Preparatory work: Spring/Summer 2019
Dredging and trucking scheduled to begin: September 2019
Estimated completion of dredging, dewatering and hauling work: December 31, 2019
Estimated completion of restoration work: April/May 2020
Why is this project being done?
The City uses lime softening treatment to remove dissolved minerals prior to disinfecting and filtering drinking water. A by-product of this process comes in the form of lime residuals, most of which are captured at the water treatment plant and hauled off-site for use on agricultural land.
However, some lime must be piped to the lime residuals lagoon (located to the west of Wines Elementary School, south of M-14) during maintenance activities or emergencies.
This lime lagoon is nearly full and storage space is needed. The lagoon is regulated by the Michigan Department of Environmental Quality (MDEQ) and the city is responsibility for monitoring and maintaining the lagoon in accordance with permits and regulation issued by the MDEQ.
Work to be done
- Excavate/dredge accumulated material in lime residuals lagoon
- Pump to water treatment plant to be dewatered on-site
- Trucks will haul away dewatered material
- Clean up of roads along hauling route as necessary
Truck Hauling Route
- Residuals will be dewatered at the water treatment plant, located at 919 Sunset Road
- Trucks will haul material away using Sunset, to Newport, to Miller, to Maple.
Possible Impact to residents and/or businesses
- Noise generated the dewatering press equipment at the water treatment plant, dredging/excavation equipment and generator and trucking operations (estimated 2 to 6 trucks per hour).
- Some traffic congestion due to the trucks entering and exiting the site.
