Water Facilities Master Plan Population and Water Demand Projections A 4-2 KM2740.Sec4.doc 11/26/2007 The second development (mentioned earlier) concerns a general shift in the northern boundary of the South Dade area once the proposed South Miami Heights Water Treatment Plant comes into service in 2012. The northern boundary will be shifted northward such that portions of the population currently within the Alexander-Orr subarea will be within the South Dade subarea. Figure 4-1 illustrates the boundary shift. The boundary shift will cause a general redistribution of service between the Alexander-Orr and South Dade areas, but will not have other effects on the population expected to be served by MDWASD. In 2030, MDWASD will serve potable water to approximately 87% of the total County population. Table 4-2: Population Projections to be Served by MDWASD Year Total MDWASD Total County 2007 2,250,944 2,494,805 2012 2,349,221 2,670,569 2017 2,487,519 2,834,172 2022 2,609,268 2,979,533 2027 2,731,018 3,124,894 2030 2,804,068 3,212,111 Sources: Miami-Dade Planning & Zoning Department 4.3 Historical Water Use Historic water use figures were obtained from MDWASD and reflect water provided by the Hialeah-Preston, Alexander-Orr, Everglades, Leisure City, Newton, Elevated Tank, and Naranja WTPs and associated wellfields. These water use figures provide the basis for forecasting future water demands for MDWASD’s service area. Table 4- 3, referred to as Table F in previous submittals to MDWASD and the SFWMD, provides the historical raw and finished water use by subarea for Year 2001 through Year 2006. Information shown in Table 4-3 includes per capital annual average and maximum month water use. 4.4 Water Demand Projections The water demand projections presented herein are based on initial system-wide finished water daily per capita use rate of 155 gallons per capita per day (gpcd). The per capita use was determined by taking a 5-year average from 2002 to 2006. The initial per capita rate was adjusted to reflect reductions resulting from water conservation and reuse irrigation water projects. Table 4-4, referred to as Table G in previous submittals to the SFWMD, provides the projected raw and finished water use for Year 2007 through Year 2030. Table 4-4 also provides projected raw water pumpage from the Biscayne and Floridan Aquifers in
