BG to use bugs to cut phosphorus

Bowling Green is going to enlist the help of bugs to treat its wastewater.

Brian O’Connell, director of public utilities, told city council Monday evening that the city would be paying $126,000 for a biological phosphorus removal project. The project will involve making changes to the aeration and “tricking” microscopic bugs already in to wastewater to eat the phosphorus before it leaves the plant.

Phosphorus is one of the culprits blamed for the algal bloom crisis in Lake Erie in the summer of 2014. Phosphorus got to the lake from sources such as sewer plants, farm fields and lawn chemicals. According to O’Connell, by using a biological rather than chemical treatment, the water downstream will benefit.

“We’re going to use the bugs in our wastewater plant to consume the phosphorus,” he said.

The change is not being required by the Ohio EPA, but O’Connell said environmental regulations are all pointing in that direction.

“We are trying to be proactive,” he said.

O’Connell said after the meeting that the change should cut the phosphorus that leaves the plant in half.

Also at Monday’s meeting, council approved plans for working with the Ohio Department of Transportation for resurfacing the city’s portion of Ohio 105 from Bowling Green’s east side to Ohio 199.

During the citizen comments portion of the meeting, Diane Vogtsberger asked council questions about its plans to hire a consultant to do a site assessment of the green space on West Wooster Street which was formerly the site of the junior high school.

Council President Mike Aspacher answered her questions, saying Poggemeyer Design Group would be paid $3,200 for the site assessment, creating three artistic renderings of possible uses. There is no timeline for the assessment, he said. The decision to hire the consultant was made by Aspacher, Mayor Dick Edwards and City Administrator Lori Tretter following a public meeting about the proposed use of the green space.
