What Atlas Dewatering does

Atlas Dewatering Corporation is a Canadian specialty water management services company founded in 1946 and headquartered in Concord, Ontario. The company provides construction dewatering, temporary bypass pumping, environmental groundwater management, and discharge water treatment to construction, municipal, mining & quarry, pipeline, and power customers across Ontario and Quebec, delivered through seven physical branches and a 24/7 emergency response capability.

Its technical core is a portfolio of groundwater control systems — wellpoint systems for shallow excavations, eductor systems for low-permeability silts and fine sands, and deep well systems for coarse sands, gravels, and fractured rock — paired with engineered bypass pumping, HDPE pipe fusion (ISO 9001:2015 certified with in-house certified inspectors), weir/frac tank filtration, and a rental fleet of centrifugal, submersible, hydraulic submersible, and slurry pumps, generators, and light towers. The business is project-based and quote-driven, with revenue generated from professional services, equipment rentals, equipment sales, and certified fusion work.

Atlas is the only unionized, ISO 9001:2015 certified dewatering company in its market with in-house certified fusion inspectors, and holds Environmental Compliance Approval (ECA), Well Technician Licensed Contractor, and IHSA COR certifications that gate market entry. In September 2025, Atlas was acquired by Workdry International Group (parent of Selwood, Holland Pump, Siltbuster, and Vanderkamp), with Arcus Infrastructure Partners as majority shareholder, positioning Atlas as Workdry's North American dewatering platform and a beachhead for US expansion via Holland Pump.
