One of the issues often overlooked
in discussions about
potable water quality, compliance
and safety is the storage
of domestic water. Pocono Fabricator's
Pre-Krete Tankliner-61, a recently
developed product designed exclusively
for lining the inside of domestic water
storage tanks, is now available and
meets NSF Standard 61. NSF Standard
61 specifically ensures that drinking
water contact materials and components
will not add harmful levels of contaminants
to drinking water.
NSF International, founded in 1944
as the National Sanitation Foundation,
is known for the development of standards,
product testing and certification in
the areas of public health safety and protection
of the environment. Canada's
CSA International also approves products
for use in potable water. They too
have adopted NSF Standard 61 as their
conformance criteria.
The Pre-Krete Tankliner-61 was developed
in June 1999 as a lining for installation
in hot and cold potable water
tanks. It is a hydraulic cement formulated
with a bauxite based binder, graded
aggregate, and specialty ingredients designed
to provide effective protection
against the corrosive effects of hard and
soft water. The specialty ingredients
control water retention, compressive
strength, set time, and workability, all
of which ensure that the end product applies
and performs as expected.
The sources for the graded aggregates
are selected on the ability of the
vendors to monitor the grain size of the
aggregates as well as product purity.
Most sand and/or stone supplies contain
clay, lime, dirt, etc., all of which will be
attacked in a corrosive environment.
There is also concern that these aggregates
may contain contaminants that are
harmful when ingested. Many sand/
stone supplies contain lead and arsenic.
Tankliner-61 can be used to line new
tanks or to repair and restore existing
tanks. It can even be applied over a
rusted surface provided there is no lamination
of the oxidized metal. This eliminates
the need for sandblasting, an expensive
procedure when using epoxy-based tank liners.
Provincial Tank Lining and Inspections
serves as the exclusive lining representative
for Clemmer Technologies,
a leading manufacturer of water storage
tanks and other containment systems.
Clemmer now installs only Tankliner-
61 linings in the new water storage tanks
they fabricate in their factory in Waterloo,
Ontario.
