Bathymetric Survey of Effluent Ponds

project overview

Integrated Sustainability conducted a bathymetric and aerial survey of 6 effluent ponds to quantify sludge accumulation and available freeboard. The survey supported regulatory reporting and informed future sludge removal, pond modification, and biological treatment trials.

project deliverables

• Performed unmanned sonar and aerial drone surveys across 6 treatment ponds to capture sludge depths, water levels, and dike elevations.
• Generated 3D models and calculated sludge volumes and available freeboard using dual-frequency sonar and georeferenced site data.
• Identified priority ponds for future treatment trials based on sludge uniformity and survey data quality.
• Provided orthoimages, elevation models, and survey control points to support ongoing monitoring and infrastructure planning.
