Info

Unfortunately, the simplicity of O&M has reportedly caused some plants to be outof compliance. The results of these facilities being managed incorrectly can causedetriment and degradation to the surrounding environment. For this reason, it willbe recommended for these facilities to be operated by trained personnel.Typical applications are in land development subdivisions, small cities, mobilehome parks, and recreational areas. These package treatment facilities may bebeneficial to apply as growth develops in urban areas and then to replace as thelife of the system expires. These systems would act as decentralized systems andare recommended to be operated by public utilities to provide a service for thepublic health.13.6 Proposed Wastewater Collection FacilitiesThe proposed regional and decentralized facilities are recommended to reuse100% of the effluent. With stringent treatment levels for all collection facilities,the treated wastewater can be reused within the community it is serving. There isopportunity for reuse in both centralized and decentralized systems. The reusewater can serve to irrigate developments in nearby communities. Hospitals,schools, theaters, manufacturers, industries, and other facilities that require largeamounts of water for irrigation and cooling of buildings are target customers ofreclaimed water.Although the recommendation is to reuse 100% of the wastewater, it may notentirely feasible for utilities to provide this service in existing facilities. The costmay exceed the benefits. Also, development and design of new facilities shouldemploy this strategy with further investigation into the effects of instream flowsand current laws.The proposed regional collection facilities are to provide sewer services to theLockhart, Martindale, Luling, and Peach Creek service areas as discussed earlier.Klotz Associates Project No. 0972.000.000January 201013-10Caldwell County Regional Water and Wastewater Planning StudyFinal Report
The projected flows developed in Section 9 and found in Table 9-3 were furtherevaluated to determine wastewater flows for the service areas mentioned. Apercentage of the expected population was assigned to each service area toestimate a wastewater flow for that service area. The percentages and expectedwastewater flows are shown in Table 13-2. Lockhart was expected to produce40%, Luling 35%, Martindale 20% and Peach Creek 5% of the projectedwastewater flows.Table 13-2Service Areas Projected Wastewater FlowsTotal Projected Wastewater Flows 2010 2020 2030 2040(MGD) in given Year 4.723 6.636 8.864 10.200Service Area Percentage Wastewater Flows for Service AreasLockhart 40% 1.889 2.654 3.546 4.080Luling 35% 1.653 2.323 3.102 3.570Martindale 20% 0.945 1.327 1.773 2.040Peach Creek 5% 0.236 0.332 0.443 0.51013.6.1 Option 1 - Regional FacilitiesThe regional facilities option is to develop one regional facility in the fourdetermined service areas. This option reduces the number of treatment systemswith an anticipated lower unit cost of treatment. However, with a 100% reusedistribution system, this may prove to be more costly than other options. Reuselines in a regional facility may be limited.13.6.2 Option 2 - Decentralized/ Package Treatment SystemsIt is suggested by other industry professionals to consider implementing systemsdelineated by smaller drainage basins to serve local subdivisions andcommercial/industrial sites. Having a smaller community collection and reusedistribution system can provide environmental benefits that outweigh otherKlotz Associates Project No. 0972.000.000January 201013-11Caldwell County Regional Water and Wastewater Planning StudyFinal Report
