The Hydrolite Survey Echosounder looks like a piece of equipment that may be useful to some.
How can one differentiate between the level of the sludge in a series of large septic system ponds and their true 'bottom/sides' in order to verify the volume of the pond ?

In my experience, it does not penetrate the "sludge"...stops at the first thing it encounters.
Look into the Knudsen Engineering, Ltd. Model 320 B/P dual frequency (28/200 kHz) Echo Sounding System. This system records echo sounder profiles georeferenced to output from a GPS receiver in digital format which can be converted to digital image formats for viewing.
The 200 kHz acoustic impulse provides approximately 1 cm vertical resolution and is used primarily to acquire detailed bathymetric (depth) data. The 28 kHz acoustic impulse can penetrate up to 10 meters of fine-grained lacustrine sediment to provide an indication of sediment thickness over basement in lacustrine basins. Thus, this system can provide data necessary to produce detailed bathymetric maps and sediment thickness maps from a single survey. QA/QC the survey with spot core samples.

sure.. .it will penetrate "fine-grained lacustrine sediment"...
But what about septic sludge??? 🙂
Just funnin'....
Tom,
Opps...I confused lacustrine sediment with latrine sediment.;-)
DDSM
Thank you all.
Cheers
