Ontario Sluice Gate Solutions

Cast iron sluice gates are used to control flow on rivers, hydro dams, provide flood protection and irrigate farmland. They also serve to regulate, isolate and control flow through municipal sewage and water treatment facilities

Sluice gates are designed to move vertically from an open to close position utilizing an operating stem powered by a  manual gearbox, an electric actuator or a hydraulic cylinder.   

After years of use, the rebuilding of the sluice gate or any of its accessories may be in order. That's where we come in.

Our Process

  • Detailed project specifications are a necessary part of the tender documents on municipal projects involving water and sewage treatment facility upgrades or expansions.
  • 2020 Grealey Sluice & Slide Gate Consulting Inc. does advocate municipalities, plant managers and consulting engineers utilize  a site inspection supported by a detailed technical report to establish the physical condition of each installation before proceeding with gate specifications .    
  • Unfortunately, the question "What do we know about the existing gates?" is not raised often enough by owners, plant managers or consulting engineers. Often, excellent heavy-duty cast iron sluice installations are prematurely demolished and replaced by poor quality fabricated gates having a short service life.  
  • A detailed scope of work including specifications created for sluice gate or quality slide gate replacement or rehabilitation will do much to ensure the customer not only gets the best product, he will also witness successful completion of this important part of the project.
