Storm Drains Are Not the Same as Sanitary Sewers
Storm drains are designed to collect and move rainwater, snowmelt, and surface runoff away from properties, streets, and paved areas. In Denver, the stormwater system is completely separate from the sanitary sewer system.
That distinction matters because storm drain problems need to be evaluated as drainage and runoff problems, not treated like standard inside-plumbing clogs. A good storm drain page should make that difference clear right away.
Standing Water, Flooding, or Blocked Runoff? Act Before It Gets Worse.
Storm drain issues can escalate quickly during rain events, snowmelt, or repeated runoff cycles. If water is pooling near a building, parking lot, driveway, curb line, or drainage inlet, the safest next step is to have the system evaluated before the damage spreads.
Do not assume the issue is minor if the flooding goes away after the storm. Recurring standing water often points to a blocked, damaged, undersized, or poorly functioning storm drainage system.

Fast action matters when drainage failure can affect structures, pavement, or site safety.
Storm Drain Service Built Around Flow, Drainage, and Property Protection
Storm drain systems are there to move runoff safely and efficiently. When they stop working, the damage does not always stay limited to the drain itself. Water can collect where it should not, overflow across pavement, undermine soil, affect foundations, and create long-term site problems.
That is why we approach storm drains through inspection first. We want to understand whether the problem is debris buildup, inlet blockage, pipe damage, collapse, corrosion, poor drainage design, or a larger excavation and replacement issue.
This page should act as the main storm drain hub for Denver Sewer & Water and route users into the right child service, not bury the real service path under generic plumbing copy.
Storm Drain Services We Evaluate and Perform
Storm Drain Repair
Repair for damaged, leaking, blocked, deteriorated, or failing storm drain pipes and components.
Storm Drain Cleanout
Cleanout service to remove debris, sediment, buildup, and blockage so the system can move runoff more effectively.
Storm Drain Scope and Video Inspection
Camera-based inspection to identify blockages, cracks, leak points, collapse, or other internal drain conditions before choosing the repair path.
Storm Drain Replacement and Installation
Replacement or new installation when the existing system is too damaged, outdated, undersized, or unreliable for a durable repair.
Storm Drain Maintenance
Ongoing maintenance support to help prevent clogs, preserve flow, and reduce the risk of flooding and property damage.
Explore Storm Drain Maintenance
Storm Drain Excavation
Excavation-based access and repair for lines or site conditions that cannot be addressed through cleaning, maintenance, or limited repair alone.
Emergency Storm Drain Repair
Urgent repair support when storm drainage failure is actively affecting property conditions, flooding, or site safety.
What a Storm Drain System Usually Includes
Storm drain systems often include inlets, catch basins, underground pipes, and discharge points that work together to move runoff away from surfaces and structures.
When one part of the system becomes blocked, damaged, or undersized, the result can show up as flooding, slow drainage, standing water, or visible deterioration elsewhere on the property.
Who This Page Should Speak to
This page should work for commercial properties, retail centers, industrial sites, apartment communities, parking lots, HOAs, municipal-type properties, and residential properties with real drainage-system needs.
Storm drain intent often comes from users dealing with site drainage, paved-surface runoff, catch basin issues, or repeated flooding rather than from standard indoor plumbing searches. The page should reflect that difference.
Common Signs a Storm Drain System May Need Service
- Standing water that lingers after rain or snowmelt.
- Overflowing inlets or catch areas during storms.
- Water collecting near foundations, curbs, or paved surfaces.
- Visible debris, sediment, or blockage at the drain opening.
- Erosion, washout, or water damage near the drainage path.
- Recurring flooding in parking lots, drive lanes, or low areas.
- Suspected cracked, collapsed, or deteriorated storm drain pipe.
- Drainage issues tied to older infrastructure or site changes.
If these problems sound familiar, inspection is usually the safest next step before deciding on cleaning, repair, or replacement.
Do You Need a Cleanout, a Repair, or Full Replacement?
Cleanout May Be the Right Move When
- The main issue is debris, sediment, buildup, or a blockage that is limiting water flow.
- The structure of the drain is still in serviceable condition.
- Maintenance has been delayed and the system needs to be restored to normal flow.
