We are ready to help you evaluate water, wastewater, and reclaimed water service to your proposed development.
Service Extension Request
A Service Extension Request (SER) is a request by a landowner or developer to extend water, wastewater, or reclaimed water service to a property. SERs are used by landowners or developers as a basis to identify required infrastructure improvements and to prepare a preliminary estimate of the cost of infrastructure for proposed development. Costs associated with the design and construction of the infrastructure identified in the SER are the responsibility of the landowner or developer.
The SER Program exists to ensure that water, wastewater, and reclaimed water systems have adequate capacity to handle new developments (individual, subdivision, multi-family, or commercial) and that proposed extensions meet City and Austin Water infrastructure planning goals.
All applicants for an SER are encouraged to use minority and women-owned business enterprises (M/WBE) in the design and construction of utility infrastructure and related facilities. Further information about the City’s M/WBE ordinance, see: Austin City Code, Chapters 2-9A, 2-9B, 2-9C, and 2-9D or visit the SMBR website.
When is an SER Required?
SERs are addressed in the City’s Land Development Code, Chapter 25-9, Article 1, Division 2. An SER is required for a proposed project:
- If Austin Water’s existing water, wastewater, or reclaimed water system is more than 100 feet from the property’s boundary
- If Austin Water’s existing water, wastewater, or reclaimed water system is not suitable or sufficient to provide the level of service required for the proposed project, or
- If the Applicant is requesting connection to a water or reclaimed water transmission main or wastewater interceptor.
When to Submit an SER
An SER should be submitted early in the development review and permitting process. Ideally, an SER would be submitted during the feasibility or preliminary engineering phase, prior to filing a formal development application (preliminary plan, plat, subdivision construction plan, or site plan).
How to Submit an SER
Please submit SER applications and associated backup materials electronically to SER@austintexas.gov. Once your application is declared complete, an invoice will be generated, and payment can then be made to the Austin Water Cashier via telephone at 512-972-0009.
When Does an SER Expire?
An approved SER expires 180 days after its approval unless a preliminary plan, plat, subdivision construction plan, or site plan is submitted, in which case the SER expires on the date that formal development application expires. Zoning applications, project assessments, development assessments, etc. are not considered formal development applications and will not prevent an SER from expiring.
Service Extension Request Forms, Fee Information and Resources
To initiate Austin Water’s technical review of an SER, please submit the following SER application form and associated backup outlined in the SER submittal checklist:
- SER Application Form: PDF | Word
- SER Submittal Checklist: PDF
- Annexation Form*: PDF | Word
- LUE Guidance Document: PDF
- SER Info Sheet – You have submitted an SER, what now?: PDF
*Land Development Code (LDC) Section 25-4-195 requires landowners to provide written request for annexation as a condition of extending municipal water and wastewater service to a property within the City’s extraterritorial jurisdiction if the property is not covered by Austin Water’s certificate of convenience and necessity (CCN). LDC Section 25-9-33(C) requires the annexation form be submitted with an SER application. The annexation form required with the SER application does not suffice as the property owner’s consent to annexation that is required under state law for an area to be annexed. For more information on CCN, please visit the Public Utilities Commission website.
A fee is charged for the review of an SER and is collected when an SER application is submitted. Additional fees may be required depending on specific aspects of an SER application or when City development permits have expired and are being reactivated or renewed. For a list of Austin Water’s fees, please see our fee schedule.
- Technical Resources for Engineers
Customers may email SER@austintexas.gov to request copies of approved SERs.
Copies of approved SERs can also be downloaded from Austin Water’s Records Access Application (RAA), an online GIS viewer available to the engineering community. The project engineer may request access to the RAA. The location, status, and Austin Water staff contact for SER applications can be obtained from the RAA.
- Service Availability Letter
Service Availability Letters are provided to verify that the tract of land is in the Austin Water service area.
