What Causes A Sewer Backup
What Causes a Sewer Backup?
Each spring in Michigan brings with it additional rain and frequent storms that create the season of sewer backups. Once a flooded basement is discovered it is common to ask , “what causes a sewer backup” and make sure steps are taken so it never happens again.
Several of the cities in Southeast Michigan that are known for sewer backups are Berkly, Birmingham, Royal Oak, Madison Heights, Roseville, Warren, Eastpointe, Grosse Point, Saint Clair Shores, and Huntington Woods.
While any city in Metro Detroit can have a sewer backup, these cities experience more frequent sewer backups. Why? You may ask. Because these cities have many homes that were built before the 60s and the materials that the drain systems were made from are beginning to deteriorate. Many homeowners have had the unfortunate experience of having to replace their old sewer systems with more efficient modern materials. The cost can be rather staggering, especially because often they discovered they had a problem after a serious sewer backup. The water from a sewer backup is so contaminated that whatever materials it touches must be either discarded or disinfected to kill germs and restored.
What Causes a Sewer Backup
Old drain systems are deteriorating from aging
Years buried in the ground these old clay systems are cracking, breaking, deteriorating and being clogged by growing tree roots. The drains gradually become so clogged that the sewer and storm water they channel from the home, begins to move slower and slower. One day especially after a storm or thawing snow, they fail and sewers backup. It is estimated that over half the nation's sewer systems are older than 30 years old. Old drain systems are what causes a sewer backup in the majority of flooding in Michigan basements.
Dual pipeline system
Many of the homes located in the cities previously mentioned have dual pipeline systems that combine both ground water from rain with the sewer water from your toilets and drains. Although each system is distinct from the other they both get carried away from the home by the same last stage drain pipe. What causes a sewer backup is that these old drain pipes have the entire burden placed upon it to keep the basement from flooding during raining. Often the system is half blocked and intense volumes of water from heavy rain showers place the home in jeopardy for a sewer backup.
Tree Root Invasion
Roots in the ground from trees and shrubs require moisture to survive and are drawn to sewer drains buried in the ground. Once they grow close enough they will gradually begin to invade its pores and tiny cracks like a bee stinger to skin. Eventually with a bit of time it prevails and gets what it came for; water. Tree roots are what causes a sewer backup in the majority of sewer backups and a bit of preventative maintenance can help prevent one.
