LEMONT – Construction at the Lemont Water Reclamation Plant at 13 Stephen St. will require the use of explosives on the bedrock that could be heard and felt by Lemont residents.
Adam Johnson, a public information officer with the construction company J.J. Henderson, said the blasting is expected to start around the end of December and to take place during the course of a couple of weeks, though weather could affect the schedule.
A preblast siren, which should be heard in downtown Lemont, will sound before each blast, he said.
Johnson said construction workers are allowed by contract to work from 7 a.m. to 3:30 p.m. Monday to Friday, but said the workers will try not to blast anything too early.
As the blasts go deeper into the bedrock, the sound should lessen, he said.
Johnson said that If residents hear the blasts and are concerned, they can contact him at 847-244-3222 or firstname.lastname@example.org.
According to a Metropolitan Water Reclamation District spokesperson, the construction is for a Wet Weather Treatment Facility, which will store excess water during storms until it can be treated.
The spokesperson said water from the combined sewer system can exceed the plant’s treatment capacity of 4.5 million gallons per day during storms.
Construction on the reservoir began in October and is scheduled to be completed by mid-2015.
