Dredge and Bioaugmentation Monitoring

Smarter Dredging and Bioaugmentation Starts with Better Data

Precise sludge mapping for targeted, cost-effective results

At Hydrasurvey, we help you:

  • Map sludge with precision

  • Make data-backed decisions

  • Maximize efficiency

Tight budget? No problem.

Targeted monitoring ensures every dollar goes toward high-impact zones.

What This Service Includes

Pre-Dredging / Treatment Surveys

Understand starting sludge levels and set benchmarks and budgets

Mid-Project Checks

Validate progress, adjust plans or budgets as needed

Post-Treatment Surveys

Confirm results and measure amount removed / treatment success

  • Sludge blanket distribution thickness map for dredging

    Sludge Blanket Thickness Maps

    Sludge blanket thickness maps provide a clear visual of where your sludge buildup occurs and how it’s distributed across the bottom of your lagoon or pond. These maps are an excellent visual when dredging, they display what progress has been completed.

  • 3D sludge map 3D sediment maps

    3D Sludge and Sediment Maps

    3D sludge / sediment maps are provided to display your lagoon or ponds sludge characteristics. They can be provided to contractors for improved efficiency.

  • Liner measurements using a GNSS mounted survey rod taken

    GNSS Liner Maps

    We manually measure the liner using a GNSS mounted survey rod to provide you with liner elevation maps. This also increases the accuracy when quantifying sludge and sediment volumes.

  • Sludge sampling using a Eckman sludge sampler

    Sludge & Sediment Samples

    We collect and test, at an accredited lab, sludge or sediment samples to determine composition. Composition is required to calculate sludge / sediment volume and provide you with dredging disposal options.

  • RTK fixed survey GNSS

    RTK GNSS Positioning

    Using RTK GNSS positioning to map your sludge or sediment blanket provides you to the most accurate data.

  • Virtual Site Tour

    Our site tours include an aerial map or panoramic photos captured during the survey, with inset images highlighting key findings. This helps identify mechanical or infrastructure issues that might be missed from a single vantage point.

Visual Tools for Deeper Insight

Sludge Blanket Thickness Maps

  • These maps provide a clear visual representation of sludge accumulation in your wastewater treatment system.

  • Used before and after dredging, they highlight how much sludge was removed and where the buildup remains.

3D Sludge Maps

  • Ideal for municipalities, consultants and contractors, these maps allow users to fly over the lagoon system, pinpointing key features and areas of concern.

  • Perfect for presentations to management or councils, improving transparency and decision-making.
