Description Replace the Grit Classifiers located in the Grit Building including any required piping and bunker modifications. Project includes installing a bagging system and roll-off to move away from having to install a liming system to meet IDNR grit disposal requirements. This cost includes the 2 roll-off containers. Justification The grit classifiers were installed in 2002 and have requiried a major frame repair in 2015 and multiple rotating parts replacment over the past 5 years. The equipment is at the end of it's useful design life. IDNR rules require raising the grit pH to 12 for 2 hours, by installing a bagging system and roll-off, we can apply for a waiver for liming and the roll-off will reduce staff handling the grit. With improvements in technology, the new classifiers are more effective at dewatering and will produce a drier grit. Total Pr oject Cost: $394,000 Status Active

Budget Impact/Other Grit removal is critical in WWTP operations in meeting its NPDES permit and reduces wear and tear on down steam pumping. Scheduled replacement is is more cost ffective than an emergency replacement project. This project repairs existing equipment which should reduce maintenance and repairs costs. The estimated impact on the operating budget is less than $10,000.
