The objective of this project is to provide a gravity interceptor that will eliminate the existing Bee Cave and Treemont Lift Stations. Conceptually, the project consists of approximately 7,500 ft of 21-inch sewer running along Thousand Oaks Drive, Regents Park, Chatelaine Drive and Barton Skyway. The sizing of the proposed 21-inch interceptor will be evaluated and verified based on design and stakeholder feedback about potential growth capacity. The proposed project includes a tunnel crossing under Mopac at the Barton Skyway overpass. The proposed interceptor would begin upstream of the Bee Caves Lift Station near MH 16860 and convey wastewater into the Barton Creek Interceptor at MH 17045, which is near the bottom of the Spyglass access to the Barton Creek Greenbelt. The proposed interceptor shall include provisions to connect to a conceptual gravity interceptor that would run parallel with the Mopac Expressway
