Nu Flow
Until now, the only way to effectively protect
municipal water from water-borne contaminants
has been reverse osmosis. This is
no longer a practical solution,
as it only filters water at one
plumbing fixture. Nu Flow’s
solution is the Aqua Source
Guardian. This system is
approved by the National
Sanitary Foundation and
requires very little water for
flushing out impurities. The
system removes disinfectant
by-products, sedimentation,
and pesticides down to .02 microns, providing
clean, safe water from every tap. For
more information, contact Nu Flow at (800)

Poly-Triplex
Poly-Triplex Liner System has proven
longevity with a track record of success in the
wastewater environment, with more than
10,000 structures lined and more than 1,000
structures installed over 10 years. The patented
Poly-Triplex Liner is a three-layered, fiberglass
and epoxy system
that contains a
vital internal nonporous
membrane.
Once saturated at
the jobsite, the liner
is cured-in-place
using a patented system
of air pressure and steam, forming a laminated
composite bonded to the host structure.
Pressurized into the pores, cracks and crevices
of the surface, the resin bond prevents the
liner from being pushed off from groundwater
infiltration. The internal non-porous membrane,
encapsulated in the center of the laminated
composite, provides a permanent barrier
to gas penetration through the liner, halting
chemical attack of the host structure, as well as
providing a permanent barrier to prevent infiltration
of groundwater into the collection system.

and great suction lift performance make
the DV-200c the best choice for tough
pumping projects.
The galvanized trailer
resists corrosion,
eliminating expensive
repainting costs.
Flows up to 4,500
gpm and heads up
to 260 ft make the
DV-200c a leader in pump performance.
