FREE to members.
Fee for non-members $30+HST.


As the environmental risk of aging wastewater lagoon and retention pond infrastructure across Canada increases, so do the costs of dredging and upgrading these pieces of critical infrastructure. Many municipalities begin these capital-intensive projects with very little actionable data to help them plan, budget and develop a quality management strategy to execute a successful dredging project, leaving them susceptible to huge cost overruns, project delays and non-performance.

A comprehensive lagoon or pond sludge survey is an affordable, efficient tool with multiple datasets designed to provide operators, managers and engineers with the data they need to successfully execute these projects.


At the completion of this one-hour OJT session, participants will be able to demonstrate the following:

              • A general overview of comprehensive sludge survey methodology.
              • The importance of 3rd party sludge surveys.
              • How to use the data to plan and budget for a lagoon or pond dredging project.
              • How the data helps to monitor sludge accumulation or dredging progress and verify dredge project completion.
              • How the surveys assists to assess lagoon treatment system performance and diagnose lagoon issues.

  • Facilitator:

    Andrew Ambrocichuk

    Our facilitator is Andrew Ambrocichuk, the founder and CEO of Hydrasurvey Ltd., Canada’s leader in lagoon and pond sludge surveys and dredge project quality management. Andrew has been conducting sludge surveys on wastewater lagoons and ponds in Canada for almost a decade and during this time he learned that collecting accurate sludge blanket data is critical to successfully managing a wastewater lagoon or pond. Andrew founded Hydrasurvey in 2017 based on an industry-wide need for professional, 3rd party lagoon and pond sludge surveys to provide municipalities, wastewater engineering consultants and dredge contractors with the proper data to plan, budget and execute lagoon dredging and treatment infrastructure upgrade projects.
