Some people in Kingston, Ont., were asked to conserve water after a pipe broke Thursday at the River Street Pumping Station, flooding it with sewage. It's expected to be back to normal Friday morning. Utilities Kingston said residents should also take steps to protect their basements from flooding. "We are appealing to the public to conserve water and reduce sewer use to help reduce overflows and protect the environment," said president and CEO of Utilities Kingston president and CEO Jim Keech. Keech said Thursday afternoon they still didn't know what caused the pipe to break.
