Sewer Line Installation

Sewer Line Installation

A reliable sewer line isn’t just a convenience, it’s a necessity. Every time you flush a toilet, run a sink, or use your washing machine, wastewater travels through your sewer line and out to the city’s main system. If that line isn’t installed properly, the result can be sewage backups, costly property damage, and serious health risks.

At Mighty Plumbing, Heating, Air & Electric, we provide professional sewer line installation services across the Greater Denver Area. As part of our full range of Plumbing Services in Denver, CO, we make sure every sewer system is safe, efficient, and designed to last for decades. Whether you’re building a new home, remodeling, or replacing an outdated line, our team ensures your sewer system is safe, efficient, and designed to last for decades.

Building or Remodeling? You May Need a New Sewer Line

Sewer lines aren’t something homeowners often think about until there’s a problem, but they play a central role in your home’s plumbing system. Installation is required in several common scenarios:

  • New home construction – Every house needs a properly designed sewer connection to tie into the municipal system.
  • Major remodels or additions – Adding a bathroom, laundry room, or new kitchen may require new or rerouted sewer lines.
  • Upgrading outdated materials – Older homes may still rely on clay, cast iron, or Orangeburg (tar-paper) pipes, all of which are prone to collapse.
  • Persistent clogs or backups – If drain cleaning doesn’t solve the issue, the problem may be with the sewer line itself. In these cases, professional Sewer Line Repair may be needed to restore proper flow before a full replacement becomes necessary.
  • Tree root intrusion – If roots keep invading your line, replacement with modern, root-resistant materials may be the best solution.
 

Customer Tip: If your home is more than 40 years old and has never had its sewer system updated, it’s a good idea to have it inspected, even if you haven’t noticed issues yet. Preventative replacement can save thousands in emergency costs later.

New Sewer Line Installation

What’s Included in Our New Sewer Line Installation Services

Every property has its own unique needs, and sewer line installations are no exception. We tailor each project to your circumstances and goals, offering modern solutions designed for long-term reliability.

Our sewer line installation services include:

  • New Home Construction — We design and install complete sewer systems for newly built homes, taking into account terrain, soil conditions, and local codes.
  • Remodels & Additions — Need a new bathroom, kitchen, or laundry room? We can reroute or extend sewer lines to accommodate new fixtures and layouts.
  • Trenchless Installation Options — Methods like pipe lining (CIPP) or pipe bursting allow us to renew or replace sewer lines without full excavation, which means minimal disruption to landscaping, driveways, or your yard.
  • Traditional Excavation — When trenchless methods aren’t viable, our team performs careful excavations and restores the area afterward—ensuring both proper installation and thoughtful property care.
  • Sewer Rerouting — If your existing lines are near tree roots, foundations, or landscaping you’d rather protect, we can reroute them to prevent future issues.
  • Upgrading Old Piping — We replace outdated materials such as clay, cast iron, or Orangeburg with modern, long-lasting options like PVC or HDPE piping. This process is similar to Repiping, ensuring your home benefits from stronger, more reliable plumbing throughout.
  • Inspection & Testing — Every new installation includes a camera inspection and pressure test to verify code compliance and confirm everything is flowing correctly before we finalize the project.
 

Customer Tip: If you’ve had recurring sewer problems in the past, or you’re concerned about disturbing your lawn, trenchless technology is often the ideal choice. It extends the life of your system and keeps your property mostly intact.

Why Professional Sewer Line Installation Matters

Skipping the right installation process for your sewer line can lead to serious problems down the road, both in terms of cost and health. These include:

  • Sewage Backups Inside Your Home — Raw sewage can overflow into bathrooms or basements, creating expensive cleanup and health hazards.
  • Foundation Damage — Leaks degrade soil around your foundation, potentially causing cracks or structural shifts.
  • Root Intrusion — Poor installation or non-sealed joints can allow tree roots to invade, clogging or breaking the line.
  • Health Risks — Prolonged exposure to untreated wastewater can lead to mold, mildew, and illness.
  • Code Violations — Improper installations may lead to failed inspections or invalidated insurance coverage.
  • High Future Costs — A line not installed correctly often requires a full replacement much sooner than normal.
 

Customer Tip: Many insurance policies don’t cover damage that stems from poor installation or neglect. Hiring professionals ensures both safety and financial protection.

How to Install a Sewer Line

The Real Value of a Correct Sewer Line Installation

A properly installed sewer line isn’t just “set it and forget it”, it’s an investment that pays off in reliability, durability, and long-term value.

Here’s what you gain:

  • Long-Term Reliability — With modern materials and professional installation, sewer lines can last 50–100 years. PVC lines, for example, have lifespans of 80–100 years under favorable conditions.
  • Stronger, Modern Materials — PVC and HDPE resist corrosion and tree roots, offering smoother flow and less wear over time.
  • Optimized System Design — Proper sizing ensures your system handles peak demand without backups.
  • Fewer Plumbing Emergencies — Well-installed lines significantly reduce the chance of constant clogs or backups.
  • Compliance with Building Codes — Avoid fines, failed inspection paperwork, or issues during home sales.
  • Added Property Value — Buyers value modern plumbing systems, they show the home is well maintained and safer.
 

Customer Tip: When upgrading, ask about adding a backwater prevention valve. It’s an extra layer of defense that helps prevent sewage backups during heavy rain or municipal system overload.

Sewer Line Installation FAQ

Most installations are completed in 1 to 5 days, depending on the scope of the job, property access, and whether we use trenchless technology or traditional excavation. Trenchless methods are faster and less invasive, while excavation may take longer but is sometimes necessary for older systems.

PVC (polyvinyl chloride) and HDPE (high-density polyethylene) are industry-standard materials today. They’re strong, flexible, and highly resistant to corrosion, tree roots, and environmental wear. These materials also have long lifespans, often lasting 50 to 100 years when installed correctly.

Yes. Sewer line work is a regulated process that requires permits and inspections to ensure everything meets local building codes. The good news? We handle all of the permitting and coordinate inspections on your behalf.

Not always. If your property qualifies for trenchless installation, we can often replace or install your line with minimal disruption, just a couple of small access points. For traditional excavation, some digging is required, but we restore the area after the job is done and can coordinate with landscapers if needed.

Some signs that full replacement is a better solution include:

  • Recurring backups or slow drains throughout the home

  • Foul odors or visible sewage near the foundation or yard

  • Known use of outdated materials like clay or Orangeburg pipe

  • Crushed, collapsed, or severely corroded sections
    We’ll conduct a camera inspection to evaluate the condition and recommend the right path forward.

No. Sewer installation is not a DIY job, it requires specialized tools, engineering knowledge, permits, and code compliance. Improper installation can lead to dangerous backups, code violations, or even fines. Our licensed professionals ensure the job is done safely and correctly.

When installed with modern materials and maintained properly, a new sewer line can last 50 to 100 years. We use high-quality piping and proven methods to ensure longevity and durability.

Yes. If your current line has failed and you’re dealing with raw sewage, no drainage, or a health risk, we can fast-track your emergency installation to restore your system and protect your home.

Costs vary based on factors like:

  • The length and depth of the line

  • Whether trenchless or excavation methods are used

  • Material type (PVC, HDPE, etc.)

  • Local permitting requirements
    We always provide transparent estimates upfront and walk you through every option available.
