UNSPSC 41114300: Hydrological instruments

UNSPSC 41114300 Hydrological instruments is a Class code encompassing the sensors, controllers, interface boards, monitoring equipment, and field measurement services that state and local water and environmental agencies deploy to measure water systems, detect hazardous conditions, and manage SCADA infrastructure. State and local governments procure atmospheric monitoring instruments to detect hydrogen sulfide, methane, chlorine, and other gases at water treatment and wastewater facilities; controllers and interface boards for lift stations and pump monitoring; advanced HMI displays for system control; and field hydrogeological measurement and analysis services supporting groundwater investigation, permitting, well design, and water quality monitoring. The issuing bodies include municipal water departments and utilities (City of Tampa, City of Phoenix Water Services), regional water supply authorities (Tampa Bay Water), city water systems (City of Gallup), water management districts (Suwannee River Water Management District), and waste-energy authorities (Solid Waste Authority of Palm Beach County). These agencies source equipment and services for installation at lift stations, headworks buildings, chemical storage rooms, confined space entry points, pump stations, tank sites, well sites, and flow control stations across multiple locations.

Recent activity spans Florida, Arizona, and New Mexico, with concentrated purchasing by Tampa and Phoenix. The City of Tampa issued two RFQs in October 2026 — one for controllers and phase monitors (27P00018, due October 29, 2026) and one for Advanced HMI 15-inch displays (26P00515, past due as of today) — both requiring five-business-day delivery and firm pricing. The City of Phoenix Water Services Department solicited sealed offers for atmospheric monitoring instruments including sensors, controllers, alarms, and calibration materials under IFB 27-0435 (due September 4, 2026), with a five-year contract term, DBE-N compliance, and 48-hour replacement-parts availability required. The City of Gallup, New Mexico issued an RFP for a comprehensive SCADA system upgrade serving 46 water distribution locations (due December 18, 2025, now closed) under a five-year indefinite quantity contract with New Mexico resident business preferences. Tampa Bay Water selected five firms for as-needed hydrogeological services task orders under RFP 2027001015 (due June 30, 2026), with awards anticipated October 19, 2026, covering permitting assistance, groundwater and surface water modeling, well design and inspection, and water quality monitoring across a five-year term. The Suwannee River Water Management District solicited field support services for agricultural water use monitoring across fifteen Florida counties under ITB 16243 (due July 1, 2026), requiring flow measurements, data entry, and administrative documentation with MBE and VBE preferences.
