NIGP 94169: Pipeline Pressure Flushing Services

NIGP 94169 Pipeline Pressure Flushing Services, an Item code, covers vacuum truck operations, jet rodding, hydro-blasting, and related pipeline and sewer-line maintenance work that state and local governments solicit to clean and maintain facility infrastructure including wastewater treatment plants, water treatment plants, storm drains, sewer lines, interceptor tanks, and basin structures. Recent solicitations by municipalities and special districts show demand for equipment-intensive services with firm technical specifications—vacuum trucks rated at 100 GPM @ 2,000 PSI, hydro-blasters capable of 10,000 PSI @ 32 GPM, and diesel-powered submersible pumps—paired with contractor qualifications requiring a minimum of five years' experience in vactor services and supervisory personnel with at least one year of demonstrated experience. Issuing bodies include city public works and water utilities departments (Phoenix, Ocala, Atlanta, Alpharetta, and Dallas), with multi-year requirements contracts and on-call arrangements typical of the procurement structure. Pricing is submitted on unit, per-item, or rate-sheet bases and remains firm-fixed; all labor, materials, equipment, transportation, mobilization, and disposal costs are incorporated into the bid.

Recent activity concentrates in Florida (Ocala's three-year stormwater cleaning and CIPP lining contract, ITB 260199, due July 6, 2026; Palm Beach's Sand Transfer Plant pipeline repairs, ITB, due August 20, 2026) and Arizona-Texas (Phoenix's five-year vactor requirements contract, IFB 27-0462, due October 19, 2026; Dallas Water Utilities' residuals handling improvements and wastewater rehabilitation projects). The City of Phoenix opportunity is the most current actively open solicitation under this code, with a pre-bid conference on October 5, 2026 and sealed offers due October 19, 2026 at 12:00 p.m., subject to DBE-N compliance under 49 CFR Part 26. The City of Atlanta's color video pipeline inspection and sewer cleaning equipment procurement (IFB GS/DWM/2604-1260190, June 23, 2026) and the City of Alpharetta's on-call pipe lining services RFP (26-115, May 28, 2026) illustrate the broader market for specialized equipment and trenchless rehabilitation methods including CIPP and spincast technologies. Confined-space certification, OSHA compliance, background screening, and proof of business licensure are standard contractor requirements across jurisdictions.