Replacement May Be the Better Move When
- The system is broadly deteriorated, repeatedly failing, poorly sized, or too compromised for a durable repair.
- The property needs a more dependable long-term drainage solution.
Cleanout May Be the Right Move When
- The main issue is debris, sediment, buildup, or a blockage that is limiting water flow.
- The structure of the drain is still in serviceable condition.
- Maintenance has been delayed and the system needs to be restored to normal flow.
This page should help users understand that not every storm drain issue is solved by cleaning, and not every storm drain issue requires a full rebuild. Diagnosis matters first.
Routine Maintenance and Inspection Can Prevent Bigger Drainage Failures
Storm drain systems often fail gradually before they fail dramatically. Debris accumulates, inlets become restricted, runoff patterns change, and hidden pipe problems develop below the surface.
Competitors that rank well in this space often explain maintenance clearly, and for good reason. Regular cleanout and periodic camera inspection can help identify drain issues before they become flooding, erosion, or expensive property-damage problems.
Excavation When Necessary. Replacement When the System Calls for It.
Some storm drain issues can be handled through cleaning or targeted repair. Others require excavation because the pipe is collapsed, access is limited, the grade is wrong, or the system needs larger or more complete replacement work.
For development and redevelopment projects in Denver, owners may also need adequate storm and sanitary sewer services planned and submitted to meet City criteria. That does not mean every service call becomes an engineering project, but it does mean serious drainage work can overlap with broader site and permitting requirements on the right properties.
How Our Storm Drain Process Works
Understand the Drainage Problem
We start with what the property is experiencing, where the runoff is failing, whether flooding is active, and what areas of the site are affected.
Inspect the System
We evaluate whether the issue points toward blockage, debris buildup, structural damage, localized repair, excavation, or broader replacement.
Recommend the Right Path
We explain whether the next step is cleanout, repair, scope inspection, maintenance, excavation, or replacement and installation.
Complete the Work
Once the scope is clear, the work moves forward with a focus on restoring drainage performance and protecting the property from recurring water problems.
Why a Specialist Matters for Storm Drain Work
Stormwater Problems Are Not Generic Plumbing Problems
This page should make it clear that storm drain issues are about runoff management, flooding prevention, site drainage, and underground stormwater infrastructure.
Property Damage Risk is Real
Users want to know the contractor understands water accumulation, erosion, drainage failure, and the larger property consequences of letting the issue continue.
Commercial and Site-intent Users Need Confidence
Many storm drain jobs are tied to larger site drainage concerns, parking lots, multifamily properties, or commercial spaces. The page should feel capable enough for those users while still serving residential drainage needs.
Routing Into the Right Child Service Matters
This hub should guide users into cleanout, repair, inspection, maintenance, excavation, replacement, or emergency service without making them work through clutter to find the right path.
Why Trust Matters on Storm Drain Projects
Storm drain work matters most when water is not going where it should. Property owners want a contractor who understands urgency, diagnosis, and the larger consequences of a failed drainage system.

Frequently Asked Questions
What is the Difference Between a Storm Drain and a Sanitary Sewer?
Storm drains move rainwater, snowmelt, and surface runoff, while sanitary sewers carry wastewater from sinks, toilets, and drains. In Denver, these systems are separate.
What Causes Storm Drains to Fail?
Common causes include debris buildup, sediment, blocked inlets, cracked or collapsed pipes, corrosion, poor drainage flow, and systems that are too damaged or undersized for the runoff they handle.
Do I Need a Cleanout or a Repair?
That depends on whether the problem is mainly buildup and blockage or whether the system has structural damage that needs a true repair or replacement path.
Can Storm Drains Be Inspected Before Repair?
Yes. Scope and video inspection help identify the internal condition of the drain so the repair path is based on real findings instead of guesswork.
Do You Handle Emergency Storm Drain Issues?
Yes. If active flooding, severe blockage, or drainage failure is affecting the property, urgent storm drain service may be needed.
Do Storm Drain Projects Ever Involve Excavation or Replacement?
Yes. Some systems are too damaged, too old, or too compromised for a simple cleanout or limited repair and need excavation or more complete replacement work.
