The Backwash basin sludge removal services at the Yadkin River Water Treatment Plant are used to store and settle residuals generated by the water treatment process. As the basins accumulate materials, removal will be required. The basins can accommodate up to 5.5 feet of sludge; however, our goal is to maintain a sludge blanket of less than 4 feet in each basin. To support this, Union County Water is seeking to establish a contract for sludge removal services to be scheduled when sludge blanket depth exceeds operational targets, or upon notification by UCW staff over the next three years. The scope of work shall include the mobilization and demobilization of all equipment and personnel necessary to perform sludge removal, ensuring the safe and efficient removal of sludge deposits from the residual basin. The contractor will be responsible for the proper handling, transportation, and disposal of the removed sludge in full compliance with all applicable environmental regulations including NCDEQ requirements and in strict accordance with all applicable laws. Additionally, the basin must be restored to operational standards and design capacity, free of residual piles, and inspected with UCW staff prior to demobilization following sludge removal. Complete documentation of disposal and any required regulatory compliance paperwork must be provided.
