Storm Drain Replacement and New Drainage Installation
An independent, licensed plumbing contractor. Not affiliated with Denver Water or the City and County of Denver.
Storm drain replacement and installation covers putting in new private drainage or replacing a run that is beyond repair: catch basins, area drains, trench drains, downspout collection, and the buried pipe carrying it all to a discharge point that can actually take it. The design question comes before the pipe question, always.
- New area drains, trench drains, and catch basins.
- Downspout collection and buried discharge lines.
- Full replacement of runs beyond repair.
- Catchment sized before pipe is specified.
- Discharge point confirmed viable before work starts.

When Is New Drainage the Right Answer?
When water has somewhere it needs to go and no path to get there. A window well that floods, a below-grade entry that ponds, a lawn that holds water for days after a storm, or a downspout discharging against a foundation are all problems that buried drainage solves properly.
It is not always the right answer. Water sitting against a foundation because the ground slopes toward the house is a grading problem, and correcting the grade fixes it more cheaply and more permanently than installing pipe to carry away water that should never have arrived. We will tell you when that is the case.
(720) 935-6221Situations that call for new drainage
- Window wells and areaways that flood in storms.
- Downspouts discharging at the foundation.
- Low areas that hold water for days.
- Patios and driveways that shed water toward a building.
- Existing runs crushed or silted beyond economic repair.
- New hardscape that has changed where water goes.
How We Diagnose It
How the Discharge Point Decides the Design
Water has to leave. On a sloping site that can mean daylighting the line to a lower point on the property, which is the simplest and most reliable option. On a flat site there may be no lower point, and then the choices narrow to a connection into a public storm system where one is available and permitted, or a dry well sized to absorb the volume.
Each of those has limits. Daylighting needs fall. A storm connection needs both proximity and permission. A dry well needs soil that will actually absorb, which in much of the metro's clay it will not at the rate people assume. Establishing which of these is genuinely available comes before anything is designed.
Discharge options and their constraints
- Daylight to a lower point: needs continuous fall across the run.
- Public storm connection: needs availability and permission.
- Dry well: needs soil with real absorption capacity.
- Existing private run: needs spare capacity in that run.
How a Drainage Installation Runs
- 1
Walk the site and define the catchment
Where the water comes from, how much surface feeds each point, and where it currently ends up.
- 2
Establish the discharge
Confirm a viable, legal, and physically capable place for the water to go before designing anything upstream of it.
- 3
Design and size
Collection points positioned where the water actually sits, pipe sized to the catchment, fall set across the whole run.
- 4
Install, test, restore
Trench, bed, lay to grade, connect, water test, then compacted backfill and surface restoration.
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”
“We had an underground water valve break on a Saturday. No fun and expensive to fix regardless of the repair company. Nevertheless, greatly apprecia”
“Very direct and to the point. Extremely efficient and professional.”
What Drives Installation Cost
Run length, number of collection points, surface type across the route, and what the discharge solution has to be. A short daylight run across open turf is a modest project. A long run across finished hardscape ending in a dry well is a substantially larger one.
The cost that surprises people is restoration, not pipe. Cutting and replacing concrete, pavers, and mature planting is frequently the larger share of a drainage installation on a finished property.
