The City's population according to the 2010 U.S. Census was 18,376. <br />gpcd = gallons per capita per day <br />Based on metered usage of all the City' customer categories the per capita water usage of the service area <br />population was an average of 162 gallons per capita per day (gpcd) from 2010 -2013. An estimate of per <br />capita usage of the residential population was an average of 101 gpcd from 2010 to 2013. This usage <br />number represents the average amount of water required every day for each person in the RESI, RESO, and <br />MF categories. These per capita values do not account for water use that is not metered as part of the billing <br />system (for example, bulk water), real water loss, or apparent water loss. To capture the total amount of <br />water per capita required at the entrance to the system, the water treatment plant production must be used <br />in the calculation. The average per capita water required from the water treatment plant was 185 gpcd from <br />2010 to 2013. <br />2 -8 WBG071714052946BSO <br />
