Emergency Storm Drain Repair During Denver Storm Events
An independent, licensed plumbing contractor. Not affiliated with Denver Water or the City and County of Denver.
An emergency storm drain call is active flooding, a collapse that has opened a void at the surface, or a blockage putting water into a building right now. Denver Sewer and Water responds to those, relieves the water first where it can be relieved safely, and diagnoses the cause once the property is out of danger.
- Active flooding and water entering buildings.

What Counts as a Storm Drainage Emergency?
Water entering a building through a window well, a below-grade doorway, or a basement egress is the clearest case. So is water accumulating against a foundation with nowhere to go, because that becomes water inside the building shortly afterwards.
The other emergency is structural. When a storm run collapses, the soil above it migrates into the void and eventually the surface drops. A sinkhole over a storm line on a driveway or a walkway is both a failure and a hazard, and it will keep growing as long as water keeps running into it.

- Water entering a below-grade space during a storm.
- A window well filling and rising toward the sill.
- A depression or hole opening over a known drain run.
- A basin backing up and flooding a driveway or lot.
- Water ponding against a foundation with no outlet.

How We Diagnose It
What We Do First on a Storm Emergency
Relief where relief is possible. That often means opening and clearing the collection point that has blocked, because a basin packed with leaf mass during a storm is a blockage that can be removed in minutes and it is regularly the whole problem. Where the line itself is blocked, vacuum extraction at the nearest access can restore enough capacity to stop the damage.
Where the failure is a collapse, the priority changes to making it safe. The void gets secured and, where possible, water gets diverted away from it, because water continuing to run into a collapse enlarges it.
Emergency response sequence
- Identify where the water is entering and stop that path if possible.
- Clear the collection point that has blocked.
- Vacuum or jet the run to restore capacity.
- Secure any surface void and divert water away from it.
- Camera the system once the event has passed.
How an Emergency Storm Call Runs
- 1
Call and triage
What is flooding, where the water is entering, and whether there is a void at the surface. That sets the response and tells you what to do before we arrive.
- 2
Relieve the water
Clear the blocked basin or run and restore enough capacity to stop the damage progressing.
- 3
Secure any hazard
Voids and collapses fenced off and water diverted away from them.
- 4
Diagnose and scope
Once the event has passed, camera the system and price the permanent correction with the cause identified.

What Denver Customers Say About Working With Us
“Denver Sewer and Water was a great experience. We had been out of water due to a water main leak into the house for 2 weeks. They came out, gave a go”

“Very direct and to the point. Extremely efficient and professional.”
What Emergency Storm Work Costs
Emergency response pricing reflects the hour and the conditions, and we tell you that on the phone rather than after. What we will not do is quote a permanent repair while the water is still running, because nobody knows the cause yet at that point.
The permanent scope gets priced after the camera survey, when it can be priced honestly.
