Rocky Brushy Creek Watershed Mgmt. Plan (2007) -- Part 2

CHAPTER 9Total per capita water use for the period, 1993 – 2002, ranged from a low of 105 gallons per capitaper day (gpcd) in 1998 to a high of 154 gpcd in 1995 for both surface and groundwater sources(Figure 9-4). Per capita water use showed a slight decreasing trend over that period, but it was notstatistically significant. In 2003, Hillsborough County utilized approximately 70% of its reusecapacity. On a per capita basis, the actual rate of reuse amounted to 30.54 gpcd, while the reusecapacity equaled 43.4 gpcd.TBW/ Northwest Hillsborough Per Capita Water Consumption, 1993-2002180160140120Gallons Per Day1008060402001993 1994 1995 1996 1997 1998 1999 2000 2001 2002YearTBW/ Northwest HillsboroughFigure 9-4 Per Capita Water Use in the NTBWUCA(Source: SWFWMD, Estimated Water Use, 2002)Figure 9-5 shows the cumulative rainfall (inches) and the “variance from normal” (NOAA) for theperiod between May 2005 through April 2006 for Tampa International Airport (TIA), while Table 9-2lists other rainfall stations that are located within the NTBWUCA and operated by SWFWMD. TheTIA station reports an above-normal rainfall condition equaling 2.7 inches at that location.However, due to the nature of rainfall over a large geographic area, the rainfall surplus for the areaas a whole as represented by the nine rainfall stations listed in Table 9-2, the rainfall amounts to0.7 inches over the April 2005 – March 2006 time period. In addition, the average rainfall amountfor March 2006 in the Northwest Hillsborough area was 0.13 inches, which represents a departurefrom the normal March rainfall amount totaling -3.24 inches. Since January 2006, the departurefrom normal for the time period January – March was 1.49 inches.9-9 Rocky/Brushy Creek Watershed Management Plan
