The city is in the geographical center of the county and is approximately 16 miles south ofthe Red River. Paris is 90 miles southwest of Texarkana, and 105 miles northeast of Dallas. The population of Paris is 25,898 based on the 2000 Census data. The historical population data for Paris and lamar County are presented in Figure 2. lamar County experienced rapid growth through 1920, and then experienced declining population until 1960, atwhich time a steady population increase began again. The population of Paris has been steadily growing. The trend analysis indicates that Paris has added approximately 187 people per year since 1850. This normally translates to approximately 60 new houses per year. Much of the growth can be attributed to the steady influx of manufacturing into the City of Paris. The City has several large employers including Campbell Soup, Kimberly-Clark, Sara lee, and Turner International Piping. Additionally, the health care industry is a large employer in the City. The City experienced a major fire in 1916, and all of the downtown area was reportedly lost. The (8 D was reconstructed, and most of the water lines in the central portion ofthe city were constructed during the 1920's. Project Background The City is currently experiencing an unacceptably high amount of unbilled water in the drinking water system, and Carter~:Burgess the major objective of this project is to identify the sources of the unbilled water. In order to incorporate the results of this project into the on-going rate study, the time frame for completing this project is two to three months. The City's distribution system is shown as a simplified schematic diagram in Figure 3. The system currently has 9,900 billed accounts, and provides water to 174 meters that are two-inches or larger. Additionally, the lamar County Water Supply Corporation is a relatively large customer of the City of Paris. The residential/commercial customers average daily consumption was 2.6 million gallons during the previous year. For a city with a population of 25,898, this is equal to a per capita consumption of 100 gpcd, which is very reasonable. Unbilled, or unaccounted for, water can be the result of a number of different factors including: * Customers that are not metered: . Parks . Water main flushing . Fire protection . Construction . Street washing . City irrigation * leakage in the system * Inaccurate meters * Inaccurate billing software * Meters that have been pulled and replaced with jumpers 15
