How Dry Colorado Winters Lead to Sewer Line Problems (and What Homeowners Can Do About It)

cracked sewer line in CO springs full of tree roots

Most Colorado homeowners think about winter plumbing in terms of frozen pipes. That’s a real concern, sure, but there’s another seasonal threat that gets almost no attention: drought.

While Colorado winters are often brutally dry, this past winter was one of the hottest, driest, and least snowy on record. The lack of moisture creates the perfect conditions for a sneaky, slow-moving kind of sewer line damage.

At Big Cat Plumbing, Heating & Cooling, we see this play out every year, and most homeowners don’t connect the dots until there’s already a problem.

Here’s what’s actually happening underground, and what you can do about it.

Why Dry Winters in Colorado Create Sewer Line Problems

When Colorado goes through a dry winter with below-average snowpack, the soil loses most of its moisture content. That might not sound like your problem, but your trees notice.

Tree roots are always searching for water. In normal conditions, they spread through the soil and find it readily enough. But during extended dry spells, the soil around them becomes almost completely desiccated. Your sewer line, on the other hand, carries warm, moisture-rich wastewater 24 hours a day. To a thirsty root system, it’s basically a beacon.

Roots will travel several feet to reach a reliable water source. And once they find the tiny cracks or loose joints that exist in virtually every sewer line, especially older ones, they don’t stop.

How Tree Roots Get Into Sewer Lines

It doesn’t take a massive crack for a root to get started. Hair-thin root tips can push through the smallest gaps in pipe joints or hairline fractures in the pipe wall. Once they’re in, they absorb water and expand. A root that started as a thread can become a thick mass that fills the interior of your pipe.

From there, it acts like a net. Toilet paper, grease, and other waste catch on the roots and build up over time. What started as a minor intrusion becomes a significant blockage. If the root growth goes unchecked long enough, the physical pressure can crack or collapse the pipe entirely.

This process moves slowly, which is part of why it’s so easy to miss until it becomes an emergency.

Warning Signs You Shouldn’t Ignore

Your plumbing will usually give you some advance notice before things get truly bad. Watch for:

Slow drains throughout the house (not just one fixture, which typically indicates a local clog)
Frequent backups in toilets, tubs, or floor drains
Gurgling sounds coming from toilets or drains after flushing
Sewage odors inside the house or near your yard
Unusually lush or green patches of grass, even during dry conditions, which can indicate a slow leak feeding the soil above your sewer line

Any one of these could point to root intrusion or another form of sewer line damage. Multiple symptoms together are a clear signal to get an inspection.

Why Colorado Springs Homes Are Particularly Vulnerable

A few things stack up against Colorado Springs homeowners specifically.

First, the soil. Much of the region has clay-heavy soil that absorbs and releases moisture unevenly. When it dries out, it shrinks and shifts. That movement puts stress on buried pipes and can open up new cracks or worsen existing ones.

Second, the trees. Many established neighborhoods in and around Colorado Springs have mature landscaping. Those gorgeous old cottonwoods and elms have root systems that extend far beyond the canopy, often right through the area where your sewer line runs.

Third, freeze-thaw cycles. Even in dry winters, Colorado sees significant temperature swings. Water gets into small cracks, freezes, expands, and widens them, making it easier for roots to find a way in when spring arrives.

Finally, aging infrastructure. Parts of Colorado Springs have homes with original clay or cast-iron sewer lines that are decades old. These materials are far more susceptible to root intrusion and cracking than modern PVC pipe.

What You Can Do to Prevent Problems

You don’t need to wait for symptoms to take action. A few practical steps go a long way:

Get a sewer inspection every 2–3 years, or annually if you have mature trees near your main line. A camera inspection takes the guesswork out entirely.
Schedule sewer cleaning if you haven’t had one recently. Hydro jetting can clear early-stage root intrusion and debris buildup before it becomes a blockage.
Be mindful of what you’re planting. If you’re landscaping near your sewer line, stick to shallow-rooted plants and keep large trees at a safe distance.
Consider root barriers if you have large trees close to the line, especially during a renovation or yard project when the ground is already being disturbed.
Watch what goes down the drain. Grease, wipes (even so-called flushable ones), and other debris give roots something to catch on once they’re inside the pipe.

When It’s Time to Call a Professional

DIY drain cleaners and augers have their place, but they don’t solve root intrusion. They might clear a clog temporarily, but the roots stay in the pipe and keep growing. If you’re dealing with recurring clogs or multiple slow drains, that’s a sign the problem is deeper than a standard fix can reach.

A professional camera inspection lets a plumber see exactly what’s going on inside your drain and sewer system and pinpoint the issue without digging up your yard first. From there, the right solution might be hydro jetting, sewer lining (a trenchless repair that restores the pipe from the inside), or full replacement if the damage is severe. Getting the diagnosis right early keeps the cost of repairs as manageable as possible.

If you’re dealing with a sudden backup or sewage smell, don’t wait. That’s a situation that calls for emergency plumbing service right away.

FAQs About Dry Weather and Sewer Lines

Can drought really damage my sewer line?

Drought doesn’t damage the pipe directly, but it drives root systems toward sewer lines aggressively. The physical damage comes from the roots themselves as they grow inside and around the pipe.

How fast do tree roots grow into pipes?

It varies by tree species and soil conditions, but root intrusion typically develops over months to years. That said, once roots are established inside a pipe, they can cause a serious blockage relatively quickly.

Are newer homes at risk too?

Newer homes with PVC pipes are more resistant, but not immune. Joints can still develop gaps over time, especially if soil shifting is a factor. Any home with mature trees nearby carries some risk.

How often should I have my sewer line inspected in Colorado?

Every 2–3 years is a reasonable baseline. If you have large trees, older pipes, or a history of slow drains, an annual inspection is worth it for the peace of mind alone.

Don’t Wait for a Backup to Find Out There’s a Problem
