Sewer/water service repair jobs must have a permit from either the Infrastructure Department or the Building Department, not both. If you are unsure if your work will extend into the ROW call 720-977-6210 for assistance.

The Infrastructure Department issues permits to licensed contractors for:

• Repairs to Thornton utilities that extend from the yard to the ROW and are within City limits.
• Repairs to the connection point/tap to Thornton utilities that are outside City limits.
• Chase drains within City limits, excluding Heritage Todd Creek

Typical processing time for this type of permit is one to two business days.

Visit the Infrastructure Right of Way Permits page to learn more.
