Quick Guide: Sewer Line From House to Street Essentials

  • Your Responsibility: Inside your property lines
  • Sewer Company’s Role: Lateral drains and main sewers outside your property
  • Regular Maintenance: Essential to prevent clogs and backups
  • When Issues Arise: Know where your cleanout is located

Have you ever wondered why your sinks are draining slowly or why there’s an unpleasant odor coming from your drains, even when you’ve tried every home remedy out there? The issue could lie within your sewer line—the unsung hero of your home’s plumbing system. Understanding the basics of your sewer line, from your house to the street, and recognizing the importance of its maintenance, could save you from a plumbing catastrophe.

Sewer lines are crucial for transporting waste water from your home to the main city sewers or septic tanks. However, these lines are often out of sight and thus out of mind until a problem emerges. Like any other part of your home, your sewer system requires regular checks and maintenance to run smoothly. Knowing what parts of the sewer line you’re responsible for and what signs to look for can help you prevent or quickly address potential issues.

In this guide, we’ll walk you through the essentials of sewer lines, from understanding your responsibilities as a property owner to the importance of regular maintenance. We aim to give you peace of mind, knowing your sewer system is functioning correctly and efficiently.

Understanding Your Responsibility

When it comes to sewer lines from house to street, it’s crucial to know where your responsibility begins and ends. This knowledge is not just about fixing problems but also about preventing them.

Property Boundaries

Your property boundary is the line that divides your land from your neighbors and public spaces. When it comes to sewer lines, you’re generally responsible for the pipes within these boundaries. This means if a blockage or damage occurs here, it’s up to you to fix it.

Lateral Drains

Lateral drains are the pipes that carry wastewater away from your home to the main sewer. These are typically located outside your property boundary. In most cases, the sewerage company is responsible for these, not you. However, it’s good to know where they are in case of a sewer-related issue.

Sewer Mains

Sewer mains are the large pipes that transport sewage from numerous homes to the wastewater treatment plants. These are almost always the responsibility of the local sewerage company. Your home’s sewer line connects to these mains, but the main itself is public property.

Private vs. Public Ownership

Understanding the difference between private and public ownership of sewers is critical. Most sewers are publicly owned, but there can be exceptions. If you’re part of a homeowners association (HOA), for instance, there might be different rules.

Key Takeaways:

  • Inside your property? You’re likely responsible.
  • Lateral drains and sewer mains? Typically, that’s on the sewerage company.
  • Know your property boundaries to pinpoint where your responsibilities lie.
  • Check with your local sewerage company or HOA for specifics in your area.

At Sanz Plumbing, we’re here to help you navigate these responsibilities. Whether it’s maintenance, repair, or just understanding your sewer line from house to street, we’ve got you covered. Regular maintenance is key to preventing sewer line issues, saving you from costly repairs down the line.

How Sewer Lines Work

Pipes, Laterals, Main sewer lines, Wastewater treatment, Gravity and pump stations


When we talk about the journey from your home to the city sewers, it’s a story of engineering marvels, mostly hidden from our daily view. Let’s break it down into simpler terms.

Pipes

Every time you flush a toilet, drain a bathtub, or wash dishes, the water and waste travel through small pipes in your house. These pipes are like the veins of your home’s plumbing system, carrying waste away to a larger vessel.

Laterals

The larger vessel is what we call a lateral. This is a pipe that connects your home’s plumbing to the main sewer line under the street. Think of it as the highway on-ramp; your waste is merging into the main traffic flow.

Main Sewer Lines

The main sewer line is the big road, the interstate of waste. It’s a large pipe running under your street that collects wastewater from all the homes and businesses in the area. This is where everyone’s waste travels together, heading towards a common destination.

Wastewater Treatment

The destination for all this waste is the wastewater treatment plant. Here, the water is cleaned and treated through various processes until it’s safe to be released back into rivers, oceans, or used for irrigation.

Gravity and Pump Stations

How does all this waste keep moving? Mostly, it’s thanks to gravity. The system is designed so that pipes slope downward towards the treatment plant. But when gravity isn’t enough, pump stations step in. These stations pump waste over hills or any obstacle that gravity can’t handle on its own.

At Sanz Plumbing, we understand the intricacies of how sewer lines work. From the initial flush in your home to the treatment of wastewater, every stage is crucial for maintaining a healthy, functioning sewer system. Regular maintenance and swift repairs when issues arise are key to preventing backups and ensuring the smooth operation of this unseen, yet vital infrastructure.

