The grit system is removing 99 percent of incoming grit, even during wet weather surge events. |
That’s significant because of the heavy flows encountered during wet weather.
“We are a combined sewer system so during storm events flows can actually reach 13.5 MGD,” Petrovich said, adding that the new 12 MGD grit chamber “wasn’t missing a beat. It pulls out all of the grit.”
The performance of the system is especially impressive, according to Petrovich, when you consider that it requires significantly less O&M than the previous unit. The recommended maintenance schedule consists primarily of periodic lubrication, he said.
“There has been very little trial and pain,” Petrovich remarked. “After start-up, we had to adjust certain settings, but since then we have had basically no other maintenance.”
