An investigation is underway into an accident at the Sewickley Waste Water Treatment plant where one worker was killed and three others injured.
According to Sewickley Fire Chief Jeff Neff, the first call to the county 9-1-1 system said four men were trapped in a shaft at a construction site at the plant. It appears that one man was working in a shaft and either fell or was becoming light-headed from fumes and radioed for help. Three other workers came to his aid in the shaft and they were overcome by fumes. 2 of the surviving workers are in good condition at Allegheny General Hospital, another is in fair condition.
