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.

Taylor, General Manager - Upper Trinity Regional Water District Post Office Box 305 ��� Lewisville, Texas 75067 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. 023 '�\ NIMiERASSOCiAtES.INC. ■ 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.

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. it ��� � ` NUNTEq ASSOCIATES, INC. r 'IUF UKAIJHY The USGS topographic data for this area identifies the following relative elevations.

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.

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. 14 v� E �� NUNfE11ASSOC�AfES,iNC.J 14 0 The available chemical analysis of water from a well in the Twin Mountain Formation is as follows: CI-1 rivi CAL Aquifer Depth Silica (Si02) Iron (Fe) Calcium (Ca) Magnesium Sodium (Na) Potassium (K) Bicarbonate (HCO.1) Sulfate (SOO Chloride (Cl) Fluoride (F) Nitrate (NO3) Boron (B) Dissolved Solids Total Hardness as CaCO3 Specific Conductance Ph Percentage of Sodium Sodium Absorption.Ratio (SAR) Residual Sodium Carbonate (RSC) Altitude of Land Surfaces (msl) WELL No. 48-103 301 � KCTM KCTM 1283 1352 '! 10 14 6 1 !� 1 1 �� 277 206 373 368 I i 38 95 190 15 0.2 0.2 2.3 196 7p7 514 18 5 1,174 843 8.2 8.2 97 98 27.5 34.8 5.7 598 700 700 Based upon the best available data and review of reports prepared by the Texas Department of Water Resources$ the use and development of a ground water well would be possible at the identified plant site below Lake Ray Roberts adjacent to F.M. 455. 15 � t NUN�ER p550C1A1E5, INC. M r 1� PLAN A - DLNTON TO SANGER SUPPLEMENT 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. I; 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. .419 1G — - -- -' � : � HI1NiEq ASSaC1AtE5, INC JI ' �• 1 line is to be This pressure loss data will show that if a supply considered between the Denton system and the Sanger system, a twelve !! i; c 1 inch (12") minimum diameter pipe line should be considered as a minimum.

U53 � _ 2 0 - � � � NUNTER ASSOCIATES, INC M 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. 21- tr` NUNTppASSOCtATES.iNC.=' r \ 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. 1 055 �` HUNTER ASSOCIATES,INC.= In order to fulfill the water supply requirements, the U.T.R.W.D. !� should give consideration to the following: + Prior to Prior to SUPPLEMENTAL WATER NEEDS 1993 1996 1) SANGER 0.2 1.0 2) PILOT POINT 0.0 0.2 3) MUSTANG WSC 0.0 0.1 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.
