Proposa/ Comprehensive Water Distribution System Audit Section 5 Project Understanding & Approach Project Understanding Background The Ciry of Paris, Texas is located in nartheastTezas in lamar County, os indicated in Figure 1. The ciry is in the geographimlcenterofthemunryandisapproximotely 16 miles south of the Red River. Paris is 90 miles southwest of Tezarkono, and 105 miles northeast of Dalias. The papulation of Paris is 25,898 based on the 2000 Census data. The historical papulation data for Paris and Lamar Counry are presented in Figure 2. Lamar (ounty experienced ropid growth through 1920, and then ezperienced declining papulation until 1960, at which time a steady population increase began again. the major objedive of this projed is to identi{ythe sources of the unbilled water. In order to incorporate the results of this project inta the on-going rate study, the time frame for completing this projed is two to three months. The Ciry's distribution system is shown as a simplified schematic diagram in Figure 3: The system mrrentiy has 9,900 billed accounts, and provides water to 174 meters thatarelwo-inchesorlarger. Additionally,theLamarCounry Water Supply Corporation is a relatively lorge customer of the Ciry of Paris. The residentiaVcommercial custamers average daily consumption was 2.6 million gallons during thepreviausyear. Foracitywithapopulationof25,898, this is equal to a per mpita mnsumption of 100 gpcd, which is very reasonable. Unbilled, or unaccounted for, water can be the result of a number of different fadars induding: The population of Paris has been steadily growing. The trend analysis indicatesthat Paris has added approximately 187 people per year since 1850. This normally translates to approzimately 60 new houses per year. Much of the growth can be attributed to the steady inHuz of manufaduring intotheCityofParis.

The Ciry experienced o major fire in 1916, and all of the downtown area was reportedly lost. The CBD wos reconstruded, and most of the water lines in the central portion ofthe cirywere construded during the 1920's.
