UNSPSC 47101535: Sludge disposal equipment

UNSPSC 47101535 Sludge disposal equipment is a Commodity code under which state and local governments procure wastewater treatment plant infrastructure rehabilitation, equipment replacement, and related hauling services. The recent solicitations show two distinct categories of work: rehabilitation and replacement of critical anaerobic digester tanks and associated treatment systems, including aeration equipment, decanters, piping, and control systems; and raw wastewater transportation services. Issuing bodies include municipal water and wastewater utilities, county-level water authorities, and state environmental service agencies operating treatment facilities. The City of Goodyear, Arizona, appears as a repeat buyer, having issued two solicitations for the same Corgett Water Reclamation Facility digester rehabilitation project (IFB 26-0142 posted April 21, 2026, and earlier IFB 260073 posted January 22, 2026). Equipment procurements typically require Arizona Registrar of Contractors licensing or equivalent state credentials, comprehensive bonding (10 percent bid bond, 100 percent performance and payment bonds), and substantial insurance coverage including general liability up to $2,000,000 aggregate and professional liability where applicable. Work scopes emphasize asset-life extension, operational reliability improvements, and regulatory compliance with federal EPA, state environmental, and local building codes.

Activity concentrates in Arizona and Maryland, with recent opportunities spanning the City of Goodyear, Arizona; the City of Holly Hill, Florida; and the Maryland Environmental Service (Stevenson University Wastewater Treatment Plant, Baltimore County). The Goodyear digester tank rehabilitation (IFB 26-0142, due May 15, 2026) seeks replacement or rehabilitation of a 20,000-gallon anaerobic digester including aeration systems, decanters, piping, and vent systems, with a 300-day completion timeline and lump-sum pricing across nine distinct work items; questions must be submitted by May 1, 2026, to Jacque Behrens at jacque.behrens@goodyearaz.gov, and bids are submitted through the City's Bonfire procurement portal. The Maryland Environmental Service issued an IFB for raw sewage hauling at Stevenson University (due February 23, 2026) on a 24-hour on-call basis for approximately 3,200,000 gallons per year at per-gallon unit pricing, with the incumbent contractor (Colson's Septic Service) operating at 8 cents per gallon, and site visits available by contacting Dave Coale at dcoale@menv.com. The Holly Hill, Florida, procurement (posted April 13, 2026, adoption date September 22, 2020) was a sole-source purchase of a WesTech DS43 dual-shaft drive unit at $113,067.00 total ($79,159.00 equipment, $33,908.00 installation) through authorized representative Moss-Kelley, Inc., requiring no competitive bidding due to equipment exclusivity.
