Firefighters in Bolton, Ont., were called to a blaze at a water pumping station Wednesday morning.

Authorities say the building is located near Mill Street and Highway 50, near King Street East.

Firefighters arrived at the building to find a “well-involved” fire underway after the blaze was called in by a passerby, Caledon Fire officials said.

Footage from a CP24 news chopper showed dark plumes of smoke rising above the building.

No injuries have been reported.

Caledon Fire said the blaze is not expected to impact water distribution as the pumping station is not online.
