| If you've ever seen something like this, you've seen the result of something called
Inflow & Infiltration! I/I, as it's not-so-affectionately called by
professionals, is the process of stormwater runoff getting into the sanitary sewer
system. A sewer system is designed to transport wastewater to a treatment facility,
and in dry weather does so without the kind of overflow depicted in these photos.
However, in wet weather, storm-related runoff may leak into the sewer system, resulting in
a volume of flow the system wasn't designed to handle!
|
| Not only do cracks, leaks, and defects in the sanitary sewer line allow I/I, but
blockages within the pipes can hamper the flow. These blockages might be roots,
offset pipe joints, and even collapsed pipe. Although scenes such as those pictured above are indicative of a problem within the sewer pipe, locating that problem can be challenging. This is where smoke tests come in! |
