Proposed Water Well
I have enclosed material with reference to the Proposed Water ��.'ell that has
been presented to the City Council. I have attached the Engineer's Report
which shows the need for an additional water well. Our financial adviser has
prepared a financial schedule for this proposed water well. I have enclosed
copies of our outstanding Bond Indebtedness and payment schedule.
This Board has been requested to study and make recommendations to the
City Council for the October 7th City Council Meeting regarding the
proposed Water Well Project.
If the Board needs to meet more than this one ( 1) meeting regarding this
matter, we will have time to meet the week of September 23rd or the week
of September 30th.

T�J: Honorable Mayoz• &Members of the City Council
FROMP John Hamilton, City Manager
DATE: August 2, 1991
SUBJECT: Water Well Cost Estimates & Engineer's P.eport
The attached material was prepared by our consulting engineers for vour
review concerning the possibility of drilling an additional water well.
The Upper Trinity Water District. is currently at a stanrlstill as the City of
Denton, the 51% player in the proposed water treatment plant at Lake Ray
Roberts, has yet to sign a contract with the water district. I still believe the
project will be built, but around 1996, I also still believe it is the best
solution to our long term water needs and we should still be an active
participant in the project Our current contract calls for 1,000,000 gallons
of treated water daily (694 gallons per minute).
Additionally, Mayor Armstrong and I have contacted our financial (Bond
Company) advisor for any advice on available options for financing the
proposed water well.
After yot.t have had tune to review the material, it is scheduled for Council
discussion on August .19th.

Re: Water Implementation Plan
Alternative Supply for�sanger, Pilot Point,
and Mustang Water Supply Corporation
Dear Mr. Taylor:
We have assembled data concerning several alternatives for the
District to consider in suppling water to District customers of
Sanger, Pilot Point and Mustang Water Supply Corporation, as
authorized by the Board of Directors on May 2, 1991.
This study considers the supply of water from the City of Denton�s
system, or from a• temporary water supply source developed from
ground water wells to be located at the future water treatment
plant site at Lake Ray Roberts.
We have reviewed the existing supply capabilities of the three (3)
water customers and their project demands for the next ten (l0)
year period.
Based on information furnished from the District, the use of a
fifty percent (50�) participation by the Texas Water�Development
Board (TWDB) has been assumed for the option of water supply from
the future water .treatment plant site on F.M. 455. The option of
extending a water supply line from the City of Denton north along
IN-35 does not provide the opportunity for participation or sharing
of funds by the Texas Water Development Board.
02
�� The cost of this project would result in an annual debt
service requirement for bonds issued at eight percent (8�)
� interest for twenty (20) years, to be (101.86 x 1,234.) _
$ 125,695 per year.
3. The Plan B .concept of developing the basic water supply
pipeline with a temporary water supply well to serve water to
Sanger, Pilnt Point, and Mustang WSC on an interim basis is
recommended. The details of this plan would include the
construction of the District water supply pipeline for Sanger
to the Water Treatment Plant Site at Lake Ray Roberts and the
construction of a small District pump station, ground storage
• tank and water well. The second part of Plan B would be to
construct the District water supply pipeline from the water
treatment plant site east to serve the City of Pilot Point and
I the Mustang WSC.'
The Plan B scope of work .could be considered in a two stage
project. The Sanger water line with a temporary water well,
etc. is a first phase item followed by the Pilot Point /
Mustang WSC water -line. The projected savings on Plan B would
result due to the possible delay in the water treatment plant
construction; possibly by up to two (2) years. In order to
achieve the two (2) year delay, the use of a temporary water
supply well, etc. is required. The savings in debt service
cost achieved by the delay in construction of the water plant
does exceed the total projected cost of the first water well,
storage tank, pump station, etc. The projected construction
cost of the temporary water supply facilities is $ 623,000
while the annual debt payment for the water plant facilities
is $ 778,210. The difference in $ 778,210 and $ 623,000 does
show that the cost of the temporary water supply facilities
would be offset with just one (1) year of delay in debt
payment.

■
IF m
Based upon an analysis of the data, we recommend the Upper Trinity
Regional Water District should give immediate attention to the
following:
IA) Proceed with the joint agreement for construction of the water
I treatment plant so that the new water treatment plant can be
placed in service prior to 1996. Data indicates that either
Ithe new water plant should be available for production of
water, or the development of possibly up to three (3) water
wells will be required.
B) Proceed with the engineering design of .-the various water
facilities based upon the best available data in order to have
construction plans ready for bidding and construction purposes
when required.
C) Proceed with the development of Right -of -Way and Easement
documents for the proposed• pipeline construction. This would
also include the acquisition of easements for the various
pipelines. - d•
D) Proceed with. the installation of a water pipeline between
Sanger and the identified plant site (temporary water well
site) for use prior to the Spring of 1993. This will require
the construction of a water well.
E) Proceed with the installation of the water pipeline between
Pilot Point and Mustang Water Supply Corporation and the
identified plant site (temporary water well site) for use
prior to the Spring of 1996. -
F) Continue the District's efforts to develop a good, reliable,
and safe system that can provide service to all of the
District member customers with an adequate water supply at an
economical rate.

