From The Colorado Springs Gazette (Ryan Maye Handy):
…some incorrectly installed sump pumps in the Pleasant Valley neighborhood, around Colorado Avenue and 31 Street, have caused Colorado Springs Utilities’ wastewater lines to overflow with groundwater.
Utilities crews have worked for the last two weeks to remove some water from overloaded wastewater systems before the contaminated water overflows manholes and rushes into the street, said Utilities spokesman Steve Berry.
Pumps hooked up directly to the wastewater system are a problem for Utilities and homeowners.
“The number one risk is really for the customer,” Berry said Tuesday. “If the sump pump is hooked up to the wastewater system … then the biggest threat is really to your home.”
If excess groundwater gets pushed into the wastewater system, it could backfire and send water back into a home or a neighboring home, Berry said…
Sump pumps are supposed to discharge excess groundwater outside a home, typically through a pipe that dumps into a yard. But, particularly in older neighborhoods such as Pleasant Valley, sometimes the pumps are connected directly to a home’s wastewater line, which connects to Utilities’ wastewater main.
Homeowners own their wastewater lines and are responsible for maintaining them, and if damage on the private line affects the main Utilities line, homeowners could be liable, Berry said. He said homeowners should make sure pumps are correctly installed, although most will likely have to hire someone to check the system.
“These folks don’t even know, and it’s certainly not their fault, but now they need to,” Berry said.
