A piece of equipment purchased last year by the Knox Wastewater Department has already paid for itself. The city spent $12,500 on a biosolids injector. Wastewater Superintendent Kelly Clemons says it’s used to apply biosolids produced by the plant into farm ground to provide a natural source of nutrients for area farmers.
She told the Knox Board of Works recently they’ve already done two applications and realized a savings of nearly $30,000 over having a vendor come in to remove sludge.
