~ of 40 feet.
This tank is more ~han 40 years old, but because of routine
maintenance is in satisfactory conditioq. A future elevated
tank addition in Southold should be funded when appropriate
and should be in the near future.

Based on a normal storage of 20 percent or more of the
maximum day pumpage, where wells ere available Just for the
maximum day rate, more storage is now needed. A review of
the charts for the Summer off 1985 indiciates that the lowest
the tank reached on any day was a drop to 13 feet or to a
point of about 25 percent capacity remaining. Pumpage rates
for each hour are not available in the Creenport system so a
mass diagram type drawing or calculation cannot be made to
determine the actual amount which would have been used if
only the maximum day average rate had been available for the
full 24 hours. It is COmmon in most systems to have excess
well capacity and to actually use less storage than
theoretically required.
The two (2) 15,000 gallon hydropneumatic tanks are
located at Plant 5 on South Narbor Road in Southold. Under
normal pressure variations of about 10 psi, these tanks only
contribute about 2,000 gallons of Water storage. These
tanks are very old., dating back to the North Fork Water
Company days and should not be considered available for a
long term.
Elevated storage not only provides a system with water
during the hours when demand exceeds well pumpage, but it
also serves as a pressure regulator and surge suppressor and
provides a reserve volume for fighting a fire or for supply
during a power failure period until auxiliary engines can be
activated.
Looking to the future, we 'anticipate the need for
another tank of 300,000 to 500,000 gallons capacity.
should be placed on the highest available ground to minimize
costs, but more import~ntly, it must be at a politically
acceptable esthetic location and should be near transmission
mains. At this time, a best compromise site would be at
Plant No. 6 north'of Well No. 6-1, even though this does not
make the best uae of'transmission mains. Until the existing
tank is deteriorated and/or water treatment additive costs
becomes excessive, to date it has been more cost effective
to construct more shallow well capacity than to construct
more storage. ~t is.now time to think of added Storage so
good quality wells can be used more extensively and well
withdrawals spaced out. Even ground Storage may be
Considered to reduce treatment equipment capital costs but
not before a second elevated tank is Constructed.

Looking to a near future period
pumpage may reach 3.0 m.g~d.,total

planned and implemented in
It has been 22 years since a major drought imposed
excessive demands on most Water sys'tems of Long Island.
Greenport did not s~ffer as much as some others but even so
the demands increased about 50 percent with only a 20
percent increase in number of services. We'have t~bul'ated
tho "Water Use Data and Estimated" as Table 3 for 1947 to
1986 and estimated for 1990/1995 and 2000. The number of
services at the end of 1986 was 2,619 with about 2/3 of
these outside the corporate limits. The estimated
population served is 8,400 and growing. The average day
pumpage was 0.94 million gallons per day. The ~ximum day
(24' hours) during the summer of 1986 was 2.10 million
gallons' per day, which was lower than previously reported
for the years 1978 to 1983 and about equal to 1982 and 1983.
In order to meet a 2.7 million gallons per day
requirement, the Village should have rated well capacity
totaling about 4,8 million gallons per day to allow. for at
least one (probably two) 500 gpm, one 250 gpm and one 210
gpm unit or 1460 gpm out of service, These total 43 percent.
The needs for peak hour dome'stic use not handled by the
wells is supplied by'the storage t~n~. PEak ~our'demands
for fire protection actually exceed those for the domestic
system ~nd are suppgsed' to be available' coincident with the

duration fire ~emand is satisfied fro~ ~he Storage tank.
In order to have 4.8 (3331 gpm) million gallons per day
(mgd) usable weli capacity, at least'~n additional 730
gallon per minute (1.05 mgd) capacity should be provided
for immediately. (Also 2.71-1.66 . 1.05 mgd . 730 gpm) As
the system ages, and soon, added capacity should be provided
so that the ability to serve is comfortable instead of

Assuming the successful completion of well 9 at 200
gpm, the approval and implementation of the Costello well at
250 gpm; there is still the need for 2 more similar wells or
one larger well to restore reliable capacity to the needs of
the system.
The increase from 2.1 mgd needs in 1986 to the 2.7 mgd
predicted for 1990 will not be in even increments.
Actually, the Village system should be prepared to supply a
maximum day of 2.34 mgd in 1987, dependent on weather
conditions.
~ATER SUPPLY ALTERNATIVEM
None of the above addressses the water needs for fire
protection. Even though it is not expected that a fire will
occur on the maximum domestic day some reserves should be
planned for fire needs on those days. It is more
appropriate in the Greenport situation to provide this in
the 'storage tanks which should be planned soon. 'Reference
is made to the Master Plan and Quality Report for status of
fire flow conditions throughout the Greenport system.
Reference is made to prior reports for water supply
alternatives. The sources of good quality are still sitting
in the large lakes or ponds. Water nitrate quality
elsewhere is naturally improving, but slowly, in many areas.
Recommendation
For an extended time we have recommended acquisition of
small capacity new well sites in the area of Greenport that
we did not previously believe had a good potential for
supply. The test well' performed for Costello by others for
example show that good quality water is available at the
Village edge. This area is situated between 2 lakes or!
ponds so should have good recharge. Existing water sources[I
in most directions have shown high concentrations of ironl/
and manganese but the McCann Park/Costello area appears toil
be an exception. It is of course possible that in time and][
after extensive permanent well use. the quality found in thel[
sources will begin to show uphere but the tests to date do~]
not indicate a problem.

It is recommended that approval be sought for a
capacity of 250 g.p.m, either from the existing Costello
well or from a new well constructed about 50'feet south of
the Costello well. This plant would be designated Plan[ 10.
Plant 10 ReCommendations
As previously stated the proposed 250 g.p.m, capacity
approval would be obtained from either a new well to be
constructed on the ¥illage of Greenport property or from the
existing Costello well some 50 feet northerly, The new well
would be constructed wi~~-~ 8 inch casing and 10
feet of 6" stainless steel screen. In either case it is
proposed ~hat a more cost effective pumping system be
installed to take suction from the well with a self priming
centrifugal pump driven by a 20 HP horizontal electric
motor. A foot valve in the pump suction line and an
automa~ic water priming 'connection would be provided.
Treatment would by hypochlorite with future provision for
caustic or soda ash added treatment for pH adjustment.
The well pump, electrical and treatment equipment would
be housed in a one story small prefab type metal or wooden
structure. The water from the well would be metered with a
propelled totallizing type meter in the piping within the
pump station.
Water would be delivered to the existing l0 inch main
on Moore's Lane which in turn is connected to the nearby
300,000 gallon storage tank.
The estimated cost of this project is $125,'000 as shown
on Exhibit I.
The plant could begi~ operation within 9 months.
