SEWER USE & DRAINAGE PERMITS (SUDP)
Before any building or construction may begin, a sewer use and drainage permit (SUDP) must be obtained for each building and/or individual tenant associated with a project.
As of August 2018, the SUDP application has been combined with electronic building permit applications for a more streamlined submittal process and faster review times for many SUDP customers. SUDP reviews will now start when a building permit application is received.
How to apply
Submit SUDP and building plans at the same time to PlanReview@denvergov.org.
- Save all files as PDFs and name them: DocumentName_Address_Date.pdf (e.g., UtilityPlan_201WColfax_11-1-2017.pdf)
- All plans, reports, surveys, and other documents prepared by an architect, engineer, or surveyor must bear their seal on each sheet and a valid electronic signature on the cover page.
- For large files that cannot be sent as attachments, email a link to Dropbox, Google Drive, etc. where staff can download the files. The documents must be available to download without a password.
Important Note:
If the work does not require building permits, or if you will obtain a same-day building permit in person, use one of the following methods to apply for an SUDP review:
- Submit SUDP materials in person to the SUDP counter
- Submit by email to WastewaterPermits@denvergov.org

Additional resources
SUDP invoices must be paid prior to December 31 of the invoice year. Additional fees at the new year's rate may be assessed and payment required for any prior-year invoices.
For information on standard fees, see Public Works / SUDP on the Building and Land Development Fees webpage.
Before installing or replacing a grease interceptor, consult these resources:
- GI sizing worksheet (Requires Microsoft Excel Version 2003 or later)
Grease interceptors will need a plumbing and an SUDP review.
In a restaurant or commercial kitchen, a change to the type of cuisine served, an increase in seating capacity, or a change in the cooking appliances could all have an impact on grease interceptor sizing.
For projects that require a grease interceptor, make sure to connect all fixtures in the kitchen and food prep areas to the grease waste sewer line, which is then directed to the appropriately sized grease interceptor, prior to connecting to the domestic sanitary sewer system for the building. Bar areas, beverage stations, restrooms, and any other area that is not in the kitchen or intended for food prep should NOT be directed to the grease waste sewer line, but rather connected directly to the domestic sewer system for the building.
