(KMOV.com) -- Shifting grounds and broken sewer line connections could be costly for some Alton homeowners.
Alton Public Works Department said part of State Street collapsed after a broken water line washed away ground under the pavement.
When Alton officials ran a camera down the sewer main, it saw connections from three of the homes into the main sewer line were deteriorating.
Officials said homeowners are responsible for the sewer line from their homes to the main.
Public Works Director Robert Barnhart said it is a problem of an aging infrastructure facing neighborhoods across the area.
“Things shift, the ground shifts. These are old systems,” said Barnhart, “They’ve been here 100 plus years. They were installed with technology that was best they had at the time. Things are different now.”
Barnhart said it will likely become more common.
The cost to repair the connection can be anywhere from $1000 to $10,000.
