The project includes transmission lines to carry treated water from the new surface water treatment plant to existing utility districts for distribution. Construction consists of traditional open cut trench, as well as trenchless methods such as horizontal directional drilling, bore and jack and tunneling. There are several major obstacles along the path such as creek crossings, existing pipelines and road and a railroad crossing. The use of trenchless installation methods will allow the new transmission lines to be constructed without interrupting or damaging these existing obstacles. To the south of the SWTP 12,900 linear feet of 30-inch PVC line will be constructed to reach Sienna Plantation Water Plant #1. Additionally, 6,680 linear feet of 10-inch PVC line will be constructed along a parallel route. This pipeline will function as an irrigation line to transport reuse water from the SWTP to the existing lake system in Sienna Plantation. To the north of the SWTP, 7,585 linear feet of 36-inch PVC line will be constructed to the future Fort Bend Toll Road extension. From this location, the line will be branched off for a future extension and then will continue for another 3,615 linear feet as a 16-inch PVC line to reach Sienna Plantation Water Plant #2. A second line along this route will consist of 9,050 linear feet of 16-inch PVC line to the existing Well #5 in Sienna Plantation. The water from this well will be used as a back-up supply source for the SWTP and could also be used as an aquifer storage and recovery line in the future. These transmission lines have been adequately sized to allow for future extensions to the other utility district water plants in the area as the SWTP is expanded.