While the journey from sewer line from house to street might not be something you think about daily, it’s an essential process that keeps our homes clean and our communities healthy. If you suspect any issues with your home’s sewer line, don’t hesitate to reach out to us. We’re here to ensure everything flows smoothly, without any hitches.

Common Sewer Line Issues and Solutions

When it comes to the sewer line from house to street, a few common problems can really make a mess of things. However, with the right know-how and a bit of preventative maintenance, many of these issues can be managed or even avoided. Let’s dive into some of the most common troubles and how to solve them.

Clogs

Clogs are a homeowner’s nightmare, often caused by flushing things that don’t belong in the pipes, like wipes, grease, or other non-biodegradable items. The solution? Be mindful of what goes down your drains. In cases where a clog has already formed, we at Sanz Plumbing utilize specialized tools to clear the blockage safely and efficiently.

Tree Roots

An underground invader, tree roots, can find their way into your sewer lines, causing damage and blockages. This usually happens when there are cracks or leaks in the pipes. A preventive measure is to plant trees away from your sewer lines. However, if roots have already infiltrated, we might need to use techniques like hydro jetting to remove the roots and repair any damage they’ve caused.

Blockages

Similar to clogs but often more severe, blockages can occur from an accumulation of debris or from objects that should not have been in the sewer in the first place. Regular maintenance, including professional cleaning, can keep these blockages at bay.

Jet Blasting

For tough clogs and blockages, jet blasting is a powerful solution. It involves high-pressure water being sent through the pipes to clear out anything in its path. This method is effective for removing grease, sludge, and even tree roots.

CCTV Inspections

One of the most innovative ways to diagnose sewer line issues is through CCTV inspections. This involves sending a camera down your pipes to get a real-time view of what’s happening inside. It helps us identify problems like cracks, blockages, and root intrusion without having to dig up your yard. As a Reddit user mentioned, CCTV inspections are essential for ensuring no blockages or tree roots are causing problems unseen .

Regular Maintenance

The best way to avoid sewer line issues is through regular maintenance. This includes professional inspections and cleanings to ensure everything is in working order. At Sanz Plumbing, we stress the importance of preventative measures to save our clients from costly and inconvenient repairs down the line.

In summary, while sewer line issues from house to street can be a hassle, understanding the common problems and their solutions can make all the difference. Whether it’s being careful about what goes down the drain, planting trees away from sewer lines, or scheduling regular maintenance, each step you take can help keep your sewer system running smoothly. And remember, if you ever run into trouble, we’re just a call away, ready to help with our expertise and state-of-the-art equipment.

When to Contact the City

Understanding when it’s time to reach out to the city about your sewer line from house to street can save you a lot of headaches. Let’s break down the scenarios where the city is responsible and when you might need to get them involved.

City Responsibility

First off, the city takes care of the main sewer line. This is the big pipe that carries all the waste and water away from your neighborhood to the treatment plant. If there’s a problem here, it’s on the city to fix it.

Upper and Lower Laterals

Your sewer system has two main parts: the upper lateral and the lower lateral. The upper lateral runs from your house to the edge of your property (usually up to the sidewalk), and the lower lateral goes from the edge of your property to the main sewer line under the street.

  • Upper Lateral: This is your responsibility. It’s everything from your home up to where your property ends.
  • Lower Lateral: Here’s where it gets tricky. Even though this part isn’t on your property, if there are issues like clogs or tree roots coming from your side, you might still be responsible.

Sidewalk to Street

If you’re noticing problems in the section from the sidewalk to the street, figure out if it’s an upper or lower lateral issue. For lower lateral problems, you might still need to take action or work with the city for a fix.

Private Drain Repair Program

In some cases, like in Chicago, the city offers a Private Drain Repair Program. If your sewer drain tiles are broken under the public way (from the city sidewalk to the center of the street), the city might repair them at no cost to you. However, conditions apply:
– A licensed sewer contractor must verify the break via rod or video inspection.
– The contractor then schedules a review by a city sewer inspector.

Contacting Water Management

If you suspect the issue falls under city responsibility or if you’re eligible for programs like the Private Drain Repair Program, your next step is to contact your local water management or sewer department. Keep their contact info handy for quick access in emergencies.

