NIGP 63550: Screens and Strainers

NIGP 63550 Screens and Strainers, an Item code, covers removal, replacement, and installation of filtration equipment in municipal water and wastewater systems, along with roadway safety screening and barrier applications. State and local governments procure strainers for water reclamation facilities to filter recycled process water for facility reuse, and screens for expressway guardrails, concrete barriers, and crash cushion installations that require protective or containment infrastructure. Issuing bodies include county governments managing water utilities and transportation infrastructure, with recent activity driven by maintenance and capital improvement projects at established facilities. The work typically involves direct replacement of existing equipment at specified sites, removal and disposal of superseded components, provision of gaskets and hardware, site cleanup, and travel, with contractors required to carry standard commercial general liability and workers compensation coverage.

State and local procurement activity under the code has appeared recently in Georgia and California. The Unified Government of Athens-Clarke County, Georgia issued IFB BID #26042 in May 2026 for removal and direct replacement of an automatic strainer at the North Oconee Water Reclamation Facility, with an estimated project budget of $125,000 to $175,000 and bids due June 12, 2026. An optional site visit was scheduled for May 19, 2026, and Addendum I issued June 1, 2026 clarified scheduling expectations and long lead times for strainer equipment. Santa Clara County, California solicited competitive bids in March 2026 through ITB ITBRDAFY260652 for Expressway Guardrail Replacement and Safety Barrier Improvements, with a mandatory pre-bid conference on April 14, 2026 and sealed bids due April 23, 2026; the project specified a 45 working day completion period commencing approximately 25–30 days following Notice of Award.
