associated costs. Efficient and functional planning of these facilities with plannedcommunity development is necessary to be cost-effective.This alternative also considers phasing out ineffective systems that are notfunctional. The collections systems can be removed and lines extended to connectto a network in place. Connection to a sewer main will route the wastewater to aregional facility. These systems should be strategically placed in locations thatallow for the option to be phased out.13.6.3 Option 3 - Combined FacilitiesDecentralized systems, in combination with regional facilities, can work togetherto provide load reductions in streams and rivers. Decentralized systems cancollect, treat the wastewater and enable local reuse of the water. This approachpromotes reuse of treated wastewater. The unusable sludge slurry can be piped toa regional treatment plant and treated at that plant prior to disposal.13.7 Proposed Regional Wastewater FacilitiesThe recommended regional wastewater facilities for Caldwell County arepresented in Exhibit 13-4 and include:• Lockhart Regional Wastewater Treatment Plant in 2040 is expected to treat4.1 million gallons per day receiving 40% of the total wastewater produced inthe county. Approximately 32 miles of main wastewater collection lines areproposed for this treatment plant.• Luling Regional Wastewater Treatment Plant in 2040 is expected to treat 3.6million gallons per day receiving 35% of the total wastewater produced in thecounty. Approximately 33 miles of main wastewater collection lines areproposed to service this treatment plant.Klotz Associates Project No. 0972.000.000January 201013-12Caldwell County Regional Water and Wastewater Planning StudyFinal Report
• Martindale Regional Wastewater Treatment Plant in 2040 is expected to treat2.1 million gallons per day receiving 20% of the total wastewater produced inthe county. Approximately 11 miles of main wastewater collection lines areproposed to service this treatment plant.• Peach Creek Regional Wastewater Treatment Plant in 2040 is expected totreat 0.6 million gallons per day receiving 5% of the total wastewaterproduced. Approximately 9 miles of main wastewater collection lines areproposed to service this treatment plant.Table 13-3 presents estimated cost for each regional treatment plant based on aplant cost of $3.75 per gallon of treatment capacity and in-place wastewater maincost of $125 per linear foot of pipeline.
