Limestone residual is generated at the Water Treatment Plant as a result of the water softening process. The limestone residual has been designated an agricultural liming material by the Michigan Department of Agriculture and can be recycled by applying it to farmland. Additionally, it has been approved as a soil ad-mixture to fill gravel pits.
A complete pressing and discharge of residual from one of the filter presses the Water Treatment Plant is termed a "dump". A dump is approximately seven (7) cubic yards and weighs eight (8) tons. The plant produces approximately 2,200 dumps per year. At $148.00 per dump the estimated first year contract would be $325,600.00. After the first year, the contract provides for annual adjustments to the unit price based upon 80% pf the Consumers Price Index. The estimated three year cost is $976,800.00.
