Flooding History

Sewage back up – Basement drains backing up – Sewer backup and flooding  

  • Each year in the United States, backed up sewers back causing floods in basements occur nearly 500,000 times when about 50,000 municipal sanitary sewers overflows occur. This sewage back up situation creates an environment in which potentially deadly pathogens are introduced into the home and conditions are created in which toxic black mold can grow in the basement.The biggest problems arise in systems that combine storm water and raw sewage into the same pipeline. During many rain storms, the systems are exposed to more volume than they can handle, and the result is a sewage back up situation that allows sewage to spew out, flooding into basements and other low lying drains. The desire to broaden local tax bases by building more and more homes connected to already aging sewage systems has also contributed to rapid increases in sanitary sewer back ups, flooded basements and overflows. 
  • The reality that funding to maintain and improve sewer systems has decreased while the demands placed upon these aging sewer systems has increased makes the flooding problem even worse. Sewage backups endanger the health of hundreds of thousands of Americans and create hefty repair bills for cities and consumers alike (as we personally found out). While local officials and voters have been treating sewers as an “out of sight, out of mind” problem, the results of backed up sewers are increasingly making themselves known in basements throughout the nation.
  • The Civil Engineering Research Foundation reports that backed up sewers are increasing at the alarming rate of about three percent each year. A recent report from the American Society of Civil Engineers indicates that the nation’s 500,000-plus miles of sewer lines are on average over thirty years old. Our nations aging sewer systems are overflowing and flooding basements with increasing regularity and introducing unprecedented amounts of pollutants into our homes and buildings. 
  • Studies indicate that over one million Americans become ill each year just from backed up sewer incidents. Raw sewage contains powerful bacteria like E coli, viruses, intestinal worms and parasites. Most of those affected suffer stomach cramps and diarrhea, but untreated sewage can also spread horrible diseases such as cholera and hepatitis. Gastroenteritis and cryptosporidiosis are other parasites contained in sewage and can kill humans when high concentrations are encountered.
  • The Water Infrastructure Network, a group of water and public-works associations, believes that municipal governments / ratepayers will have to provide up to $12 billion a year for capital improvements in the next two decades to replace aging sewer pipes and to meet EPA guidelines. Estimates in some regions show sanitary sewer replacement costs could reach up to $15,000 PER HOUSEHOLD. Due to the high costs involved, this upgrade won’t happen quickly. 
  • In the meantime, those connected to sewers prone to back ups are forced to fund repairs out of their own pockets. And many recommended repairs costing thousands of dollars end up not working. Many homeowners are advised to replace the pipe leading from their dwelling to the street at a cost of about $75 per foot (an average 50′ line is nearly $4,000). But when the problem is that the sewer line at the street is backing up, the newly replaced line will allow a sewage backup backup just as easily as the old sewer line. In some sewer back up situations, so much pressure occurs that solid steel manhole covers are popped several feet into the air above a raging fountain of raw sewage. If any drain in your home is located at a point lower that that manhole, the same raw sewage fountain will occur in your home.
