New Sewer Lines Built Right From Start

Complete sewer line installation in Marble Falls for new homes, additions, and full system replacements with proper slope and code compliance.

When you build a new home or add a significant addition in Marble Falls, you need a sewer line that connects your plumbing system to the municipal sewer or septic tank with the correct depth, slope, and materials. Without proper installation, wastewater will not flow reliably, and you risk backups, slow drainage, or code violations that delay occupancy permits. Marble Falls Plumbing LLC installs new sewer lines using code-compliant materials and methods that account for soil conditions, municipal connection points, and long-term performance requirements in Marble Falls.


We coordinate with municipal authorities to confirm connection requirements, obtain necessary permits, and schedule inspections so your installation meets all local codes. The sewer line is installed at the required depth with a consistent slope that allows gravity to move wastewater without assistance. We use durable pipe materials approved for your soil type and connect all fittings securely to prevent leaks or joint separation. The result is reliable wastewater flow that performs correctly from the day you move in.

What Goes Into Installing a Compliant Sewer Line

Installation begins with site evaluation and layout planning that determines the best route from your home to the connection point. We measure elevation changes, mark utility locations, and calculate the slope needed to maintain proper flow. In Marble Falls, we account for rocky soil conditions that may require additional excavation equipment and bedding material to protect the pipe from damage during backfill.


Once the line is installed and tested, your drains will empty quickly and quietly, and you will not experience backups or slow drainage. Proper depth and slope mean the system works reliably without clogs or standing water inside the pipe.


We trench the line to the required depth, lay bedding material for support, and install the sewer pipe with clean, secure connections at every joint. All work is inspected before backfill to confirm compliance with municipal codes. We compact the soil in layers to prevent settling and restore your yard surface. This service covers new installations only and does not include repairs to existing lines or connections to private septic systems unless specified.

Common Concerns About New Sewer Line Work

Homeowners and builders often ask about timelines, permit coordination, and how we handle rocky soil or other site challenges that affect installation.


  • How long does a new sewer line installation take? Most residential installations take two to three days depending on distance, soil conditions, and inspection scheduling. Rocky soil or deep trenches may extend the timeline slightly.
  • What permits are required for sewer line installation? You need a plumbing permit from the local municipality, and the work must pass inspection before backfill. We handle permit applications and schedule inspections as part of the installation process.
  • What type of pipe do you use for new sewer lines? We use schedule 40 PVC or ABS pipe depending on local code requirements and soil conditions. Both materials are durable, resistant to corrosion, and approved for underground wastewater systems.
  • How deep does the sewer line need to be installed? Depth depends on frost line requirements, connection point elevation, and slope calculations. In most cases, residential sewer lines are installed between two and four feet deep to maintain proper flow and protect the pipe.
  • What happens if you encounter rock during excavation? We use rock saws or excavators equipped to break through rocky layers without damaging the trench walls. Bedding material is added to cushion the pipe and prevent damage from sharp edges during backfill.


A properly installed sewer line supports your home for decades without the backups, leaks, or code issues that result from shortcuts or poor planning. Marble Falls Plumbing LLC designs and installs new sewer lines that meet all requirements and perform reliably from day one.
