The inspection of mixers at the Wastewater Treatment Plant in Hannibal was wrapping up on Wednesday.

A crane was being used Wednesday at the Wastewater Treatment Plant in Hannibal.

“We are inspecting and replacing mixers,” said Heath Hall, director of operations for the Board of Public Works.

According to Hall, mixers help disperse the oxygen to the treatment system’s reactor and digester systems.

Only some of the mixers were receiving attention.

“We are inspecting three of the 12 mixers, and replacing some of the existing equipment with new. Some of the existing mixers are original to the plant that was constructed in 1981,” said Hall. “We did some of the inspections in July of 2017, and should finish everything today. The nice weather has helped make the project go well today.”

The project’s cost is around $85,000.
