What is Trenchless Technology? Trenchless Technology involves the rehabilitation of existing underground utilities such as water, sewer, storm, gas, and electrical conduits, as well as the installation of new underground infrastructure.Trenchless Technology uses methods that minimize the construction impacts associated with traditional open-cut construction methods.

Projects in Trenchless Technology
Over the last several years, Opus DaytonKnight has completed many trenchless technology projects.  Some of which are both innovative and at the forefront of trenchless technology in North America and the World.Including the award-winning project,

Benefits of Trenchless Technology


Reduced impacts resulting from less surface disruption to environmentally sensitive areas.


Construction impacts are minimized when compared to open-cut construction. There is a reduction in import backfill and pipe bedding, and minimal trench construction improves long-term sustainability of pavement.



Site safety is more effectively managed due to localized stationary worksite.


Trenchless construction minimizes traffic and noise impacts, two common complaints from the public due to traditional construction.


Where there are numerous existing services and/or where relatively deep excavation is required, trenchless construction can provide substantial cost savings.

Other products and services from Dayton Knight


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.


Odour Control

Chemical addition (ferrous chloride, ferric chloride, hydrogen peroxide, potassium permanganate, sodium hypochlorite). Compost biofilters (for scrubbing wastewater treatment process offgases and sewage pumping station wet well offgases). Trickling filter media for use as a biological scrubber. Biological scrubber towers (nitrifying and/or caustic). Covering and venting of structures.


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.



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.
