New water and wastewater service connections (Adobe pdf) are installed by the customer* and maintained by Austin Water. Plans must be prepared by a Texas Licensed Professional Engineer and submitted to Austin Water for approval prior to installation.
* Qualifying residential customers may be able to retain existing water and wastewater service connections, please contact the Austin Water Taps Office for details.
After Austin Water’s Taps Office has determined that new water and wastewater service connections are needed, you will need to submit an engineered tap plan to the TAP Plan Review Team. Customers with approved tap plans will be allowed to pay connection fees. No building permits will be issued until all tap fees have been paid.
Once the plans have been approved, a right-of-way permit from the City of Austin’s Transportation Department must be obtained prior to the installation of service connections.
Note: Property Owners
In addition to new service connections, property owners are responsible for installing yard lines (water and wastewater pipes located between the property line and the building they serve).

- Retaining an Existing Wastewater Service Line
In alignment with the City of Austin’s and Austin Water’s Strategic initiatives on Affordability, Austin Water continues to evaluate on a case-by-case basis, the use of existing wastewater service lines, if current protocols prohibit the use of the existing residential wastewater service.
Property owner may choose to reuse an existing wastewater service so long as the service is deemed to be non-defective in accordance with the City’s Code of Ordinances, Chapter 15-11, COA 15-11-4 (E). If the applicant chooses to reuse the existing wastewater service and if the existing service is within the ½ critical root zone (CRZ) of a protected tree or within 5’ of an obstruction like an electric pole and made of materials such as vitrified clay, Austin Water Residential Tap Plan Review may require a video recording of the interior condition of the existing wastewater service lines proposed to remain in place, to ensure the existing service is compliant with City requirements, based on location, age and material of the service.
The video should be a recording, of the original video, collected by a wastewater inspection camera (not a phone video of the inspection screen). The video should be clear, include identifying location information, and be recorded at a speed that allows for the full evaluation of the service line. Should the applicant propose a brand-new service, the existing service will be required to be abandoned as prescribed in UCM Section 2.8.1.
In addition to affordability, this initiative will reduce the risk of wastewater service interruptions to the homeowner and potential damages to plumbing systems due to wastewater backups from tree roots or utility pole proximity. In addition, the risk for unauthorized wastewater discharges into the environment are also mitigated.
The above allowance will be afforded to all new tap plans received on or after October 1st, 2022, that propose to reuse an existing service under this program.
