How Long Does It Take to Replace a Sewer Line?

Table of Contents

TLDR

On average, replacing a sewer line takes 1 to 3 days. The exact timeline depends on the method used, pipe length, soil conditions, permits, and whether the work is an emergency or planned. Complex projects in Louisiana may take a week or longer.

What Sewer Line Replacement Involves

What Sewer Line Replacement Involves

Sewer line replacement is more than digging and swapping out a pipe. The process involves:

  • Inspection with a sewer camera to confirm damage

     

  • Applying for permits from the local authority

     

  • Marking underground utilities to avoid hazards

     

  • Excavation or trenchless access setup

     

  • Removing the damaged pipe

     

  • Installing the new sewer line

     

  • Inspection from the city or parish in Louisiana

     

  • Backfilling and restoring the yard or driveway

     

Many guides skip over permits and inspections. In Louisiana, these steps are mandatory and add time. Sewer Solutions handles this process to keep projects moving without unnecessary delays.

Average Timeline for Sewer Line Replacement

Average Timeline for Sewer Line Replacement

One-Day Jobs

Some replacements are finished in a single day. This is common with:

  • Trenchless pipe bursting or lining
  • Short sections of pipe
  • No major obstacles like driveways or heavy landscaping

Two to Three Days

Most residential sewer replacements fall into this range. Factors include:

  • Average pipe length of 40 to 60 feet
  • Moderate digging with equipment
  • At least one inspection from city officials

A Week or Longer

Projects may extend past a week when:

  • The property is large or commercial
  • Soil is unstable or groundwater is high
  • Weather delays progress
  • Utilities or tree roots block access

In Louisiana, heavy rain and flooding often extend sewer work beyond the usual timeline.

Factors That Affect How Long Sewer Line Replacement Takes

Length and Depth of the Sewer Line

Longer and deeper pipes take more time to replace. Shallow lines are faster because less excavation is required.

Trenchless vs Traditional Digging

Trenchless methods such as pipe bursting or lining usually save days compared to open trench work. Traditional digging is slower but sometimes necessary when pipes are collapsed.

Permits and City Inspections in Louisiana

Permits are required before starting work. Inspections are scheduled at multiple stages, often at installation and before backfilling. These steps ensure compliance but extend the timeline.

Soil Type and Groundwater Issues

In Louisiana, clay-heavy soil and high water tables complicate excavation. Groundwater pumping may be needed, which adds time.

Accessibility of the Sewer Line

Pipes under driveways, patios, or landscaped yards are harder to reach. Extra labor and restoration extend the replacement time.

Sewer Line Replacement vs Repair – Which Is Faster?

Sewer Line Replacement vs Repair – Which Is Faster?

Sewer repair is usually faster. A small repair takes hours or a single day. Replacement requires days.

Pipe lining or trenchless repairs are often chosen when pipes are structurally sound but leaking. Full replacement is required when pipes are collapsed, deteriorated, or made of outdated materials such as Orangeburg or clay.

Sewer Line Replacement in Louisiana – Local Considerations

Factors That Affect How Long Sewer Line Replacement Takes
  • Permits: Louisiana cities like Baton Rouge and New Orleans require permits before work begins. Approval can take a few days.

  • Soil and Water: High water tables in many Louisiana neighborhoods make excavation more difficult. Clay-heavy soil slows digging.

  • Weather: Heavy rain, hurricanes, and flooding regularly delay sewer projects.

  • Local Codes: Specific material standards and inspection checkpoints are required to pass city codes.

Sewer Solutions is familiar with these local challenges and plans projects accordingly.

Many modern sewer systems, including ATUs, come with alarms that notify you of issues such as low air pressure or system malfunctions. If your alarm goes off:

  1. Do not ignore it. The alarm is designed to alert you to problems that may need professional attention.
  2. Contact a professional: Reach out to a licensed service provider or installer to inspect the system and perform necessary maintenance.

Recognizing the early signs of a failing sewer system can help you avoid costly repairs and health hazards. Look out for these common indicators:

  • Slow drains: If your sinks, showers, or toilets drain slowly, it may indicate a clog or backup in your septic system.
  • Unpleasant odors: Foul smells around the drain field, septic tank, or inside your home could mean there is a problem with the system.
  • Standing water or wet spots: If you notice soggy patches of ground near the septic tank or drain field, this could be a sign of overflow or system failure.
  • Backed-up sewage: A severe backup of sewage inside the house is a major red flag that your septic system is malfunctioning and needs immediate attention.
  • Lush green grass over the drain field: If the grass over your drain field is unusually green and lush, it may indicate an excess of untreated wastewater.

If you notice any of these symptoms, it’s important to call a professional sewer service provider for an inspection and possible repair.

As a sewer system owner, there are a few key responsibilities to ensure your system works properly and lasts longer:

  • Keep the area clear: Avoid placing vehicles, heavy equipment, or structures over your septic tank or ATU. Roots or pests (like fire ants) should be kept away from the system.
  • Monitor the system: Regularly check the system’s operation and make sure the control panel is functioning properly. If your system has an alarm, ensure it’s working and responds to malfunctions.
  • Avoid overloading: Use water efficiently, and avoid flushing non-biodegradable items or harmful chemicals (like bleach or disinfectants).
  • Professional service only: Always have licensed professionals perform inspections and repairs. Unauthorized servicing can cause damage or void your warranty.

The frequency of sewer system pumping depends on the type of system you have and how much water your household uses. Here are some general guidelines:

  • Septic tanks: Pump every 3-7 years, depending on your water usage and the size of your tank.
  • Aerobic Treatment Units (ATUs): These systems typically require less frequent pumping due to their more efficient treatment, but you may still need to pump every 5-10 years or as needed.

 

Regular maintenance checks are crucial. If you notice odors, slow drainage, or unusual discharges, it may be time for an inspection or pump-out.

For your sewer system to function efficiently, it’s important to use only approved products. Here’s a list of safe items for your system:

  • Household cleaners: It’s safe to use household cleaners in moderation, provided they follow the directions on the label. Avoid excessive use, especially with bleach or harsh chemicals.
  • Toilet paper: Only use biodegradable toilet paper designed for septic systems.
  • Laundry detergent: Use sewer-safe detergents in recommended amounts.

 

However, certain products should never go into your sewer system, including:

  1. Large amounts of bleach or disinfectants that kill bacteria
  2. Feminine hygiene products, diapers, and other non-biodegradable items
  3. Cooking oils, grease, coffee grounds, or shrimp shells
  4. Chemical drain cleaners
  5. Plastics, rubber, and large paper products

 

These items can harm the system’s bacteria or cause blockages, reducing efficiency and increasing maintenance needs.

Both Aerobic Treatment Units (ATUs) and septic tanks treat wastewater, but they use different methods:

  • Septic Tank: A septic tank relies on anaerobic bacteria (bacteria that do not require oxygen) to break down waste. The wastewater is held in the tank where solids settle, and liquids are filtered out. Over time, sludge builds up at the bottom of the tank, requiring periodic pumping.
  • Aerobic Treatment Unit (ATU): An ATU uses aerobic bacteria (bacteria that require oxygen) to break down organic waste. Air is pumped into the unit, promoting a more efficient biological process. This method results in cleaner effluent (treated wastewater) and often requires less frequent pumping.

 

Key Differences:

  • Aerobic systems (ATUs) are generally more efficient, producing cleaner treated water and requiring less maintenance.
  • Septic tanks are simpler but can require more frequent pumping and can produce less treated effluent.
