ALLOUEZ, WI (WTAQ-WLUK)- The cleanup of a sewage backup on the grounds of the Green Bay Correctional Institution has completed.
The state will spend more than $10,000, after the Village of Allowed pumped more than a half-million gallons of material.
A blockage in the sewer pipe caused a backup to occur earlier this month.
Department of Corrections spokesman Tristian Cooks says it is still unknown how it started.
“We have not been able to definitively determine when the leak began and don’t have a definitive estimate of the amount of material that may have been released,” he said Friday.
One portion of the cleanup, however, was handled by Allouez. Its crews pumped 520,000 gallons of the untreated material back into the sewerage system, according to village administrator Brad Lange.
Between the staff time, pump rental, and replacement of their clothing damaged during the 27 hours of work, the village submitted a bill to the state of $4,834.25, he said.
“As part of our cleanup efforts, standing material was removed from the land, water was pumped from the retention pond into the sewer system, debris and topsoil was excavated for disposal, and a berm was built to prevent additional runoff,” Cook said.
The state paid its contractors $6,800 for the work performed.
