Fab Tech LLC employees work on loosening the barrel portion of the city of St. Clair’s clarifier No. 1 on Monday morning at the wastewater treatment plant on Highway AB at Happy Sac Road. The board of aldermen last week approved a recommendation from the administration to spend money to repair and/or replace two clarifiers at the plant, which are part of the process to treat the city’s waste. Clarifier No. 1 has been broken since February.
