In our Tuesday webinar we've heard a lot about the need for better tools, and we've heard about some more high-end tools that have been developed. What about lower cost tools? A perfect tool would be inexpensive, fast, versatile, able to handle trash, able to handle thick or thin sludge, and be able to be used cleanly.
I've done work over the years to develop the sludge digger, a scoop on a pivot that is at least an improvement beyond a shovel or bucket. You can work through the drop hole in most cases. It handles trash and thick or thin sludge. See the video at:
I've also done a manual sludge pump, perhaps around $200-300, that handles trash pretty well, and is fairly fast. It's a bit bulky to transport if you don't have a wagon or truck. See the video at:

Both of these, but especially the pump, were field tested with help from the people at Sanergy, so many thanks to them, particularly Thomas Onsati.
