selection. Also, an inspection program should be implemented
for critical valves, as well as pumps or monitoring equipment
that is in the reclaimed water flow. Finally, users should communicate findings of any in-service issues to the manufacturer
providing as much information as they can.
The future of this segment of the valve industry belongs to
those that are actively involved already and experiencing its
growth. For manufacturers, knowing the customer applications is critical as well as getting feedback on what is successful and what is not in each particular reclaimed water
environment. Controlled programs of endurance testing with
actual reclaimed water samples are valuable; however, care
must be taken to maintain the chemical composition and concentration unless an onsite test can be arranged using the
direct supply of the reclaimed water. Accelerated testing
methods also are useful to gain insight on factors such as elevated temperatures and higher concentrations. These factors
can be considered independently or combined. The testing can
be implemented on either independent valve components or
with entire valve assemblies—depending on the results
desired. Establishing a working relationship with various end
users provides an extremely beneficial flow of information
and can open up opportunities for controlled in-field testing
of new developments. Similarly, treatment plants that are
supplying the reclaimed water can be an excellent resource
for understanding chemicals currently in use as well as future
trends and changes. Such plants also can provide a listing of
reclaimed water users—both current and upcoming—as they
bring new customers into the distribution.
WHERE TO FROM HERE?
There is no doubt that use of reclaimed water will continue to
increase in irrigation applications, as well as in other direct
applications. This creates an opportunity for valve manufacturers to come up with new technology. New material development and the cost-effective use of existing materials in new
ways are already under study and those who wish to compete
will need to keep pace. At the same time, the irrigation valve
world is not one that has traditionally been enthusiastic about
change—a consistent, durable and reliable design that is easily maintained has taken precedence over the latest potential
However, this may change going forward as the opportunity to breathe new life into this segment of the valve industry is born—an opportunity that could mean drawing from
the experiences of other segments of the industry such as
nuclear and petroleum applications. What’s more, reclaimed
water is an opportunity for industry to be a critical part of
protecting, preserving and even improving one of our most
precious limited natural resources—the water we need for
almost everything in our lives. VM
