Denver Wastewater Tap Fees Explained
An independent, licensed plumbing contractor. Not affiliated with Denver Water or the City and County of Denver.

The Categories of Charge on a Wastewater Tap Project
Owners are usually surprised not by any single charge but by how many separate bodies are involved. A wastewater connection can involve the wastewater authority, the local building department, and the right of way authority, each with its own fee schedule.
The clean way to think about it is two sides. Authority side charges pay for capacity in the public system and for review and inspection of your connection. Contractor side charges pay for the physical work of getting your service to the main.
Every category below is charged by a public body, not by us. We help you identify which ones apply so nothing shows up unexpectedly mid-project.
(720) 935-6221Charge Categories You May Encounter
- Connection or tap fee for joining the public sanitary system.
- System development or plant investment charge tied to capacity.
- Permit fee for the tap or the plumbing work.
- Inspection fee for the required inspections.
- Right of way or street cut permit fee where work is in a public street.
- Restoration or pavement fee where the authority controls surface repair.
- Ongoing wastewater service charges billed after connection.

How We Diagnose It
Who Authorizes the Tap and Who Performs the Tap
Denver Sewer and Water is a private, family owned and operated contractor. We are not Denver Water or the City and County of Denver. We do not issue permits, set fees, own the mains, or approve service. The utility or municipality with jurisdiction does all of that.
The wastewater authority sets connection and capacity related charges. The municipality sets permit, inspection, and right of way charges. Ongoing service billing comes from the utility after the connection is live.
Denver Sewer and Water charges only for the construction work. We do not add a markup to authority fees and we do not receive any part of them.
The authority authorizes. The licensed contractor performs. Below is the split for this type of work.
Authority Side and Contractor Side
- Authority: Sets every fee schedule and publishes it.
- Authority: Collects tap, capacity, permit, and inspection charges from the property owner.
- Authority: Bills ongoing wastewater service after connection.
- Denver Sewer and Water: Identifies which fee categories apply to your project type and address.
- Denver Sewer and Water: Confirms current published figures with the authority before scheduling.
- Denver Sewer and Water: Quotes construction cost separately and transparently.
- Denver Sewer and Water: Coordinates payment timing so approvals are not held up.
How Fees Sequence Through a Project
- 1
Scope Determines the Fee Set
New connection, replacement, upsizing, and change of use do not carry the same charges. Scope comes first.
- 2
Authority Confirmation
We confirm the applicable categories and current amounts with the authority for your address, in writing.
- 3
Payment Before Authorization
Authorities generally require applicable fees to be settled before a permit is issued and work is authorized.
- 4
Inspection and Service Start
After inspection and acceptance, ongoing service billing begins on the utility's cycle.

Why We Do Not Publish Amounts
Fee schedules change, they differ by jurisdiction, and they vary by service size and use type. A number published on a contractor website is out of date the moment the authority revises its schedule.
We do not publish fee amounts. Tap fees, plant investment fees, permit fees, and inspection fees are set by the authority with jurisdiction and change on their schedule, not ours. We confirm the current figures in writing with that authority for your address before work is scheduled.
