Independent testing by the University of New Hampshire and by DBO Expert Inc. of Bromtonville, Canada, comparing Enviro-Septic® systems with pipe and stone systems, proved conclusivley that Enviro-Septic® significantly outperforms pipe and stone installations. For example, the Enviro-Septic® system
allows, in steady state, several times the amount of effluent to pass through its biomat surface than pipe and stone.
disperses leachate more evenly than pipe and stone.
distributes cleaner leachate while allowing a smaller system footprint than pipe and stone.
reduces leachate contaminants to concentrations significantly lower than pipe and stone. (See three examples in the table below.)

The following graphs show that changes in septic tank effluent strength make little or no difference in any of the contents of leachate exiting Enviro-Septic® systems, but a great deal of difference in the contents of leachate exiting pipe and stone systems.
