The following pictures show the progress of the test conducted September 28, 2005.

The test was to see the effects of pumping directly on to a flat surface (on-site spread) and if the resulting effluent setup the same as it does in a dump truck box (hauling for landfill cover).

The approx. total amount of the fluid was 4500 us galAprox. run time 57 min. (start time 11:06 end time 11:59)Average flow 79 gpm.

Test was successful!
