Your Guide to Calculating Trenchless Sewer Repair Costs

trenchless sewer repair cost

Cracking and degradation of your trenchless sewer pipe is a clear sign that it’s time for a repair. Unlike traditional pipe repairs, trenchless pipe repairs require a different method to restore the damaged and deteriorated sections of the pipe. This varying method comes with a new set of costs to prepare for. Read on to learn more about the difference between the repairs and how to calculate the cost of trenchless sewer repairs.

Traditional Pipe Repair vs. Trenchless Sewer Repair

Depending on the type of pipe you have, your repair process and cost may vary. Both traditional and trenchless pipe repairs have the same goal—to restore aged and deteriorated piping—but require different methodology. Let’s take a look at the differences in repair and cost.

Traditional Pipe Repair

Traditional pipe repair is commonly a more strenuous process and therefore comes at a higher cost. Conventional pipe repair consists of digging and replacing/repairing the old pipeline. This method is both a significantly more demanding process and can cause disturbances to the general public. Traditional pipe repair pricing begins at roughly $250+ per linear foot with the chance of increased price due to additional factors.

Trenchless Pipe Lining

Trenchless sewer repair is a highly efficient method of restoring aged and deteriorated piping without the digging and disturbances traditional methods require. Since the repairs can occur using a more innovative, less invasive method, the cost of trenchless pipe repairs is typically less. For this type of project, SEKISUI SPR estimates a trenchless sewer repair cost of roughly $30-1,000 per linear foot of pipe replacement. This wide range of cost depends heavily on a few factors, mainly the diameter and length of the pipe.

Factors that Influence Trenchless Sewer Repair Costs

Before starting your project, there are a few additional factors to consider when determining the repair cost. Learn about factors that may influence the overall cost of your trenchless sewer repair below.

Total Length

Trenchless sewer repair costs are heavily influenced by the length of the pipe. For instance, a longer project will most likely contain lower material costs per linear foot than a shorter project of similar diameter due to scale. Renewing 100 feet of pipe compared to 1,000 feet will yield different dollar amounts within the line items of a project bid. This cost may go up depending on other factors, such as the size, shape, and material of your pipe.

Pipe Size & Shape

The size and shape of your pipe are a major factor in the overall cost. Larger diameter pipelines will typically cost more per linear foot to repair than a smaller pipe. For example, longer runs of pipe under 15” routinely cost below $100 per linear foot for trenchless rehabilitation. The shape of the pipe may also influence the cost of the trenchless sewer repair. With more untraditional piping shapes, it may require additional work to repair the pipe to fit the initial shape. When planning a repair, knowing the size, shape, and type of pipe you’re dealing with can make the project run a little smoother.

Repair Technique

Though trenchless sewer repairs are commonly more cost-effective and simpler than traditional pipe repairs, they can sometimes require additional items that add to the overall cost. Some trenchless sewers may need bypass pumping for the repair process, adding further costs. Bypass pumping is beneficial for pipes with too much existing flow for a trenchless repair method to handle or when a technology calls for a dry pipe. This supplementary process will increase the trenchless sewer repair cost.
