Odor Control Chemicals

Fairfax County, Virginia is seeking comprehensive chemical and delivery solutions through Request for Proposal (RFP) 2000004191 for the Department of Public Works and Environmental Services (DPWES), Wastewater Collection Division. The procurement focuses on proactively mitigating hydrogen sulfide (H2S) formation in long-retention wastewater systems across eleven facilities, with the primary objective of addressing odor complaints, corrosion risks, and service continuity. Vendors must provide liquid chemicals, complete storage and feed systems, high-density polyethylene storage tanks, stainless-steel enclosures, advanced dosing controllers, and hydrogen sulfide monitoring equipment. The contract will require full equipment maintenance, monthly reporting, technical support, and an internet website for data access and remote monitoring. Evaluation criteria will include statement of qualifications, chemical performance, equipment compatibility, dosing and monitoring capabilities, service and support plan, and overall cost proposal, with weights ranging from 10% to 25% per category. The proposal is due on October 23, 2025, at 2:00 P.M., and vendors must submit sealed proposals through Fairfax County's procurement portal.

The RFP emphasizes equal opportunity and does not discriminate against faith-based organizations or bidders based on race, religion, color, sex, national origin, age, disability, or other protected characteristics. The contract encourages participation from small, minority-owned, women-owned, and service-disabled veteran-owned businesses. Vendors must be authorized to conduct business in Virginia, maintain a drug-free workplace, and comply with immigration laws. The initial contract period is three years with two potential one-year renewal options, structured as a firm-fixed price agreement with potential annual price adjustments based on the Consumer Price Index (CPI-U). Pricing will be structured per gallon of solution delivered, inclusive of freight and technical assistance. While specific budget ranges are not explicitly stated, the comprehensive nature of the required services—including chemical delivery, equipment implementation, and ongoing monitoring—suggests a substantial contract value. Vendors must provide detailed pricing for chemical products, new equipment installations, and comprehensive service packages, including maintenance, field sampling, technical support, and web-based monitoring.
