Sewer Line Installation Cost Factors
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 |
Demolition and Prep
Trenching: $800 per 100 linear feet
Boulder removal cost: $650–$1,200 per boulder
Tree removal cost: $200–$2,000 per tree
Pavement removal cost: $8–$15 per square foot
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.

Coopers came recommended. We needed a new Water Heater and they did the install for us. We also used them again today, to repair a leaking toilet. We have finally found a plumbing company we can trust. Their response times are prompt and their technicians are courteous and professional.

OK, I wished he would have replaced the inside of toilet. Instead he told me I was flushing wrong. ie. holding the handle down to long which prevented the tank from filling up properly with water. Hard to change the way you flush. This company is good and I had previous experiences with them...

Show Plumbing - Mark W.

America's Best Electric Co - David M.
Contact them regarding replacing hot water heater. I noticed water in the drip pan and the unit is 9 years old. They came out the same day for a free estimate. Provided pros-cons on tank versus tank-less with no sales pressure to go either way. Agreed on the work for a 50g tank unit and...