Remember, if you’re unsure whether a problem is your responsibility or the city’s, it’s always best to reach out to professionals. At Sanz Plumbing, we can help diagnose the issue, advise on the best course of action, and even assist in liaising with city officials if necessary. Our goal is to ensure your sewer line from house to street is functioning correctly, giving you peace of mind.

Preventative Measures and Maintenance

Taking care of your sewer line from house to street may not be the first thing on your mind every day, but it’s crucial for avoiding larger, more expensive problems down the road. Here’s how to stay ahead:

Regular Clearing

It’s wise to have your sewer lines cleared out regularly. This doesn’t just mean when there’s a blockage. Regular clearing can prevent blockages from happening in the first place. Think of it like changing the oil in your car; it’s routine maintenance that keeps things running smoothly.

CCTV for Inspection

Using CCTV for sewer line inspections is a game-changer. This technology allows us to take a close look inside your sewer lines without any digging or guesswork. As one plumber on Reddit puts it, *”Regular clearing out via jet blasting plus routine maintenance and CCTV of pipes to ensure no blockages or tree roots”* . It’s a non-invasive way to spot potential issues before they become big problems.

Importance of Licensed Plumbers

When it comes to sewer lines, not just any fix will do. You need someone who knows what they’re doing. Licensed plumbers, like us at Sanz Plumbing, have the training and experience to handle these matters effectively. We understand the complexities of sewer systems and how to fix them properly.

Frequently Asked Questions about Sewer Lines

When it comes to understanding the sewer line from house to street, there are some common questions we encounter. Let’s dive into these.

Who is responsible for sewage pipes?

The simple answer is: It depends on where the pipe is located. If it’s within your property boundaries, it’s usually your responsibility. This includes all the pipes that connect your house to the main sewer line. However, the lateral drains and the main sewer lines, which typically run under public streets, are usually the responsibility of your local sewerage company. There are exceptions, especially if the sewer lines are privately owned or unadopted.

How do I clean my sewer line from my house to the street?

Cleaning your sewer line is crucial for maintaining a healthy plumbing system. Here’s a simplified guide:

  1. Loosen the cap on the drain pipe carefully to avoid any sudden release of sewage.
  2. Open the cap and let the buildup drain out. Be prepared for the possibility of foul water.
  3. Feed an auger cable into the drain pipe to reach and break apart the clog.
  4. Run the auger until you feel the blockage clear. It’s wise to continue a bit beyond this point to ensure you’ve completely addressed the issue.
  5. Hose down both the pipe and the auger cable to clean away any remaining debris.

It’s a good idea to wear protective clothing during this process to avoid any health hazards.

What is the main sewer line in a house called?

The main sewer line is often simply referred to as the mainline. It’s the primary pipe that carries waste and wastewater from your home to the municipal sewer system or your septic tank. All your home’s drains connect to this mainline. Knowing where your house’s cleanout is located can be crucial for addressing any backups or issues quickly and efficiently.


Maintaining your sewer line from house to street is essential to prevent inconvenient or costly problems down the line. At Sanz Plumbing, we’re here to help with any questions or concerns you might have about your home’s plumbing system. Whether it’s regular maintenance or emergency repairs, we’ve got you covered.


Understanding the ins and outs of your home’s sewer line is more than just practical knowledge—it’s your first line of defense against potential plumbing disasters. The journey of wastewater from your house to the street and beyond is a complex one, but knowing a bit about it can save you time, money, and headaches.

Knowledge is Power

When it comes to the sewer line from house to street, the more you know, the better equipped you are to prevent issues before they arise. Understanding the basic structure and function of your sewer line, including the lateral sections and their maintenance requirements, empowers you to spot early warning signs of trouble.

Being Prepared

Preparation means having a plan before problems occur. This includes knowing who to call when you suspect a sewer line issue, whether it’s us at Sanz Plumbing or your city’s water management department for concerns beyond your property line. Being prepared also means regular inspections and maintenance, which can catch small problems before they turn into big ones.

Knowing Your Rights and Responsibilities

As a property owner, it’s crucial to understand where your responsibilities begin and end concerning the sewer line. Knowing the difference between the upper and lower laterals, for instance, can clarify what parts of the sewer line you’re accountable for and what parts fall under city jurisdiction. This knowledge not only helps in addressing issues more efficiently but also in navigating discussions with insurance providers or city officials.
