Interjurisdictional Wastewater Flow and Depth Meters

Fairfax County, Virginia is seeking proposals for a comprehensive wastewater flow monitoring contract through RFP 2000004223, targeting the procurement of equipment, software, installation, data hosting, analysis, and maintenance services for interjurisdictional wastewater flow and depth meters. The county currently manages a sewer collection system spanning over 3,300 miles of pipe with 70 pump stations, including 34 permanent flume sites, eight co-managed regional sites, approximately twelve manhole installations, and four rain gauges. Contractors must provide per-site pricing for 13 line items, including installation, field service, depth sensor maintenance, data collection and analysis, web-hosted data management, wireless service, and engineering analysis. Project managers must have a minimum of five years of flow metering experience, with at least two years in a project management role, and either an engineering degree or five additional years of metering experience. The proposal evaluation will be based on technical approach and method (40 points), firm qualifications and experience (30 points), key personnel and staffing (15 points), and cost proposal (15 points). An optional pre-proposal conference was held on December 17, 2025, with electronic proposals due by January 15, 2026, at 2:00 P.M. EST through the Bonfire procurement portal.

The contract will have an initial three-year period with options to renew for two additional one-year periods, contingent on County Board appropriations. While no specific set-aside designations are mentioned, the county emphasizes compliance with non-discrimination requirements and equal opportunity purchasing guidelines. The county currently uses the PRISM platform for data management but will consider alternative platforms with equal or enhanced capabilities. Insurance requirements are substantial, including Workers' Compensation ($1,000,000), Commercial General Liability ($1,000,000 per occurrence, $2,000,000 aggregate), and Automobile Liability ($1,000,000 per occurrence/aggregate). The pricing structure allows for firm-fixed pricing in the first 365 days, with subsequent year price adjustments based on the Consumer Price Index (CPI-U) or other relevant indices, subject to 60 days advance notice. While no specific budget range is explicitly stated, the comprehensive nature of the contract and the extensive infrastructure suggest a significant investment in wastewater monitoring technology and services.
