Site work for a water / sewer project in Austin, Texas. Completed plans call for site work for a water / sewer project.

As of 12/10/2025, this project has not yet been awarded. It won't be awarded until after March 2026. Description: Thousand Oaks Interceptor Summary: Wastewater infrastructure in poor condition and at capacity in the environmentally sensitive Barton Creek area present a risk of SSOs. Construction of 7,500 feet of new gravity sewer would relieve pipes and two lift stations to reduce the risk. WBE - 3.09% 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 Proposed Contract Execution Date: 04/2026 ; Construction Phase approximately 24-30 months Major Scopes of Work Civil Engineering (92517) Tunnels and Subways/Engineering (92594) Surveying Services (90779) Environmental Permitting Services (92670) Other Scopes of Work Geotechnical - Soils (92546) Environmental Engineering (92535) Real Estate/Land Consulting (91899) Utility Locator Service (Underground) (96291) Traffic and Transportation Engineering (92593) Structural Engineering (92588) Cost Estimating (96121) Drainage Engineering (92528)
