NIGP 82032: Chemical Feed Systems (for Proportioning Pumps See Class 720)

NIGP 82032 Chemical Feed Systems (Item code) covers proprietary chemical dosing equipment, replacement parts, and OEM service support for water treatment and wastewater operations. State and local governments purchase lime slaking systems, polymer blending units, sodium hypochlorite storage tanks with automated monitoring, and related chemical feed infrastructure to manage treatment processes at public water and wastewater facilities. Buying patterns center on OEM parts, manufacturer-authorized maintenance and service contracts, and integrated chemical storage and distribution systems designed for specific facility configurations. Issuing bodies include city public works departments, county utilities, and municipal wastewater authorities. Recent solicitations emphasize sole-source procurements tied to proprietary equipment already installed, as well as competitive bids for equipment replacement and facility upgrades at treatment plants.

The City of Holly Hill, Florida issued two sole-source notices in October 2026 for lime slaking systems from Chemco Systems LP and separation equipment parts from Andritz Separation, Inc., citing the specialized, non-interchangeable design of existing infrastructure. The City of Santa Fe released an ITB in September 2026 for chemical feed, VFD, and SCADA replacements at the Paseo Real Wastewater Reclamation Facility, with bids due October 8, 2026 and an estimated project cost of $3.7 million, including installation of double-walled fiberglass chemical storage tanks. The City of Atlanta's Department of Watershed Management posted an IFB in May 2026 for polymer blending units, OEM parts, and repair services for SNF Polydyne Floquip equipment across multiple treatment facilities, with a pre-solicitation conference scheduled. Lowndes County, Georgia solicited permanent bypass pump installation at 20 lift stations in July 2026, bids due September 1, 2026. Recent activity concentrates in Florida, Georgia, New Mexico, and municipal/county utilities in the Southeast; solicitations reflect a mix of sole-source OEM maintenance contracts and competitive procurement for facility upgrades subject to prevailing wage and equipment-compatibility requirements.
