Sewer Pipe Lining

Cities with outdated sewer systems – those that warrant an entire system update – can be faced with repair costs totaling hundreds of millions of dollars (if not more).

Unfortunately for cities in these circumstances, intervention isn’t an option — it’s a requirement — otherwise, further sewer damage and expensive upkeep are sure to follow. With traditional trenching methods, replacing an entire municipal sewer system on the verge of collapse could cost upwards of $2 billion. This is partially because many sewer lines run beneath sidewalks, streets and buildings, so excavating a damaged line can be extremely costly, and sometimes even impossible.

Enter trenchless pipe lining — a solution allowing cities to restore sewer pipe lines that cannot be affordably dug out and manually replaced.

In contrast to the $2 billion price tag for a total replacement, a typical municipal sewer lining project will cost a few thousand dollars per line, and generally a few hundred thousand dollars in total. For example, a Sacramento sewer lining project we completed in 2014 cost roughly $600,000 total. While this is of course no small cost, in comparison to the alternative, these types of lining projects are much more affordable. The technologies used in lining cost more upfront than those used in trenching, but the landscaping, down-time and labor associated with traditional replacement are entirely avoided, resulting in a lower overall cost.

The standard sewer pipe lining technique, known as manhole-to-manhole lining, works very much like it sounds. Using existing manhole entry points, trenchless lining experts can reline damaged sewer lines from within — and no digging means no landscaping damage or restoration costs. With manhole-to-manhole sewer lining, large-scale projects that would otherwise cost a city millions of dollars can be done for thousands.

The lining of a single sewer line is typically completed in a single day, over the course of several hours as the epoxy resin liner materials cure in-place (hence the industry term, “cured-in-place pipe,” or CIPP). This significantly cuts overall project time and costs, and helps municipal decision-makers avoid the disruptions of road closures entirely.

Unless the damaged lines in question are collapsed, trenchless lining can restore pipes affected by almost any kind of damage. This includes common problems like leaking joints, intrusion and cracked pipe, as well as more severe issues, such as clogging caused by health products, “flushable” wipes, and paper products.

Generally, the biggest cost and time savings of trenchless manhole-to-manhole lining isn’t in the technology itself, but in the process complications it helps municipalities avoid; complications common in dig-and-replace sewer renovations. Once lined, new sewer walls will retain their structural integrity for well over 50 years of standard use. Cured-in-place sewer lines perform just as well as concrete sewer lines, and in many cases are much more durable.
