Wastewater Solids Management
Description
For $77,500.00 in additional payment authority for Contract 143579 with Wastewater Solids Management for digester tank cleaning services for the Water Services Department. The digester tanks are used for sludge digestion which is the biological degradation or stabilization of organic matter. To maintain the performance of the digestion process, digester tanks are required to be cleaned on an as-needed basis. Additional payment authority is needed due to an increase in demand for digester tank cleaning and an underestimation of the funds needed for the option years.
