NIGP 89005: Belt Filter Press and Parts

NIGP 89005 Belt Filter Press and Parts is an Item code covering the procurement and maintenance of belt filter press equipment and components used by municipal water and wastewater treatment facilities. State and local governments buy under this code replacement belt filter presses with complete dewatering and solids-capture systems; proprietary parts and authorized maintenance services from original equipment manufacturers; and ancillary equipment including polymer blending systems, metering pumps, process control and SCADA integration, electrical modifications, and piping work. Municipal water departments, wastewater treatment facilities, and county water resources departments are the primary issuing bodies. Procurement scopes range from full system replacements with installation, startup, operator training, and comprehensive warranties to ongoing parts and maintenance contracts serving multiple treatment facilities across a jurisdiction. Recent solicitations reflect equipment-specific needs: the City of Valdosta's bid for a replacement belt filter press at its Withlacoochee Water Pollution Control Plant specified performance benchmarks including 15 percent minimum cake dry solids and 95 percent minimum solids capture, with factory testing and five-day acceptance testing protocols; the City of Fairburn's RFP for retention pond cleaning and sediment removal included dewatering services among its scope, placing ancillary dewatering equipment within the procurement context.

Recent activity concentrates in Georgia, with the City of Valdosta (Lee County) posting Bid #36-26 on February 10, 2026, for sealed bids due March 24, 2026, and the City of Fairburn (Fulton County) posting RFP 26-008 on May 5, 2026, with proposals due June 4, 2026. Hillsborough County, Florida's Water Resources Department conducted a sole source procurement with DXP Enterprises, Inc., for proprietary equipment, parts, and maintenance services totaling $6,600,000 over five years across multiple water, reclaimed, and wastewater treatment facilities, posted January 30, 2026. Equipment replacement contracts typically include mandatory pre-bid site visits, sealed bid or RFP processes, performance bonds, insurance requirements including pollution liability, and compliance with federal wage and environmental regulations. Ongoing parts and maintenance arrangements are often structured as five-year contracts with tiered labor rates by discipline and time classification, encompassing factory-trained technicians, design and engineering support, and integration with existing proprietary systems.