GENERAL
The Scope of Study is to investigate and consider the alternatives
for serving the City of Sanger, the Mustang Water Supply Corporation
(MWSC) and the City of Pilot Point, Texas.
The alternatives given consideration are as follows:
PLAN A. District to construct a water line along IH-35 from the
City of Denton north to supplement. the City of Sanger�s
system.
PLAN B. District to develop a ground water well at 'the future
water treatment plant site at Lake Ray Roberts and proceed
with the construction of the supply lines to Sanger and
Pilot Point / Mustang Water Supply Corporation.
The data has been developed for each of the various alternatives
outlined for this study. A cost benefit for each is also developed.
The locations of Sanger, Pilot Point and Mustang Water Supply
Corporation are shown in Figure 1, relative to each other and
relative to the identified site for the City of Denton and the Upper
Trinity Regional Water District water treatment site located
immediately below. the dam creating Lake Ray Roberts adjacent to
F.M. 455 just west of the Elm Fork of the Trinity River.

SUKPACE WATER SUPPLY
The District has previously given
consideration to joint ;I
participation with the City of Denton in the construction of a water
treatment plant to be located at the identified plant site at Lake
Ray Roberts. bue to the existing availability of surplus water
within the City of Denton according to the information furnished the
District, the previously scheduled construction of the water
treatment facility will be delayed for a period of years.
Therefore, to fulfill the District's commitment for providing water
to Sanger, Pilot .Point,and the Mustang W.5.C. several alternatives
must be investigated to arrive at a program and plan for providing
tThbt waer. e es. cost benefit for the District should be given
consideration. In short, the cost benefit for each party to the
project must be given careful consideration and study. The
individual water customers are the final parties who will be paying
the cost to retire the debt structure and at the same time support
the financial commitment necessary to develop, construct and
maintain the water supply facilities.
In order to evaluate the needs for the three water customers of the
Qistrict, a review has been made of the existing production
capabilities along with the projection for water requirements to the
year 2010.
The data p
wresented in this report was gathered directly from the
ater departments of Sanger, Pilot Point and the Mustang Water
Supply Corporation.

GROUND WATi✓R SUI'PLICS
The use of ground water supplies is a short term option for
consideration by the District. A review of the geological formation
within the area of Sanger, Pilot Point and the Mustang Water Supply �i
Corporation identifies that the Twin Mountain Formation overlies
throughout the study region. This is the lower, member of the Trinity ii
Group and was formerly called the Travis Peak Formation. �
The Twin Mountain sequence in north central Texas consists mainly of �'
medium to coarse grained sand, red and gray silty clay, and siliceous
conglomerates of chert, quartzite and quartz pebbles. The Twin Mountain
formation is the most, important source of ground water for this study
region and yields moderate to large quantities of fresh to slightly
saline water for municipal use.
Yields of wells completed in tl�e Twin Mountain Formation range from 10
to 1,940 gallons per minute, with a calculated average yield of 286
gallons per minute. Wells within the Denton County area average about
300 gallons per minute. The specific capacities of the wells developed
in the Twin Mountain Formation range e�ith an average of 3.3 gallons per
minute per foot of formation.
Generally the net sand thickness of the formation is up to 190 feet in
the Denton County area. The records of existing wells drilled into the
formation identify the- depth oL- the well ranges from 1, 283 to 1, 352 feet
below the surface. �
The formation and water strata should be available for the development
of a well to a projected depth of around 1,450 feet. The anticipated
capacity of a well with these general conditions would be around 300
gallons per minute or 432,000 gallons per day.

The existing water system extends to the intersection of Ili-35 at
I) Business Highway 77. This is an existing eight inch (811) line which is 1
a dead end line served as a stub from the University Drive area. A I{
short section of twelve inch (1211) line has been constructed to the
Camper World site.
i
The reported static pressure at the north end of this line is around 50 !!
p.s.i. The ground elevation is approximately 695 feet m.s.l. The '
hydraulic grade line is approximately 798 feet m.s.l.

