UNSPSC 20122221: Well test units

A well test unit is simply a period of time during which the production of the well is measured, either at the well head with portable well test equipment, or in a production skid mounted facility.

UNSPSC 20122221 Well test units (Commodity) encompasses the drilling, construction, development, and comprehensive testing of production and potable water wells for state and local water utilities. State and local governments procure under this code the complete package of well-drilling services including bore-hole excavation, casing installation, well development, and the specialized testing required to characterize well performance—step-drawdown testing, constant-rate pumping tests, recovery testing, and water quality laboratory analysis. Work also includes temporary equipment supply (pumps, generators, associated accessories), utility coordination, sediment and erosion control, and final documentation and restoration. Issuing bodies include state environmental agencies, county utilities, and special-purpose water authorities; Maryland Environmental Service and Collier County have both recently solicited under this code.

Recent activity spans Maryland and Florida. The Maryland Environmental Service issued an IFB in May 2026 (Solicitation 1262565, response due June 12, 2026) for drilling and testing a 10-inch potable water production well to 300 feet at Camp Fretterd Military Reservation in Baltimore County, with 120-day performance deadline, MBE 5% subcontract participation goal, prevailing wage applicability above $250,000 base bid, and $1,264 per-day liquidated damages. Collier County, Florida posted Bid No. 25-8418 in August 2025 for improvements to two existing wells including pump, motor, piping, electrical, instrumentation, and well conditioning, budgeted at $2,900,000 plus $200,000 owner's allowance, with October 8, 2025 sealed-bid deadline and non-mandatory September pre-bid meeting, 365-day substantial completion window, and $1,201 per-day liquidated damages. Both opportunities require bid bonds, performance and payment bonds, proof of insurance, and contractor licensing and debarment certifications.
