caldwell county regional water and wastewater planning study

Municipal water demand projections in the 2006 Region L Plan for CaldwellCounty were based on 122.5 gallons per capita per day (gpcpd) for year 2010 and113.2 gpcpd for the year 2040. These demands are lower than the demandsestimated for the whole of the South Central Region in the 2006 Region L Plan of143 gpcpd in the year 2010 and 135 gpcpd in the year 2040.The Caldwell County Study reported on herein used 150 gpcpd for the planninghorizon of 2010 to 2040. These values were adopted based on surveys completedfor water supply entities in Caldwell County. Water conservation practices couldreduce the per capita demand by 10 to 20 percent. The larger per capita use ratesin the Caldwell County study increase the volume of future water that must bedeveloped to meet future needs when compared to the 2006 Region L Plan.Water demands for mining are also expected to gradually increase about 1 ac-ft adecade from 14 ac-ft in 2010 to 17 ac-ft in 2040. Manufacturing increases about 316,000GRAPH 8-2Caldwell County Water Demands by Use Category14,00012,000MiningManugacturingLivestockIrrigationMunicipal10,000Acre - Feet8,0006,0004,0002,00002000 2010 2020 2030 2040 2050 2060YearKlotz Associates Project No. 0972.000.000January 20108-4Caldwell County Regional Water and Wastewater Planning StudyFinal Report
