Why Do Colorado Springs Homes Get Sewer Line Root Intrusion?

Guides / Sewer Lines

A dry climate turns your sewer into a water source

Colorado Springs averages far less rainfall than the trees in our older neighborhoods would naturally support. Those trees survive by sending roots toward dependable moisture, and a sewer lateral is the most dependable moisture on the lot: warm, nutrient-rich, and running every single day. Where a joint or hairline crack releases vapor into the soil, roots grow straight at it.

The pipe under most older Springs homes invites it

Homes built before roughly 1970 in the Old North End, Patty Jewett, Knob Hill, Ivywild, and the Westside were plumbed with vitrified clay or cast iron. Clay comes in short sections with mortared bell joints, and mortar fails long before the clay does. Cast iron corrodes at the hub. Either way, a fine root hair only needs a gap the width of a business card. Once inside, it thickens into a rope and then a mat that strains everything passing through.

Expansive soil makes the gaps

Front Range clay soil swells when wet and shrinks when dry. That seasonal movement works joints apart and creates offsets and low spots. So the soil that stresses foundations here is also what opens the doors roots walk through. It's the reason two identical houses on the same block can have wildly different sewer histories.

The trees most often involved

• Cottonwoods — the most aggressive water seekers in the region
• Siberian and American elms — dense, fibrous root mats
• Silver maple — shallow, fast-growing, opportunistic
• Willows — planted near low spots, which is where laterals often sag
• Junipers and lilac hedges — smaller, but frequently planted right over the lateral run

What root intrusion feels like from inside the house

Roots rarely block a line overnight. The pattern is gradual: toilets flush slower, the basement floor drain gurgles when the washer empties, then a backup after a big laundry day or a houseful of guests. If several fixtures slow down together, you're looking at the main, not a branch. More symptoms in 5 signs your main sewer line is clogged.

How root removal actually works

There are two real tools, and the difference matters:

• Cabling with a cutting head shears the root mass and restores flow. It's fast and often the right emergency answer, but it leaves root stubs at the joint that regrow.
• Hydro jetting with a root nozzle cuts roots back to the pipe wall and flushes the debris out of the line instead of leaving it downstream. Regrowth takes considerably longer.

Either way, a camera inspection afterward is what tells you whether you have a maintenance situation or a repair situation. We show you the footage on screen rather than describing it.

When cleaning stops being the answer

If the camera shows a cracked hub, a separated joint, a crushed section, or a belly holding standing water, roots will keep coming back no matter how well the line is cleaned. At that point the honest recommendation is a spot repair or replacement of the failed section — see excavation and sewer repair. We never suggest digging without showing you why first.

Keeping roots out

• Put root-prone lines on a 12–24 month cleaning interval instead of waiting for a backup
• Don't plant cottonwood, elm, willow, or silver maple over or near the lateral run
• Have the lateral located and marked so future landscaping stays clear of it
• Scope before you buy — a pre-purchase camera inspection on any pre-1980 Springs home is the cheapest insurance in the transaction
