Financial Year 2004 Statistical Report • The City will implement a meter exchange program that provides for the annual replacement of meters in the system that do not register the correct amount of water flowing through them. This program will increase revenues and water accountability Funding for the meters will come from the amount allocated for infrastructure replacement. Meter replacement will take place as described below Meter Infrastructure Replacement 1 Identify and report active 3/4- and 1 inch meters that register less than 200 cubic feet of flow and active 1 '/2-inch or greater meters that register less than 1500 cubic feet of flow for three consecutive months. 2. Compare the meter-reading report with the flow report to determine which meters appear to be functioning improperly 3 After all valid reasons for low flow at a location have been identified, the remainder can be assumed to be non-functioning and can be scheduled for replacement. City of Fort Worth Water Conservation Plan 2005 1-T ~OTAC 1 4 S stem Water Audit Non-Revenue or Unaccounted-For Water BMPI 1, ~as.z(a)0)(r> y ~ ~ ~~ Fort Worth has conducted the first International Water Association (IWA) standard water audit in the state of Texas. The system water audit is the overall figure that can be used to monitor the total level of non- revenue water in the system. It is a complex and difficult task. There are many variables which influence the revenue and non-revenue components of Fort Worth's water system. The audit involves many of the Water Department divisions, including Engineering, Customer Services, and Operations. It evaluates the marginal costs (purchase of water from TRWD as well as treatment and distribution costs) and costs of service, so that the analyses have sound figures with which to develop the cost-benefit scenarios. The City conducts this audit annually 1.4.1 Real Losses Real losses are direct losses from the system through leakage from the infrastructure and overflows out of the system. 1 4.2 Apparent Losses Apparent losses are paper losses which result from meter error, billing errors, illegal use, and other unbilled uses such as Fire Department. 1 4.3 Indicators of Performance In the past, indicators of water system performance have generally been poor and incomplete. Most systems currently use only the percent-unaccounted-for water method to analyze their efficiency This is not a good performance indicator The City has developed internal regulations and targets which match and exceed the new standards required by the TCEQ and proposed by the TWDB Even more importantly the performance indicator approach provides an internal accountability for specific water system tasks which will improve the performance and efficiency of the system in the long-term. The audit and its associated performance indicators will be integrated into the City's conservation plan. The plan will be updated on a regular basis with specific portions such as the targets and goals being updated every year so that all the operational departments can begin to assess their water supply performance in a more quantitative way 30 TAC ~BMP 7 171 zss.z(axlx~> 1 5 Public Education and Information ~ In addition to its existing efforts to educate the public with both water bill inserts and educational events promoting water conservation, the City has plans to establish a Customer Advisory Committee to include representation from a spectrum of customer classes and City departments. The goal of the committee will be to promote community awareness of the City's plans. The City currently provides education programs for grades 3 through 5 in schools within the Fort Worth Independent School District. The programs incorporate the following themes Waterama for 3rd Grade, Major Rivers for 4th Grade, and Waterwise for 5th Grade. The program is intended to increase use of these curricula not only among Fort Worth ISD schools but also among the 13 other school districts which City of Fort Worth Water Conservation Plan 2005 1-8 operate within Fort Worth's city limits in addition to all the school districts within the wholesale customer boundaries. It is intended that the program be incorporated regionally through interaction with the Tarrant Regional Water District and that large wholesale customers develop cost-effective public education programs. The City will also form a Customer Advisory Committee to discuss, assess and provide direction for the conservation programs outlined in this document. The committee will include residential, commercial, industrial, institutional, imgators, wholesale customers, and any other interested customers. 30TAC 1 6 Water Rate Structure 288.2(a)(1)(H) BMP 2 288.2(a)(3)(A) The City of Fort Worth has existing, conservation-oriented water rate structures in place. The City continues to refine rate structures to improve their effect on water conservation and to manage cost of service more effectively This is done by analyzing the trends of use by customer class and associating increases in rates proportionally to those classes which place the most demands upon the water system. In the next five years, the City will conduct additional assessment and consider increasing tiers for the Commercial Class. The City is also performing detailed analyses of Industrial and Irrigation users to consider nonpromotional conservation rates to match those groups usage characteristics. 