Siphon Cleaning Services

Charlotte Water, a department of the City of Charlotte in Mecklenburg County, North Carolina, is soliciting proposals for an annual sanitary sewer siphon cleaning program through RFP #FY26-RFP-11. The project aims to clean and inspect approximately 44 inverted siphons throughout their service area, covering pipes ranging from 6 to 48 inches in diameter, including single and multi-barrel configurations. The initial contract term is two years with options to renew for three additional one-year periods. A non-mandatory virtual pre-proposal conference is scheduled for September 24, 2025, at 11:00 a.m., with proposal submissions due on October 15, 2025, by 2:00 p.m. Contractors must provide comprehensive services including siphon cleaning, CCTV inspection of sanitary sewer lines, and post-cleaning documentation, with specific requirements for equipment, cleaning methods, and reporting. Evaluation criteria will likely include pricing, technical capabilities, references, safety records, and demonstrated experience with similar municipal infrastructure cleaning projects.

The City of Charlotte has established a Charlotte Business INClusion (CBI) program that encourages participation of Minority-owned (MBE), Woman-owned (WBE), and Small Business Enterprises (SBE). Vendors must complete MWSBE utilization forms, documenting their business classification and outreach efforts to maximize inclusion of diverse businesses. The bid table indicates a mobilization allowance of $35,000 and includes a 15% contingency allowance, suggesting a potential total project value that could range between $200,000 and $500,000 depending on the scope of cleaning and inspection services required. Contractors must provide comprehensive insurance documentation, including workers' compensation, commercial general liability, and professional liability coverage. The pricing structure allows for potential adjustments during renewal periods based on the Consumer Price Index for the South Urban Area, and contractors will be required to maintain detailed documentation of work performed, including weekly work schedules and inspection reports.
