Sonar Mapping Services

Turn Sonar Data Into Better Decisions

Drylet Sonar Mapping creates detailed maps of sludge depth and subsurface conditions across lagoons, basins, and other wastewater systems. The resulting data helps operators understand where solids have accumulated, estimate available capacity, and make more informed decisions about treatment, solids management, and next steps.

Whether you're investigating a performance issue, planning maintenance, evaluating treatment options, or simply need to know what's happening below the surface, sonar mapping gives you real data to work from instead of assumptions.

Know What’s Beneath the Surface

Your lagoon may look fine from the surface, but that doesn’t tell you what’s happening below. Drylet Sonar Mapping combines sonar and GPS technology to map sludge accumulation and subsurface conditions across your lagoon or basin.

The resulting data provides a clearer picture of where solids are accumulating, how sludge depth varies across the system, and how much usable capacity may remain—giving you real information to guide your next decisions.

Key Benefits of Sonar Mapping

  • Measure Sludge Accumulation: See where solids have accumulated and understand sludge depth across the lagoon or basin.
  • Estimate Available Capacity: Understand how much usable capacity may remain in your system.
  • Identify Problem Areas: See variations in sludge accumulation that aren't visible from the surface.
  • Establish a Baseline: Create measurable data for future comparisons and solids-management planning.
  • Plan Your Next Steps: Use real subsurface data to help evaluate treatment, maintenance, dredging, or other solids-management options.

Position, Company name

We added ManureMagic® to the pits of each of our grower/finisher barns and within a few weeks the odor was cut by 50-75%. Being on the west side of a major highway, we wanted to remain proactive with odor control. We have been looking for something to help us with odor, and I think we’ve found the answer. ManureMagic® is easy to work with and has a pleasant smell. We strongly recommend ManureMagic®.
