Flooded Basements

The primary purpose of sanitary sewer pipelines is to carry sewage from the home to the Metropolitan District Commission sewage treatment facility. When extra water like rainwater is added to the system, a strain on the pipe is created. This strain can often cause water or sewage to back up into the nearest outlet, such as a manhole, a crack in the road, or your basement.

There are several causes of flooding and sewage surcharge:

Rain downspouts that go directly into the ground and into the sewer add excess water to the system. Rain downspouts should be redirected to exit onto the lawn.

Tree roots are another cause of pipe constriction. Older trees have deep roots that, in some cases, have entered into the pipe through the joints, limiting or blocking the flow of sewage and water.

The configuration of the sewer network creates a strain on the passage of water and sewage as well. For instance, pipes are curved at a 90 degree angle before exiting into the main sewer truck, are restrictions and potential sources of blockage.

Lastly, sewage and water may enter a home because mechanical systems, such as a back water valve, are not functioning properly or are not in place.
