NIGP 63550 Screens and Strainers, an Item code, encompasses replacement and installation of industrial filtration equipment for municipal water and wastewater treatment operations. State and local governments procure under this code to maintain or upgrade screening and straining systems that remove solids from process water streams, typically at water reclamation facilities, treatment plants, and similar infrastructure. Issuing bodies include municipal utilities departments and unified governments operating water and wastewater systems.

Work was to commence within 10 days of written notice to proceed, with long lead times anticipated for equipment delivery. Addendum I issued June 1, 2026 clarified scheduling expectations and noted no firm completion deadline, though the agency indicated preference for expedited completion.
