Smart Water Valve saves
Co-op City $350,000
Almost three years ago, Co-op City in
the Bronx, New York, the largest public
housing development in the USA, was
seeking a simple, low-maintenance way
to reduce its water use and cost.
Barrett Green Management provided
a proprietary product that would save
Riverbay Corporation, Co-op City’s
owners, 10 per cent on its water bill
with virtually no maintenance.
A Barrett Green Smart Water Valve™
was installed in one of its ‘Tower’
buildings, which serves three 33-storey
high-rise residential buildings among
Co-op City’s 35 buildings.
The valve has since saved Co-op
City more than $350,000 since its
installation. Riverbay Corporation is
said to be pleased with the significant
monetary savings, lack of maintenance,
and the fact that they are preserving
water and the environment with the
valve.
Barrett’s managing director, Barry Korn,
explained, “The Barrett Green Smart
Water Valve functions as a check valve,
using our proprietary technology to
remove air from the water, and better
control its flow.”
Water contains 10 to 20 per cent air,
depending on its temperature and
pressure.
Eliminating air improves water flow,
reduces the amount of water used, and
therefore reduces the water bill. Mr Korn
added, “The valve is made from 100 per
cent ‘food grade’ stainless steel, which
makes it safe for drinking water.”
The valve is installed within a building’s
main water pipe. Because it is usually
placed in the basement, there is no
negative impact to the residents’
apartments. It is made to aircraft-level
tolerances for smooth and maintenance-
free operation.
The valve costs the building
management nothing. Instead, Barrett
Green Management receives a portion
of the savings resulting from the valve’s
use. With water rates rising consistently
in the USA, averaging 4 per cent over
the past three years in New York City,
owners and property managers have
an opportunity to offset these price
increases.

Tailor-made tube specialist
CSM was founded in 1981 as an
engineering firm for the design and
manufacture ofmachines andproduction
lines for tubular heating elements.
In 1983 a division for the production
of stainless steel tubing was created,
offering to the market high-quality TIG
welded stainless steel tubing in small
diameters and thicknesses, supplied cut-
to-length as required by the customer.
Starting with one production line in
1983, with a yearly production of 2.5mn
metres in three diameters, production
has now increased to 45mn metres per
year with sixteen production lines; tube
diameters range between 5 and 28mm,
in thicknesses from 0.3 to 1.5mm.
In addition to wider ranges of diameters
and thicknesses, since 2001 CSM Tube
has also supplied heat-treated tubing,
either in coils or in straight bars cut to
length up to 18m. CSM Tube operates
in compliance with the international
standards foreseen for the different
types of product and different final uses.
Pressure testing is carried out on 100
per cent of the heat-treated tubes
supplied in coils. Alloys normally used
are austenitic, AISI 300 series and
refractory nickel high content (alloys
800 – 825 – 840, alloys 600 – 601).
The company states that its constant
growth has been achieved thanks to the
quality of the supplied products, service,
competitiveness and continuous
technological innovation. The constant
search for new markets, new fields and
new specific requirements to satisfy has
been decisive. The high technological
level of the production lines allows CSM
high flexibility with low costs.
CSM Tube began the production of
stainless steel tubing for heating elements
and since 2003 has successfully supplied
products for use in a variety of sectors,
including tubing for heat exchangers,
domestic and industrial boilers, beer and
soft drinks coolers, and components for
the automotive sector.
