This is a Request for Proposal (RFP) from the New Hampshire Department of Environmental Services (NHDES) Winnipesaukee River Basin Program for comprehensive cleaning services at the Franklin Wastewater Treatment Facility. The scope of work involves cleaning, dewatering, and disposing of residual solids from Secondary Digester Number 1 located at 528 River Street, Franklin, NH, with specific performance requirements including achievement of a minimum 24% cake solids and 95% solids recovery. Work must be completed between April 1, 2025, and May 16, 2025, with strict operational constraints limiting daily work to 8 hours (7:00 AM to 3:00 PM), Monday through Friday. Proposals are due by 3:00 PM on March 15, 2025. Firms are encouraged to arrange site visits and evaluate samples prior to submission. The project will be evaluated based on lowest total cost from qualified firms meeting all technical and safety requirements.

Contractors must provide their own power source, equipment, polymer, and watertight containers for material disposal, with all materials disposed of in accordance with federal, state, and local regulations. Payment is structured in three phases: 10% upon mobilization, 80% following satisfactory dewatering and verified proper disposal, and 10% upon completion and demobilization. Contractors must be registered with the New Hampshire Secretary of State's Office, maintain specified insurance coverage, and demonstrate technical competence in confined space operations and stormwater management practices. The RFP does not specify explicit set-aside designations or restrictions on participating organizations. No specific budget range is disclosed, though the detailed technical requirements and three-phase payment structure suggest a sophisticated project of potentially significant scope.
