For Properties outside the City limits of Austin:

I further understand that permanent water and/or wastewater service and the setting of a permanent water meter requires the successful passing of a Final Plumbing Inspection. Any water meters set or water and/or wastewater service provided prior to passing this inspection are considered temporary services, and these services may be discontinued without notice and may not be resumed until inspection requirements are met.

Tap Expiration:

The Tap Permit will expire 2 years after the date of issue; refunds will not be processed after the expiration date. To keep the tap permit active after the 2-year period, for both properties inside and outside Austin city limits, you must have an active building or plumbing permit. For more information, contact the Austin Water Utility at 512-972-0000.

Construction Projects 500'(feet) or less:

For projects totaling 500' or less of water lines and/or 500' or less of wastewater lines, the following documents and payment must be received by the Austin Water Utility's TAP Office before a City Inspector will be assigned. The contractor cannot begin utility construction work in the Right of Way (ROW), which begins at the property line, or the Public Utility Easement (PUE) until an inspector has been assigned to the project. The contractor MUST give 48 hours notice to the assigned inspector prior to beginning construction of utilities in the ROW or PUE.

  1. Five (5) copies of approved utility construction plans, each set is to include:
      1. Cover sheet
      2. Construction notes
      3. Utility plans
      4. Detail sheets
      5. Copy of final plat date
  2. Note: For some small projects, this information may be included on one sheet. Note that a plan is not considered "approved" until it has been reviewed and signed, within the last 12 months, by an Austin Water Utility Engineer.
  3. Two (2) copies of an executed contract or proposal; the contract or proposal must be signed and dated by both parties.
  4. Payment of the Construction Inspection fee (which is determined by the total cost and quantities of material installed in the ROW). This fee is a percent of the total estimated construction costs in the ROW only.

Construction Projects Greater Than 500'(feet):

For projects totaling more than 500' of water lines and/or more than 500' of wastewater lines, contact the City of Austin's Public Works Department, Construction Inspection Division at 512-974-7150 or 512-974-1567.
