The average household has many sources of sewer water. This water may come from the use of sinks, showers, and bathrooms. Water from these sources go down into the sewer pipes of your home into the ground.
To many, what lies under the foundation of the average home is a mystery. One of the challenges with living in an historic city is the amount of underground obstructions. Examples may be cobblestone left over from a bygone era when Richmonders and visitors traveled by horse and buggy, trash and debris, abandoned utility lines, rail remnants from Richmond's streetcar era, even old Civil War artifacts.
Modern water lines and other utilities such as cable television, telephone, and natural gas can also serve as blockages.
Root systems are underground obstructions that can cause infrastructure damage to sewer and storm drain lines.
