Council Committee, Boards and Commission Action: March 11, 2026 – To be reviewed by the Water and Wastewater Commission. Additional Backup Information: Austin Water’s collection system is a large and complex system, consisting of approximately 3,000 miles of wastewater mains and serving approximately one million customers, and is fundamental for the transfer of the wastewater to Austin Water’s treatment plants. Due to deterioration from the harsh conditions of the wastewater environment, collection system assets require ongoing repair and replacement to prevent sanitary sewer overflows (SSOs). The Thousand Oaks Interceptor project will install approximately 7,500 linear feet of new wastewater line from the Bee Cave Lift Station to the Barton Creek Interceptor upstream of the Barton Spring Pool. This new wastewater main will run along Thousand Oaks Drive, Regents Park, Chatelaine Drive and Barton Skyway and was identified and selected for replacement based upon its physical condition, number of SSOs, and hydraulic inefficiencies. These new wastewater improvements will increase system resiliency and will also allow for decomissioning of the Bee Cave and Treemont Lift Stations. Construction of the new wastewater interceptor will require lane closures or traffic detours, impacting public transportation. Any necessary wastewater service outages will be communicated to allow customers sufficient notice and time to prepare. These outages are expected to be minimal in number and duration.  Item 4 Water & Wastewater Commission: March 11, 2026 Council: March 26, 2026 A delay in contract approval could have a negative effect on infrastructure stability and an increased risk of sanitary sewer overflows. This request allows for the development of an agreement with the selected firm. If the City is unsuccessful in negotiating a satisfactory agreement with the selected firm, negotiations will cease with that firm. Staff will return to Council so another qualified firm may be selected, authorizing new contract negotiations. This project is located within District 8. Water and Wastewater Commission: March 11, 2026 City Council: March 26, 2026 EANES CREEKBARTON CREEKSKUNK HOLLOWEANES CREEKS MOPAC EXPY SBS MOPAC EXPY NBS MOPAC EXPY SVRD SBSMOPACEXPYSVRDNBBARTONSKWYTHOUSANDOAKSDRSPYGLASSDRCHATELAINEDRHOLLYHILLDRREGENTSPARKBEECAVERDMONTEBELLORDINTERVAILDRWILDERNESSDRTAMARRONBLVDBARTONHILLSDRLIBERTYPARKDREANESCIRBARTONSBLUFFLNAPRICOTGLENDRHONEY TREE LNFORESTBENDDRVIAFORTUNATREEMONTDRCAPITALPKWYEANESWOODDRHAVRELAFITTEDRBRIGHTWOODDRDANA CVCHATELAINE CVWILDERNESS CVLOVELAND CVBRIANS MEADOW CVFOXCROFT PLBEECAVERDWastewater Needs¯05001,0001,5002,000Feet6943.049 - Thousand Oaks InterceptorItem: 4WAYMAKERWAYWESTLAKEDRWESTLAKEDRPLAZAON THELAKEAirportBlvdDessauRd.71WHITEROCKDR351129071Project Limits35HARRISBRANCHPKWY2244360WAYMAKERWAYWESTLAKEDRWESTLAKEDRPLAZAON THELAKEAirportBlvdManor Rd.WHITEROCKDRHARRISBRANCHPKWYAirportBlvd.MLK Blvd.MLK Blvd.MLK Blvd.Lamar Blvd.EParmerLn.71 Item 4 Water & Wastewater Commission: March 11, 2026 Council: March 26, 2026 M/WBE Summary Participation subgoals stated in the solicitation were 1.57% African American; 3.99% Hispanic; 3.45% Native/Asian American; 3.09% WBE.
