LOCKPORT – A Springville company that recently completed an upgrade project at the Lockport sewage treatment plant may begin repairing damage at the plant from the June 28 flood as soon as Wednesday.

Norman D. Allen, director of engineering and public works, said STC Construction will clean out one of the plant’s two grit chambers, which was left clogged after the June 28 flash flood caused the plant to handle 13 times its normal average capacity.

Mayor Michael W. Tucker declared a state of emergency Friday, which Allen said allowed the city to hire STC without competitive bidding. Allen said he chose STC because of its recent work and familiarity with the plant. The city told inspectors from the Federal Emergency Management Agency last week that repairs to the plant would cost about $200,000, but Allen said Monday he expects the tab will be “substantially less.”
