4 multi-media filters (comprised of anthracite, sand, and gravel). These filters are crucial for removing the majority of residual solids in the secondary effluent before disinfection. The pump draws water from the chlorine contact channel to rinse and backwash the media bed of a filter when needed.
As part of the replacement evaluation process, staff examines equipment after 15 years of service, considering hours of use, mechanical condition, continued safe operation, and functionality requirements. When equipment is confirmed to meet the mechanical criteria for replacement, staff also evaluates the continued business need for such equipment.
Staff confirmed that the backwash pump meets the criteria for replacement due to its current age of 15 years and its mechanical condition. Based on the evaluation, the equipment Asset #8250-457 is recommended for replacement.
