Presently, the City’s two activated sludge wastewater treatment plants produce an annual yield of approximately 2,068 dry tons/640 loads of de-watered sludge cake at 16 to 24 percent (%) solids content. The de-watered sludge cake is then transported from the Southwest Water Reclamation Facility (SWWRF) located at 1551 S. Maple Leaf Drive and the Dallas Salmon Wastewater Treatment Plant (DSWWTP) located at 703 N. Wisconsin Avenue, to a Texas Commission on Environmental Quality (TCEQ) permitted compost site. Incidental liquid sludge loads are transferred between DSWWTP and SWWRF approximately 6 miles one way. Quantities are estimates based on historical sludge production and are not guaranteed for the term of contract.
Grit screenings from the above-mentioned treatment facilities will be disposed of at the TCEQ permitted landfill. These facilities currently produce approximately 10 loads or 200 cubic yards annually.
The City’s Wastewater Department recommends Wastewater Transport Services LLC be awarded the contract for three years in an amount not to exceed $1,871,760, with two additional one-year renewal options available.
