13.3 Wastewater System PlanningThe development of wastewater facilities will be based on growth and landtopography. A gravity flow systems is the expected design. Assumptions of landdevelopment are made based on typical patterns that occur along corridors.Exhibit 13-1 illustrates the general areas that were considered in the evaluation offuture growth. Steep elevation zones, floodplains, and drainage basins were thegoverning factors for determining the locations of the regional facilities and thedecentralized systems.It will be expected that as the population grows, the areas between San Marcos,Luling, Lockhart, and Mustang Ridge will become densely populated. Area 2 asshown in the exhibit is expected to show the initial growth with developmentfollowing in areas 1 and 3. Areas 4 and 5 are not expected to grow as rapidly andbecome as densely populated. The construction of SH 130 will bring about achange in the land development for the area.13.4 Wastewater Collection System Service AreasThe location of collection systems were based on the naturally occurring drainagebasins. There are three major drainage basins in the county which can be utilizedto develop systems transported by gravity. Gravity systems require very littleenergy and are typically less costly to develop and maintain than systems thatrequire pumping. Evaluations of the service areas, as shown in Exhibit 13-2, weredefined as follows:1. The Lockhart Regional Facility Area - This service area willinclude Lockhart and the northern area of the county that willdevelop as SH 130 develops from Mustang Ridge.Klotz Associates Project No. 0972.000.000January 201013-3Caldwell County Regional Water and Wastewater Planning StudyFinal Report
