NIGP 93691: Water Supply and Sewage Treatment Equipment Maintenance and Repair

NIGP 93691 Water Supply and Sewage Treatment Equipment Maintenance and Repair, an Item code, encompasses state and local procurement of spare parts, replacement equipment, and field service work for water treatment plants, wastewater reclamation facilities, and pumping stations. Recent solicitations show state and local governments buying reverse osmosis system maintenance agreements, valve actuators for treatment plants, grinder and digester component replacements, turbine pump motors, electromagnetic flow meter transmitters, control panel fabrication and refurbishment, water tank cleaning and inspection, backflow device testing, and specialized equipment parts (UV disinfection systems, blowers, chlorine analyzers, water meters). A mix of issuing bodies drives activity under this code: county water authorities, municipal water departments, regional wastewater utilities, and special districts. Water authorities and cities appear as repeat buyers—Macon Water Authority, City of St. Petersburg, City of Phoenix, Seminole County, Gwinnett County, and Marion County Utilities each solicited multiple times in recent months.

Recent opportunities span Texas, Georgia, Florida, and Arizona, with concentrated activity in Florida and Georgia. Representative solicitations include Texas A&M University's ITB for annual reverse osmosis maintenance (bids due October 21, 2026), Gwinnett County's sealed bids for Beaver Ruin Diversion Pump Station grinder replacement and installation (bids due November 20, 2026), Macon Water Authority's ITB for two 1000 HP vertical turbine motor installation (bids due November 17, 2026), City of St. Petersburg's sole-source procurements for Flowserve Limitorque valve actuators at the North East Water Reclamation Facility, and Seminole County's IFB for valve and flow meter installation on a force main (engineer's estimate $913,000). Specialized equipment maintenance and repair contracts dominate the mix—on-call cooling tower water treatment (City of Phoenix), sewer camera maintenance (City of Dallas, 36-month ID/IQ), tank cleaning and inspection (Long Beach), and fabrication of FEMA-compliant control panels (Broward County). Many jurisdictions require vendor experience with specific equipment lines (Siemens SITRANS flow meters, Trojan UV systems, JWC Environmental grinders, Howden Turblex blowers) and manufacturer certifications or authorized distributor status. Mandatory pre-bid meetings and site visits are standard; response dates cluster in October–November 2026 and early 2027.
