As wastewater from the community enters the treatment plant, it goes through physical separation as well as biological treatment. The treatment process includes separating bio-solids (or sludge) from the water. After the sludge is dewatered, it is hauled offsite. The less water the sludge contains, the better. When sludge is drier, it weighs less and hauling costs are dramatically reduced. Prior to engaging KSA for this project, the City of Tyler’s Westside Wastewater Treatment Plant (WWTP) produced liquid sludge that was hauled from their lagoon by a contractor. The sludge contained only 3-4% solid waste; the rest was water.
