4. Forecasting Future Water Resource NeedsSUMMARY: This section forecasts future demands for water and wastewatertreatment in the region.Section 4. Forecasting Future Water Resource NeedsWater and wastewater demand forecasts, along with the resource assessments(Section 3), form the foundation for water planning in the Middle ChattahoocheeRegion and serve as the basis for the selection of water management practices(Section 6). The tables and graphics in this section present the regional water andwastewater forecasts for 10-year intervals from 2010 through 2050 for four water usesectors: municipal, industrial, agriculture, and thermoelectric generation.During development of this plan, EPD requested water use forecasts for the four usesectors from the Alabama Department of Environmental Management (ADEM).Because of the current tri-state litigation, ADEM did not provide forecasts, onlycurrent day demands were provided. The Middle Chattahoochee Council directlyappealed to ADEM requesting this data as well and had not received a response asof the writing of this plan.4.1 Municipal ForecastsThe residential and commercial water demand and demands of small (non-majorwater using) industries were projected as one combined category and referred to asthe municipal demand. Demands for major water using industries were projectedseparately and are discussed in Section 4.2.Population ProjectionsMunicipal water and wastewater forecasts are closely tied to the populationprojections for the counties within the Middle Chattahoochee Region. The populationprojections were developed by the Governor’s Office of Planning and Budget (OPB)for the entire state. The OPB is charged in state law (O.C.G.A. 45-12-171) with theresponsibility for preparing, maintaining, and furnishing official demographic data forthe state. The population projection results by county are shown in Table 4-1.Table 4-1: Population Projections by CountyCounty 2010 1 2020 1 2030 1 2040 2 2050 2 2Difference(2010 - 2050)% Change(2010 –2050)Carroll 120,019 155,641 198,891 243,310 289,439 169,420 141.2%Chattahoochee 15,641 21,182 23,617 25,624 27,991 12,350 79.0%Clay 3,223 3,150 3,006 2,866 2,745 -478 -14.8%Haralson 30,062 36,779 44,436 51,107 57,383 27,321 90.9%Harris 31,178 41,001 52,606 65,047 78,213 47,035 150.9%Heard 11,898 14,407 17,033 20,145 23,789 11,891 99.9%2MIDDLE CHATTAHOOCHEE05.02.2011Georgia State-wide Water Management Plan 4-1