If the City of Denton did furnish water for the Sanger system, it will I'
!� be necessary for a looped line to be extended south along IH-35 to
connect into an existing eight inch (811) line located on the west side ;+
of IH-35 approximately 4,000 feet north of U.S. Highway 380.
The length of the line between the Sanger water system at Loop 138 and
the Denton system at Business 141ghway 77 is 31,600 feet.
The profile of this .water line along IH-35 would start at ground
elevation 695 passing through a high elevation of 705 and 710 crossing
Clear Creek at elevation 590 and back up to a terminal elevation of
around 690 feet.
A review of the system operation would show that the use of eight inch
(811) pipe would have a friction loss of 24 p.s.i. at a flow rate around
300 gallons per minute (09432 mgd). The anticipated pressure loss due
to friction for a twelve inch (1211) line flowing 500 gallons per minute
would be 8 p.s.i. while the same twelve inch (1211) line flowing at 700
gpm (1.008 mgd) would sustain a pressure loss of 15 p.s.i.

The cost of Right-o£-Way Easements is included in this data. The use
of the Highway Department Right -of -Way with a permit to be served for
Utility purposes may be considered for this line. The consideration of
this line is for a temporary supply line for the District. The long
term use and ownership of the line would be primarily for the City of
Denton to serve the future water customers along IH-35.

After a review oi' the available data and the best anticipated I
�i operating conditions, the delivery of treated water by the Upper
II
it
i Trinity Regional Water District to its customers should be at a
' pressure equal to the elevated tank level. If the customer does
I
elect to receive the UTRWD water at some lower pressure, then the
jj district should give consideration. The policy in the past has been
for the District to deliver water to its customers at a receiving
i
ground storage tank level.
The Pilot Point/Mustang WSC delivery point appears to be best
� I
I selected at a point where the ground elevation is around mean sea I
level 720 feet. An elevated storage tank constructed at this site
�! would allow delivery of water into the Pilot Point System through
i;
(� the Pilot Point feeder line. This tank site would also provide the
delivery of water through the Mustang WSC feeder line.
The UTRWD would benefit from the elevated tank at r.M. 455 and U.S.
Highway 37.7. The tank would allow for equalization of flow, and
allow for a uniform developing of water rather than at a peak rate
production. The storage reservoir will allow for future
consideration of delivery of water from the water treatment plant in
off-peak demand periods. Storage tanks will be required as a part
of the total system. The distribution of storage facilities into
customer base areas is more practical than having all facilities at
one location. Economy in design of pipe lines with possible added
capacity of size reduction will result when the line isnotused to
carry future peak demands. This reduction will be achieved in
filling storage tanks at a uniform rate over a 24 hour period.

The prior engineering reports identify the probability of delivery
of UTRWD water to Pilot Point direct into the City, with an
additional feeder line south back to the Mustang WSC. The placement
of a supply storage reservoir at F.M. 455 and U.S. 377 would
eliminate the duplicates or parallel of a line back to Mustang WSC.
The plan for an elevated storage tank at F.M. 455 and U.S. 377 is
practical and cost effective.
The analysis of .the Sanger, Pilot Point and Mustang WSC needs
indicate the following:
1) Sanger does need to receive supplemental water prior to
1993. The anticipated deficiency is real. The projected
requirement is for approximately 1.0 mgd by the year 1996.
2) Pilot Point does have an ample supply through the year
1993. However, prior to 1996, the probable need for
I
dditional supply will result. The projected requirement
is for 0.2 mgd by the year 1995 - 1996.
3) The Mustang WSC system reflects an ample available water
supply for the current needs. The water system does have
a hydraulic design condition which would create a major
shortage of water should their north well fail.
Therefore, the supplement of water from UTRWD is needed
for operational reliability and also to supplement the
projected future shortage. The needs for water will be
forecoming prior to 1996. For planning purposes,
consideration should be given for the water supply to be
made available on or prior to 1995.

In order to fulfill the water supply requirements, the U.T.R.W.D.
!� should give consideration to the following:

SUPPLEMENTAL WATER NEEDS 1993 1996

TOTAL 0.2 1.3
The projected water requirements for Sanger, Pilot Point and Mustang
WSC indicate that there is an urgent need for supplemental water for
Sanger within the next 15 to 18 months. The development of a water
well with supporting pipeline will satisfy the need.
With the requirements of Pilot Point, and Mustang WSC, there will be
a need for additional water beyond the capacity. produced by one (1)
well. The well site location should be identified for planning
purposes. Each water well should be no closer that one-half (1/2)
of a mile to each other. The Health Department will also require a
sanitary easement with a radius of 150 feet around each well site.
SCHEDULE OF SUPPLEMENTAL WATER SUPPLY SOURCES
PROBABLE PRODUCTION RANGE
1) 1993 Water Well 300 gpm 0.4 mgd
2) 1995 Water Well 300 gpm 0.8 mgd
3) 1996 Water Well 300 gpm 1.2 mgd
A typical well site with a small pump station and ground storage
tank will require about two (2) acres in area. The Health
Department does require the site to be fenced.
