You might have gone to town or walked outside your home and noticed an unsavory smell. You are affronted with a plume of sulfuric fumes somewhere in your vicinity. Why is there an outside sewage smell? It is clearly the nearby sewer system. Why here and why now? Many ask these questions, and below, you shall find the answer.
What Is Sewer Gas?
The nasty odor you smell is sewer gas, a combination of gaseous chemicals that emerge when organic material breaks down. The organic material could be your average waste, but it could also be debris that does not belong in a sewer, whether for stormwater or wastewater. The concoction is hydrogen sulfide, a combination of methane, carbon dioxide, ammonia, nitrogen, and more. Together, they create the rotten egg smell.
Why Is There an Outside Sewage Smell?
Blockages could form rapidly or over a long time. Any buildup of organic materials could produce more odors, especially if other factors are at play. The gas will then seep through the catch basins of combined sewer systems and manhole covers up to the street above and into the surrounding area.
Lengthy Travel of Materials
The longer the material remains in its original state without processing, the smellier it will get as it breaks down over time. That is why blockages will produce a stronger smell, as well as products that travel many miles to pass through certain areas prone to sewer smells.
Many sewer systems rely on gravity to carry wastewater down to the treatment plant; they are designed to carry a general amount of water at a certain velocity. When more water than usual flows through the system, one can expect turbulence. Some parts of the system naturally have more turbulence than others, also. With this phenomenon comes stronger smells.
Higher temperatures create more smells. If the sewage pipes are close enough to the surface or part of a combination sewer system, you are more likely to get a whiff of that nasty gas on a hot summer day.
How to Treat That Outdoor Sewage Smell
Sewer system workers treat particularly smelly areas with a deodorizing chemical treatment at strategic times. Meanwhile, periodic sewer pipe cleaning keeps blockages at bay. Jet Blast Inc. is happy to help keep your municipality’s streets odor-free with water blasting and vacuuming services!
