Denver Metro Facility – Wastewater Treatment Plant

Optimized Wastewater Sludge Handling with Continuous Conveyor Systems

Location: Denver, Colorado

The Denver Metro Wastewater Treatment Plant faced challenges in moving sludge through its large-scale facility. Serpentix conveyors were installed to transport materials across inclines, confined areas, and multiple processing stages. The system improved reliability, reduced manual labor, and provided a scalable solution to meet the demands of a major metropolitan treatment plant.

Challenges

Needed steep elevation gain in tight layout between centrifuges and overhead truck hopper
Required flexibility to switch between composting and liquid sludge land application
Conventional conveyors would’ve required multiple units and sharp incline angles

Serpentix Solutions

194’ Continuous Path Conveyor replaced need for 2–3 separate units

Achieved 64’ vertical lift with horizontal turning through tight facility layout

Conveyed sludge cake directly from centrifuges to hopper for compost transfer

32” belt, variable-speed motor (3–15 HP), rated for 60 tons/hour at 60 ft/min

Results

Seamless integration into Dual Utilization program (composting + land application)

Supported 75–105 tons/day sludge throughput

Enabled efficient truck loading of both liquid and solid sludge for regional distribution

Reinforced Metro Denver as an early innovator in biosolids sustainability
