Consider the most significant cost factors for your sewer line installation in Houston, Texas, so you can start budgeting.
Sewer Line Cost per Linear Foot
The average cost to install a sewer line ranges from $50 to $250 per linear foot. Sewer line pipes are about 5 inches in diameter. They run underneath your yard from your house to the main sewer drain, and the average home’s sewer line is 60 linear feet. If you are building a home on a large piece of land in Houston, note that the city code limits sewer lines to 150 feet long or shorter.
| Piping Length (Feet) | Average Cost |
|---|---|
| 30 | $1,250–$6,200 |
| 40 | $1,650–$8,250 |
| 60 | $2,475–$12,375 |
| 80 | $3,300–$16,500 |
Materials
To install a sewer line, you’ll need to purchase the pipes that connect the main sewer drain to your home. New pipes cost about $3 to $20 per linear foot. Factor in the type of piping material to gain a closer estimate as to how much you’ll pay per linear foot by referencing the following chart:
| Type of Piping Material | Average Cost (Per Linear Foot) | Pros | Cons |
|---|---|---|---|
| Cast iron | $2–$10 | Long lifespan, nonflammable | Replaced by newer materials due to corrosion |
| PVC | $0.50–$5 | Affordable, doesn’t corrode | Not suitable for expansive soil |
| ABS | $5–$11 | Resistant to freezing temperatures, lightweight | Sustains UV damage, can be noisy, contains BPA |
| Clay | $50–$60 | Long-lasting, resists acids and corrosive chemicals | Cracks under heavy weight, susceptible to tree roots and soil instability |
| Copper | $20–$30 | Performs in hot climates | Costliest option |

Sewer Line Installation Pro Costs
When hiring a sewer line repair company in Houston, Texas, to complete this labor-intensive project, keep the costs for permits and labor in mind.
Permits and Regulations
Permits are required in Houston for installing a new sewer line. A master plumber applies for the Sanitary Sewer Tap Permit and Road Bore for the Sanitary Sewer Tap Permit, which costs $30. Additionally, they submit the Application for Permit to Construct Main or Lateral Sanitary Sewers for $30. You’ll also need an excavation permit that ranges from $30 to $225.
Labor
Labor accounts for most of the total costs, ranging between $25 and $200 per linear foot. Unlike other projects, this is not a DIYable endeavor, and you’ll need a skilled sewer line pro to take it on.
Does Sewer Line Installation Increase Home Value?
Sewer line installation doesn’t increase your home’s value in Houston because it’s a necessary component of your property. If your home value is lowered due to a sewer line in disrepair, repairing the line or installing a new one is key to passing home inspections and improving your home’s value. Otherwise, you might need to sell your home as-is and lower your asking price.
