Engineering

Wastewater Collection and Conveyance Systems

• Sanitary and combined sewers system design and analysis                           
• Vacuum wastewater sanitary sewer collection system design         
• Sanitary and combined sewer dynamic modeling and simulation for new and existing systems with customizable domestic wastewater load allocation (loading based on hydrographs, unit loads or pattern based loads) and stormwater load allocation based on well accepted infiltration, runoff (SCS runoff, CN with automatic CN weighting, Horton, etc) and time of concentration methods            
• Variable-speed pumping stations for energy-saving operation                   
• Combined overflow scenario analysis for varying future wastewater flows   
• Direct model GIS integration

Wastewater and Sludge Treatment Plants

• Wastewater preliminary treatment design, modeling and simulation for screens, grit and grease traps, primary sedimentation

• Wastewater chemical treatment design, modeling and simulation for enhanced primary sedimentation, Phosphorus precipitation, disinfection, etc
• Sludge treatment design, modeling and simulation for thickening, anaerobic and aerobic digestion, dewatering and disposal        
• Advanced sludge treatment design for advanced dewatering, drying, incineration or pyrolysis
• Biogas storage and treatment for electrical/thermal energy  generation/co-generation 
• Wastewater treatment plant design using well recognized static design  software (CapdetWorks, Denika, Wastewater Expert as per ATV-DVWK A-131)        
• Wastewater treatment plant sensitivity analysis using last generation dynamic simulation software (GPS-X, Denisim)           
• Existing treatment plants refurbishment and improvement to total compliance with local and federal environmental requirements

Landfill Methane Collection and Destroying

• Landfill gas collection system design and implementation
• Determination of GHG (Greenhouse Gas) assessment boundary as per Climate Action Reserve (CAR) and Verified Carbon Standard (VCS)
• Data acquisition system design and implementation for full compliance with CAR’s and VCS’s requiremets                           
• Data processing for carbon credits claim as per CAR’s and VCS’s requirements
• Landfill methane collection and methane destroying systems operation and maintenance
