    Services - Commissioning

    Controls and instrumentation, so closely related to SCADA installations, receive an extensive loop checkout procedure that includes the final calibration of all related equipment. At the same time, our water or wastewater engineers verify the system, and provide the initial training to the operator on the operations and maintenance of the system.


    Services - Biosolids Management

    The research effort studies if operating conditions such as feed sludge composition, digestion temperature, and sludge retention time can be optimised for improved dewaterability of thermophilically digested biosolids. To manage the sludge that is generated from wastewater treatment units, Opus DaytonKnight incorporates digestion technologies like ATAD and Thermophilic Anaerobic Digestion.



    Where there are numerous existing services and/or where relatively deep excavation is required, trenchless construction can provide substantial cost savings. For more information on our capabilities and experience in trenchless technology or other consulting engineering requirements. Site safety is more effectively managed due to localized stationary worksite. Construction impacts are minimized when compared to open-cut construction.



    We are especially proud of our efforts to assist our clients with public and regulatory liaison and consultation programs. To view information about some our past projects.
