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 is a Commodity code that covers the equipment, mobilization, and labor for testing and developing production water wells after drilling — specifically the temporary pumping apparatus, instrumentation, and staged testing protocols used to measure well performance and aquifer response. State and local governments procure this work primarily through municipal water authorities and special districts developing new drinking water sources. The scope spans furnishing and installing test pumps with specified flow capacity, conducting step-drawdown and constant-rate pump tests over defined durations, measuring static and dynamic water levels and sand production, performing swabbing and well development to maximize efficiency, and executing comprehensive water quality laboratory analysis. Contracts are typically structured as unit-price or fixed-price bids with tight completion windows (90–120 days from notice to proceed) and prevailing wage requirements when contract value exceeds threshold amounts.

Recent activity shows geographic spread across the Mountain West and Mid-Atlantic regions. The City of Orem, Utah issued two complementary solicitations in October 2026 — IFBs for both the drilling (reverse-rotary method to 800 feet) and the subsequent development and pump testing of Well #1R, with response deadline October 22, 2026 and a mandatory pre-bid conference scheduled for October 8, 2026; evaluation criteria weighted qualifications and experience at 60 percent, cost at 15 percent, and scheduling at 25 percent, with liquidated damages of $200 per day assessed for delays. The Maryland Environmental Service issued a competitive sealed bid IFB in May 2026 for drilling, construction, and testing of a potable water production well at Camp Fretterd Military Reservation in Baltimore County, with a June 12, 2026 response deadline, a mandatory pre-bid conference on May 22, 2026, a 5 percent MBE subcontract participation goal, and liquidated damages of $1,264.00 per day; award was based on lowest responsive bid price from a responsible bidder with Maryland contractor licensure and documented financial and construction experience required.
