NIGP 91187: Storm Drainage

NIGP 91187 Storm Drainage, an Item code, encompasses the installation, repair, rehabilitation, and maintenance of stormwater collection, conveyance, and treatment systems that state and local governments procure to manage runoff and prevent flooding. The code captures a wide mix of work: new storm sewer line installation and replacement, pipe rehabilitation and lining, inlet and structure repair, pond dredging and embankment restoration, drainage retention and detention system design, erosion control and site stabilization, and ongoing maintenance of retention areas and ditchlines. Recent solicitations show cities, counties, and special districts actively purchasing design services for comprehensive drainage improvements, construction of stormwater infrastructure in residential and commercial settings, and specialized services such as CCTV inspection, spin-cast pipe rehabilitation, and septic-to-sewer conversion including force-main installation. Issuing bodies span a broad geographic and jurisdictional range: municipal public works departments (Casselberry, DeBary, North Miami Beach, Oviedo, Orlando, College Park, Statesboro, Bend), county boards and school districts (Greenville County South Carolina, Pinellas County Schools, Clay County Florida, Escambia County, Orange County Florida, Collier County, Glynn County Georgia), regional transit authorities (Greater Orlando Aviation Authority), special authorities (Atlanta Beltline, Liberty County Georgia, Berrien County Board of Education), and smaller municipal entities (Marietta Georgia, Covington Georgia, Walnut Grove Georgia, Guyton Georgia, Blakely Georgia, Parker Colorado, Richardson Texas).

Recent activity clusters heavily in Florida and Georgia, with secondary concentration in South Carolina, Colorado, and Texas. Representative recent opportunities include the City of Casselberry, Florida SOQ for stormwater and lakes management consulting services with a five-year term and project fees capped at $200,000 per task (multiple qualified consultants awarded); City of DeBary, Florida Small Scale Stormwater Improvement Projects 5 and 6 (IFB with bids due October and December 2019, engineer's estimate $153,196 to $297,382); Greenville County, South Carolina Suffolk Drive Drainage Improvements (IFB27023, bids due October 21, 2026, mandatory pre-bid); Escambia County, Florida CDBG-DR Oakfield-Palafox Stormwater Upgrades Phase III (ITB with Section 3 employment requirements, bids due August 24, 2026); Orange County, Florida Underdrain Installation & Repair (Y26-1003, estimated five-year cost $19.6 million, multiple awards possible); Collier County, Florida Immokalee Sports Complex Phase 1A & 1B stormwater improvements (IFB 26-8703, anticipated budget $6.24 million, bids due November 2, 2026); and Greater Orlando Aviation Authority pond dredging at Airsides 1 & 3 (IFB 26-995, approximately 41,500 cubic yards sediment removal, bids due October 23, 2026). Federal funding through CDBG-DR, EPA, and HUD sources is common; Davis-Bacon prevailing wage requirements and Section 3 employment obligations frequently apply. Participation goals for MBE, WBE, SBE, and local vendors appear in many recent procurements, and pre-bid conferences are standard. Contract values range from under $200,000 for small municipal drainage projects to over $6 million for regional infrastructure initiatives, with three- to five-year terms typical for on-call or indefinite-quantity arrangements and 45 to 365 calendar days standard for single fixed-scope construction.
