EPA Verification of tommy vs Trencher
The Scientific Verification arm of the EPA – the
Environmental Technology Verification Center – organized
a panel of industry specialists and DOT directors, who designed
and operated the verification protocol for a comparison of the
tommy installation method and traditional trenching. Their conclusion
was that the tommy is 3-5 faster than the standard trench
method, while producing “consistent, dependable results.” Click