1 6.1 Current Rate Structures The City's current rate structure consists of the following four categories. Residential Commercial Industrial Irrigation Each customer is assessed a meter charge based on meter size. There is an additional usage charge. The rates adopted and implemented effective January 2005 for the Residential customer class include a conservation rate structure. Fort Worth measures in cubic feet (cf). Table 1-6 Residential Water Rates First 1,000 cf $1 77 per 100 cf or 748 gallons Next 2,000 cf $2.21 per 100 cf or 748 gallons More than 3,000 cf $2.90 per 100 cf or 748 gallons Irrigation $2.24 per 100 cf or 748 gallons Table 1 7 Commercial Water Rates First 250,000 cf $1.93 More than 250,000 cf $1.46 Irrigation $2.24 City of Fort Worth Water Conservation Plan 2005 1-9 Table 1-8 Industrial Water Rates First 250,000 cf $1 78 More than 250,000 cf $1.46 Irrigation $2.24 Table 1-9• Monthly Meter Charges Meter Size Service Charge 5/8" or 3/4 $5.50 1 $8.00 1 1l2" $14.50 2" $22.00 3" $47.00 4 $82.00 6" $180.00 8" $310.00 10" $485.00 1 6.2 Cost-Based Rate Structure Currently the City bases its rates on cost of service for each customer class. To realize the true cost of service, the peaking factors for each customer class need to be analyzed. The current structure does use basic peaking factors, but this does not yet fully account for the peaking characteristics. The higher the peak, the more that class will be required to pay because they are the ones driving the need for the new infrastructure which is sized to meet peak day demands. Figure 1.3 shows an initial review of the peak demands associated with each of the different rate classes. This data shows that the irrigation class has the highest peaking factor, followed closely by the residential class. Because of this, these customer classes will be the first to be reviewed regarding their peaking-factor-based cost-of-service changes. These rate structure improvements will be studied, and equitable rates will be implemented before 2010 City of Fort Worth Water Conservation Plan 2005 1 10 peaking Factors -VJhdesale -Residential -ICI use -Irtigation ........ ........._....................._.__---_.._.___._._..... ................................._.._ 600000000 3.000.000:000 _......_. . ._.._.__......._ ......................_.__._...,.__.___.....__............................................

TRWD coordinates its Operations Plan with all of its water customers and provides recommendations for the operations of regional treatment systems. 30~TAC 1 8 Implementation and Enforcement BMP3 zss.z(a)p>(1) The City has an existing ordinance which prohibits wasting water It is considering more detailed restrictions, including hours-of-irrigation prohibition during different drought stages. By the year 2015 the City will have In place all other actions described in this Water Conservation Plan. The annual audit will act as a guide for internal performance, and goals will be set each year following the audit. Implementation of the City's Water Conservation Plan is by resolution adopted by the Fort Worth City Council 30TAC 1 9 Regional Water Planning Groups zss.z(e)p )pc> The City has been working with the local Regional Water Planning Group (Region C) to help develop this group's example water conservation plan documents. This Water Conservation Plan has been discussed with Regional Water Planning Group consultants and is consistent with their methodology and structure. A City of Forf Worth Wafer Conservation Plan 2005 1 11 letter documenting that a copy of the Water Conservation Plan sent to the Chair of the Region C Water Planning Group is attached in Appendix A. 288 (z)(A-D) Section 2 Additional Conservation Efforts 30TAC 2.0 Leak Detection and Repair zss.z(a)(z)(A) The current leakage detection program uses state-of-the-art technologies and techniques to search for leaks. In addition to customer and field operations visual leakage reports, the City utilizes acoustic leak noise detectors to target suspected leaks and correlators to define leak locations. Another major part of the City's ongoing leak-detection program is the integration of Geographical Information System (GIS) tools to analyze the system down to the individual meter This data is used as a proactive tool to determine and assess the under-registration of meters and to assess areas of high and low usage. In addition, within the next five years, the City will pilot District Metered Areas (DMAs) which will act as current Best Management Practice leakage control zones. DMAs are discrete metered areas within the distribution system, usually supplying 1,000 to 3,000 properties. The leakage detection and repair studies will be used to evaluate the correct level of expenditure for ,~ leakage detection and repair programs as well as an economic level of leakage. Performance measures will be developed against the baseline values so that there is accountability and transparency within the system. These performance indicators include real losses (leakage) and Infrastructure Leakage Index (ILI). The City uses these performance indicators in preference to gpcd because they are not affected as significantly by climatic variations. The ILI is the ratio of the actual leakage within a utility system and the theoretical lowest possible level of leakage. Therefore an ILI of 1.0 would mean that the system is being run perfectly and the losses from the pipes equal the theoretical lowest level of leakage. 2.0 1 Real Losses (Leakage) Leakage from the system is generally regarded as a real loss. This is currently grouped in with all other non-revenue water in most system audits. To more accurately define real losses, specific performance measures must be developed. These should be related to real data such as miles of main or number of services so that they can be analyzed year to year Initial recommendations for real loss performance indicators are: Gallons per connection per day• Gallons per connection per day per pounds per square inch (psi); Infrastructure Leakage Index (ILI). • City of Fort Worth Water Conservation Plan 2005 1 12 PerPormancelndicators 850 ..._..__........._......