Grit and Screenings Transportation for WWTP

The City of Benicia (“City”) is requesting proposals from qualified organizations to assist the City in the transportation of grit and screening materials from the City of Benicia Wastewater Treatment Plant (“WWTP”) located at 614 East 5 ^th Street, Benicia to the Keller Canyon Landfill, located 15.6 miles away in the City of Pittsburg, California.

The City of Benicia is a general law city located in Solano County. The grit and screenings are removed from the wastewater in process and mechanically dewatered. The plant produces approximately 30-40 tons of grit and screening material per year with significantly more in years that include digester cleaning operations, next due in 2029. Individual loads are collected and transported in a 10-yard dump box and typically weigh 3-6 tons. The grit and screenings are tested for various constituents, and a waste profile including waste manifests is in place with Keller Canyon Landfill. A summary of analytical testing data and waste profile information is available upon request.