~ .......................~...._ .............................._..._............................._....__._._..._..._._....~._..~_..___...................................._......_._......_....__.....~_.__.__...................... 2000 800 1998 a $ 1999 _ 750 1998 X1993 2001 o • ~ m 7997 c ° 700 E H 1994 2002 C V Taryet T'en ~ • 650 600 4000 5000 8000 7000 8000 9000 10000 Real Losses (gallons/mile/day) Figure 1 4 Fort Worth Consumption Pertormance Indicators (1992 to 2002) 2.0.2 Infrastructure Leakage Index (ILI) The Infrastructure Leakage Index (ILI) is a more complex calculation of the theoretical lowest leakage possible divided by existing calculated leakage. This is developed as a unique value for every city and includes the distance from the curb stop to the meter boxes, the pressure in the system, and the number of service lines or connections per mile of main. Within Fort Worth, the theoretical lowest leakage is approximately 3 million gallons per day This is the theoretical lowest leakage currently possible with the existing infrastructure and service connection density Fort Worth has an ILI of approximately 5.5 which means that theoretically the leakage could be reduced 5.5 times before reaching the lowest possible value. This puts Fort Worth in the average zone of II.,Is as shown in Figure 1.5 ciry or Fort wortn Water Conservation Plan 2005 1 13 s s 30 TAC 288.2(a)(2)(B) Infrastructure Leakage Index Comparison 14 - 12 x 10 ~ Fort Worth a 8 ' J ~ N ~ g I 4 c 2 0 r~ ~n r~ rn r- ~ ~ ti ~ ~ ~ n w cn ~n T T T T r N N N N N PI C7 C7 Utllitles All leak management improvements will result in reduction of non-revenue (unaccounted-for) water loss reported in the annual water audit.

Future updates of the Conservation Plan will detail how wastewater reuse projects will be implemented. 30TAC 2 5 Pressure Control and Pressure Reduction 288.2(a)(3)(E) The City will study pressure control in pilot zones within the city limits over the next five years. This will be conducted in combination with the water loss control measures developed within the district metered areas. Implementation will be discussed in the next update of the plan. 30TAC 2.6 Landscape Water Management ~ ~`~ ~ 38.2(a)(3)(F) { BMP 8,9,IQ, 1,12,20 J The existing City landscape ordinance will be evaluated to review its water use efficiency potential. This will include incentives for using native and adapted flora which require less water The City is also considering ordinances to promote rain, break, and freeze sensors on new irrigation systems. This may include a rebate program for existing systems. By 2008, the City will conduct a pilot program to assess different water-saving methodologies and technologies at City athletic fields and golf courses. The best, most effective methods will be considered for all appropriate City facilities. Once it has been determined that these techniques are effective, they will be presented to private golf courses and to customers with significant irrigated areas. 30TAC 2 7 Yearly Audit ~BMP1~~ 288.2(a)(3)(G) The City will continue to conduct a yearly water system audit using the IWA standard water audit methodology to monitor the effectiveness and efficiency of the Water Conservation Plan. 2.8 Conservation Programs for Industrial, Commercial, and B P21 ~ Institutional Accounts Water system audits and cooling audits will be the first conservation measures developed for and applied to these customers.

When existing contracts are renewed, requirements for implementation of water conservation plans will be discussed and incorporated into the respective wholesale customer contracts. The City encourages each wholesale customer to develop and implement conservation plans which reduce water use at least in line with or within 10% of those developed by Fort Worth. The basis for the development of these goals is that the City does not expect wholesale customers to implement conservation water saving plans. to exceed those developed by itself. The City does, however expect each wholesale customer to voluntarily reduce its water use through conservation practices. The targets in Table 1 11 below are recommended for each wholesale customer. Table 1 11 Wholesale Customer Targets Total GPCD Residential Unaccounted-for Water* GPCD By 2010 190 93 115 By 2015 180 88 110* ~~ Unaccounted for water targets are based on the new AWWiI water audit practices which approve the performance indicator for water losses as gallons lost per connection per day. This includes real and apparent losses. The commonly used percentage is not recommended as it is too variable depending on usage. These are guidelines and are related to the average wholesale customer in a year of average rainfall. These are voluntary guidelines 30 TAC 3 2 Measurement, Monitoring, and Metering The City will keep a database of this information for each wholesale customer and will continue with its program of metering and recording all wholesale customers' usage at point of sale. The City already has an ongoing program of proactive leak detection and meter testing and replacement to improve the level of service and cost of service to both retail and wholesale customers. 30 TAC 3 3 New Wholesale Contracts 288.5(1)(G) The City requests that each wholesale customer provide copies of their water conservation plan and required water system audit (as required by the Texas Water Development Board water audit reporting requirement as specified by House Bi113338). This will be required in any new contracts developed with wholesale customers as specified in 30 TAC Chapter 288. 30 TAC 3.4 Reservoir Operations Plan 288sp ~) Tarrant Regional Water District manages and operates all of the reservoirs supplying water to the City with the exception of Lake Worth, which the City owns and operates.
